NOTE:
When configuring stateful failover to support DHCP services, the address pools configured on the active
and standby servers must be consistent.

Stateful failover states
The stateful failover states include the following:
•
Silence—Indicates that the device has just started, or is transiting from synchronization state to
independence state.
•
Independence—Indicates that the silence timer has expired, but no failover link is established.
•
Synchronization—Indicates that the device has completed state negotiation with the other device
and is ready for service backup.
