Open Problem Reports and Feature Exceptions

PR 107231

A stack of 3 OS6850's (slots 1 & 2 are 48 ports and slot 3 is 24 ports) with a mobile port of 1/35 (Second Asic on Slot 1) and a binding mobile rule. A MAC violating is programmed as filtered. Now, this filtered MAC is programmed on all slots. However, since there is only one ASIC on Slot 3, there is an error and the address is not programmed as filtered on slot 3.

Workaround: There is no known workaround at this time.

PR 89316

A BPDU packet with the Root BridgeID of 0xffff...is sent out with every link-up to elicit a BPDU reply from the adjacent switch in the current Auto-Edge Detection mechanism.

Workaround: There is no known workaround at this time.

PR 90297

On an OS6800/OS9000, CST Root convergence in 802.1s may be slow due to the circulation of old ‘good’ spanning tree vectors in the network when a root switch is powered off.

Workaround: 1) Use single MSTP region as much as possible. 2) Tune the performance parameters maxAge and hop count to optimal values for the network.

PR 95308

Temporary traffic loops could happen under the following scenarios:

1. Reloading of a non-root bridge.

This happens when the bridge is going down and is due to the sequential bringing down of NIs during a reload process. It is purely temporary in nature and stops when all the NIs eventually get powered off.

2. NI power down

When an NI power down command is executed for an NI and if that NI has the Root port and other NIs have Alternate ports, it is possible to see some traffic looping back from the newly elected Root port. The traffic loop back is temporary and will stop once the NI gets powered off.

3. New Root bridge selection

Temporary loops could occur during the process of electing a new Root bridge, if this election process is triggered by the assignment a worse priority for the existing root bridge or a root bridge failure. This happens due to the inconsistent spanning tree topology during the convergence and stops entirely once the network converges.
