We have several 6500's, some of them heavily loaded. We use snmp to graph traffic on all interfaces - just the simplest solution. Since some time we have had an issue with the interface counters. When the CPU box is really loaded (usually synchronization of BGP sessions), the counters just freeze. The important thing is that only the displaying freezes, the counters are still counting. Both snmp and 'show interface' data is frozen and does not update for various time - from 30 seconds to 3-4 minutes. As the result we have spikes on graphs - there is always spike down, when snmp gives frozen data from the past, and after that spike up, when the counters unlock and start displaying correct data.
Just forgot to add - we have this issue with SXF14, 15, 16 and SXI1. -- Grzegorz Janoszka _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
