DHCPv4 Snooping
– 1121 –
ip dhcp snooping
vlan
This command enables DHCP snooping on the specified VLAN. Use the no
form to restore the default setting.
SYNTAX
[no] ip dhcp snooping vlan vlan-id
vlan-id - ID of a configured VLAN (Range: 1-4094)
DEFAULT SETTING
Disabled
COMMAND MODE
Global Configuration
COMMAND USAGE
◆ When DHCP snooping is enabled globally using the ip dhcp snooping
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 ip dhcp snooping trust 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 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
