2 Release Notes for the Cisco 1548M Micro Switch 10/100

When Spanning Tree Protocol is enabled in some configurations, memory may become

corrupted, causing the switch to hang. Firmware Release v1.01.00 corrects this problem.

When monitoring ports on the switch, you will not see port activity for the corresponding port in

vertical alignment with the monitor port. This applies to traffic to or from the affected port, as

well as inputs from other ports that output to the affected port. [CSCdk83884]

For example, if Port 1 is the Monitor port, you will not be able to see traffic going into or out of

port 5, as well as any traffic coming into ports 2, 3, 4, 6, 7, and 8 that go out to port 5.

By default, Cisco Discovery Protocol (CDP) is disabled. When you enable CDP, the switch sends

and receives CDP packets. However, all CDP packets are forwarded to all ports. This results in

an inaccurate topology display for the device in Cisco network management applications.

[CSCdk59807]

You can only enable Spanning-Tree Protocol (STP) on VLAN 1. [CSCdk60304]

The Cisco ConfigMaker CD that shipped with your switch does not support this device. Contact

your Cisco representative or reseller to receive the correct version, or download the latest version

from CCO.

Before connecting a Micro Switch to a modem, you should configure your modem to ignore

input from the data terminal equipment (DTE) during dial-out or dial-in. Without this precaution,

there is a small chance that the modem could disconnect. Refer to your modem manual for the

correct configuration command syntax.
