Module: CIENA-CES-DHCP-RELAY-MIB
OID (symbolic): CIENA-CES-DHCP-RELAY-MIB::cienaCesDhcpRelayAgentL2NoTrustedServerPktDrop
OID (numeric): 1.3.6.1.4.1.1271.2.3.6.1.6.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This MIB object reports the number of DHCP packets dropped because there are no server trusted ports configured.
What is cienaCesDhcpRelayAgentL2NoTrustedServerPktDrop?
Counts DHCP packets dropped specifically because no port on this VS is currently configured as server-trusted. A rising count here is a configuration-completeness signal, not a security event -- it tells an admin that DHCP relay is enabled but nobody has designated which port faces the actual DHCP server yet, so every server-bound reply is being discarded. This counter starts climbing the moment relay is enabled on a new VS if the admin forgets to set the uplink port's trust mode to serverTrust or dualRoleTrust.
