Assigning a trunk port to a VLAN
A trunk port supports multiple VLANs. You can assign it to a VLAN in interface view.
When you assign a trunk port to a VLAN, follow these restrictions and guidelines:
To change the link type of a port from trunk to hybrid or vice versa, set the link type to access first.
To enable a trunk port to transmit packets from its PVID, you must assign the trunk port to the PVID by using the port trunk permit vlan command.
To assign a trunk port to one or multiple VLANs:
Step | Command | Remarks |
|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | Enter Layer 2 Ethernet interface view:interface interface-type interface-number Enter Layer 2 aggregate interface view:
interface bridge-aggregation interface-number Enter S-channel interface view:interface s-channel interface-number.channel-id Enter S-channel aggregate interface view:interface schannel-aggregation interface-number:channel-id
| The configuration made in Layer 2 Ethernet interface view applies only to the port. 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 an aggregation member port, it skips the port and moves to the next member port. If the system fails to apply the configuration to the aggregate interface, it stops applying the configuration to aggregation member ports. The configuration made in S-channel interface view or S-channel aggregate interface view applies only to the interface. For more information about S-channel interfaces and S-channel aggregate interfaces, see EVB Configuration Guide.

3. Configure the link type of the port as trunk. | port link-type trunk | By default, all ports are access ports. |
4. Assign the trunk port to the specified VLANs. | port trunk permit vlan { vlan-id-list | all } | By default, a trunk port permits only VLAN 1. |
5. (Optional.) Configure the PVID of the trunk port. | port trunk pvid vlan vlan-id | The default setting is VLAN 1. |
