This document describes the known (open) problems for this release.
Sections in this document include the following:
This section lists the currently known problems.
Problem Identifier: CSCdj73405
Problem Description: Occasionally, the Catalyst 3900 ATM module start-up diagnostics will erroneously report the following message:
WARNING: FATAL ATM Module Boot Failure
Port = xx, Code = 22, msg = MP SAR Framer loopback test failed
If this error occurs during the Catalyst 3900 power-on diagnostics, the ATM port will be marked as failed and will be disabled.
Recommended Action: Disconnect the power cord from the Catalyst 3900 for at least 15 seconds and then reconnect the power cord. If the problem re-occurs, then repeat this action.
Problem Identifier: CSCdj69326
Problem Description: The ATM module currently uses an IP address of 0.0.0.0 when queried by ILMI. Because this is an invalid address, ATM network management agents (such as CSWI) will exclude the ATM module from their network map.
Recommended Action: None.
Problem Identifier: CSCdj64419
Problem Description: When running the Spanning-Tree Protocol on a TrBRF, it is possible for the logical port of the TrCRF that contains the ATM port to go into the BLOCKED state while TrCRFs that contain only Token Ring ports are in the FORWARDING state. This is because the TrBRF spanning-tree algorithm does not take into account the port cost or port priorities of individual ports within a TrCRF when it makes topology decisions.
Recommended Action: To counter this problem, change the STP Cost (on the Spanning Tree for TrCRF panel) for the TrCRF that contains the ATM port to a lower value, thereby allowing the TrCRF to remain in the FORWARDING state.
