NOC sees DHCP Discover from a new spine but no Offer. Which troubleshooting focus is most appropriate in a DC management context?
Select an answer to reveal the explanation.
Short Explanation
Discover with no Offer is a missing reply on the management path—scope empty, wrong VLAN, broken relay, or dead server. NOC should chase those basics before tearing down VXLAN. Overlay surgery rarely fixes a silent DHCP server.
Full Explanation
A DHCP Discover without an Offer points to scope exhaustion or mismatch, L2 domain isolation, misconfigured relay, or unreachable DHCP servers—not EVPN MAC aging or overlay rebuilds as first steps. Disabling uplinks worsens isolation. Methodically validate management-path DHCP infrastructure when new spines fail to obtain leases during ZTP.
