Description
Configure the router to maintain, rather than log out, DHCP relay and DHCP local server based subscribers when the specified type of event occurs.
For example, by default, the router logs out DHCP subscribers
when an interface delete event occurs, such as a line card reboot
or failure. You would specify the interface-delete option
to ensure that the router maintains subscribers during line card reboots
or failures. However, this option does not maintain subscribers during
router reboots or failures.
This statement provides a global configuration for the router, which applies to all DHCP local server and DHCP relay clients in all routing instances.
The maintain-subscriber statement and remove-when-no-subscribers statement are mutually exclusive.
You cannot specify that dynamically configured VLAN interfaces are
removed when no subscribers exist when the router is also configured
to maintain subscribers.
The remaining statement is explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.
