How to view brief information about the interface status and traffic statistics

You can run the display interface brief command to view brief information about the status and configuration of an interface.

The InUti field in the command output indicates the average bandwidth usage of incoming packets on an interface in the last 300 seconds.

The OutUti field in the command output indicates the average bandwidth usage of outgoing packets on an interface in the last 300 seconds.

Inbound traffic on an interface = Interface rate x Average inbound bandwidth usage. Outbound traffic on an interface = Interface rate x Average outbound bandwidth usage. For example, the inbound traffic of GigabitEthernet0/0/5 is 320 Mbit/s (1000 Mbit/s x 32% = 320 Mbit/s) and the outbound traffic is 250 Mbit/s (1000 Mbit/s x 25% = 250 Mbit/s).
