What is tmnxVRtrDHCPSuspiciousPcktRcvd?
This notification (trap) is sent when a DHCP packet is received with suspicious or malformed content, indicating a possible DHCP-based attack or misconfigured DHCP client.

Network security teams use this alert to detect DHCP-based attacks, investigate compromised clients, and respond to configuration errors.
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::tmnxVRtrDHCPSuspiciousPcktRcvd snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6527.3.1.3.3.0.14
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
