Description
Use the port link-type command to set the link type of the current Ethernet port.
Use the undo port link-type command to restore the default link type.
By default, the link type of an Ethernet port is access.
The three types of ports can coexist on an Ethernet switch.
You can change the link type of an Ethernet port. However, you cannot change the link type of a port
directly from hybrid to trunk or vice versa. To do that, you must set the link type to access first.
Examples
# Configure GigabitEthernet 1/0/1 as a trunk port.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] interface GigabitEthernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port link-type trunk
port trunk permit vlan
Syntax
port trunk permit vlan { vlan-id-list | all }
undo port trunk permit vlan { vlan-id-list | all }
View
Ethernet port view
Parameters
vlan-id-list : VLAN range to which the trunk port will be added. vlan-id-list = [ vlan-id1 [ to
vlan-id2 ] ]&<1-10>, where, vlan-id is in the range of 1 to 4094 and can be discrete, and &<1-10> means
you can input up to ten VLAN IDs/ID ranges.
all : Adds the trunk port to all VLANs.
Description
Use the port trunk permit vlan command to assign the trunk port to the specified VLANs.
Use the undo port trunk permit vlan command to remove the hybrid port from the specified VLANs.
A trunk port can belong to multiple VLANs. When you use the command multiple times, all VLANs
specified in the commands will be allowed to pass through the port.
