Introduction 9

RMON Probe Capability

The Remote Network Monitoring (RMON) probe is an instrument that exists for the purpose of managing a network. The goals of the RMON probe are described in the following sections: Offline Operation, Proactive Monitoring, Problem Detection and Reporting, Value Added Data, and Multiple Managers. The CenturyStack 8100 Managed Series Hubs support RMON group (1) statistics, group (2) History, group (3) Alarm, and group (9) Event.

• Offline Operation: This allows a probe to be configured to perform diagnostics and to collect statistics continuously, even when communications with the management station may not be possible or efficient.

• Proactive Monitoring: The monitor can notify the management station of failure and can store historical statistical information about the failure. The management station can play this historical information back in an attempt to perform further diagnosis into the cause of the problem.

• Problem Detection and Reporting: The monitor can be configured to recognize conditions, most notably error conditions, and to continuously check for them. When one of these conditions occurs, the event may be logged, and management stations may be notified in a number of ways.

• Value Added Data: By highlighting those hosts on the network that generate the most traffic or errors, the probe can give the management station precisely the information it needs to solve a class of problems.

• Multiple Managers: Remote monitoring can deal with multiple management stations using its resources concurrently.

10 CenturyStack

®


Redundant Link Capacity

Redundant links can be configured enabling up to 24 pairs in a

CenturyStack. For each pair of redundant links one port must be set as the primary and active, the other as backup and isolated. If the primary port fails, it is isolated and the backup port is set to primary and active.

Address Tracking Capability

CenturyStack provides MAC Address based tracking capability for traffic analysis to diagnose network problems such as Intrusion. This function records the source MAC address of each data packet received by the port and provides the filter for data analysis. Up to 15 source MAC addresses can be detected on each port.

Source Address Search Capability

CenturyStack provides Source Address Search Capability. This active address tracking capability is used to watch for a given MAC address and report on which port it was seen. This capability can be used to collect the necessary information for mapping the topology of a network. Up to 8

MAC addresses can be searched simultaneously. You can configure address search parameters including Source MAC address and Address

Search Status with local console management, Web-Based Management or SNMP management.

Security Intrusion Control Capability

CenturyStack provides MAC Address based Security Intrusion Control

Capability to prevent any unauthorized nodes access to the network. You can configure the hub to take various actions when a violation is detected.

Actions include: no action, sending a trap message or partitioning a port.

Broadcast Storm Detection and Protection Capability

CenturyStack provides Broadcast Storm Detection and Protection

Capability by periodically monitoring the broadcast counters of each port to detect a broadcast storm. Ports detected causing a broadcast storm are automatically partitioned, a trap is sent to the network manager, or no action is taken, depending on the configuration.

Chapter 1

Installation

Choosing a Location

The CenturyStack location should be less than 100 meters from servers, workstations, or switches. The CenturyStack can be desk mounted or rack mounted.

CAUTION: Category 5 UTP/STP cables are environmentally sensitive. Make sure that the cable route is not too close to electrical noise sources such as power lines or fluorescent lights.

Stacking

The CenturyStack Managed Series are stackable in standard 19” racks.

Up to six hubs can be stacked with cascade cables. One master and up to five slaves can make up a stack. The master can be positioned anywhere in the stack, so you can add to a stack without re-positioning the hubs.

Rack Mounting

Rack mounting brackets are included to mount hubs in a standard EIA

19-inch racks.

Align the mounting brackets on the sides of the unit with the slit over the holes. Secure the screws tightly to fix the brackets to the device. Then, place the device into the 19" rack and affix it properly. Please ensure that the ventilation holes on the unit are not blocked.

Using Cascade Cables

You can stack the CenturyStack 8100 Series hubs using cascade cables.

The master hub can be placed anywhere in the stack. By cascading the hub stack, each hub is automatically identified and assigned an ID number according to its position in the stack.

Installation 17

Cascading hubs with cascade cables to make a stack is as simple as connecting the Up port of one hub to the Down port of another hub as illustrated below.

Constructing a Management Hub Stack

A stack can be constructed with up to six hubs in total. One master hub and up to five slave hubs can exist in one stack.

Position within the Stack

The master hub can be positioned anywhere in a stack and automatically assigns the ID of each hub according to its position in the stack.

