COS per port.
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 cpu data-plane statistics
• show hardware stack-unit cpu party-bus statistics
• show hardware stack-unit stack-unit-number drops unit 0-1 port port-number
• show hardware stack-unit stack-unit-number stack-port 48-51
• show hardware stack-unit stack-unit-number unit 0-1 {counters | details | port-stats [detail]
| register | execute-shell-cmd | ipmc-replication | table-dump}
• show hardware {layer2| layer3} {e.g. acl |in acl} stack-unit stack-unit-number port-set 0-1
• show hardware layer3 qos stack-unit stack-unit-number port-set 0-1
•
show hardware ipv6 {e.g.-acl |in-acl} stack-unit stack-unit-number port-set-number
• show hardware system-flow layer2 stack-unit stack-unit-number port-set—number [counters]
• show hardware drops interface [range] interface
• show hardware stack-unit <id> buffer-stats-snapshot unit <id> resource x
• show hardware buffer inteface interface{priority-group { id | all } | queue { id| all} ]
buffer-info
• show hardware buffer-stats-snapshot resource interface interface{priority-group { id | all }
| queue { ucast{id | all}{ mcast {id | all} | all}
• show hardware drops interface interface
• clear hardware stack-unit stack-unit-number counters
• clear hardware stack-unit stack-unit-number unit 0-1 counters
• clear hardware stack-unit stack-unit-number cpu data-plane statistics
• clear hardware stack-unit stack-unit-number cpu party-bus statistics
• clear hardware stack-unit stack-unit-number stack-port 48-51
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 stack-unit-number drops [unit 0 [port port-number]]
• Display drop counters.
show hardware stack-unit drops unit port
• Identify which interface is experiencing internal drops.
show hardware drops interface interface
Example of show hardware drops interface
