Quick Start
2.3.5 DHCP Resilience
Prerequisites
It is possible to sustain network connectivity in case of DHCP server failure. If DHCP lease re-
use is activated, the phone will keep its DHCP-based IP address even if the lease expires. To
prevent address conflicts, the phone will send ARP requests in 5 second intervals. Additionally,
it will send discovery messages periodically to obtain a new DHCP lease.
Step by Step
In the left column, select Network > IPv4 configuration. Select the check box to enable DHCP
lease reuse.