Master Hub Role

The master is used to manage and configure other hubs in the stack and supplies the stack with additional ports (12/24) and an additional expansion module slot. The master hub can also be used as a stand-alone intelligent hub. Managing the hubs can be accomplished with the master hub’s versatile management capabilities, such as:

•

SNMP Management

Refer to the CenturyStack Network Management Guide

Slave Hub Role

Slave hubs supply the stack with additional ports (12/24) and an additional expansion module slot. Slave hubs can be positioned above or below the master hub. The 8112-01-S and 8124-01-S can also act as stand alone unmanaged hubs.

Hub ID

The master hub and slave hubs can be positioned anywhere in the stack and each hub’s ID is automatically assigned based on its position (in the stack).

Segmenting Hubs

CenturyStack hubs can isolate one or both segments (10 Mbps and 100

Mbps segments) from the other hubs in a stack. When a segment is isolated it does not repeat to the other segments in the hub or to other segments in the stack.

Connecting Devices

The dual speed CenturyStack can connect to 10Mbps, 100Mbps, or

10/100Mbps devices due to its auto sensing capability. CenturyStack will auto sense the connected port speed and set its port to match the speed of the connected port.

Cables

CenturyStack ports accept Cat 3, 4 and 5 cables with RJ-45 connectors for 10Mbps connections and Cat 5 cables with RJ-45 connectors for

100Mbps connections. The maximum length of cables, between hub and workstations is 100 meters. The maximum length of cables, between hub and hub is 5 meters for 100Mbps connections and 100 meters for

Using Expansion Modules

Expansion Module Overview

Expansion modules provide additional functions such as internal bridging of 10Mbps and 100Mbps segments and extended distances between devices. The available modules are:

• Module 8102-01-X: 2 port Bridge or 10/100BASE-TX

Switch Module

• Module 8102-03-X: 2 port Bridge or 100BASE-FX

Fiber Distance Extender Switch Module

• Module 8103-01-X: 3 port Bridge and 10/100BASE-TX

Switch Module

• Module 8103-03-X: 2 port Bridge and 100BASE-FX

Fiber Distance Extender Switch Module

With CenturyStack, the software setting for Bridging Module Admin State

(external distance extender function and internal function) is disabled by default. The Admin State of a bridge module must be configured using

Console or Web-Based Management after installation.

Internal Bridge Function

The Internal Bridge Function is used for bridging 10Mbps and 100Mbps segments in a hub or in a stack. Only one internal switch can be enabled in a CenturyStack, more than one will cause network looping.

IMPORTANT: There can only be one internal switch enabled in a

CenturyStack, however multiple external bridges are allowed. Therefore, if more than one module exists in a CenturyStack, ensure that only one module has its internal bridge enabled.

External Bridge Function

The external bridge function is used to extend the distance between

100Mbps hubs or stacks from the normal limitation of five meters to one hundred meters with TX modules using RJ 45 cable. With FX modules using fiber cable, you can expand the distance between hubs or stacks up to 2km.

Using Expansion Modules 23

Backpressure (flow control)

When packets are passed from 100Mbps segments to 10Mbps segments the flow is restricted due to the lesser capacity of the 10Mbps segment causing backpressure and resulting in dropped packets. With flow control or backpressure enabled, packets are made to wait until the flow is unrestricted before being sent, reducing the number of dropped packets.

Installing a Bridge Module

Power down CenturyStack before installing a bridge module. Bridge modules have both hardware and software configuration settings. The hardware configurations must be made before you physically install the module and the software configurations must be made using a master hub, after the module is installed and before the bridging functions take effect.

Please read this section carefully before installing modules.

IMPORTANT:

• These modules are not hot swappable. You must remove power from the hub before installing or replacing a bridge module.

• You should enable the internal bridge on only one bridge module when you have multiple bridge modules installed in a CenturyStack. This prevents a network loop condition.

• Three bridge modules are shipped with the Internal

Bridge function enabled (8102-01-X, 8103-01-X and

8103-03-X), only the 8102-03-X is shipped with the

Internal Bridge function disabled. All models ship with the backpressure function disabled.

To install these modules, perform the following steps. Use static sensitive precautions.

1. Set the bridge function and backpressure function by moving the appropriate jumpers. See the following sections for the bridge module model that you are installing and set the jumpers accordingly.


2. Remove the power from the hub by disconnecting the power cable from the AC outlet.

3. Remove the installed bridge module or blank cover of the expansion module slot (not the NMU slot, only the bottom slot is available) by turning the two knobs on the front counterclockwise as shown below.

