Redundant System Manager Module Description

You can install a redundant system manager module in the PortMaster 4 chassis to provide system manager backup. The manager modules must be installed in slots 4 and

5 and must be physically identical to each other. One, usually the module in slot 4, functions as the primary manager, and the backup module is called the secondary manager.

Overview of Redundant Manager Operation

By installing a redundant system manager module, you can prevent PortMaster 4 downtime due to manager module failure. With two manager modules installed, if the primary manager fails, the secondary manager takes over. Although all active calls are dropped during failover to the secondary manager, power to the entire system is never interrupted and call traffic resumes as soon as the secondary manger takes over as primary and resets the individual line boards.

When operating the PortMaster 4 with a single manager module, you must install the module in slot 4. You install the backup manager module in slot 5. When you boot the system for the first time, the module in slot 4 starts up as the primary manager and the

module in slot 5 starts up as the secondary. (See “Primary Manager Module Selection at

Startup” on page 1-18 for details.)

1-1

Redundant System Manager Module Description

Each system manager module consists of a manager board and an Ethernet 10/100Mbps board. The manager board manages and administers the installed line boards. The manager board communicates with installed line boards at 155Mbps speeds through an embedded Asynchronous Transfer Mode (ATM) cell-switching network linked to the chassis’ passive backplane. Manager modules communicate with each other via a 115Kb universal asynchronous receiver/transmitter (UART) channel.

Physical Characteristics of a Manager Module

Each manager module provides the following (see Figure 1-1):

• C0 port—for a console connection with a null modem cable or for an asynchronous connection to an external modem

– The green LED on the C0 port is illuminated when the manager module is the primary manager, and not illuminated when it is the secondary manager

– The green LED on the C0 port blinks when the manager module has not yet determined if it is the primary or secondary manager

– The amber LED on the C0 port is illuminated when it receives a message from the other manager module

• C1 port—for an asynchronous connection to an external modem

• Ether0 interface—10BaseT Ethernet interface for a private LAN connection

• DIP switch 1 (bottom) and 2 (top)—to set C0 function and the boot mode of the manager card

• Ether1 interface—10/100BaseT Ethernet interface for an upstream Ethernet connection

• Media-independent interface (MII) connection—alternative Ether1 interface that accepts optional adapters for connection to copper or optical media

• DIAG LED—lights when the module is booting and blinks off every 5 seconds during normal operation

• PWR LED—remains solidly lit when the module is receiving power during normal operation

Installation and Configuration Requirements

To install and configure a redundant system manager module, you must have the appropriate hardware and software and must take the proper safety precautions.

Verifying Hardware and Software for Redundant Operation

Before installing and configuring the redundant manager module feature on your

PortMaster 4, make sure of the following:

1.

Verify that your PortMaster 4 chassis has the Revision C backplane.

Check the backplane for the revision letter C. The revision letter is located behind slot 2.

2.

Make sure that both system manager modules are capable of redundancy.

Verify that the model number on each module ends in R. Or check the label on the box that each module was shipped in for a manufacture date after July 1999.

3.

Verify that both system manager modules have ComOS 4.2 loaded.

Warning –

Use of a version earlier than ComOS 4.2 can damage PortMaster 4 hardware.

Installing and Working with the Redundant System Manager Module 1-3

Installation and Configuration Requirements

Safety Precautions

Warning –

(DC models only) Before working on equipment that is connected to power lines, remove jewelry such as rings, necklaces, and watches. Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

If an electrical accident occurs, turn off the emergency power switch for the room in which you are working, cautiously unplug the system’s power, and get medical assistance for any injured person.

Warning –

To avoid damaging the internal components of the PortMaster 4, follow antistatic precautions by wearing a grounding wrist strap.

Grounding Wrist Strap Instructions

When working with the internal components of the PortMaster 4, you must wear a grounding wrist strap. Grounding wrist straps can be attached either at the front of the chassis behind the power bay door, or at the back of chassis in the lower right and left corners.

