CISCO-DHCP-SNOOPING-MIB
AI MIB Summary
The CISCO-DHCP-SNOOPING-MIB enables configuration and monitoring of Cisco IOS security policies that validate DHCP packet integrity and enforce per-interface binding tables to prevent rogue server attacks. It exposes operational metrics including trusted/untrusted port states, DHCP snooping binding entries, and counters for dropped packets due to security violations or malformed messages.
The MIB module is for configuration of DHCP Snooping feature. DHCP Snooping is a security mechanism which uses information gleaned from DHCP packets to provide per-interface security capabilities.
