Command Usage
•
When DHCP snooping enabled globally using the
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
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 DHCP snooping is then disabled on a specific
VLAN, all dynamic bindings learned for this VLAN are removed from the binding table.
Example
This example enables DHCP snooping for VLAN 1.
Console(config)#ip dhcp snooping vlan 1
Console(config)#