Figure 1-2 shows the proper place to attach a grounding wrist strap at the front of the

chassis.

Installing a Redundant System Manager Module

Procedure

Follow these instructions to install the redundant manager module.

1.

Line up the edge of the module with the card guide in slot 5 (Figure 1-4).

Note –

The physical slots are numbered 0 through 9 from left to right. Although a manager module is physically installed in slot 4 or slot 5, the Ethernet board of the module functioning as the primary manager is monitored through virtual slot 10.

2.

Insert the manager module in slot 5, gently guiding the module into the slot.

If you have trouble sliding the module into the card guide, gently wiggle it back and forth to help it slide in.

3.

When the module is completely inserted in the slot, close the top and bottom tabs so they are flush with the face of the chassis.

Closing the tabs causes the module to connect with the backplane.

DIP Switch Settings

The DIP switches on each manager module are located between Ether0 and Ether1 (see

Figure 1-5). Each switch is off when turned to the left, and on when turned to the right.

• DIP switch 1 turned to the left forces the C0 port to transmit at 9600 baud, 8 bits, no parity, and 1 stop bit for use as a console port. When switch 1 is turned to the right, C0 can be configured as an asynchronous port.

• DIP switch 2 turned to the left sets the PortMaster 4 for netbooting. When switch 2 is turned to the right, the PortMaster 4 can boot normally.

Procedures for netbooting are located at

http://www.livingston.com/tech/technotes. Scroll to PortMaster

Troubleshooting, click Netboot Procedures, then select the procedure for your platform.

Figure 1-5 shows the location of the DIP switches on the manager module.

Connecting an Ethernet Cable

The PortMaster 4 supports the following Ethernet connections on each manager module:

• 10/100BaseT—used as the primary uplink. This Ether1 interface is located on the

Ethernet board but powered from the manager board. It is used for syslog,

traceroute, Telnet, RADIUS, ChoiceNet, the Domain Name System (DNS), and

TFTP.

• 10BaseT—used for private network management. This Ether0 interface is physically located on the manager board.

1-10 PortMaster 4 User Manual Addendum

Connecting an Ethernet Cable

• Media-independent interface (MII)—used to connect other wiring types (copper or fiber, for example) to the 10/100BaseT Ethernet. Devices attached to the MII interface must be MII-compliant.

Lucent strongly recommends that you configure and connect lines to both Ether0 and

Ether1 interfaces on each manager module. These interfaces must be on different

Ethernet subnetworks.

However, because Ether1 interface on the redundant manager inherits its IP address from the primary manager, be sure to connect the Ether1 interface on the redundant manager to the same subnetwork as the Ether1 interface on the primary manager

module. (See “Configuring the Ethernet Interfaces” on page 1-15.)

Ethernet 10/100BaseT

When using a PortMaster 4 with a redundant system manager module, you must configure the Ether1 interface on both manager modules. The Ether1 interface has the following characteristics and functions:

• Resides on the Ethernet board, which receives power from the manager board. The

Ethernet board and the manager board make up the manager module

• Communicates with the manager board over the PortMaster 4’s passive ATM backplane

• Contains a CPU for inbound data and a CPU for outbound data

• Remains active during low power or excessive heat conditions

• Is generally used to carry network traffic

Note –

The PROM of the Ethernet card attached to the manager module contains the

MAC address, which is actually a MAC address range. Conceptually, the Ethernet card has the MAC address, and MAC addresses for other devices in the system are software assigned from the address range based on the Ethernet card’s MAC address. The primary manager in slot 4 assigns MAC addresses immediately after bootup. During failover, system components retain the MAC address assigned by the primary manager in slot 4.

