Troubleshooting Packet Loss

The show hardware stack-unit commands are intended primarily to troubleshoot packet loss.
•
show hardware stack-unit cpu data-plane statistics
•
show hardware stack-unit cpu party-bus statistics
•
show hardware stack-unit 0-7 drops unit 0-5 port 0-49
•
show hardware stack-unit 0-7 unit 0-5 {counters | details | port-stats [detail] |
register | execute-shell-cmd | ipmc-replication | table-dump}:
•

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 0–7 drops [unit 0–5 [port 0–41]]
• Display drop counters.
show hardware stack-unit drops unit port
