When DHCP snooping is enabled globally on the switch, and enabled on
the specified VLAN, DHCP packet filtering will be performed on any
untrusted ports within the VLAN.
•
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 DHCP snooping is then
disabled on a VLAN, all dynamic bindings learned for this VLAN are
removed from the binding table.
