Port-based VLAN divides the switches ports into different Virtual LAN domain groups. After setting 
up port -based VLAN, ports allocated into different VLAN groups can not access each other. This is 
like creating virtual switches that do not connect to each other.   
The VLAN initial setting page is shown as below: 
 

 

 
Of course, you need to click the Enable/Disable link text to enable/disable port-based VLAN. When 
port-based VLAN is enabled, the 802.1Q VLAN will be disabled automatically. Both port-based 
VLAN and 802.1Q VLAN can not co-exist at the same time. 
 
You can add, delete and modify port-based VLAN as required. Currently the switch supports up to 32 
port-based VLAN groups for manual entry. The next few pages will described in detail, how to 
configure port-based VLAN. 
 
NOTE: A default port-based VLAN entry (No=1) is initially created by the system. This VLAN 
entry contains all ports as member and can be regarded as a non operational VLAN, as all 
ports are in the same group and no traffic isolation exists between any two ports. If new 
port-based VLAN groups are created, then VLAN No. 1 will contain no members. Group No. 1 
is a read-only VLAN group. There are only 2 situations for this VLAN – all ports are member 
ports, or all ports are not members.
