8.8 Protocol Based VLANs

Protocol based VLANs allow you to group traffic into logical VLANs based on the protocol
you specify. When an upstream frame is received on a port (configured for a protocol based
VLAN), the Switch checks if a tag is added already and its protocol. The untagged packets of
the same protocol are then placed in the same protocol based VLAN. One advantage of using
protocol based VLANs is that priority can be assigned to traffic of the same protocol.
Protocol based VLAN applies to un-tagged packets and is applicable only
when you use IEEE 802.1Q tagged VLAN.

DESCRIPTION
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.
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 port to which this subnet based VLAN is bound.
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.
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.
Click Cancel to begin configuring this screen afresh.
This is the index number identifying this subnet based VLAN. Click on any of these
numbers to edit an existing subnet based VLAN.
This field shows whether the subnet based VLAN is active or not.
This field shows the name the 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.
This field shows the port to which this subnet based VLAN is bound.
This field shows the VLAN ID of the frames which belong to this subnet based VLAN.
This field shows the priority which is assigned to frames belonging to this subnet
based VLAN.
Click this to delete the subnet based VLANs which you marked for deletion.
Click Cancel to begin configuring this screen afresh.