Follow these instructions to connect an Ethernet cable to the Ethernet 10/100BaseT interface

Required Equipment

One of the following:

Category 5 twisted pair cable, as specified by the EIA/TIA-568-B wiring standard,

with an RJ-45 connector (See “RJ-45 Cable” on page A-2 and “Ethernet Cable

Specifications” on page A-3 for more information.)

PortMaster 4 User Manual Addendum

Configuring a Redundant System Manager Module

Configuring a Redundant System Manager Module

Before following the instructions in this section, you must have installed a redundant system manager module in slot 5 of a fully configured, functioning PortMaster 4. Use the following procedure to copy the PortMaster 4 system configuration to a redundant manager module:

1.

Review “Installation and Configuration Requirements” on page 1-3 to

make sure you are ready to configure.

2.

Connect to the primary manager module in slot 4 via the console or an

Ethernet port and enter the following command:

Command> save all

This command copies the system configuration from the primary manager module to the redundant (secondary) manager module’s nonvolatile memory.

You can now configure the redundant manager’s Ethernet interface.

Configuring the Ethernet Interfaces

When you install a redundant system manager module in a fully configured, functioning PortMaster 4, you need to configure only the Ether0 interface on the redundant manager. The redundant manager inherits its Ether1 interface IP address from the Ether1 interface of the primary manager during failover.

The IP address you assign to the Ether0 interface on the redundant manager can be in the same subnet as the Ether0 address on the primary manager, but Ether0 addresses for either manager module must be in a different subnet than the address of the Ether1 interface. See Chapter 4, “Configuring an Ethernet Interface,” in the PortMaster 4

Configuration Guide for a complete discussion of Ethernet interfaces.

Use the following procedure to assign an IP address to the redundant manager and activate the configuration:

1.

Connect to the secondary manager in slot 5 via the console port and use the following command to assign an IP address and netmask:

Command (Secondary)> set Ether0 address Ipaddress [/NM] [Ipmask]

To communicate with the redundant module on the network, you must assign it an

IP address.

2.

Enter the following commands to activate the configuration:

Command (Secondary)> save all

Command (Secondary)> reboot secondary

The save all command, entered on the redundant manager, saves the configuration to nonvolatile memory on the secondary manager.

When using a redundant manager, entering the save all command on the primary manager console saves the configuration to nonvolatile memory on both manager modules.

This command reboots the entire system. You can enter this command from either manager.

This is the highest-level reboot command.

This command reboots the secondary manager module and can be entered from either module.

Rebooting the secondary manager does not affect the current operating parameters of the system.

It just ensures that the secondary manager is running the current code and that its configuration is up-to-date.

If you enter this command on the primary manager, it disconnects all calls and shifts the primary responsibility to the secondary. If you enter this command on the secondary, it reboots the secondary and has no effect on current

PortMaster 4 operation.

To better understand the reboot commands, note the defaults:

• Entering reboot without an argument from the primary manager reboots the entire system—just like the reboot

system command.

• Entering reboot without an argument from the secondary manager reboots only the secondary.

This command is an alternative way to reboot the secondary manager. It has the same effect as the reboot

secondary command.

These commands display the messages sent over the UART channel between the primary and secondary manager modules to the screen of your console session.

These commands turn debug mode off and redirect all debug output to null.

Primary Manager Module Selection at Startup

The PortMaster 4 uses the following criteria for primary manager module selection when you turn on the unit:

1.

A manager module is primary if it does not encounter another manager module for

4 seconds during the boot-up process.

2.

If two manager modules boot at the same time, the manager in slot 4 is primary and the manager in slot 5 is secondary.

After boot-up, the secondary manager sends hello messages at 1-second intervals to the primary manager and the primary manager responds.

See “Handling System Manager Module Failure” on page 1-23 for information about

manager module failover and replacement.

SNMP Alarms Supporting Redundancy

The SNMP alarms shown in Table 1-2 have been added for events related to the

redundant system manager module feature. These alarms are valid for either slot 4 or slot 5. When slot 5 is primary, the slot numbers in the message are reversed.

