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
•

•

•

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
