ip dhcp snooping (interface)

Enables DHCP snooping on a VLAN.

Syntax
ip dhcp snooping
Parameters
None
Defaults
Enabled if enabled globally
Command Mode
INTERFACE VLAN
Usage Information

When you enable this feature, the switch begins to monitor all transactions between DHCP servers and DHCP clients and use the information to build the DHCP snooping binding table.

The system snoops packets from DHCP clients on the DHCP snooping-enabled VLAN and forwards the packets to all physical and port-channel interfaces of the VLAN.

The system processes DHCP server packets that are received through trusted physical interfaces and port-channel interfaces and forwards the packets to all VLAN member interfaces.

You can enable DHCP snooping globally and disable it on an interface.

This command is accessible to users with sysadmin and secadmin roles.

The no version of this command disables DHCP snooping on the interface.

Example 
OS10(conf-if-vl-4)# ip dhcp snooping
Supported Releases
10.5.0 or later or later
