Usage guidelines
A trunk port can carry multiple VLANs. If you execute the port trunk permit vlan command multiple times,
the trunk port allows the VLANs that are specified by vlan-id-list in each execution.
On a trunk port, only packets from the PVID can pass through untagged.
The configuration made in Layer 2 Ethernet interface view applies only to the port.
Examples
# Assign the trunk port Ethernet 2/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100.
<Sysname> system-view
[Sysname] interface ethernet 2/1
[Sysname-Ethernet2/1] port link-type trunk
[Sysname-Ethernet2/1] port trunk permit vlan 2 4 50 to 100
Related commands
port link-type
port trunk pvid
Use port trunk pvid to configure the PVID for the trunk port.
Use undo port trunk pvid to restore the default.
Syntax
port trunk pvid vlan vlan-id
undo port trunk pvid
Default
The PVID of a trunk port is VLAN 1.
Views
Layer 2 Ethernet interface view
Predefined user roles
network-admin
Parameters
vlan-id: Specifies a VLAN ID in the range of 1 to 4094.
Usage guidelines
You can use a nonexistent VLAN as the PVID for a trunk port. If you remove the PVID of a trunk port with
the undo vlan command, the setting of the PVID on the port is not affected.
The local and remote trunk ports must use the same PVID for the packets of the PVID to be transmitted
correctly.
You must configure the trunk port to allow and forward packets from the PVID by using the port trunk
permit vlan command.
The configuration made in Layer 2 Ethernet interface view applies only to the port.
Examples
# Configure VLAN 100 as the PVID of the trunk port Ethernet 2/1, and assign Ethernet 2/1 to VLAN
100.
