undo shutdown 

 

Shutting down or bringing up a VLAN interface has no effect on the UP/DOWN status of 

the Ethernet ports in this VLAN. 

By default, when all the Ethernet ports in a VLAN are in the DOWN state, this VLAN 

interface is also DOWN. When there are one or more Ethernet ports in the UP state, 

this VLAN interface is also UP. 

You can use the following commands to add the Ethernet ports to a VLAN. 

Perform the following configuration in VLAN view. 

Table 8-5 Add Ethernet ports to a VLAN 

Add Ethernet ports to a VLAN 

port interface_list 

Remove Ethernet ports from a VLAN 

undo port interface_list 

 

By default, the system adds all the ports to a default VLAN whose ID is 1. 

Note that you can add/remove the trunk and Hybrid ports to/from a VLAN by the 

port/undo port commands in Ethernet port view, but not in VLAN view.