Table 1-2

SNMP Alarms for Redundant Manager Module Events

Alarm

Slot 4 becoming primary manager.

Description

This alarm, reported by the primary manager, is generated when a system manager module recognizes itself as the primary manager. This event can take place after the bootup decision process or after a failover has occurred.

Secondary manager detected in slot 5.

Can’t hear manager in slot 4.

Description

This alarm, reported by the secondary manager, is generated when a system manager module recognizes itself as the secondary manager.

This alarm is generated by the secondary manager module after it fails to get a response to its hello messages for 5 seconds—five hello messages are ignored by the primary manager module.

This alarm, reported by the primary manager, is generated when the primary manager does not receive hello messages from the secondary for 30 seconds.

This alarm is generated by the primary manager module when it detects a secondary manager module in slot 5. This alarm conveys the same information as “Slot 5 becoming secondary manager,” except that it is reported by the primary module.

This alarm is generated when the communication between managers fails. The manager module in slot 5 determines that the manager in slot 4 is still running because it can still detect a heartbeat.

Using PMVison 1.8 with a Redundant System Manager Module

Note –

Be sure to use PMVision 1.8 on a PortMaster 4 with a redundant system manager module. Earlier versions of PMVision and the older programs pminstall, PMconsole, and PMconsole for Microsoft Windows do not recognize the redundant system manager module feature and view each manager module in the PortMaster 4 as a separate system.

PMVision automatically handles both system manager modules transparently. If you connect to a PortMaster 4 using the Ether0 interface of the manager module in either slot 4 or slot 5, PMVision automatically contacts both managers and determines which is primary. You can display information about both managers by selecting the Configure

Boards option.

Figure 1-14 shows a display for a PortMaster 4 with a redundant manager module. For

more information about PMVision, see the PMVision User’s Guide.

Handling System Manager Module Failure

This section explains the failover process for the primary system manager module and provides instructions for troubleshooting communication between the manager modules, replacing a failed manager module, and upgrading a replacement manager.

Primary Manager Module Failover

Primary manager module failover on the PortMaster 4 proceeds as follows:

1.

If the secondary manager module does not receive responses to five consecutive hello messages, it listens for the heartbeat of the primary.

2.

If it detects a heartbeat, the secondary does not take over as primary manager but generates a “Can't hear manager in slot 4.” SNMP alarm.

3.

If the secondary manager does not detect a heartbeat from the primary, it takes over and becomes primary.

4.

The new primary manager reboots the system. All calls and network connections to the PortMaster are dropped, and dynamic routing information is lost.

Heavy traffic on the primary manager can temporarily impede manager-to-manager communication. This normal condition can create a failover-like situation. See

“Troubleshooting Communication between Manager Modules” on page 1-24 for details.

Installing and Working with the Redundant System Manager Module 1-23

Handling System Manager Module Failure

Troubleshooting Communication between Manager Modules

A burst of heavy traffic on the primary manager can cause temporary loss of communication over the 115Kb UART communications channel between the primary and the secondary manager modules. This behavior can appear very much like a failover. To troubleshoot the UART channel for possible failure, follow this procedure:

1.

Check for the following two events, which can indicate channel failure:

a.

The secondary manager does not detect a heartbeat from the primary and generates a “Primary manager in slot 4 failed.” SNMP alarm. If you can verify

that the primary manager is functioning properly, proceed to Step 5. If the secondary generates a “Can’t hear manager.” alarm, proceed to Step 2.

b.

The primary receives no communication from the secondary for 30 seconds and generates a “Secondary manager in slot 5 failed.” SNMP alarm. (The primary does not check for the secondary’s heartbeat.)

2.

If you receive these failure alarms on both manager modules, wait and monitor the problem for several minutes.

3.

If the problem persists for more than a minute or two, reboot the secondary manager module from the secondary’s console.

4.