5. Turn the two knobs on the new bridge module until they are securely attached to the hub.

6. Connect the appropriate communication cable to the new module.

7. For stand alone slave models the installation is complete, just connect AC power.

8. If your adding this hub to an existing stack, connect the hub to the stack. Refer to Chapter 1: Using Cascade Cables.

9. Reconnect the AC power cord to the wall outlet.


10. For a hub stack with a master present, you must configure the software for the installed bridge module to enable the internal bridge function because the software default setting is disabled. The default software setting will not allow the internal bridge function to enable. The software must be configured using a master hub.

11. Start a Console or Web-Based Management session and set the software configuration for the new module. For information on starting a console session, refer to

Chapter 4: Console Management. For information on

Bridge Module configuration, refer to Chapter 4: Console

Management: Controlling Devices.

Observing Network Traffic

You can observe the network traffic in the Mini Console with the Utilization menu. Seven columns of gauge bars, which shift continuously from left to right as time elapses, represent the utilization rate of each segment.

The gauge bar columns on the left are for the 10Mbps segment and the gauge bars on the right are for the 100Mbps segment. Each column of gauge bars is a historical view of the total utilization in the 10Mbps segment and the total utilization in the 100Mbps segment at the time the statistics were taken by the hub. The total utilization history, represented by the seven columns in each segment is over a three-second time frame.

Network Configuration

There are several ways or Network Interfaces that you can use to configure the hub. You must set up the hub using Local Console management to enable the other management capabilities:

• Mini Console (see Chapter 3)

• Local Console/Remote Telnet

• Web-Based Management

• SNMP Management

The Network Configuration Menu allows setting up Ethernet and SLIP connections to the hub. Network Interface <1> is used to configure

Ethernet connections and Network Interface <2> is used to configure

SLIP connections.

Local Console/Remote Telnet-Ethernet

An Ethernet connection allows you to monitor and configure the hub with a Local Console via Telnet Session, a Web browser or SNMP management. You need to configure the IP Address and Subnet Mask to work with your LAN settings before you can make an Ethernet connection.

In-Band Ethernet Configuration Menu


Interface: The current interface number; 1=Ethernet, 2=SLIP

Interface T ype: The interface type — Ethernet or SLIP

MAC Address: Displays the hub’s MAC Address, for example:

00-E0-95-00-00-05.

IP Address: The dotted decimal address assigned to the

CenturyStack.

Subnet Mask: The dotted decimal subnet mask assigned to the

CenturyStack.

Default Gateway: The dotted decimal IP address of the default gateway assigned to CenturyStack. CenturyStack must be restarted before the IP address, subnet mask, and default gateway can take effect. To ensure that the new information is correct, a “ping” should be done from another device connected to the CenturyStack.

NOTE: The hub does not respond to ping packages that are greater than 1484 bytes.

Local Console/Remote Telnet-SLIP

SLIP connections enable monitoring and configuring the CenturyStack remotely with a modem. To make SLIP connections use Network

Interface <2> and set the configurations shown below.

NOTE: The SNMP agent, TCP/IP stack and the Web engine are implemented on the 10Mbps bus of the master hub. Therefore the 10Mbps segment must be used for Web-Based Management in the absence of a switch module.


Out-of-Band Serial Configuration Menu

The baud rate, character size, parity, and stop bits are read only and not configurable.

Baud Rate: The current serial port baud rate that can be configured from the Serial Port Configuration Menu.

Character Size: 8 bits character size

Parity: None

Stop Bits: 1 stop bit

IP Address: The dotted decimal address assigned to the SLIP interface of CenturyStack

Subnet Mask: The dotted decimal mask assigned to the SLIP interface of CenturyStack.


Serial Port Configuration

The Serial Port Configuration Menu is used to configure Console Mode connections to a VT-100 terminal emulator and Out-of-Band serial connections to a modem.

Console Mode

To view the Console Mode settings, select “Console” Mode in the Serial

Port Configurations. Console Mode settings are read only. Use the settings as shown below.

Console Operation Mode

Out-of-Band Mode

Out-of-Band mode enables setting up serial port configurations for making a connection to the hub using a modem.

To make Out-of-Band serial connections use the Out-of-Band operation mode in the Serial Port Configurations Menu shown on the next page.


Out-of-Band Operation Mode

Baud Rate: The baud rate can be configured as one from

2400bps, 4800bps, 9600bps, 19200bps. The default is 9600.

Character Size: 8 bits character size

Parity: No parity.

Stop Bits: 1 stop bit

Select <Save> to retain the new configuration. The new configuration takes effect if Out-of-Band management is enabled.

