dual-active recovery ip address
dual-active recovery ip address
To configure an IP address for the management interface when the switch is in recovery mode, use the
dual-active recovery ip address command in virtual-switch configuration submode. To remove the IP
address, use the no form of this command.
dual-active recovery [switch num] ip address ip-address ip-mask
no dual-active recovery ip address ip-address ip-mask
Syntax Description
Defaults This command has no default settings.
Command Modes Virtual switch configuration submode (config-vs-domain)
Command History
Usage Guidelines The command accepts up to three IP addresses - one for switch 1, one for switch 2 and one global IP
address. When a switch enters recovery mode, it picks up the configured switch-specific recovery IP
address for its management interface. If the switch-specific IP address is unconfigured, the global
recovery IP address is used. If neither the switch-specific nor global recovery IP addresses are
configured, the fastEthernet1 management interface on the switch has no IP address active, when the
switch enters recovery mode.
The normal IP address configured for fastEthernet1 in interface configuration mode is retained in the
configuration.
Examples The following example shows how to configure global recovery IP address:
Switch(config)# switch virtual domain domain-id
Switch(config-vs-domain)# dual-acti
ve recovery ip address 192.168.1.5 255.255.255.0
Switch(config-vs-domain)# exit
switch num (Optional) The virtual switch number of the chassis for which the IP
address must be used. If unspecified, the same IP address is used for
either switch.
ip-address Specifies an IP address.
ip-mask Specifies an IP address mask.
Release Modification
Cisco IOS XE 3.4.0SG and
15.1(2)SG
Support for this command was introduced on the Catalyst 4500 series
switch.
