Introduction

This chapter introduces the 6H308-24 and 6H308-48 Fast Ethernet switching modules.
Important Notice
Depending on the firmware version used in the module, some features described in this document may not be supported. Refer to the Release Notes shipped with the module to determine which features are supported.
The 6H308-24 module (Figure 1-1) features 24 100BASE-FX switched ports connected via 24 MT-RJ fiber connectors. The 6H308-48 module (Figure 1-1) features 48 100BASE-FX switched ports connected via 48 MT-RJ fiber connectors.
Each of the fixed front panel ports can operate in either half-duplex or full-duplex mode of operation, as determined by auto-negotiation. Full-duplex can also be manually configured.
Each module is a high-speed network switch that supports IEEE 802.1D switching (bridging). Distributed Chassis Management (DCM) and SecureFast Switching (SFS) functionality is not supported when the modu le is installed in the MATRIX E7. Both DCM and SFS are supported fo r this module when it is installed in the 6C105 SmartSwitch 6000 chassis.
The module ports can be configured to control tr affic in several ways, incl udi ng prioritizing traffic flow according to protocol type. The module can also be configured to establish 802.1Q 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 Enterasys Networks MATRIX E7 Series and S martSwitc h 6000 Series Modul es Local Manage ment User’s Guide.
The module receives power and backplane connectivity when it is inserted into an Enterasys Networks MATRIX E7 or 6C105 chassis.

Connectivity

1.1 CONNECTIVITY

The module connects t o Ethernet net works or w orkstatio ns through the fr ont panel conne ctors. The ports are IEEE 802.3 100BASE-FX compliant, using MT-RJ fiber connectors for multimode fiber.

1.2 RUNTIME IP ADDRESS DISCOVERY

This feature enables the module 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 module 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 link. If a link is discovered, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address 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 requests contin ue u ntil an IP a ddress is re cei ved from a RARP or BootP serv er, or an IP address is entered using Local Management.
NOTE: The module will reboot after RAD is successful.

1.3 HALF-DUPLEX/FULL-DUPLEX AUTO-NEGOTIATION

The fixed front panel ports on the module 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 exchange 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 module can adjust to full-duplex operation when the device on the other end of the connection can also adjust from half-duplex to full-duplex. I f t he device on the other en d of th e connection can only operate in half-duplex mode, then the module simply adjusts to operate in half-duplex mode.
Introduction 1-3
SmartTrunk

1.4 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, t hen the other interface automatically comes out o f Bloc king 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 configure the SmartSwitch module, refer to the MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management User’s Guide.

1.5 REMOTE MONITORING (RMON)

The module 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 any SNMP MIB variable. The Action can be tr igg ere d 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.

1.6 BROADCAST SUPPRESSION

Broadcast Suppressi on enables a user to s et a desire d limit of re cei ve br oadcas t frames per port/per second to be forwarded out the other ports on the module. Any broadcast frames above this specified limit ar e dropped. In the event tha t bro adc ast fr ames ar e bei ng su ppressed, multicast and unicast frames continue to be switched.
1-4 Introduction
Port/VLAN Redirect Functions

1.7 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 p robe will see the data as if it were dir ectly conn ected to the LAN se gment of the source port.
The VLAN redirect func ti on i s similar to the port red ir ect f unction except that t he fr ames r eceived by the module are r edire cted t o a des ignat ed dest inati on port accor ding t o the VLAN c lassi f icat ion 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.

1.8 TRAFFIC RATE LIMITING

The Traffic Rate Limiting feature enables the SmartSwitch device to control traffic rates on a per-port, per-priority basis . The n etw ork adminis trator can conf i gure a rat e 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.
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 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 segments.
For more information about the application of the Traffic Rate Limiting function, refer to the Enterasys Networks MATRIX E7 Series and S martSwitc h 6000 Series Modul es Local Manage ment
User’s Guide.
Introduction 1-5
Flow Control

1.9 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 is accomplished by the transmitting device pausing its transmission while the receiving device processes the frames already received.
The module supports frame based 802.3x flow control. 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.

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 rul es, tha t outl ines a mec hanism fo r propa gati ng the por t stat e 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 suc h as VLAN and mu ltic ast gro up membershi p. F or more det ails on ho w GVRP and GMRP handle frames under GARP, and how to conf igure t he switch po rts to ta ke adv anta ge of this operation, refer to the Enterasys Ne tworks MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management User’s Guide.

1.11 802.1 PORT PRIORITY

The 802.1 por t priority is u sed to assign a default priority to the frames received without priority information in their tag header, map prioritized frames to the appropriate transmit queues, and prioritize frames according to protocol type. The 802.1 port priority is part of the IEEE 802.1D standard.
1-6 Introduction
Distributed Chassis Management

1.12 DISTRIBUTED CHASSIS MANAGEMENT

Installation in the 6C107 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 6C105 chassis. Refer to the Enterasys Networks MATRIX E7
Overview and Setup Guide
for more information.
Installation in the 6C105 SmartSwitch 6000 Chassis
The 6C105 SmartSwitch 6000 chassis ca n be viewed as a single entity with a singl e IP addre ss. Its systems management functions are distributed to all modules, including the module. The chassis can be managed using a single IP addr ess, or the modul es can be managed sep arately by indi vidu al 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 settings are done by selecting the specific module to be modified and changing the settings for that module.

1.13 MANAGEMENT

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 u nless a BootP server has be en configured for the modul e. The BootP server references the location of a station acting as a Trivial File Transfer Protocol (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 one of these requirements is not met, the module continues to request 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 device. All user -ente red pa ramete rs, such as the I P addre ss, device names, 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 factory 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.
