LABEL | DESCRIPTION |
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 |

|
Index | This is the index number identifying this subnet based VLAN. Click on any of these |
| numbers to edit an existing subnet based VLAN. |
|
|
Active | This field shows whether the subnet based VLAN is active or not. |
|
|
Name | This field shows the name the subnet based VLAN. |
|
|
IP | 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. | |
|
|
VID | This field shows the VLAN ID of the frames which belong to this subnet based VLAN. |
|
|
Priority | This field shows the priority which is assigned to frames belonging to this subnet |
| based VLAN. |

Delete | Click this to delete the subnet based VLANs which you marked for deletion. |

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.
