DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
Default
By default, the station move is permitted.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
When DHCP snooping station move is enabled, the dynamic DHCP snooping binding entry with the
same VLAN ID and MAC address on the specific port can move to another port if it detects that a new
DHCP process belong to the same VLAN ID and MAC address.
Example
This example shows how to disable the roaming state.
Switch# configure terminal
Switch(config)# ip dhcp snooping
Switch(config)# ip dhcp snooping vlan 10
Switch(config)# ip dhcp snooping station-move deny
Switch(config)#
18-12 ip dhcp snooping verify mac-address
This command is used to enable the verification that the source MAC address in a DHCP packet
matches the client hardware address. Use the no form of this command to disable the verification of
the MAC address.
ip dhcp snooping verify mac-address
no ip dhcp snooping verify mac-address
Parameters
None.
Default
By default, this option is enabled.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The DHCP snooping function validates the DHCP packets when they arrive at the port on the VLAN
that is enabled for DHCP snooping. By default, DHCP snooping will verify that the source MAC
address in the Ethernet header is the same as the DHCP client hardware address to pass the
validation.
Example
This example shows how to enable the verification that the source MAC address in a DHCP packet
matches the client hardware address.
