Displaying Port-Based Traffic Control Settings - Cisco WS-C3550-12G Software Configuration Manual

Chapter 12 Configuring Port-Based Traffic Control
This example shows how to configure a secure MAC address on Fast Ethernet port 12 and verify the
configuration.
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# interface fastethernet0/12
Switch(config-if)# switchport mode access
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security mac-address 1000.2000.3000
Switch(config-if)# end
Switch# show port-security address

Displaying Port-Based Traffic Control Settings

The show interfaces interface-id switchport privileged EXEC command displays (among other
characteristics) the interface traffic suppression and control configuration. The show interfaces
counters privileged EXEC commands display the count of discarded packets. The show storm control
and show port-security privileged EXEC commands display those features.
To display traffic control information, use one or more of the privileged EXEC commands in
Table 12-2 Commands for Displaying Traffic Control Status and Configuration
Command
show interfaces [interface-id] switchport
show storm-control [interface-id] [broadcast |
multicast | unicast]
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

Purpose
Displays the administrative and operational status of all switching
(nonrouting) ports or the specified port, including port blocking and
port protection settings.
Displays storm control suppression levels set on all interfaces or the
specified interface for the specified traffic type or for broadcast traffic
if no traffic type is entered.
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
addresses for each interface, the number of secure MAC addresses on
the interface, the number of security violations that have occurred, and
the violation mode.
