LABEL DESCRIPTION
Active Check this box to activate this subnet based VLANs on the Switch.
DHCP-Vlan
Override 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.
Apply 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.
Active Check this box to activate the IP subnet VLAN you are creating or editing.
Name Enter up to 32 alpha numeric characters to identify this subnet based VLAN.
IP Enter the IP address of the subnet for which you want to configure this subnet based VLAN.
Mask-Bits 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).
VID 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.
Priority Select the priority level that the Switch assigns to frames belonging to this VLAN.
Add Click Add 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.
Cancel Click Cancel to begin configuring this screen afresh.
