Questions about IP source guard

1.ISG & port-channel

Where I should input the command "ip verify source dhcp-snooping-vlan", under the physical interface or port-channel interface?

2.ISG & PVLAN

   

Because I will not use IP DHCP snooping, I have to input the static ISG entry as below:

"ip source binding 1.1.1.1 1111.1111.1111 vlan xx interface g2/1"

I'm confused about the VLAN ID, it should be Primary VLAN ID or the Secondary VLAN ID???
