Use CLI for Troubleshooting

You can use CLI to provide diagnostic information.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Disable scrolling of the output display:

    terminal more disable

  3. View configuration file information:

    more WORD<1–99>

  4. Capture the output for the following command after you observe a problem with the device:

    show running-config [verbose] [module {app-telemetry | boot | cfm | cli | diag | dvr | eap | endpoint-tracking | energy-saver | fa | fhs | filter | ike | ip | ipfix | ipsec | ipv6 | iqagent | isis | i-sid | lacp | license | lldp | lst | macsec | mlt | naap | nls | ntp | ovsdb | port | qos | radius | restconf | rmon | sflow | security | slpp | smtp | spbm | stg | sys | tacacs | virtualservice | vlan | web | vxlan}]

  5. Capture the output for the following command after you observe a problem with the device:
    show tech
    Note

    Note

    show tech is an alias for show fulltech. Both commands provide the same output.
  6. Capture the output for the following commands after you observe a problem with the device:
    Note

    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]] [,...]}]

  7. Capture the output for the following command after you observe a problem with the device:

    show interfaces gigabitEthernet error [collision|ospf|verbose] [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]
