Catalyst 2600 Release 3.1.2 Release Note

Catalyst 2600 Release 3.1.2 Release Note

These Release Notes provide specific information regarding this release of the Cisco Catalyst 2600 Token Ring Switch. These Release Notes document important operating environment considerations and known problem areas. References to the User Guide refer to the "Catalyst 2600 Token Ring Switch User Guide" (part # 78-3209-01) shipped with the Catalyst 2600.

Caution If your Catalyst 2600 is currently at Release 2.x.x, Release 3.1.2 of the Catalyst 2600 software must be downloaded to your switch using the serial port only. You cannot use TFTP to download this release of software. See your Catalyst 2600 Token Ring Switch User Guide for information about how to perform a serial port download.

Release 3.1.2 New Features of the Catalyst 2600

Software Release 3.1.2 provides support for Source-Route Bridging, which allows domains configured with different LAN segment numbers to be source-route bridged internally in the switch.

Data directed to one of the switch's own IP addresses cannot cross the internal bridge. In other words, the management station should use the IP address associated with the domain that is on its side of the internal bridge.

Known Problems

This section describes any known problems, anomalies, or design points.

ARI and FCI Status Indicators

The ARI and FCI status indicator bits are not set for frames that include an RI field. Customers with applications that depend on A and C bits should contact their vendor for information on whether or not a patch/fix is available.

Symptoms of possible ARI/FCI problems are:

The following is a list of drivers known to be affected by this problem. This list is provided for your information only and is not intended to be a complete list of affected drivers.

Driver Name Product Fixed Level
NETBEUI.OS2 OS/2 NetBIOS 5.00.0
DXMCOMOD.SYS DOS LSP (and DXMC1MOD) 1.38p
DXMJ0MOD.SYS DOS JetBEUI 1.38p

IFNDIS.SYS

TCP/IP v2.0 for OS/2 APAR pn77766
TCP/IP v3.0 for Warp Connect APAR ic11795
LANDD.OS2 OS/2 5.00.02
LANDD.NIF OS/2 5.00.02
NET.EXE DLS (DOS LAN Services)

A package called TRDRVFIX.EXE includes ALL the updated IBM drivers. This package is available from the following sources:

For IBM technical support: 1-800-426-7299 Call path 4, 6, 3

Token Ring Adapter for the IBM 9221

The Token Ring adapter for the IBM 9221 (ES/9000) Processor will not open when directly attached to a Catalyst 2600 port. You must use a multistation access unit or a controlled access unit.

Full-Duplex

This release of the Catalyst 2600 software does not support the capability of configuring a port to be full-duplex (FDX) only. All ports support the option (as defined by the 802.5R IEEE committee) of FDX protocol with an automatic drop-back to half-duplex (HDX) support. If a directly attached station attempts to open in HDX mode, the Catalyst 2600 ports will allow this and make the connection in HDX mode.

Maximum Frame Length

The maximum frame length supported by the Catalyst 2600 is 4540 bytes (including the Frame Control [FC] and the Frame Check Sequence [FCS] characters). Be sure to configure all network software, interconnecting products, workstations, and user applications to send frames no larger than 4540 bytes.