When SLIP is enabled, the EIA 232 port can be used for SLIP only. The

EIA 232 port cannot be used to gain access to a management session via

VT100 terminal emulation. If the SLIP connection is malfunctioning, you can disable SLIP by rebooting and pressing <Enter> when the Abort message appears. The message will appear for only 10 seconds. OOB also appears on the lower right side of the Mini Console. You can also establish a Telenet session and modify the serial port configuration.


SNMP Community Setup

The SNMP Community Setup Menu is used to set up SNMP communities. Up to six Community Names, Access Rights, and Status can be configured.

You can add, delete, or edit SNMP community names, set the access rights and status. Community names are case sensitive, Private and private are considered different. You cannot enter the same name more than once; an error message appears at the bottom of the panel. Press the

Redundant Link Control

The Redundant Link Control menu allows configuring up to 24 pairs of redundant links. A redundant pair consists of any two physically linked ports in the stack, where one is the primary link port and the other is the secondary link port. The primary link is the active link between two devices and the secondary is a backup and is set to inactive to prevent looping. In the event that the primary link fails, the secondary link becomes active. The secondary link stays active even if the primary link recovers. You must manually reset the primary link status to active in order to re-instate the redundant pair.

Redundant Link Control

You configure a primary link by assigning a specific port on a specific hub to a Link Pair Index. You assign a secondary link by assigning a specific port on a specific hub to the same Link Pair Index.

Link Pair Index: The number identifying the redundant link pair. (1 to 24)

Secondary Link Port:

This object identifies the port number of the secondary link for a given redundant link pair.

Active Link: This object indicates the current status for a given redundant link pair.

• Primary: The port is currently the active primary link.

• Secondary: The port is currently the secondary port.

• Both fail: Both the primary and the secondary failed.

Link Switch Over Notify:

If the link status of the active link is down for more than five seconds then the active link failure is detected and “port switch over” is performed and a trap is sent to the trap receivers.

• Enable: A trap is sent to the trap receivers if a switch over occurs.

• Disable: No trap is sent to the trap receivers if a switch over occurs.

Status: You can enable, disable or suspend the operation of specific redundant link pairs.

• Enable: The redundant link pair is in the normal operation mode.The primary port is active and the secondary port is disabled.

• Disable: If you disable the active port, the status of this link pair is changed to the suspend state and indicates that the active port has been disabled and the redundant link function is temporarily suspended. If you enable the active port later on, the status of this redundant link pair is changed to enabled.

NOTE: Setting the redundant link to disable does not cause the ports to be switched over.


• Suspend: Indicates that the active ports are disabled and the redundant link function is temporarily suspended until you set its state to enable.

NOTE: The suspend state does not cause the port to be switched over.

• Invalid: Purge the configuration of a redundant link pair from the system database.

• Return-to-primary: Selecting this option and pressing enter re-assigns the primary link as the active link again. A trap is sent to the trap receivers if the status of the redundant link is enable. If the status is suspend, then the link pair is reactivated, but no trap is sent.

2. Perform a cold restart on the system.

You should perform a code download only to update existing software or if existing code has become corrupted.

Before performing a system download, make sure that you know the IP address of your TFTP server and the location of the files on the server.

NOTE: Use the following naming convention:

• Boot ROM Code download - 110Vxxx.BT

• Web Pages Database Information Download –

110Vxxx.WEB

• System Software Download - 110Vxxx.RT

where, xxx is the version number.

To download TFTP code, perform the following:

1. Enter the IP address of the TFTP server.

2. Select the downloads that you want to perform.

3. Enter the path and file name for each of the downloads you have selected (for example, C:\microcode\110V101.BT).

4. Save the configuration.

5. Restart the system.

System Restart

The System Reset Menu allows the user to reset the system with a Cold or Warm reset.


System Restart Menu

You can restart the system at any time without losing configuration settings, except in the case of a download. When you select Execute and then select <Enter>, a warning message informs the user that system restart is going to be performed right now.

Warm: A warm restart restarts the hub at the runtime code.

For most cases, a warm restart is sufficient, except in the case of a BootP request or code download.

Cold: A cold restart restarts the hub at the BOOTROM level and is the same as unplugging and re-plugging power to the hub. A cold restart is needed when the user performs a BootP request or code download.


Factory Reset

The Factory Reset Menu allows resetting CenturyStack to the original factory settings. All user configurations will be lost. A Confirm Messages displays before the hub is reset so the user can abort the factory reset.

Factory Reset Menu

The Factory Reset Menu lets you return all Hub settings to the original default settings.

