Configuring LAN Interfaces

Configuring an Ethernet or Fast Ethernet Interface

Note If you use the full-duplexand the half-duplexcommands to change the transmission mode of the first two PA-12E/2FE interfaces (port 0 and port 1), the transmission speed of the two PA-12E/2FE interfaces automatically defaults to 100-Mbps. The first two PA-12E/2FE interfaces only operate at 10-Mbps when the interfaces are autosensing and autonegotiating the proper connection speed (10-Mbps or 100-Mbps) with an attached device.

To configure the PA-12E/2FE port adapter, perform the tasks in the following sections:

•Configuring the PA-12E/2FE Port Adapter (Required)

•Monitoring and Maintaining the PA-12E/2FE Port Adapter (Optional)

•Configuring Bridge Groups Using the 12E/2FE VLAN Configuration WebTool (Optional)

Note If you plan to use a PA-12E/2FE interface to boot from a network (using TFTP), ensure that the interface is configured for a loop-free environment, an IP address is configured for the interface’s bridge-group virtual interface, and system boot image 11.2(10)P is installed on your router (use the show version command to view your router’s system boot image).

Then, before booting from the network server, use the bridge-groupbridge-group number spanning-disabledcommand to disable the Spanning-Tree Protocol configured on the interface to keep the TFTP server from timing out and closing the session.

For detailed information about booting from a network using TFTP, loading a system image from a network server, and configuring the Spanning-Tree Protocol on your Cisco 7200 series router, refer to the PA-12E/2FE Ethernet Switch Port Adapter book that accompanies the hardware and to the Cisco IOS Bridging and IBM Networking Configuration Guide.

For information on other commands that can be used to configure a PA-12E/2FE port adapter, refer to the “Interfaces Commands” chapter in the Cisco IOS Interface Command Reference. For information on bridging, refer to the “Configuring Transparent Bridging” chapter in the Cisco IOS Bridging and IBM Networking Configuration Guide.

For PA-12E/2FE port adapter configuration examples, see the “PA-12E/2FE Port Configuration Examples” section.

Configuring the PA-12E/2FE Port Adapter

This section provides instructions for a basic configuration. You might also need to enter other configuration commands depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration commands and the configuration options available, refer to the other configuration guides in the Cisco IOS documentation set.
