This page allows a user to configure detailed settings of DHCP Snooping for each port
(GE/LAG).
Any device that is not in the service provider network will be regarded as an untrusted source
(such as a customer switch). Host ports are untrusted sources. In VigorSwitch, you can assign
a source as trusted device by configuring the trust state of its connecting port.
Available settings are explained as follows:
Item Description
Ports Use the drop down list to select the port (GE1 to GE28, LAG1
to LAG8) or ports for applying DHCP snooping function.
Trust Enable – Check it to make the port(s) selected above as
trusted interface.
Verify Chaddr Enable - Check it to enable chaddr (client hardware address)
validation of GE/LAG port. All DHCP packets will be checked if
the client hardware MAC address is the same as source MAC in
Ethernet header or not. Default is disabled.
Rate Limit Input rate limitation (0~300) of DHCP packets. The unit is
“pps”. “0” means unlimited. Default is unlimited.
Apply Apply the settings to the switch.
