Introduction

1.3.1 Connectivity

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.

1.3.2 Full 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.

1.3.3 Management

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.

Introduction

1.3.8 Runtime 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.

1.4 LOCAL 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.

1.4.1 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 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

1.4.2 Remote 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.

1.4.3 Broadcast 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.

1.4.4 Port 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 allo ws 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).

Introduction

1.4.5 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 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

Chapter 3: Installation

3.6.1 Connecting Fiber Optic Cables to Ports 1 Thr ough 24 of the Modules

Each fiber optic link consists of two strands of fiber optic cabling: the transmit (TX) and the receive (RX). The transmit strand from a module port connects to the receive port of a fiber optic Ethernet device at the other end of the segment. The receive strand of the applicable port on the module connects to the transmit port of the fiber optic Ethernet device.
Cabletron Systems recommends labeling fiber optic cables to indicate receive and transmit ends. Many cables are prelabeled, providing matching labels or tapes at both ends of each strand of cable.
The instructions which follow detail the process used to connect an ST connector to a module port.
1. Remove the protective plastic covers from the fiber optic ports on the
applicable port on the module, and from the ends of the connectors on each fiber strand.
NOTE
CAUTION
Leave the protective rubber covers in place when the connectors are not in use to prevent contamination.
Do not touch the ends of the fiber optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants.
!
Contamination of the ends causes problems in data transmissions. If the ends become contaminated, blow the surfaces with a canned duster. A fiber port cleaning swab saturated with optical-grade isopropyl alcohol ma y also be used to clean the ends.
2. Refer to Figure 3-2 and attach one fiber to the applicable receive (RX)
port on the module. Insert the ST connector into the port with the alignment slot on the connector inserted over the locking key on the port. Turn the connector clockwise to lock it down.
3. Attach the other fiber of the pair to the applicable transmit (TX) port
on the module. Use the same procedure for insertion of the ST connector.

The following briefly explains each Chassis Configuration screen field:
MAC Address (Read-Only)
Displays the base physical address of the chassis.
5-16 6E128-26, 6E138-25, 6E129-26 and 6E139-25 User’s Guide
Chassis Configuration Screen
IP Address (Modifiable)
This field allows the IP address to be set for the 6C105 chassis. If an IP address is assigned to the 6C105 chassis all the interface modules installed in the chassis can be managed via this IP address, eliminating the need to assign an IP address to each interface module. To set the IP address, refer to Section 5.7.1.
Subnet Mask (Modifiable)
NOTE
When a valid IP address is assigned, the Subnet Mask field automatically enters the default mask that corresponds with class of IP entered in the IP Address field. Some firmware revisions do support changing the chassis subnet mask from the default value. Refer to your Release Notes to ensure that the Subnet Mask is a modifiable field.
Displays the subnet mask for the chassis. A subnet mask “masks out” the network bits of the IP address by setting the bits in the mask to 1 when the network treats the corresponding bits in the IP address as part of the network or subnetwork address, or to 0 if the corresponding bit identifies the host. The 6C105 chassis automatically uses the default subnet mask that corresponds to the IP class that was entered in the IP address field.
Section 5.7.2, Setting the Subnet Mask describes how to change the
subnet mask from the default value.
Chassis Date (Modifiable)
Contains a value that the chassis recognizes as the current date. When the chassis date is modified and saved all interface modules installed in the chassis are set to this date. To set a new chassis date, refer to
Section 5.7.3.
Chassis Time (Modifiable)
Contains a value that the chassis recognizes as the current time. When the chassis time is modified and saved, all interface modules installed in the chassis are set to this time. To enter a new time, refer to Section 5.7.4.
Screen Refresh Time (Modifiable)
Contains the rate at which the screens are updated. This setting determines how frequently (in seconds) information is updated on the screen. To enter a new update time, refer to Section 5.7.5.
6E128-26, 6E138-25, 6E129-26 and 6E139-25 User’s Guide 5-17
Chapter 5: Local Management
Screen Lockout Time (Modifiable)
Contains the maximum number of minutes that the Local Management application displays a module’s screen while awaiting input or action from a user. For example, if the number 5 is entered in this field, the user has up to five minutes to respond to each of the specified module’s Local Management screens. In this example, after five minutes of “idleness” (no input or action), the terminal “beeps” five times, the Local Management application terminates the session, and the display returns to the Password screen. To enter a new lockout time, refer to Section 5.7.6.
Chassis Uptime (Read-Only)
Displays the total time the chassis has been operating. The chassis uptime is based on which interface module installed in the chassis has been operating for the longest period of time.
Operational Mode (Toggle)
This field allows the user to set all the modules in the chassis to operate as traditional switches (802.1D SWITCHING option), or as IEEE 802.1Q switches (802.1Q SWITCHING option).
In 802.1D SWITCHING mode, the 24 ports located on the front panel, and each Fast Ethernet Interface Module, and HSIM port(s) are bridged to each other.
When the operational mode is set to 802.1Q SWITCHING, the 6E12X-26 and 6E13X-25 act as IEEE 802.1Q switches. The modules are able to increase their switching functionality by creating and maintaining port based Virtual LANs (VLANs).
For details on how to select the Operational Mode, refer to Section 5.7.7.

