8.8 Port-based VLAN Setup

Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.
Port-based VLANs are specific only to the Switch on which they were created.
When you activate port-based VLAN, the Switch uses a default VLAN ID of 1.
You cannot change it.

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).
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 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.
