This chapter describes the advanced features offered by your switch.
Port-Based VLAN
The main purpose of VLAN is security, to prevent HomePNA user to access each other directly in the switch system.
Only the ports within the same VLAN group can access each other directly.
Default VLAN Configuration
Refer to
Figure 3
in Chapter 2, the cascaded Ethernet link acts as a traffic trunk to aggregate all HomePNA port traffic.
The straightforward VLAN configuration should let each HomePNA port (1 to 14) can communicate with the trunk for
LAN/WAN connectivity, but can't communicate with each other directly. In this configuration, Port E1 acts as
Trunk
Link
port; Port E2 gathers the traffic from other cascaded switch
Up-Link
port. The following figure shows the data
flow of default Port-Based VLAN in XL-HB14128M,
The default Port-Based VLAN configuration in the switch XL-HB14128M allows each HomePNA user to group with
port E1 only. For each HomePNA user, to access the main Ethernet trunk E1 is allowed, to access other user (port 1 to
port 14, cascaded users on port E2) is forbidden. HomePNA port (1 to 14) and port E2 aren't within the same VLAN
group. Only port 1 to port 14 and port E1 are allowed to access XL-HB14128M for Remote Configuration.
Close VLAN
If you wish to get ride of the VLAN restriction, users locate in the same LAN can access each other freely and make the
switch work as a standard switch. Adopt Tag VLAN mode and set each port with the same VID.
Tag VLAN
Please refer 802.1Q for Tag VID operation and 802.1P for Tag Priority operation. The switch can accept and forward
tagged packet with the matched VID, it can also tag the untagged packet with default VID and Priority.
Each HomePNA port (1 to 14) should be assigned a unique VID. Packets from port E1/E2 trunk with the matched VID
