I have a 4506 with a trunk port.
In this port I can see that the counter:
Tx-Drops-Queue-1 have 5669 packets drops.
The trunk is with an HP switch, the config of vlans in trunk included native is ok.
I see the buffers and I think is ok:
Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 9845
Queueing strategy: fifo
Output queue: 0/40 (size/max)
Any ideas of the "why" of this drops?
Thanks in advance.
