Description: Identifies the port Interface ifindex, which connected to DHCP client identified with the entry.
What is rlIpDhcpSnoopPortInterface?
This read-write InterfaceIndex identifies the switch port ifIndex connected to the DHCP client referenced by this snooping binding entry. An admin cares because it ties a learned IP/MAC binding to the specific physical port it was seen on, which downstream security features check traffic against. For example, an admin investigating a possible IP spoofing attempt would compare this field's recorded port against the port traffic is actually arriving on to detect a mismatch.
Examples
