Module: CIENA-CES-DHCPV6-CLIENT-MIB
OID (symbolic): CIENA-CES-DHCPV6-CLIENT-MIB::cienaCesDhcpv6LdraUntrustedServerPortPktsRx
OID (numeric): 1.3.6.1.4.1.1271.2.1.30.1.2.4.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object specifies the number of server DHCPv6 packets dropped because they were received on untrusted server ports.
What is cienaCesDhcpv6LdraUntrustedServerPortPktsRx?
Counts server-role DHCPv6 packets dropped because they arrived on a port marked untrusted for server traffic on this VLAN. A rising value here is either evidence of a rogue/unauthorized DHCPv6 server responding on an access-side port, or the legitimate server's uplink port simply not yet marked serverTrust -- an admin needs the port context to distinguish the two. This would spike sharply if an unauthorized IPv6 router/DHCPv6 server got plugged into a subscriber-facing port on this VLAN.
