VLAN 1 is the default untagged VLAN, including all interfaces of switch and using Hybrid mode. 
VLAN 1 is a default untagged VLAN, including all the interfaces on the switch and using Hybrid mode. 
When Eth-Trunk is used, the VLAN attribute of Eth-Trun interface will follow the principles below: 
1)If Eth-Trunk is created, the VLAN attribute of Eth-Trunk interface is set as default value; 
2)If added to Eth-Trunk, the interface will be not displayed in VLAN interface list; 
3)If removed from Eth-Trunk,the VLAN attribute of original interface will recover. 
Edit VLAN Attribute based on Interface or Interface Range 
Step 1  Click Service Management > VLAN > Interface, to open a page as shown in Fig.5-3. 
Step 2  Choose the check box in the left-hand column of the interface to be edited, and then click 
Configure button to modify the VLAN attribute of interface. The configuration page is shown 
as the figure below.

Step 3  Modify corresponding configuration item, the parameters are as shown in Fig.5-2. 
Step 4  After configuration, click Apply button to apply all the changes made.

5.2 MAC VLAN 
MAC VLAN is another partition method of VLAN, which defines the VLAN membership 
according to the source MAC address of message and sends the specified message marked 
with VLAN Tag. If the interface uses MAC VLAN partition mechanism, it will take the 
following methods when the message arrives: 
  The source MAC will try to match the MAC-VLAN entry if the received message is 
untagged or priority tagged. If the match succeeds, the message will be tagged with 
specified VLAN ID in table. If the match fails, the message will be matched 
according to other principles.
