I am running 12.1.20EW2 on SupIII..I have a 48 port GB-RJ card in it..I am dropping many packets that are TCP and seeing them re-transmitted..If I go to Sh platform cpu packet stat all..I see a Hardware CPUsubport drops..TXQUEUEnotavail..this is incrementing always.....Does anyone know if this is tied to the GIGABIT blocking arhcitecture of the 4448-GB-RJ...I can't see anything on the interfaces themselves dropping....
Packets Dropped In Hardware By CPU Subport (txQueueNotAvail)
CPU Subport TxQueue 0 TxQueue 1 TxQueue 2 TxQueue 3
"Sh platform cpu packet stat all"is not related to the oversubscribed line card. Issue a "show interface gig x/y counters detail" command and see if the Rx-No-Pkt-Buff,RxPauseFrames and TxPauseFrames counters are incrementing. These would indicate if you are running into the oversubscription issue.
We may have an overscription problem as the 'Rx-No-Pkt-Buff' counters are incrementing on some interfaces. Have searched cisco.com but cannot find any information on this. Can you please send a link or more information explaining what the counters actually mean.
