Chapter 1:

Introduction

1.3.1 Connectivity

The 6E123-50 and 6E133-49 connect to Ethernet networks or workstations through 4 RJ21 ports on the front panel. These ports support 25-pair cable at lengths up to 100 meters. The ports are IEEE 802.3 10BASE-T compliant.

The 6E123-50 has two front panel slots (ports 5 and 6) for optional Fast Ethernet Interface Modules to support an uplink to 100 Mbps Fast Ethernet backbones or a high speed connection to a local server.

The 6E133-49 has one front panel slot for an optional High Speed Interface Module to provide for additional connectivity to other high speed networking technologies such as Asynchronous Transfer Mode (ATM), Fiber Distributed Data Interface (FDDI), and Wide Area Networks (WANs).

1.3.2 Full Duplex Switched Ethernet

The optional Fast Ethernet Interface Modules for the 6E123-50 can be conﬁgured to operate in Full Duplex Switched Ethernet mode, which provides 200 Mbps of bandwidth.

1.3.3 Management

Management of the 6E123-50, 6E133-49, 6C105 chassis and any optional equipment (Fast Ethernet Interface Modules and HSIMs) 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.

Page 17

6E123-50 and 6E133-49 Overview

1.3.4 Switching Options

The 6E123-50 and 6E133-49 provide 802.1D switching, 802.1Q switching, or SecureFast Switching Virtual Netw ork 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.

1.3.5 Standards Compatibility

The 6E123-50 and 6E133-49 are fully compliant with the IEEE 802.3 standard. The optional Fast Ethernet Interface Modules are fully compliant with the IEEE 802.3u standard. The 6E123-50 and 6E133-49 provide IEEE 802.1D Spanning T ree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 6E123-50 and 6E133-49 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.

1.3.6 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 ov erall network operations. Chapter 4 provides details about the 6E123-50 and 6E133-49 LANVIEW LEDs.

1.3.7 Year 2000 Compliant

The 6E123-50, 6E133-49 and 6C105 chassis have an internal clock that can maintain the current time and date beyond the year 1999.

Chapter 1:

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 RARP or BootP server on the network.

The RAD requests start out at an interval of one 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 RARP or BootP 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 6E123-50 and 6E133-49, the Fast Ethernet Interface Modules, the High Speed Interface Module (HSIM) and the 6C105 chassis. Local Management for the 6E123-50 and 6E133-49 provides the features described in Sections 1.4.1 through 1.4.5.

1.4.1 Remote Monitoring (RMON)

The 6E123-50 and 6E133-49 support 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.

1.4.2 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.

1.4.3 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).

1.4.4 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.

3.5.3 Connecting a Fiber Optic Segment to the

FE-100FX and FE-100F3

The FE-100FX and FE-100F3 have an SC style network port (see

Figure 3-5). Cabletron Systems supplies ﬁber optic cable that uses SC

style connectors that are keyed to ensure proper crossing over of the transmit and receive ﬁbers.

NOTES

Fiber Optic Network Connection

An odd number of crossovers (preferably one) must be maintained between devices so that the transmit port of one device is connected to the receive port of the other device and vice versa.

If the ﬁber optic cable being used has SC style connectors that do not resemble MIC style connectors, or has SC connectors on one end and a different type on the other, such as ST connectors, ensure that the proper crossing over occurs.

To connect an FE-100FX or FE-100F3 to the network, perform the following steps:

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.

Leave the protective rubber covers in place when the

Page 62

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)

When a valid IP address is assigned, the Subnet Mask ﬁeld

NOTE

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 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.

5-16 6E123-50 and 6E133-49 User’s Guide

Page 63

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 6E123-50 and 6E133-49 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.

The Port Redirect Function screen may not be available

NOTE

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.

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.

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.
