Enabling HSRP

The standby ip interface configuration command activates HSRP on the configured interface. If an IP
address is specified, that address is used as the designated address for the Hot Standby group. If no IP
address is specified, the address is learned through the standby function. You must configure at least one
routing port on the cable with the designated address. Configuring an IP address always overrides
another designated address currently in use.

shows the default HSRP configuration.
Default HSRP Configuration
HSRP can be configured on a maximum of 32 VLAN or routing interfaces.
In the procedures, the specified interface must be one of these Layer 3 interfaces:
Routed port: a physical port configured as a Layer 3 port by entering the no switchport
–
interface configuration command.
SVI: a VLAN interface created by using the interface vlan vlan_id global configuration
–
command and by default a Layer 3 interface.
Etherchannel port channel in Layer 3 mode: a port-channel logical interface created by using
–
the interface port-channel port-channel-number global configuration command and binding
the Ethernet interface into the channel group. For more information, see the
Layer 3 EtherChannels" section on page
All Layer 3 interfaces must have IP addresses assigned to them. See the
Interfaces" section on page
