Command Usage

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.
