An NCM script to add an 'ip verify sourceguard' command to specific interfaces.The interfaces must:1) Be 'fastethernet'2) Be assigned to a given VLAN, specified by the user.Inputs are:1) Device2) VLAN whose interfaces should be modified.Use case: the NCM user would want to modify all interfaces on a switch on 'VLAN10'; they would enter '10' for the VLAN, and the script would then find all interfaces on that VLAN and add the command to each.
