Troubleshooting Packet Loss
The show hardware stack-unit command is intended primarily to troubleshoot packet loss.
• 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 unit 0-0 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
The show hardware stack-unit 0–11 drops [unit 0 [port 0–63]] command assists in identifying which stack unit,
port pipe, and port is experiencing internal drops (Figure 39-11) and (Figure 39-12).
