Description: This MIB object reports the number of packets that have had option 82 replaced.
What is cienaCesDhcpRelayAgentL2Option82Replaced?
Counts DHCP packets where the relay agent replaced an existing option 82 field with its own. This is the counter that confirms cienaCesDhcpRelayAgentReplaceOption82 is actively working when set to on(1) -- packets arriving with someone else's option 82 data are being overwritten rather than passed through or having a second option 82 stacked on. If a downstream device keeps inserting its own (incorrect) option 82, this counter climbing confirms the relay is correctly overwriting it each time rather than letting the bad data reach the server.
