asymmetric-lease-time (DHCP Overrides)


Hierarchy Level


Set an asymmetric lease time for an address that is sent to the DHCP client instead of the actual lease time granted by the DHCP local server. The asymmetric lease time is shorter than the granted lease. Asymmetric leases require the DHCP client to renew the lease more frequently, at shorter intervals. If the client does not renew the short lease before it expires, the address is released sooner than if the original lease had been sent to the client, conserving address resources. Although you can configure the asymmetric lease on either the DHCP relay agent or the DHCP local server, in most situations, configuring the asymmetric lease on the relay agent is more useful.
