xiv About This Guide

Introduction

This chapter introduces the 6H352-25 Fast Ethernet switching module.

Important Notice

Depending on the firmware version used in the 6H352-25, some features described in this
document may not be supported. Refer to the Release Notes shipped with the 6H352-25 to
determine which features are supported.

The 6H352-25 module (Figure 1-1) features 24 10BASE-T/100BASE-TX switched ports
connected via 24 RJ45 front panel connectors, and one High Speed Interface Module connector
that allows an optional HSIM or VHSIM to be installe d in the module for connections to high
speed services.

1

Each of the fixed front panel ports can operate in either half-duplex or full-duplex mode of
operation, as determined by auto-negotiation. Speed (10/100) or duplex can al so be manually
configured.

The 6H352-25 is a hi gh-speed network switching module that supports IEEE 802.1D switching
(bridging). Distributed Chassis Management (DCM) and functionality is not supported when the
module is installed in the MATRIX E7. However, DCM is supported when the 6H352-25 module
is installed in the SmartSwitch 6000 chassis.

The 6H352-25 ports can be configured to control traffic in several ways, including prioritizing
traffic flow according to protocol type. The 6H352-25 can also be configured to establish 802.1Q
V irtua l Local Are a Networ ks (VLANs) and contro l the flo w of frames ass ociated wit h each VLAN
according to priority and Ether type. Detailed information about VLANs is provided in the
Enterasys Networ ks MATRI X E7 Serie s and Smart Switch 60 00 Series Modules Loc al Manag ement
User’s Guide.

The 6H352-25 receives power and backplane connectivity when it is inserted into an Enterasys
Networks MATRIX E7 or SmartSwitch 6000 chassis.

Connectivity

1.1 CONNECTIVITY

The 6H352-25 connects to Ethernet networks or workstations through the front panel connectors.
The ports support Unshielded Twisted Pair (UTP) cables with an impedance between 85 and 111
ohms at lengths up to 100 meters. The ports are IEEE 802.3 10BASE-T and 100BASE-TX
compliant.

1.2 OPTIONAL HSIMs AND VHSIMs

Optional HSIMs and VHSIMs are available from Enterasys Networks for additional connectivity
to various networking technologies. The HSIMs and VHSIMs available for the 6H352-25 are
listed in the Release Notes shipped with the module.

1.3 RUNTIME IP ADDRESS DISCOVERY

This feature enables the 6H352-25 to automatically accept an IP address from a Boot Strap
Protocol (BootP) server on the network without requiring a user to enter an IP address through
Local Management.

When the 6H352-25 is connected to the network and powered up, Runtime IP Address Discovery
(RAD) checks the module for an IP address. If one has not yet been assigned (module IP address
set to 0.0.0.0), RAD checks to see if any of the module interfaces have a li nk. If a link is
discovered, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to
obtain an IP addr ess from a 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 requ ests contin ue unti l an I P addre ss is received from a RARP or BootP ser ve r,
or an IP address is entered using Local Management.

NOTE: The 6H352-25 will reboot after RAD is successful.

Introduction 1-3

Half-Duplex/Full-Duplex Auto-Negotiation

1.4 HALF-DUPLEX/FULL-DUPLEX AUTO-NEGOTIATION

The fixed front panel ports on the 6H352-25 have the ability to auto-negotiate the ports’ mode of
operation (half-duplex or full-duplex) between two devices according to the 802.3x standard.
During Auto-Negotiation, two devices automatically exc hange information “telling” each other
their current operating mode. The Auto -Negotiation feature targets the maximum capability that
can be reached between the two devices. For example, the 6H352-25 can adjust to full-duplex
operation when the device on the other end of the connection can also adjust from half-duplex to
full-duple x. I f t he device on the other end of t he connection can only operate in hal f -dup lex mode,
then the 6H352-25 simply adjusts to operate in half- duplex mode.

1.5 SmartTrunk

Traditional 802.1D Spanning Tree Bridges only allow one active data path between any two
switches; all other parallel data paths are in Standby or Blocking mode. If one interface or path
should fail, then the other interface automatically comes out of Bloc kin g mode and forwards all of
the traffic. This is fine for redundancy purposes. However, it is not the most efficient use of
resources.

SmartTrunk, also referred to as SmartTrunking, is Enterasys Networks’ terminology for load
balancing or load sharing. SmartTrunk provides the ability to take full advantage of the network’s
redundant bandwidth. SmartTrunk divides network traffic across multiple ports in parallel to
provide additional throughput. The SmartTrunk application can be used with any of Enterasys
Networks’ switch modules (except ATM modules).

For more information about SmartTrunk and how to configur e the SmartSwitch, refer to the

MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management User’s Guide.

1.6 REMOTE MONITORING (RMON)

The 6H352-25 supports all nine Ethernet RMON groups. The Statistics, Alarms, Events and
History groups are enabled on all ports by default.

Enterasys Networks RMON Actions is a vendor-specific extension of RMON and provides the

ability to set an “Action” on an y SNMP MI B variable. The Action can be triggered by any 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.

1-4 Introduction

Broadcast Suppression

1.7 BROADCAST SUPPRESSION

Broadcast Suppres sion enabl es a user to se t a desi red limit of recei v e broadc ast frames per port/pe r
second to be forwarded out the other ports on the m odule. Any broadcast frames above this
specifi ed limi t are dropped. In the event that bro adcast frames are being suppressed, multic ast and
unicast frames continue to be switched.

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 module. This 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 da ta as if it were di rectly connected to the LAN se gment
of the source port.

The VLAN redirect f unc ti on is similar to the port red ir ect f unc tion except that the frames r ece ived
by the module are r edirect ed to a design ated de stina tion port ac cordi ng to t he VLAN cla ssif i cati on
of the frames received. Multiple VLANs can be directed to the same destination port. The VLAN
redirect function is only supported when the module is operating as an 802.1Q switch.

