Usage Guidelines This command cannot be used on a Token Ring interface.

You can use HSRP to help end stations locate the first-hop gateway for IP routing. The end stations are configured with a default gateway. However, HSRP can provide first-hop redundancy for other protocols. Some protocols, such as Advanced Peer-to-Peer Networking (APPN), use the MAC address to identify the first hop for routing purposes. In this case, it is often necessary to be able to specify the virtual MAC address; the virtual IP address is unimportant for these protocols. Use the standby mac-addresscommand to specify the virtual MAC address.

The specified MAC address is used as the virtual MAC address when the router is active.

This command is intended for certain APPN configurations. The parallel terms are shown in Table 3-11.
