Comprehensive and Detailed In-Depth

DHCP Failover in NIOS ensures redundancy, and its status reflects operational health:

Degraded Status: Not an official NIOS failover state (e.g., NORMAL, COMMUNICATIONS-

INTERRUPTED, PARTNER-DOWN). Likely a misnomer for a partial issue (e.g., COMMUNICATIONS-

INTERRUPTED or high lease usage). Even in such states, DHCP service continues:

Clients renew leases from the surviving peer.

New leases are issued within limits (e.g., MCLT).

Why False: "Not functioning" implies total failure, but failover design ensures partial service persists

unless both peers are down (e.g., HARDWARE-FAILURE state). A degraded-like condition doesn’t stop

DHCP entirely.

Practical Example: In an INE lab, you’d simulate a peer losing sync (COMMUNICATIONS-

INTERRUPTED), verify clients still get IPs, and troubleshoot via DHCP logs, proving service continuity.
