DESCRIPTION
Check this box to activate this subnet based VLAN.
Click Apply to save the changes in this part of the screen to the system's volatile
memory. The system loses these changes if it is turned off or loses power, so use the
Config Save on the navigation panel and then the Save button to save your changes
to the non-volatile memory when you are done configuring.
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 MSC assigns to frames belonging to this VLAN.
Enter up to 32 alpha numeric characters to identify this subnet based VLAN.
Click Apply to save the changes in this part of the screen to the system's volatile
memory. The system loses these changes if it is turned off or loses power, so use the
Config Save on the navigation panel and then the Save button to save your changes
to the non-volatile memory when you are done configuring.
Click New to clear the fields so you can create a new entry.
Click Cancel to change the fields back to their last saved values.
This is the index number identifying this subnet based VLAN.
This field shows the IP address of the subnet for this subnet based VLAN.
This field shows the subnet mask in bit number format for this subnet based VLAN.
