DHCP Failover State

Configuration > Networking > DHCP Failover State

EdgeConnect appliances can act as a DHCP server for clients on the LAN side. DHCP failover allows redundancy by creating failover groups when two appliances are combined in an HA configuration. DHCP failover also provides stability if one EdgeConnect appliance dies by allowing the other EdgeConnect HA pair to take over as the DHCP server. To do so, the primary and secondary servers must be completely synchronized so that each server can reply on the other if one fails.

This tab displays the DHCP failover peer states of each server for troubleshooting purposes.
