Configuring LAN Interfaces

Configuring an Ethernet or Fast Ethernet Interface

To configure the interfaces on the PA-12E/2FE port adapter, use the following commands in global configuration mode:

 

Command

Purpose

Step 1

 

 

bridge bridge-groupprotocol ieee

Specifies the type of Spanning-Tree Protocol.

 

 

The PA-12E/2FE port adapter supports DEC and IEEE Spanning-Tree

 

 

Protocols; however, we recommend using the IEEE protocol when

 

 

configuring bridge groups.

Step 2

 

 

interface fastethernet slot/port

Enters the interface you want to configure.

 

(ports 0 and 1)

 

 

interface ethernet slot/port

 

 

(ports 2 through 13)

 

Step 3

 

 

bridge-group bridge-group

Assigns a bridge group to the interface.

Step 4

 

 

cut-through [receive transmit]

(Optional) Configures the interface for cut-through switching technology.

 

 

The default is store-and-forward (that is, no cut-through).

Step 5

 

 

full-duplex

(Optional) Configures the transmission mode for full-duplex, if an attached

 

 

device does not support autosensing or autonegotiation. The default is

 

 

half-duplex.

Step 6

 

 

no shutdown

Restarts the interface.

Step 7

 

 

exit

Returns to configuration mode.

Step 8

 

 

 

Repeat Steps 1 through 7 for each interface.

Step 9

 

 

copy system:running-config

Saves the new configuration to memory.

 

nvram:startup-config

 

 

 

 

To enable integrated routing and bridging on the bridge groups, use the following commands beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

bridge irb

Enables integrated routing and bridging.

Step 2

 

 

interface bvi bridge-group

Enables a virtual interface on a bridge group.

Step 3

 

 

ip address address mask

Assigns an IP address and subnet mask to the bridge-group virtual

 

 

interface.

Step 4

 

 

no shutdown

Restarts the interface.

Step 5

 

 

exit

Returns to configuration mode.

Step 6

 

 

 

Repeat Steps 1 through 5 for each bridge group.

Step 7

 

 

bridge bridge-group route

Specifies the protocol for each bridge group.

 

protocol

 

Step 8

 

 

exit

Exits configuration mode.

Step 9

 

 

copy system:running-config

Saves the new configuration to memory.

 

nvram:startup-config
