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 alpha numeric characters to identify this subnet based VLAN.
Select to configure an IPv4 or IPv6 address.
Enter the IPv4 or IPv6 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 Application > VLAN screens.
Select the priority level that the Switch assigns to frames belonging to this VLAN.
