Sup32 QOS - Packet Buffer

Unanswered Question
Mar 22nd, 2007


when appliying QOS to WS-X6548-GE-TX and WS-X6516A-GBIC with a Sup32 (12.2(18)SXF7) the following error message is displayed:

%C6K_PLATFORM-6-PACKET_BUFFER: This setting will cause a packet buffer error to take default action on a affected module.

It seems as the delay in these modules in VoIP conversations is higher than with the other switches (3560..).

Any experiences with this error message?

There is a bug assoicated with the problem: CSCeb59103 .

workaround is to Power-cycle or OIR the effected module by powering it off and on
