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 stack-unit-number cpu data-plane statistics
•
show hardware stack-unit stack-unit-number cpu party-bus statistics
•
show hardware stack-unit stack-unit-number drops unit unit-number
•
show hardware stack-unit stack-unit-number unit unit-number {counters | details | port-stats
[detail] | register | ipmc-replication | table-dump}
•
show hardware {ip | ipv6 | mac} {eg-acl | in-acl} stack-unit stack-unit-number port-set 0
pipeline 0-3
•
show hardware ip qos stack-unit stack-unit-number port-set 0
•
show hardware system-flow layer2 stack-unit stack-unit-number port-set 0 {counters | pipeline
0-3}
•
show hardware drops interface interface
•
show hardware buffer-stats-snapshot resource interface interface
•
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
Displaying Drop Counters
To display drop counters, use the following commands.
•
Identify which stack unit and port pipe is experiencing internal drops.
show hardware stack-unit stack-unit-number drops [unit unit-number]
•
Identify which interface is experiencing internal drops.
show hardware drops interface interface
