Configuring IP Source Guard on Cisco NX-OS Devices

This guide details the configuration of IP Source Guard on Cisco NX-OS devices. It begins with an overview of IP Source Guard, explaining its function as a filter that operates on a per-interface basis, allowing IP traffic only when the IP and MAC addresses match entries from the DHCP snooping binding table or static IP source entries. The document outlines licensing requirements, prerequisites, guidelines, and limitations for implementing IP Source Guard. It specifies that DHCP and DHCP snooping must be enabled prior to configuration and describes the steps to enable IP Source Guard on Layer 2 interfaces. The guide also includes procedures for adding or removing static IP source entries, configuring IP Source Guard on trunk ports, and displaying IP-MAC address bindings. Additionally, it provides commands for clearing IP Source Guard statistics and offers a configuration example to illustrate the process. The document serves as a comprehensive resource for network administrators managing IP Source Guard.
