Introduction

This chapter introduces the 6H203-24 and 6H253-13 SmartSwitch 6000 interface modules and provides information about how to obtain additional support from Cabletron Systems.

Important Notice

Depending on the firmware version used in the SmartSwitches, some features described in this document may not be supported. Refer to the Release Notes shipped with the device to determine which features are supported.

1.1

OVERVIEW

The SmartSwitches shown in Figure 1-1

are Ethernet/Fast Ethernet interface modules for the

Cabletron Systems 6C105 chassis. The 6H203-24 has two RJ21 champ connectors, for a total of

24 switched ports. The 6H253-13 has one RJ21 champ connector, for a total of 12 switched ports and 1 slot for an optional High Speed Interface Module (HSIM) or Very High Speed Interface

Module (VHSIM).

The SmartSwitch can be used to connect individual high-bandwidth user devices, such as workstations, or to provide a central switching point for multiple 10/100 Mbps Fast Ethernet segments. The optional HSIMs provide one or more high speed uplinks to networking technologies such as Gigabit Ethernet, Fast Ethernet, Fiber Distributed Data Interface (FDDI),

Wide Area Network (WAN) and Asynchronous Transfer Mode (ATM). Some HSIMs can also provide additional Fast Ethernet ports in varying media types. The optional VHSIMs provide very high speed uplinks to networking technologies such as ATM and Gigabit Ethernet.

The SmartSwitch ports can be configured to control frame traffic several ways, including prioritizing traffic flow according to protocol type. The SmartSwitches can also be configured to establish Virtual Local Area Networks (VLANs) and control the flow of frames associated with each VLAN according to priority and Ether type. Detailed information about VLANs is provided in the Local Management User’s Guide for this module.

Introduction 1-1

Overview

1-2 Introduction

Figure 1-1 The 6H203-24 and 6H253-13 SmartSwitches

Overview

When the modules are connected to the network and powered up, Runtime IP Address Discovery

(RAD) checks the modules for an IP address. If one has not yet been assigned (module and 6C105 chassis IP address set to 0.0.0.0), RAD checks to see if any of the module interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an

IP address from a RARP or BootP server on the network.

The RAD requests start at an interval of one per second. The interval then doubles after every transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300 seconds. The RAD requests continue until an IP address is received from a RARP or BootP server, or an IP address is entered using Local Management.

The module will reboot after RAD is successful.

NOTE

1.1.4

Full Duplex Switched Ethernet

Each switched Fast Ethernet port on the SmartSwitches supports 10/100 Mbps operation and can be configured to operate in Full Duplex Switched Ethernet (FDSE) mode. FDSE allows each port to provide up to 200 Mbps of bandwidth.

1.1.5

SmartTrunk

SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’ terminology for load balancing or load sharing. SmartTrunk technology provides an easy-to-implement mechanism to group, or aggregate, multiple links of any technology together to scale the backbone bandwidth beyond the limitations of a single link. All links are user-configurable so administrators can scale the backbone bandwidth by adding SmartTrunk links.

The benefits of SmartTrunking include the following:

• All purchased bandwidth is used.

• Distributed, resilient links increase reliability and performance.

• Multiple technologies are supported within a single trunk for maximum flexibility.

NOTE

For information on SmartTrunk configuration, refer to the Cabletron Systems

SmartTrunk User’s Guide .

1-4 Introduction

Overview

1.1.6

Remote Monitoring (RMON)

The SmartSwitches support all nine Ethernet RMON groups. The Statistics, Alarms, Events and

History groups are enabled on all ports by default.

Cabletron Systems RMON Actions is a vendor-specific extension of RMON and provides the ability to set an “Action” on any SNMP MIB variable. The Action can be triggered by setting an

RMON Event and/or Alarm. An example of an Action would be to turn off a MIB-2 interface if a broadcast threshold is crossed.

1.1.7

Broadcast Suppression

Broadcast Suppression enables a user to set a desired limit of receive broadcast frames per port/per second to be forwarded out the other ports on the module up to the set limit. Any broadcast frames above this specified limit are dropped. In the event that broadcast frames are being suppressed, multicast and unicast frames continue to be switched.

1.1.8

Port/VLAN Redirect Functions

The port redirect function, also referred to as “Port Mirroring,” is a troubleshooting tool used to map traffic from a single source port to a single destination port within the device. The feature allows frames, including those with errors, to be copied and sent to an analyzer or RMON probe.

The analyzer or RMON probe will see the data as if it were directly connected to the LAN segment of the source port.

The VLAN redirect function is similar to the port redirect function except that the frames received by the device are redirected to a designated destination port according to the VLAN classification of the frames received. The VLAN redirect function does not support redirecting errors, and is only supported when the device is operating as an 802.1Q switch. Multiple VLANs can be directed to the same ports.

