Displaying Port-Based Traffic Control Settings
To display traffic control information, use one or more of the privileged EXEC commands in
Table 17-1 Commands for Displaying Traffic Control Status and Configuration
Command
show interfaces [interface-id] switchport
show storm-control [interface-id] [broadcast |
multicast | unicast] [history]
show interfaces [interface-id] counters broadcast
show interfaces [interface-id] counters multicast
show interfaces [interface-id] counters unicast
show port-security [interface interface-id]
show port-security [interface interface-id] address Displays all secure MAC addresses configured on all switch interfaces
This is a an example of output from the show interfaces switchport privileged EXEC command:
Switch# show interfaces gigabitethernet0/2 switchport
Name:Gi0/2
Switchport:Enabled
Administrative Mode:dynamic desirable
Operational Mode:down
Administrative Trunking Encapsulation:dot1q
Negotiation of Trunking:On
Access Mode VLAN:1 (default)
Trunking Native Mode VLAN:1 (default)
Trunking VLANs Enabled:ALL
Pruning VLANs Enabled:2-1001
Protected:false
Voice VLAN:none (Inactive)

if no traffic type is entered or to display storm-control history.
Displays the storm-control broadcast suppression discard counter with
the number of packets discarded for all interfaces or the specified
interface.
Displays the storm-control multicast suppression discard counter with
the number of packets discarded for all interfaces or the specified
interface.
Displays the storm-control unicast suppression discard counter with
the number of packets discarded for all interfaces or the specified
interface.
Displays port security settings for the switch or for the specified
interface, including the maximum allowed number of secure MAC
