If the default buer prole dynamic is active, Dell EMC Networking OS displays an error message instructing you to remove the default
conguration using the
no buffer-profile global command.
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 0-11 drops unit 0-0 port 0-63
•
show hardware stack-unit 0-11 stack-port 48-51
•
show hardware stack-unit 0-11 unit 0-1 {counters | details | port-stats [detail] | register |
execute-shell-cmd | ipmc-replication | table-dump}
•
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 {layer2| layer3} {e.g. acl |in acl} stack-unit 0-11 port-set 0-0
•
show hardware layer3 qos stack-unit 0-7 port-set 0-0
•
show hardware ipv6 {e.g.-acl |in-acl} stack-unit 0-11 port-set 0-0
•
show hardware system-flow layer2 stack-unit 0-11 port-set 0-0 [counters]
•

•
clear hardware stack-unit 0-11 unit 0-0 counters
•
clear hardware stack-unit 0-11 cpu data-plane statistics
•
clear hardware stack-unit 0-11 cpu party-bus statistics
•
clear hardware stack-unit 0-11 stack-port 0–63
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 0–11 drops [unit 0 [port 0–63]]
• Display drop counters.
show hardware stack-unit drops unit port
