•

When DHCP snooping is enabled globally using the 

ip dhcp snooping

 

command, and enabled on a VLAN with this command, DHCP packet 

filtering will be performed on any untrusted ports within the VLAN as 

specified by the 

ip dhcp snooping trust

 command.

•

When the DHCP snooping is globally disabled, DHCP snooping can still 

be configured for specific VLANs, but the changes will not take effect 

until DHCP snooping is globally re-enabled.

•

When DHCP snooping is globally enabled, and then disabled on a VLAN, 

all dynamic bindings learned for this VLAN are removed from the 

binding table.

This example enables DHCP snooping for VLAN 1.
