Receive Discards
jfarney
We have suddenly seen a huge number of Receive Discards on two HP switches that are connected to a blade server enclosure that is connected to a Cisco core.
Is there any way through Orion, the Engineer's Toolkit, or any other relatively straightforward way to see what the packets are that are being discarded?
We have hit a bit of a road block troubleshooting this issue and any help would be appreciated.
Thanks,
John

This usually indicates server congestion. It can't handle any more packets, so the switch tries to queue them up. Once the queues/buffers are full, the packets are discarded.
In a "trunked" environment you will see discards when the far end is missing a vlan configured on the trunk. All broadcast traffic in that vlan will be discarded by the switch port.
Do a search for discard on these forums, to see what others have discovered.