When you issue a factory reset, all of your custom settings are overwritten.

To perform the factory reset, do the following steps:

1. Select how the user wants network configuration processed during a factory reset:

• Not Reset: Current configuration is saved.

•

Reset from BootP:

Request a new network configuration from the BootP server.

•

Reset to factory default:

Current network configuration is reset to factory defaults.


2. Select how the user wants the user authentication configuration processed during a factory reset:

• Not Reset: Current user authentication configuration is saved.

•

Reset to factory default:

Current user authentication configuration returns to factory defaults.

3. Select Execute and press <Enter>.

When Execute and Enter are selected, a warning message informs the user that system configuration data will be reset.

Login Timeout Interval

Login Timeout Interval Menu

This menu lets you select the time after which an established Telnet session is automatically logged out if inactive. The range is zero to 60 minutes. The default is five minutes. If you specify zero, the session remains logged in regardless of how long it is inactive.


Configuration Upload Setting

CenturyStack network management provides the capability to upload the hub configuration data to the remote server in binary format. You can upload your configuration files and save as a backup in case you need to restore your system settings.

Configuration Upload Setting Menu

Enter the TFTP Server IP Address and the chosen file name (for example: filename.CFG) and the path where the files will be uploaded on the server. Select Save to save your configuration settings, and then request the upload using the Configuration Upload Request Menu.

TFTP Server IP Address: The IP address of the server where the configuration files are to be stored.

Configuration File Name:

The name of the configuration file and the full path.


Configuration Upload Request/Status

Configuration Upload Request

This menu enables you to submit a request for a configuration file upload and view the status of a download. Select Submit to make the Upload

Request.

TFTP Server IP Address: The IP address of the server where the configuration files will be uploaded.

Configuration File Name:

The name of the configuration file and the full path.

Troubleshooting the Network

Q: The local-console ‘login screen’ does not come up sometimes when a terminal (PC running terminal emulation) is connected to already booted master hub. Why?

A: The screen must be refreshed, when CenturyStack is running and the terminal emulator is started. Pressing Ctrl + R refreshes the screen and the login menu appears.

Q: Users of the 100Mbps segment cannot use Web-Based Management, however 10Mbps segment users can. Why?

A: The SNMP agent, TCP/IP stack and the Web engine are implemented on the 10Mbps bus of the master hub. Therefore the 10Mbps segment must be used for Web-Based Management in the absence of a switch module.

Q: Even though the switch module with internal bridging has been installed, the 10Mbps segments can’t communicate with the

100Mbps segments. Why?

A: The switching function is disabled by default in the software, therefore even though the internal function is enabled with the on board jumpers, 10Mbps and 100Mbps segments cannot communicate. The internal switch must be enabled using local console management through connections from the RS-232 port on the hub to a serial port on a PC. Select Device Control from the main menu and then 2/3 port bridge module control/status. Enable the internal switch.

Q: With regards to CenturyStack modules: Users will need to use Web or Console management to enable the module, however, what if users only have a slave model in their LAN and want to install a 8102-01 as an internal switch or have a 8103-01 as both internal and external, or have another slave model in the stack and one 8102-01 as an external switching port?

A: In the case of 8112-01-S only, (whether single or multiple stacked), the switch module will function straightaway when installed. The mode (“internal” or/and “external”) can be set on the module PCB using the jumpers provided. When the master hub is present, we need to additionally enable the module’s function in the management software (through Local Console or Web-Based Management/SNMP

Management).


Q: Is there a loop detection and isolation feature available in

CenturyStack, in case two switch modules (internal bridging enabled on the hardware) are installed in the same stack?

A: No. The stack will go into a loop even before the software has booted.

Therefore, the only control is on hardware (jumpers on the PC board)

Q: In Web-Based Management, the Hub’s front panel is not displayed.

A: For Netscape users, you need to clear the memory cache. To clear memory cache, from the Netscape menu bar, select Edit, select

Preferences from the drop down list, click the + sign beside Advanced and then select Clear Memory Cache.

Q: I do not see the graphic of the unit when I use Internet Explorer as my browser.

A: If you are using Internet Explorer version 4.72 or newer, you will need to modify the Java settings. From the task bar, select View, then Internet Options, then Security. Set security to Custom, then go into Settings. From here, scroll down to Java and click Custom. A

Java Custom Settings box displays in the lower left corner. Select this box, highlight Permission Given to Unsigned Content, then select the

Edit Permission tab. Finally, select Enable under Run Unsigned

Content.