5.7.1 Setting the IP Address

To set the IP address, perform the following steps:
1. Use the arrow keys to highlight the IP Address field.
2. Enter the IP address into this field using Decimal Dotted Notation
(DDN) format. For example: 134.141.79.120

Chassis Configuration Screen
3. Press ENTER. If the IP address is a valid format, the cursor returns to
the beginning of the IP address field. If the entry is not valid, the Event Message Line displays “INVALID IP ADDRESS OR FORMAT ENTERED”. Local Management does not alter the current value and refreshes the IP address field with the previous value.
4. Use the arrow keys to highlight the SAVE command, then press
ENTER. The “SAVED OK” message displays indicating that the changes have been saved to memory.

5.7.2 Setting the Subnet Mask

If the management workstation that is to receive SNMP traps from the 6C105 is located on a separate subnet, the subnet mask for the 6C105 must be changed from its default.
NOTE
When a valid IP address is assigned, the Subnet Mask field automatically enters the default mask that corresponds with class of IP entered in the IP Address field. Some firmware revisions do support changing the chassis subnet mask from the default value. Refer to your Release Notes to ensure that the Subnet Mask is a modifiable field.
To change the subnet mask from its default, perform the following steps:
1. Use the arrow keys to highlight the Subnet Mask field.
2. Enter the subnet mask into this field using Decimal Dotted Notation
(DDN) format. For example: 255.255.255.0
3. Press ENTER. If the subnet mask is valid, the cursor returns to the
beginning of the Subnet Mask field. If the entry is not valid, the Event Message Line displays “INVALID SUBNET MASK OR FORMAT ENTERED”. Local Management does not alter the current value, but it does refresh the Subnet Mask field with the previous value.

5.11 PORT REDIRECT FUNCTION SCREEN

NOTE
The Port Redirect Function screen may not be available depending on the operational mode that has been set for the chassis. Refer to your Release Notes to see what operational modes support the Port Redirect Function. Refer to
Section 5.7.7, Setting the Operational Mode, for instructions
on configuring the operational mode of all the modules installed in the chassis.
The Port Redirect Function screen, Figure 5-14, allows the user to set each one of the modules in the chassis (1 through 5), and the ports of the corresponding module installed, as a source or destination port. A port can be set to have one or more destination ports and chassis module slot numbers. For example, port 1 in module (slot) 1 can be set as a source port with three destinations, ports 2, 3, and 4 in module (slot) 3. Traffic from port 1 in module 1 is then automatically redirected to ports 2, 3, and 4 in module 3. Port 1 in module 1 can also serve as a destination port for other ports and modules. The port redirect function is extremely useful for troubleshooting purposes, as it allows traffic to be sent to a particular port(s) where, with the use of an analyzer or RMON probe, all current traffic from the source port(s) can be examined.
NOTES
The module number corresponds to the slot number in which the module resides in the 6C105 chassis (1 through 5).
Although traffic from the source port (including, if desired, errored frames) is sent to the destination port, normal switching is still performed for all frames on the source port.
Access the Port Redirect Function screen from the Chassis Menu screen by using the arrow keys to highlight the PORT REDIRECT FUNCTION menu item and pressing ENTER. The Port Redirect Function screen, Figure 5-14, displays.
