Configuring the 12E/2FE Interfaces

PA-12E/2FE Ethernet Switch 10BASE-T and 100BASE-TX Port Adapter Installation and Configuration

6-12

Step 4 Display all bridge groups in the system and their interfaces with the show bridge group

command. Verify that the appropriate interfaces are conﬁgured for each bridge group.

Step 5 Display the routed protocol conﬁgured for an interface with the show interfaces

fastethernet or ethernet slot/interface irb command. Verify that the correct protocol is

conﬁgured for the interface.

Step 6 Display the protocols conﬁgured for the entire system and speciﬁc interfaces with the

show protocols command. If necessary, return to conﬁguration mode to add or remove

protocol routing on the system or speciﬁc interfaces.

Step 7 Display the running conﬁguration ﬁle with the show running-conﬁg command. Display

the conﬁguration stored in NVRAM using the show startup-conﬁg command. Verify

that the conﬁguration is accurate for the system and each interface.

Step 8 Display the Layer 2 learned addresses for an interface with the show pas eswitch

addresses fastethernet or ethernet slot/interface command.

If the interface is down and you conﬁgured it as up, or if the displays indicate that the hardware is

not functioning properly, ensure that the network interface is properly connected and terminated. If

you still have problems bringing up the interface, contact a customer service representative for

assistance.

The following example of the show interfaces fastethernet command shows all the information

speciﬁc to the ﬁrst 12E/2FE interface port (interface port 0) in port adapter slot 3:

Router# sh int fastethernet 3/0

FastEthernet3/0 is up, line protocol is up

Note For the Cisco 7206 router shelf, the show interfaces command requires a shelf number in the

format show interfaces type shelf number/port adapter slot/interface.
