• 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.

• VLAN – ID of a configured VLAN. (Range: 1-4093)
