The port trunk permit vlan all command can be ineffective to super VLANs or voice VLANs. If you are
prompted with a configuration error message when using this command, use the display this command
to view the execution result.
On a trunk port, only traffic of the PVID can pass through untagged.
The configuration made in Layer 2 Ethernet interface view applies only to the port.
The configuration made in port group view applies to all ports in the port group.
The configuration made in Layer 2 aggregate interface view applies to the aggregate interface and its
aggregation member ports.
If the system fails to apply the configuration to the aggregate interface, it stops applying the
•
configuration to aggregation member ports.
If the system fails to apply the configuration to an aggregation member port, it skips the port and
•
moves to the next member port.
To prevent unauthorized VLAN users from accessing restricted resources through a port, use the port
trunk permit vlan all command with caution on the port.

Examples
# Assign the trunk port Ethernet 1/0/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100.
<Sysname> system-view
[Sysname] interface ethernet 1/0/1
[Sysname-Ethernet1/0/1] port link-type trunk
[Sysname-Ethernet1/0/1] port trunk permit vlan 2 4 50 to 100
Please wait........... Done.
# Assign the trunk Layer 2 aggregate interface Bridge-Aggregation 1 to VLAN 2.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] port link-type trunk
[Sysname-Bridge-Aggregation1] port trunk permit vlan 2
Please wait... Done.
Configuring Ethernet1/0/1... Done.
Configuring Ethernet1/0/2... Done.
Configuring Ethernet1/0/3... Done.
The output shows that Ethernet 1/0/1, Ethernet 1/0/2, and Ethernet 1/0/3 are the member ports of the
aggregation group corresponding to Bridge-Aggregation 1.