1.1.9

Rate Limiting

The Rate Limiting feature enables the SmartSwitch device to have control of traffic rates on a per-port, per-priority basis. The network administrator can configure a rate limit (from 100 kbps to

1 Gbps) for a given port with an associated list of IEEE 802.1p priorities (which can include one, some, or all of the eight priority levels defined in 802.1p). Each rate limit is specified as an inbound or an outbound limit. The combined rate of all traffic on the port that matches the listed priorities cannot exceed the programmed limit. If the rate exceeds the defined limit, frames are dropped until the rate falls below the limit.


Overview

Administrators can configure up to four rate limit rules per port; however, each rule must not include conflicting 802.1p priority values. In order to control traffic inbound and outbound on the same port, two rate limit rules must be configured (one inbound and one outbound). Since the rate limiting operation occurs after the processing of the multi-layer classification rules, the two features can be combined to provide application-aware rate limiting.

This traffic rate function is not supported on ports configured as SmartTrunk ports.

NOTE

For more information about the application of the Rate Limiting function, refer to the SmartSwitch

Series 6H202, 6H203, 6H252, 6H253, 6H258, 6H259, 6H262, 6E233, and 6E253 Local

Management User’s Guide.

1.1.10 GARP Switch Operation

Some or all ports on the switch may be activated to operate under the Generic Attribute

Registration Protocol (GARP) applications, GARP VLAN Registration Protocol (GVRP) and/or

GARP Multicast Registration Protocol (GMRP).

GARP is a protocol, or set of rules, that outlines a mechanism for propagating the port state and/or user information throughout a bridged LAN to keep track of users and VLANs on the network fabric. MAC bridges and end users alike can take part in the registration and de-registration of

GARP attributes such as VLAN and multicast group membership. For more details on how GVRP and GMRP handle frames under GARP, and how to configure the switch ports to take advantage of this operation, refer to the SmartSwitch Series 6H202, 6H203, 6H252, 6H253, 6H258, 6H259,

6H262, 6E233, and 6E253 Local Management User’s Guide.

1.1.11 Flow Control

Flow Control is a method of managing the flow of frames between two devices. It ensures that a transmitting device does not overwhelm a receiving device with data. This enables the receiving device to communicate with the transmitting device, and to have it pause its transmission while the receiving device processes the frames already received. Both devices must support the

IEEE 802.3x standard for flow control to work.

The SmartSwitches support the following two types of flow control:

• frame based 802.3x

• back pressure

1-6 Introduction

Overview

Frame based 802.3x flow control is supported on all Ethernet ports operating in the full duplex mode. Flow control can be enabled or disabled on a port-by-port basis.

Back pressure flow control is supported on all Ethernet ports operating in the standard mode of operation. Flow control can be enabled or disabled on a port-by-port basis.

1.1.12 802.1 Port Priority

IEEE 802.1 port priority is incorporated in the IEEE 802.1D standard. It is used to assign a default priority to the frames received without priority information in their tag header, to map prioritized frames to the appropriate transmit queues, and to prioritize frames according to protocol type.

1.1.13 Management

Management of the SmartSwitch modules and 6C105 chassis is accomplished using the Local

Management application or remote SNMP management stations. Local Management is accessible through the RS232 COM port on the front panel using a local VT100 terminal, or a remote VT100 terminal via a modem connection, and in-band via a Telnet connection. In-band remote management is possible through any SNMP compliant Network Management Software.

Local Management, as described in your Local Management User’s Guide, provides the ability to manage the SmartSwitches and offers information for Ethernet HSIMs or VHSIMs. Local

Management information for non-Ethernet HSIMs or VHSIMs is included in their respective user’s guide. For details on how to get manuals, refer to the Related Manuals section in the About

This Guide section.

Services between all of the front panel interfaces including any optional HSIM and VHSIMs. In the 802.1Q mode (the default mode of operation), the switch functions as an 802.1D switch until

802.1Q VLANs are configured.

SecureFast switching and IEEE 802.1Q switching allow migration to Virtual Network technologies without requiring the replacement of existing equipment.


Overview

1.1.15 Distributed Chassis Management

From a management perspective, the 6C105 SmartSwitch 6000 chassis can be viewed as a single entity with a single IP address. Its systems management functions are distributed to all modules.

The chassis can be managed using a single IP address, or the modules can be managed separately by individual IP addresses. When using a single IP address, system wide settings can be done from the chassis menu in Local Management, while module settings are done by selecting the specific module to be modified and changing the settings for that module.

