1.36E12X-26 AND 6E13X-25 OVERVIEW

The 6E12X-26 and 6E13X-25, shown in Figure 1-1, are interface modules for Cabletron Systems 6C105 SmartSwitch 6000 chassis.

The 6E12X-26 and 6E13X-25 are high-speed network switch devices that support 802.1D switching (bridging), 802.1Q switching, and Cabletron Systems SecureFast Switching Virtual Network technology. Ports 25 and 26 of the 6E12X-26 support optional Fast Ethernet Interface Modules and can provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet networks. The 6E13X-25 is capable of being equipped with a High Speed Interface Module (HSIM) that provides for additional connectivity to other high speed networking technologies such as Asychronous Transfer Mode (ATM), Wide Area Networks (WANs), Gigabit Ethernet and Fiber Distributed Data Interface (FDDI).

The 6E12X-26 and 6E13X-25 can be used to connect individual high-bandwidth user devices, such as workstations, and to provide a central switching point for multiple Ethernet segments using devices such as Cabletron Systems HubSTACK or other third party stackable devices.

NOTE	Figure 1-1 displays the 6E128-26 and 6E138-25. The
	6E128-26 and the 6E129-26 are functionally identical, as are
	the 6E138-25 and the 6E139-25. The only difference being that
	the 6E129-26 and 6E139-25 modules support single mode
	fiber optic cabling.

Chapter 1: Introduction

1.3.1Connectivity

The 6E128-26 and 6E138-25 connect to Ethernet networks or workstations through 24 ST fiber optic ports on the front panel. These ports support multimode fiber optic cables at lengths up to 2 kilometers. The ports are IEEE 802.3 10BASE-F compliant.

The 6E129-26 and 6E139-25 connect to Ethernet networks or workstations through 24 ST fiber optic ports on the front panel. These ports support single mode fiber optic cable at lengths up to 5 kilometers. The ports are FOIRL compliant.

The 6E12X-26 modules have two front panel slots (ports 25 and 26) for optional Fast Ethernet Interface Modules to support an uplink to

100 Mbps Ethernet backbones or a high speed connection to a local server.

The 6E13X-25 modules have one front panel slot for an optional High Speed Interface Module to provide for additional connectivity to other high speed networking technologies such as ATM, WANs, Gigabit Ethernet and FDDI.

1.3.2Full Duplex Switched Ethernet

Each switched Ethernet port supports full wire-speed Ethernet communications and can be configured to operate in Full Duplex Switched Ethernet mode, which provides 20 Mbps of bandwidth.

The optional Fast Ethernet Interface Modules for the 6E12X-26 can also be configured to operate in Full Duplex Switched Ethernet mode, which provides 200 Mbps of bandwidth.

1.3.3Management

Management of the 6E12X-26 and 6E13X-25 is accomplished using Local Management tools 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.

Chapter 1: Introduction

1.3.8Runtime IP Address Discovery

This feature enables the modules to automatically accept an IP address from a BootP server on the network into NVRAM without requiring a user to enter an IP address through Local Management.

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 BootP or RARP server on the network.

The RAD requests start out at an interval of 1 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 BootP or RARP server, or an IP address is entered using Local Management.

1.4LOCAL MANAGEMENT FEATURES

Local Management provides the tools that allow management of the 6E12X-26 and 6E13X-25, the Fast Ethernet Interface Modules, all HSIMs, and the 6C105 chassis. Local Management for the 6E12X-26 and 6E13X-25 provides the features detailed in Sections 1.4.1 through 1.4.6.

1.4.1Distributed Chassis Management

From a management perspective, the 6C105 SmartSwitch 6000 chassis can be viewed as a single entity with a single IP address. Its management functions are distributed to all modules. This means a single module in the chassis, such as the 6E12X-26 and 6E13X-25, can be used to manage the entire chassis, and any other attached module through Local Management, SNMP, or Telnet applications.

Local Management Features

1.4.2Remote Monitoring (RMON)

The 6E12X-26 and 6E13X-25 supports all Ethernet RMON groups, which include Statistics, Alarms, Events and History. These 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 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.

1.4.3Broadcast Suppression

Broadcast Suppression allows 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.

1.4.4Port Redirect Function

The port redirect function, also referred to as “Port Mirroring,” is a troubleshooting tool used to map traffic from a single source port or multiple source ports to a destination port(s) within the chassis. This feature functions at the bit level, which allows all packets, 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 is directly connected to the LAN segment of the source port(s).

1.4.5SmartTrunk

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 SmartTrunk benefits are as follows:

•All purchased bandwidth is used.

•Distributed, resilient links increase reliability and performance.

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

For more information about SmartTrunk, refer to the Cabletron Systems

SmartTrunk User’s Guide.

1.4.6Additional Local Management Functions

Local Management also allows the following tasks to be performed:

•Manage any module installed in the 6C105 via a single terminal connection.

•Assign an IP address and subnet mask to the 6E12X-26 and 6E13X-25 modules and 6C105 chassis.

•Select a default gateway.

•Control local and remote access.

•Designate workstations to receive SNMP traps from the 6E12X-26 and 6E13X-25 modules and 6C105 chassis.

•Configure module specific SNMP MIB objects including the IETF Bridge MIB objects.
