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