If the reboot fails to correct the problem, turn power to the PortMaster 4 off and on.

5.

If the manager modules are still not communicating, reseat the secondary manager module by pulling it out and reinserting it into the slot.

See “Safety Precautions” on page 1-4 and “Grounding Wrist Strap Instructions” on page 1-4 before proceeding.

6.

If reseating the secondary manager fails to correct the problem, reseat the primary manager module.

7.

If the communication problem persists, contact Lucent NetCare technical support.

Replacing a Failed Manager Module

Redundant manager modules are shipped with ComOS 4.2 installed. When the active system manager module fails, the secondary manager takes over as the primary manager. To hot-swap the failed manager module with a new one, follow this procedure:

1.

Make sure that you have the proper hardware and software, and take the proper safety precautions.

See “Installation and Configuration Requirements” on page 1-3 for instructions.

2.

Disconnect lines to the failed manager module.

3.

Open the top and bottom tabs on the failed manager module and remove it from the slot in the PortMaster 4 chassis.

RADIUS Improvements for L2TP

2

ComOS 4.2 adds the new Layer 2 Tunneling Protocol (L2TP) set l2tp id-for-host command and the new L2TP Bearer Type attribute, and supports RADIUS enhancements for authorization, authentication, and accounting of L2TP users.

New L2TP Command

You can set an L2TP access concentrator (LAC) to use the RADIUS

Tunnel-Assignment-ID value instead of its IP address or hostname during L2TP tunnel negotiations with its peer—the L2TP network server (LNS). This attribute allows for more precise tracking of tunnel usage for accounting.

To specify whether a LAC uses the RADIUS Tunnel-Assignment-ID value or its IP address or hostname during L2TP tunnel negotiations, use the following command:

Command>

set l2tp id-for-host on | off

Setting id-for-host to on sets a LAC host to identify itself by its RADIUS

Tunnel-Assignment-ID value. Setting id-for-host to off sets a LAC host to use its hostname or IP address during tunnel negotiations. This is the default.

New L2TP Bearer Type Attribute

The Bearer Type L2TP attribute identifies the type of calling device used in an L2TP connection as analog or digital. The LAC sends this information to its L2TP peer (the

LNS). The LNS then passes the information to the RADIUS accounting server in the

NAS-Port-Type attribute.

New RADIUS Tunnel Attributes for L2TP

The RADIUS Attributes for Tunnel Protocol Support Internet-draft defines a set of RADIUS attributes to implement compulsory tunneling. To provide this functionality, ComOS 4.2 supports the following new RADIUS tunnel attributes for L2TP with Lucent RADIUS 2.1 or a RADIUS server with equivalent functionality:

• Tunnel-Client-Endpoint—this attribute contains the address of the initiating end of the L2TP tunnel (the LAC). This attribute can be used to provide a globally unique way to identify a tunnel for accounting and auditing uses.

• Tunnel-Password—this attribute supports an encrypted password between a

RADIUS server and a LAC.

• Tunnel-Assignment-ID—this attribute enables RADIUS to inform the tunnel initiator

(the LAC) about how to assign the session—to a multiplexed tunnel or to a separate tunnel.

2-1

New RADIUS Tunnel Attributes for L2TP

• Tunnel-Preference—this attribute indicates the relative preference assigned to each tunnel if more than one set of tunneling attributes is returned by the RADIUS server. For example, if two different tunnel end points are included in the RADIUS attributes, the tunnel end point with the lowest value specified in the value field is given preference.

If these attributes are not already in your RADIUS dictionary, add them as follows:

ATTRIBUTE

ATTRIBUTE

ATTRIBUTE

ATTRIBUTE

Tunnel-Client-Endpoint

Tunnel-Password

Tunnel-Assignment-ID

Tunnel-Preference

66

69

82

83 string string string integer

RADIUS Tunnel Attribute Tags

In versions of RADIUS that support this feature, you can now tag all RADIUS tunnel attributes so that ComOS can manage redundant tunnels more easily. The tag field can assign the same ID to each attribute for a particular tunnel server end point to group the attributes and identify the tunnel more clearly.

