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).
