Chapter 2 Commands for the Catalyst 6500 Series SSL Services Module
standby mac-address
standby mac-address
To specify a virtual MAC address for HSRP, use the standby mac-address command. Use the no form
of this command to revert to the standard virtual MAC address (0000.0C07.ACxy).
standby [group-number] mac-address mac-address
no standby [group-number] mac-address
Syntax Description
Defaults If this command is not configured, and the standby use-bia command is not configured, the standard
virtual MAC address is used: 0000.0C07.ACxy, where xy is the group number in hexadecimal. This
address is specified in RFC 2281, Cisco Hot Standby Router Protocol (HSRP).
Command Modes Subinterface configuration submode
Command History
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-address
command 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 2-11.
group-number (Optional) Group number on the interface for which HSRP is being activated.
The default is 0.
