Chapter 1:

Introduction

1.3.1 Connectivity

The 6E122-26 and 6E132-25 connect to Ethernet networks or workstations through 24 RJ45 ports on the front panel. These ports support UTP connections up to 100 meters. The ports are IEEE 802.3 10BASE-T compliant.

The 6E123-26 and 6E133-25 connect to Ethernet networks or workstations through two RJ21 connectors on the front panel. These connectors support 25 pair cable at lengths up to 100 meters. The ports are IEEE 802.3 10BASE-T 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 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 up to 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 up to 200 Mbps of bandwidth.

6E12X-26 and 6E13X-25 Overview

1.3.3 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

1.3.4 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.

1.3.5 Switching Options

The 6E12X-26 and 6E13X-25 provide 802.1D switching, 802.1Q switching, or SecureFast Switching Virtual Network Services between all of the front panel interfaces including Fast Ethernet Interface Modules and High Speed Interface Modules (HSIMs).

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

The 6E12X-26 and 6E13X-25 provide IEEE 802.1D Spanning T ree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 6E12X-26 and 6E13X-25 support a wide variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB). A full suite of Cabletron Systems Enterprise MIBs provide a wide array of statistical information to enhance troubleshooting.

1.3.7 LANVIEW Diagnostic LEDs

LANVIEW diagnostic LEDs serve as an important troubleshooting aid by providing an easy way to observe the status of indi vidual ports and overall network operations. Chapter 4 provides details about the 6E12X-26 and 6E13X-25 LANVIEW LEDs.

1.3.8 Year 2000 Compliant

The 6E12X-26 and 6E13X-25 have an internal clock that can maintain the current time and date beyond the year 1999.

1.3.9 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 RARP or BootP server on the network.

The RAD requests start out at an interval of one second. The interv al 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 following brieﬂy explains each Chassis Conﬁguration screen ﬁeld:

MAC Address (Read-Only)

Displays the base physical address of the chassis.

6E122-26, 6E132-25, 6E123-26 and 6E133-25 User’s Guide 5-15

Chapter 5: Local Management

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.

Chassis Conﬁguration Screen

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.

5.11 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.