1.1.16 Optional HSIMs and VHSIMs

The 6H253-13 provides a slot for an optional High Speed Interface Module (HSIM) or Very High

Speed Interface Module (VHSIM) for additional connectivity to various networking technologies.

Any exceptions to the HSIMs and VHSIMs that operate in the 6H253-13 are listed in the Release

Notes shipped with the 6H253-13.

1.1.17 Standards Compatibility

The SmartSwitches are fully compliant with the IEEE 802.3, 802.3x, 802.3u, 802.1D, and especially 802.1Q standards. The SmartSwitches provide IEEE 802.1D Spanning Tree Algorithm

(STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The SmartSwitches support a wide variety of industry standard MIBs including

RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1493 (Bridge MIB), RFC 1354 (FIB MIB), and

RFC 1190 (Path MTU Discovery). A full suite of Cabletron Systems Enterprise MIBs provide a wide array of statistical information to enhance troubleshooting.

Flashing indicates an irregular LED pulse.

Blinking indicates a steady LED pulse, (approximately 50% on, 50% off).

Solid indicates a steady LED light. No pulsing.

4.1.1

The LED Mode Switch

The SmartSwitches have an LED mode switch, located on the front panel, that allows the user to

change the function of the LEDs. Refer to Figure 4-1

for the location of the LED mode switch.

When the switch is in the UP position, the LEDs indicate the receive (RX) and transmit (TX) status of the fixed ports. When the mode switch is in the DOWN position, the LEDs indicate at what speed the applicable port is currently operating (10 Mbps or 100 Mbps) and if the applicable port is operating in standard or full duplex mode.

Troubleshooting 4-1

Using LANVIEW

NOTE

The LED mode switch does not change the function of any LEDs on an HSIM or VHSIM installed in the 6H253-13.

Switch Settings, Upgrades, and Installations

This appendix covers the following items:

• Setting the mode switches (

Section B.1

)

• Installing the DRAM SIMM (

Section B.2

)

• Location for installing HSIMs or VHSIMs (

Section B.3

)

!

CAUTION

You need an antistatic wrist strap (provided with 6C105 chassis) to perform the procedures in this appendix. Use the antistatic wrist strap when performing any of the procedures in this appendix to minimize ESD damage to the devices involved.

B.1

SETTING THE MODE SWITCHES

!

CAUTION

Read the appropriate sections to be fully aware of the consequences when changing switch settings.

Only qualified personnel should change switch settings.

These switches are set at the factory and do not need to be changed unless you intend to perform the following:

• Force download a new image file from a BootP server.

• Clear NVRAM and restore all user-entered parameters, such as the IP address and Subnet

Masks, to the SmartSwitch “Default” configuration settings.

• Clear user-entered passwords stored in NVRAM and restore the default passwords.

Figure B-1 shows the location of the mode switches and the switch settings for normal operation.

Figure B-1 Module Mode Switch Location/Component Layout

Switch definitions and positions are as follows:

• Switches 1 through 4 – For Cabletron Systems use only.

• Switch 5 – COM Port Autobaud. The default (OFF) position enables Autobaud sensing on the

COM port for Local Management sessions. Changing the switch to the ON position disables

Autobaud sensing and sets the COM port to 9600 baud for Local Management sessions.

• Switch 6 – Forced BootP. Changing the position of this switch (i.e., moving the switch from one position to the other) clears download information from NVRAM and forces the SmartSwitch to download a new image file from a BootP server after power to the chassis is restored.

NOTE

After changing the position of switch 6, DO NOT reapply power to the chassis until there is a station acting as a BootP server, which contains the image file.

• After changing the position of switch 6 and restarting the module, the module requests a new image download until they either receive a new image or the RESET button on the front panel is pressed. When the RESET button is pressed, the module continues trying to contact a BootP server, but will time out in approximately one minute. If the module times out, the image is downloaded from its FLASH memory.

• Switch 7 – Clear NVRAM. Changing the position of this switch resets NVRAM on the next power up. ALL user entered parameters, such as IP addresses, subnet masks, SNMP traps, and switching functions are restored to their factory default settings.

SIMM Upgrade

• Switch 8 – Reset Password/Community Strings. Changing the position of this switch clears only the user-entered passwords stored in NVRAM, and restores the default passwords. Once the module is reset, the passwords can either be reentered or the default passwords (Public and

ENTER) may be used.

NOTE

Do not change the position of switch 8 unless it is necessary to reset the module super-user configured passwords to their factory default settings.

B.2

SIMM UPGRADE

Memory upgrade is available for the SmartSwitch modules to expand the DRAM to 32 MB. This section explains how to locate and add/replace a Single In-line Memory Module (SIMM). For information on the available SIMM upgrades, contact Cabletron Systems. For details on getting

help, refer to Section 1.2
