Release Notes for Catalyst 2820 Series and Catalyst 1900 Series Firmware Version 5.34


March 3, 1997

These release notes describe the new features and caveats in the Catalyst 2820 and the Catalyst 1900 Version 5.34 firmware. This firmware runs on the Catalyst 2820 and Catalyst 1900.

The product documentation for the Catalyst 2820 and Catalyst 1900 is as follows:

Catalyst 2820 Series and Catalyst 1900 Series Installation and Configuration Guide

Catalyst 2820 Modules User Guide

Catalyst 2820 Series and Catalyst 1900 Series MIB Reference Manual

New Features

This version adds automatically-refreshed statistics. If you are using VT100 terminal emulation, screens displaying statistics are refreshed every 5 seconds.

Modifications

The following modification is included in Version 5.34:

When port monitoring is enabled with port B as the monitor port, no packets from the ports being monitored are sent to it. Version 5.34 fixes this problem.

Current Caveats

This section lists possibly unexpected behavior by Version 5.34.

Unterminated RS-232 Cables

An RS-232 cable that is connected to a switch-but not connected to a device at the other end-might cause the switch to reset.

Upgrading from Version 5.25 to Version 5.34

If you have customized any Version 5.25 parameters, the upgrade to Version 5.34 resets these parameters to their factory default values. Reset them to your customized settings after the upgrade. (The 5.34 default values of the configurable parameters have not changed from Version 5.25.)

The following parameters return to the listed factory default values when you upgrade to Version 5.34 from 5.25.
