Module: CIENA-CES-DHCPV6-CLIENT-MIB
OID (symbolic): CIENA-CES-DHCPV6-CLIENT-MIB::cienaCesDhcpv6LdraExceededHopCountPktDrop
OID (numeric): 1.3.6.1.4.1.1271.2.1.30.1.2.4.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object specifies the number of DHCPv6 packets dropped due to hop count in the packet exceeding hop count the limit.
What is cienaCesDhcpv6LdraExceededHopCountPktDrop?
Counts DHCPv6 packets dropped because the hop count in the relay-forwarding header exceeded the protocol's allowed limit. In IPv6 DHCP relay chains, each relay agent increments a hop count field, so a rising value here suggests a relay loop or an unusually long chain of nested relay agents somewhere upstream of this VLAN. This would trigger if two relay devices were accidentally configured to relay to each other, causing hop count to climb with every bounce until it's dropped.
