Troubleshooting Packet Loss
The show hardware stack-unit command is intended primarily to troubleshoot packet loss.
To troubleshoot packet loss, use the following commands.
show hardware stack-unit 0–5 cpu data-plane statistics
show hardware stack-unit 0–5 cpu party-bus statistics
show hardware stack-unit 0-5 drops unit 0-0 port 1–56
show hardware stack-unit 0-5 stack-port 33–56
show hardware stack-unit 0-5 unit 0-0 {counters | details | port-stats
[detail] | register | ipmc-replication | table-dump}:
show hardware {layer2| layer3} {eg acl |in acl} stack-unit 0-5 port-set 0-0
show hardware layer3 qos stack-unit 0-5 port-set 0-0
show hardware system-flow layer2 stack-unit 0-5 port-set 0-1 [counters]
clear hardware stack-unit 0-5 counters
clear hardware stack-unit 0-5 cpu data-plane statistics
clear hardware stack-unit 0-5 cpu party-bus statistics
clear hardware stack-unit 0-5 stack-port 33–56

Displaying Drop Counters

To display drop counters, use the following commands.
Identify which stack unit, port pipe, and port is experiencing internal drops.
show hardware stack-unit 0–11 drops [unit 0 [port 0–63]]
Display drop counters.
show hardware stack-unit drops unit port
Identify which interface is experiencing internal drops.
show hardware drops interface interface