Note –

Lucent RADIUS 2.1 does not currently support the tagging feature.

Redundant Manager Module Commands

ComOS 4.2 introduces the following commands to configure and manage the redundant system manager module. ComOS 4.2 also includes existing commands that have been modified to support the redundant manager module.

Chapter 1, “Installing and Working with the Redundant Manager Module,” describes in detail how to use these commands to configure the redundant manager module for the

PortMaster 4.

3-1

Redundant Manager Module Commands

copy peer

copy peer

This command copies a file between the system manager modules.

copy /Subdirectory/Filename(source)

peer:[/Subdirectory/Filename(destination)]

/Subdirectory Path to the file.

/Filename(source) Name of the file to be copied. Filenames and directory names cannot exceed 16 characters.

peer:

Manager module to copy the file to.

/Filename

(destination)

Optional name to assign to the copied file in the new directory. If no name is specified, the PortMaster assigns the original filename.

Leave no space between peer: and the path to the file and filename.

Usage

ComOS 4.2 supports an enhanced copy command that allows a specific file to be copied from one manager module to another manager module using the peer keyword.

Each manager module has is own file system. Use the show files command before and after using the copy command. See the copy command description in the PortMaster 4

Command Line Reference for additional information.

Example

Command> copy /shared/m2c_2.4 peer:

Queued transfer of /shared/m2c_2.4 to /shared/m2c_2.4 on peer.

Usage

ComOS 4.2 supports the enhanced show bootlog command, which now displays register and software version information in the output.

Use this command to capture reboot information without using a console. The

PortMaster 4 reserves a portion of its memory to store stack traces and the last process ID. The boot log is stored in the nonvolatile RAM file system in a file named

bootlog, a circular buffer up to 64KB in length.

3-6 PortMaster 4 User Manual Addendum

Redundant Manager Module Commands

show smm-backup

When a board in the PortMaster 4 reboots, it checks for information in the reserved area and sends it to the boot log and the console, if configured. This portion of memory is not overwritten at boot time so this information can be preserved. To erase boot log information, use the erase file bootlog command.

To translate the last process and stack trace data, send the information to Lucent Netcare

Technical support.

The information that is stored in the boot log consists of the following:

Time Stamp

RADIUS Commands

ComOS 4.2 introduces the following RADIUS commands to configure the PortMaster 4 to use a RADIUS server. For a complete list of RADIUS commands, see Chapter 3 of the

PortMaster 4 Command Line Reference.

set accounting count

This command sets the number of times the PortMaster attempts to send a RADIUS accounting packet to a RADIUS accounting server.

3-8 PortMaster 4 User Manual Addendum

RADIUS Commands

set accounting interval

set accounting count Number

Number

Number of times the PortMaster attempts to send a RADIUS accounting packet to a RADIUS accounting server if it does not receive an acknowledgment from the server.

Integer between 1 and 99. The default is 5.

Usage

When the PortMaster attempts to send a RADIUS accounting packet to the RADIUS accounting server and it does not receive an acknowledgment, it retransmits the packet the number of times set with this command.

If no acknowledgment is sent from the primary accounting server in response to the last retry packet, the PortMaster sends the packet to both the primary and alternate RADIUS accounting servers.

If an acknowledgment is received from the RADIUS accounting server, the PortMaster no longer tries to resend the accounting packet.

To view the accounting count setting, use the show global command.

Example

Command> set accounting count 45

Accounting retry count changed from 23 to 45

See Also

set accounting interval

- page 3-9

set accounting interval

This command sets the interval between accounting packet retransmissions to a RADIUS accounting server.

set accounting interval Seconds

Seconds

Number of seconds that elapse between RADIUS accounting packet retransmissions that are not acknowledged by an accounting server.

