Description: vRtrIfDHCPRelayRxUntrustedPkts indicates the total number of untrusted packets received by the DHCP relay agent.
What is vRtrIfDHCPRelayRxUntrustedPkts?
This read-only 32-bit counter increments each time a DHCP relay agent receives a DHCP packet from a source that is not authorized or expected on that interface, such as a rogue DHCP server. It detects potential DHCP spoofing or configuration attacks. Network operators monitor this to identify untrusted DHCP sources and verify that DHCP relay security policies are properly filtering malicious or misconfigured traffic.