1.9 TRAFFIC RATE LIMITING

The Traffic Rate Limiting feature enables the SmartSwitch device to control traffic rates on a
per-port, per-priority basis. The netw or k admin istr ator can co nf igur e a r ate l imit (f rom 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 tr affic 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.

Administrators can configure up to four rate limit rules per port; however, each rule must not
include conflict ing 802.1p priority values. In order to control inbound and outbound traffic on the
same port, two rate limiting rules must be configured (one for inbound and one for 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.

NOTE: This Traffic Rate Limiting function is not supported on ports connected to
SmartTrunk segm ents.

For more information about the application of the Rate Limiting function, refer to the Enterasys
Networks MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management User’s

Guide.

Introduction 1-5

Flow Control

1.10 FLOW CONTROL

Flow control is a method of managing the flow of frames between two devices. It ensures that a
transmitting device does not saturate a receiving device with data. This is accomplished by the
transmitting device pausing its transmission while the receiving device processes the frames
already received.

The 6H352-25 supports the following two types of flow control:

• Frame based 802.3x

• Back pressure

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 Eth ern et ports operating in the half-duple x mode of
operation. Flow control can be enabled or disabled on a port-by-port basis.

1.11 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 ou tline s a mechani sm for pr opaga ting t he port s tate a nd/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 attribu tes such as VLAN and mult icast group member ship. F or mor e detai ls on how GVRP
and GMRP handle frames u nder GARP, an d how t o conf igure t he switch po rts to ta ke adv anta ge of
this oper ation, refer to the Enterasys N etworks MATRIX E7 Series and SmartSwitch 6000 Series
Modules Local Management User’s Guide.

1.12 802.1 PORT PRIORITY

The 802.1 port priority is used to assign a default priority to the frames received without priority
information in their tag header, map prio ritized frames to the appropriate t ransmit queues, and
prioritize frames according to protocol type. The 802.1 port priority is part of the IEEE 802.1D
standard.

1.13 DISTRIBUTED CHASSIS MANAGEMENT

Installation in the MATRIX E7 Chassis

From a management perspective, 6x3xx modules in the MATRIX E7 chassis can be managed
separately by individual IP addresses. Any modules in the MATRIX E7 can be selected and
managed, however, no overall system wide settings are available.

NOTE: The MATRIX E7 chassis does not allow Distributed Chassis Management
functionality as in the SmartSwitch 6000 chassis. Refer to the Enterasys Networks
MATRIX E7

Overview and Setup Guide

Installation in the SmartSwitch 6000 chassi s

The SmartSwitch 6000 chassis can be viewed as a single entity with a single IP address. Its
systems management funct ions are dist ribute d to all modules, incl uding the 6H352-25. The chassis
can be managed using a single I P address, or th e modules can be manage d separate ly by ind iv idual
IP addresses. When the IP address of the chassis is used, system wide settings can be done from
the chassis menu in Local Management, while module setti ngs are done by selecting the specific
module to be modified and changing the settings for that module.

for more information.

1.14 MANAGEMENT

Management of the module can be either in-band or out-of-band. In-band remote management is
possible through any SNMP compliant Network Management Software, such as Enterasys

Networks’ Webview and Aprisma’s SPECTRUM for Open Systems suite of management
products. Out-of-band Local Management is provided through the RJ45 COM port on the front
panel using a VT100 terminal or a VT100 terminal emulator.

Local Management, described in a separate Enterasys Networks document, provides the ability to
manage the 6H352-25. Refer to the MATRIX E7 Series and SmartSwitch 6000 Series Modules

Local Management User’s Guide for more information.

1.15 SWITCHING OPTIONS

The 6H352-25 provides 802.1Q switching between all of the front panel interfaces. In the 802.1Q
mode (the default mode of operation), the 6H352-25 functions as an 802.1D switch until VLANs
are configured.

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

B.2 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.

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

These switches are set at the factory and rarely need to be changed.
Switch definitions and positions are as follows:

• Switches 1 through 4 – For Enterasys Networks use only.

• Switch 5 – COM Port Autobaud. The de f au lt (OFF) position enables Autobaud sens ing on the

COM port for Local Mana gement sessions. Changing the switch to the ON position disables
Autobaud sensing and sets the COM port to 9600 baud for Local Management sessions.

Setting the Mode Switches

• Switch 6 – Forced BootP.

NOTE: After changing the position of Switch 6, DO NOT reapply power to the module
until there is a station on the network acting as a BootP server, which contains the
downloadable firmware image file.

DO NOT attempt a Forced BootP unless a BootP server has been configured for the module.
The BootP server references the location of a station acting as a Trivi al File Trans fe r Pro toc ol
(TFTP) server containing the module image file.

When the position of Switch 6 is changed and the power is cycled to the module, the device
requests the image file location from the BootP server and uses TFTP to download the image
from the TFTP server . If o ne of thes e requ irement s is not met , the mod ule co ntinue s to r equest
either the BootP server or the TFTP server until the RESET button on the module is pressed.
Once the RESET button is pressed, the module resets after one minute and loads the image
stored in FLASH memory.

• Switch 7 – Clear NVRAM. Changing the position of this switch resets NVRAM on the next

power -up of the devic e. All user -entered pa rameters, suc h as the IP ad dress, de vice name s, etc.,
are reset to the factory default settings. Once the module resets, you can either use the factory
default settings or reenter your own parameters.

• Switch 8 – Reset Password/Community Names. Changing the position of this switch clears

user-entered passwords stored in NVRAM, and restores the fact ory default passwords on the
next power-up of the device. Once the module resets, you can either use the factory default
settings or reenter your own passwords.

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