manager backup

Configures lower priority ICX-Management IP addresses that the ICX device uses to initiate a connection with ICX-Management if higher priority IP addresses fail.
Syntax
manager backup { ip-address } [ ip-address2 ] [ ip-address3 ]
no manager backup { ip-address } [ ip-address2 ] [ ip-address3 ]
Command Default

ICX-Management IP addresses are not configured on the ICX device by default, which means the ICX device attempts to initiate a connection with ICX-Management using ICX-Management IP addresses provided through DHCP Option 43.

Parameters
ip-address
The first of the backup ICX-Management IP addresses through which the ICX device attempts to connect.
ip-address2
ICX-Management IP address through which the ICX device attempts to connect if the first backup address does not work.
ip-address3
ICX-Management IP address through which the ICX device attempts to connect if the first two backup addresses do not work.
Modes

Global configuration mode

Usage Guidelines

Use the no form of the manager backup command to remove the backup ICX-Management IP addresses. Use the no manager backup command with one IP address to remove only that address. To remove the entire list, use the no manager backup command followed by the entire list.

The ICX device attempts to connect to ICX-Management by sending a query to ICX-Management IP addresses in the following order:

  • switch registrar - IP address or fully qualified domain name (FQDN) received from the switch registrar (if enabled)
  • active-list - ICX-Management IP addresses configured on the ICX device using the manager active-list command
  • DHCP - ICX-Management IP addresses received through DHCP Option 43
  • backup-list - Backup ICX-Management IP addresses configured on the ICX device using the manager backup command

Both "active" and "backup" ICX-Management IP addresses can be configured on the ICX device. Active IP addresses are given the highest priority; backup IP addresses are lower priority and are provided for redundancy.

If the ICX-Management IP addresses are both configured on the ICX device and provided by DHCP Option 43, the configured list on the ICX device takes priority over DHCP Option 43. If none of the IP addresses in the configured list are reachable, the ICX device tries to reach the addresses received through DHCP Option 43.

Examples

The following example configures three backup ICX-Management IP addresses.

device# configure terminal
device(config)# manager backup 192.168.11.200 192.168.11.201 192.168.11.202

The following example removes a single IP address from the configured list.

device# configure terminal
device(config)# no manager backup 192.168.11.202

The following example removes the entire list of backup IP addresses.

device# configure terminal
device(config)# no manager backup 192.168.11.200 192.168.11.201 192.168.11.202
