Diagnosing Packet Loss on ASR9K

Level 1

Hi,

 

An end customer has a voip setup and has noticed some very intermittent and occasional packet loss on an IP belonging to us. I cannot see any issues on the interface level but would need some assistance interpreting the results of the NP and fabric level.

 

Your help would be very much appreciated.

 

These are the run commands I have run to determine the issue.

 

show controllers np ports all location 0/3/CPU0
show controllers np counters all location 0/3/CPU0
show controllers np fabric-counter all all location 0/3/CPU0
show controllers np tm counters all location 0/3/CPU0
show controllers fabric fia bridge stats location 0/3/CPU0
show controllers fabric crossbar statistics instance 0 location 0/3/CPU0
show controllers fabric crossbar statistics instance 1 location 0/3/CPU0
show interface hundredGigE0/3/0/1
show controllers hundredGigE0/3/0/1 stats
show controllers fabric fia stats location 0/3/CPU0
show controllers fabric fia drops ingress location 0/3/CPU0
show controllers fabric fia drops egress location 0/3/CPU0
show controllers fabric fia errors ingress location 0/3/CPU0
show controllers fabric fia errors egress location 0/3/CPU0
show controllers fabric fia q-depth location 0/3/CPU0
