Syntax
port trunk permit vlan { vlan-list | all }
undo port trunk permit vlan { vlan-list | all }
Default
A trunk port allows only packets from VLAN 1 to pass through.
Views
Ethernet interface view, port group view, Layer 2 aggregate interface view
Default command level
2: System level
Parameters
vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN ID or a
range of VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The
value for vlan-id2 must be equal to or greater than the value for vlan-id1. Make sure the specified VLANs
already exist.
all: Permits all VLANs to pass through the trunk ports.
Usage guidelines
A trunk port can allow multiple VLANs. If you execute the port trunk permit vlan command multiple times,
the trunk port allows the set of VLANs specified by vlan-list in each execution.
On a trunk port, only traffic of the PVID can pass through untagged.
To prevent unauthorized VLAN users from accessing restricted resources, use the port trunk permit vlan
all command with caution.
The configuration made in 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.
Examples
# Assign the trunk port Ten-GigabitEthernet 1/0/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN
100.
<Sysname> system-view
[Sysname] interface Ten-GigabitEthernet1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] port link-type trunk
[Sysname-Ten-GigabitEthernet1/0/1] 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
