Hi,
I have a router 2801 with two physical interfaces and two virtual interfaces created on Fa0/0 interface.
#x
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES NVRAM up up
FastEthernet0/0.1 10.10.1.1 YES NVRAM up up
FastEthernet0/0.500 192.168.97.1 YES NVRAM up up
FastEthernet0/1 192.168.49.2 YES NVRAM up up
Tunnel1 unassigned YES NVRAM up down
Since 4 days I was getting HighQueueDropRate on Fa0/0 and there was no hight utilization at that times.
#sh int FastEthernet0/0
FastEthernet0/0 is up, line protocol is up

As per Cisco doc I enabled Priority Queue on the Ethernet interface to use four priority queues with varying queue limits. But still the Input queue drop rate is increasing.

Can someone please suggest me what needs to be done to stop the drop rate.
Thanks in advance.
