SNMP Walk Execution via Front Server from Network Intent

Network Intent currently supports Ping and Traceroute checks executed from the Front Server, but it does not provide an option to perform an SNMP walk from the Front Server to verify device reachability via SNMP. This enhancement would add an SNMP walk execution option within Network Intent, consistent with the existing Front Server-based Ping and Traceroute options. Customers troubleshooting device-down or node-down alerts would gain a more complete reachability assessment, reducing manual verification steps and improving the accuracy of automated network health checks.
