Using CLI for Troubleshooting
You can use CLI to provide diagnostic information.
Procedure
-
Capture the output for the following
command after you observe a problem with the device:
show tech
Note
show tech is an alias for show fulltech. Both commands provide the same output. -
Capture the output for the following
commands after you observe a problem with the device:
Note
The show interfaces gigabitEthernet statistics rmon command displays information only if you previously configured rmon stats or rmon history.
-
show interfaces gigabitEthernet statistics <dhcp-relay [vrf WORD<1–16>][vrfids WORD<0–512>] [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]
-
show interfaces gigabitEthernet statistics lacp [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]
-
show interfaces gigabitEthernet statistics rate—limiting [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]
-
show interfaces gigabitEthernet statistics rmon [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}
-
show interfaces gigabitEthernet statistics verbose [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]
-
show interfaces gigabitEthernet statistics vlacp [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]
-
