Hello,

I understand that "ip dhcp snooping" turns on the snooping capabilities and you have to trust a link for a dhcp.

I just don't understand the ip dhcp snooping vlan ## command. can someone please explain this command.

Hi Joshua ,

Accordingly to the command reference:

"By default, the DHCP snooping feature is inactive on all VLANs. You may enable the feature on a single VLAN or a range of VLANs.

You can configure DHCP snooping for a single VLAN or a range of VLANs:

•To configure a single VLAN, enter a single VLAN number.

•To configure a range of VLANs, enter a beginning and an ending VLAN number or a dash-separated pair of VLAN numbers.

•You can enter a comma-separated list of VLAN numbers and dash-separated pairs of VLAN numbers.

Hope it helps
