Parameters
vlan-id-list: Specifies a list of VLANs that the trunk port(s) will be assigned to. This argument is expressed
in the format of [vlan-id1 [ to vlan-id2 ] ]&<1-10>, where vlan-id ranges from 1 to 4094 and &<1-10>
indicates that you can specify up to 10 VLAN IDs or VLAN ID ranges.
all: Permits all VLANs to pass through the trunk port(s). On GVRP-enabled trunk ports, you must configure
the port trunk permit vlan all command to ensure that the traffic of all dynamically registered VLANs can
pass through. To prevent unauthorized VLAN users from accessing restricted resources through a
GVRP-disabled port, do not user the port trunk permit vlan all command on the port.
Description
Use the port trunk permit vlan command to assign the current trunk port(s) to the specified VLAN(s).
Use the undo port trunk permit vlan command to remove the trunk port(s) from the specified VLANs.
By default, a trunk port allows only packets from VLAN 1 to pass through.
A trunk port can carry multiple VLANs. If you execute the port trunk permit vlan command multiple times,
the VLANs the trunk port carries are the set of VLANs specified by vlan-id-list in each execution.
On a trunk port, only traffic of the default VLAN can pass through untagged.
In port group view, this command applies to all ports in the port group. For more information about port
groups, see the Layer 2—LAN Switching Configuration Guide.
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.
For more information about Layer 2 aggregate interfaces, see the Layer 2—LAN Switching
Configuration Guide.
