DESCRIPTION
Check this box to activate this subnet based VLANs on the Switch.
When DHCP snooping is enabled DHCP clients can renew their IP address through
the DHCP VLAN or via another DHCP server on the subnet based VLAN.
Select this checkbox to force the DHCP clients in this IP subnet to obtain their IP
addresses through the DHCP VLAN.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are
done configuring.
Check this box to activate the IP subnet VLAN you are creating or editing.
Enter up to 32 alphanumeric characters to identify this subnet based VLAN.
Enter the IP address of the subnet for which you want to configure this subnet based
VLAN.
Enter the bit number of the subnet mask. To find the bit number, convert the subnet
mask to binary format and add all the 1's together. Take "255.255.255.0" for
example. 255 converts to eight 1s in binary. There are three 255s, so add three
eights together and you get the bit number (24).
Enter the ID of a VLAN with which the untagged frames from the IP subnet specified
in this subnet based VLAN are tagged. This must be an existing VLAN which you
defined in the Advanced Applications > VLAN screens.
Select the priority level that the Switch assigns to frames belonging to this VLAN.