Integer between 1 and 255. The default is 30 seconds.

ComOS 4.2 Commands 3-9

RADIUS Commands

set authentication failover

Usage

When the PortMaster attempts to send a RADIUS accounting packet to the RADIUS accounting server and it does not receive an acknowledgment, it retransmits the packet the number of times set with the set accounting count command. Use the set

accounting interval command to set the time interval between attempts to resend the

RADIUS accounting packet.

If no acknowledgment is sent from the primary accounting server in response to the last retry packet, the PortMaster sends the packet to both the primary and alternate RADIUS accounting servers.

To view the accounting count and the accounting interval settings, use the show global command.

Example

Command> set accounting interval 60

Accounting retry interval changed from 30 to 60 sec

See Also

set accounting count

- page 3-8

set authentication failover

This command enables the PortMaster to dynamically switch primary and alternate

RADIUS authentication servers based on their response to authentication requests.

set authentication failover on|off

on off

If the primary authentication server fails to respond to three consecutive requests, the PortMaster sends seven requests to both the primary and secondary servers.

If the secondary server replies before the primary server, it becomes the primary server.

The PortMaster always tries the primary server first. This is the default.

Usage

This command enables the RADIUS authentication failover feature on the PortMaster.

When RADIUS authentication failover is enabled, the PortMaster does the following:

1.

Sends three access-request packets to the primary authentication server and awaits a response.

3-10 PortMaster 4 User Manual Addendum

RADIUS Commands

set authentication interval

2.

Sends seven requests to both the primary and secondary authentication servers and awaits a response.

3.

If the secondary server responds first and failover is set to on, designates it as the primary authentication server and sends it the authentication request from the next login attempt.

4.

If the designated primary server does not respond after three attempts, starts the failover process again.

The server currently designated as primary is marked with an asterisk (*) in the output of the show global command.

To set the request interval, use the set authentication interval command.

Example

Command> set authentication failover off

Auth failover changed from on to off

See Also

set authentication interval

- page 3-9

set authentication interval

This command sets the number of seconds that a PortMaster waits for a response from a

RADIUS authentication server.

set authentication interval Seconds

Seconds

Value between 1 and 255. The number of seconds that must elapse between RADIUS access-request retransmissions if the

PortMaster receives no response from a RADIUS authentication server. The default is 3 seconds, and 0 resets the value to the default.

Usage

The Seconds value determines how long the PortMaster waits before sending a subsequent request to the authentication server. In addition, the PortMaster waits two times this value to initiate failover. For example, if set authentication interval 6 is used, failover occurs in 12 seconds.

Example

Command> set authentication interval 15

Auth retry interval changed from 5 to 15 sec

ComOS 4.2 Commands 3-11

L2TP Command

set l2tp id-for-host

Second alternate gateway.

Third alternate gateway.

IP address of the alternate gateway.

Usage

To use this command, you must first select a slot for configuration using the set view command.

Use this command to configure the alternate gateways for each card. To remove an alternate gateway, set the IP address to 0.0.0.0.

Each slot card first attempts to connect to the primary gateway. If the attempt is unsuccessful, the card retries in the following order:

1.

First alternate gateway

2.

Second alternate gateway

3.

Third alternate gateway

4.

Primary gateway

Only one SS7 gateway must be active at any given time. When an alternate gateway is enabled after a line board detects that the primary gateway is unavailable, a failover is accomplished within 30 seconds or less. The PortMaster 4 retains calls between failovers, and informs the new gateway about existing calls.

3-14 PortMaster 4 User Manual Addendum

SS7 Commands

set imt-alt

Note – If multiple gateways are running at the same time, a situation can occur in which the first connection attempt might succeed for an alternate gateway, and the different slots become connected to different gateways. When the primary gateway comes back online, the alternate gateways must be shut down to allow the PortMaster 4 to switch back to the primary gateway.
