Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
show interfaces
show interface s
To display traffic on a specific interface, use the show interfaces command.
show interfaces [{{fasteth ern et mod/interface-number} | {gigabitethernet
mod/interface-number} | {tengigabitethernet mod/interface-number} | {null
interface-number} | vlan vl an_id} | st atus}]
Syntax Description
Defaults This command has no default settings.
Command Modes Privileged EXEC mode
Usage Guidelines The statistics are collected per VLAN for Layer 2 switched packets and Layer 3 switched packets. The
statistics are available for both unicast and multicast. The Layer 3 switched packet counts are available
for both the ingress and egress direction s. The per-VLAN stat istics are updated every 5 second s.
In some cases, the duplex mode that is displayed by the show interfaces command is different than that
displayed by the show running-config command. The duplex mode that is displayed in the show
interfaces command is the actual duplex mode that the interface is runn ing. The show interfaces
command shows the operating mode for an interface, but the show running-config command shows the
configured mode for an interface.
If you do not enter any keywords, all counters f or all modules are displa yed.
