I have several switches where I am getting incrementing hold queue drops to the tune of several thousand over a 5 minute period. These occur consistently throughout the day.
However these Hold Queue Drops (IQD) are only occurring on the VLAN201 interface. None of the physical interfaces show any drops or interface errors. Since this is a VLAN interface, are these drops actually affecting any of my workstations? Or does this mean that the Virtual Interface on the Switch is dropping the packets and it doesn't really matter? Below is an example of one switch:
sh int summary
*: interface is up
IHQ: pkts in input hold queue IQD: pkts dropped from input queue
OHQ: pkts in output hold queue OQD: pkts dropped from output queue
RXBS: rx rate (bits/sec) RXPS: rx rate (pkts/sec)
TXBS: tx rate (bits/sec) TXPS: tx rate (pkts/sec)
TRTL: throttle count
