Configuring the 100VG-AnyLAN Port Adapter

The 100VG-AnyLAN port adapter (PA-100VG) is available on Cisco 7200 series routers and on

Cisco 7500 series routers.

The PA-100VG provides a single interface compatible with and specified by IEEE 802.12 to support

100 Mbps over Category 3 or Category 5 unshielded twisted-pair (UTP) cable with RJ-45 terminators.

The PA-100VG supports 802.3 Ethernet packets and can be monitored with the IEEE 802.12 Interface

MIB.

To configure the PA-100VG port adapter, use the following commands beginning in global configuration

mode:

Note The port number for the 100VG-AnyLAN port adapter is always 0.

Configuring the PA-100VG interface is similar to configuring an Ethernet or Fast Ethernet interface. To

display information about the 100VG-AnyLAN port adapter, use the show interfaces vg-anylan EXEC

command.

Configuring Fast EtherChannel

The Fast EtherChannel feature allows multiple Fast Ethernet point-to-point links to be bundled into one

logical link to provide bidirectional bandwidth of up to 800 Mbps. Fast EtherChannel builds on

standards-based 802.3 full-duplex Fast Ethernet to provide fault-tolerant, high-speed links between

switches, routers, and servers. This feature can be configured between Cisco 7500 series routers and

Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series

Chassis Interface (RSP7000CI) or between a Cisco 7500 series router or a Cisco 7000 series router with

the RSP7000 and RSP700CI and a Catalyst 5000 switch.

Note Using the Fast EtherChannel feature on a Catalyst 5000 switch requires a hardware

upgrade. Contact your local sales representative for upgrade details.

Fast EtherChannel provides higher bidirectional bandwidth, redundancy, and load sharing. Up to four

Fast Ethernet interfaces can be bundled in a port-channel, and the router or switch can support up to four

port-channels. The Fast EtherChannel feature is capable of load balancing traffic across the Fast Ethernet

Command Purpose

Step 1

interface vg-anylan

slot/port-adapter/port

(Cisco 7500)

interface vg-anylan slot/port

(Cisco 7200)

Specifies a 100VG-AnyLAN interface and enters interface

configuration.

Step 2

ip address ip-address mask

Specifies the IP address and subnet mask to the interface.

Step 3

frame-type ethernet

Configures the frame type. Currently, only Ethernet frames are

supported. The frame type defaults to Ethernet.
