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

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
