tmnxVRtrDHCP6IllegalClientAddr
Module: ALCATEL-IND1-TIMETRA-VRTR-MIB
OID (symbolic): ALCATEL-IND1-TIMETRA-VRTR-MIB::tmnxVRtrDHCP6IllegalClientAddr
OID (numeric): 1.3.6.1.4.1.6527.3.1.3.3.0.25
Node type: NOTIFICATION-TYPE
Description: The tmnxVRtrDHCP6IllegalClientAddr notifications is generated when an incoming message is dropped because the client's source IP does not match the subnet of the incoming interface.
What is tmnxVRtrDHCP6IllegalClientAddr?
This notification is triggered when a DHCPv6 server detects and drops an incoming message because the client's source IP address does not belong to the subnet of the incoming interface. The event helps operators identify misconfigured clients, network routing loops, or potential attacks where traffic is arriving from unexpected addresses. Detection of this condition is valuable for diagnosing IPv6 network topology mismatches.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' ALCATEL-IND1-TIMETRA-VRTR-MIB::tmnxVRtrDHCP6IllegalClientAddr snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6527.3.1.3.3.0.25
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
