Standby Use-Bia - Cisco Catalyst 6500 Series Command Reference Manual

Chapter 2 Commands for the Catalyst 6500 Series SSL Services Module

standby use-bia

To configure HSRP to use the burned-in address of the interface as its virtual MAC address instead of
the preassigned MAC address (on Ethernet and FDDI) or the functional address (on Token Ring), use
the standby use-bia command. Use the no form of this command to restore the default virtual MAC
address.
Syntax Description scope interface
Defaults
HSRP uses the preassigned MAC address on Ethernet and FDDI or the functional address on Token
Ring.
Command Modes Subinterface configuration submode

Usage Guidelines You can configure multiple standby groups on an interface when you enter the standby use-bia
command. Hosts on the interface must have a default gateway configured. We recommend that you set
the no ip proxy-arp command on the interface. We also recommend that you configure the standby
use-bia command on a Token Ring interface if there are devices that reject ARP replies with source
hardware addresses that are set to a functional address.
When HSRP runs on a multiple-ring, source-routed bridging environment and the HRSP routers reside
on different rings, configuring the standby use-bia command can prevent confusion about the routing
information field (RFI).
Without the scope interface keywords, the standby use-bia command applies to all subinterfaces on the
major interface. You cannot enter the standby use-bia command both with and without the scope
interface keywords at the same time.
Examples This example shows how to map the virtual MAC address to the virtual IP address:
ssl-proxy (config-subif)# standby use-bia
ssl-proxy (config-subif)#
OL-9105-01
standby use-bia [scope interface]
no standby use-bia
(Optional) Specifies that this command is configured only for the subinterface
on which it was entered, instead of the major interface.
Modification
Support for this command was introduced on the Catalyst 6500 series
switches.
The command mode for this command was changed from Proxy-VLAN to
Subinterface.
