Comprehensive and Detailed In-Depth
DHCP Failover states determine lease assignment:
B (NORMAL): Both peers assign from their pools—full capacity for new clients. Correct.
C (COMMUNICATIONS-INTERRUPTED): Surviving peer assigns new leases within MCLT limits. Correct.
D (PARTNER-DOWN): Single peer takes full pool, assigns new leases freely. Correct.
A (RECOVER DONE): Post-recovery state before NORMAL—typically doesn’t assign until synced, but
documentation varies. Likely incorrect here unless transitional.
Practical Example: In an INE lab, test each state, monitor new client IPs, and troubleshoot capacity
limits.
