Do you have QoS enabled? What does "show queueing interface Gi9/29" tell you? Output drops are "egress buffer overflow" drops, so technically it happens because the box tries to send a packet out an interface already in use (transmitting another packet) when there is no buffer space to store the packet until transmission. Micro-bursts and oversubscription are possible causes. Short queues exacerbate the problem. With "mls qos" enabled and no interface-specific adjustments you could have (too) short queues for the relevant traffic. -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
