[Sysname-Bridge-Aggregation1] port link-type hybrid port trunk permit vlan Syntax port trunk permit vlan { vlan-list | all } View undo port trunk permit vlan { vlan-list | all } Layer 2 Ethernet interface view, Layer 2 aggregate interface view Default level 2: System level Parameters vlan-list: Specifies a list of VLANs that the trunk ports will be assigned to, in the format of [ vlan-id1 [ to vlan-id2 ] ]&, where vlan-id1 and vlan-id2 represent VLAN IDs and each range from 1 to 4094 and & indicates that you can specify up to 10 vlan-id1 [ to vlan-id2 ] parameters. The vlan-id2 argument cannot be smaller than the vlan-id1 argument. all: Permits all VLANs to pass through the trunk ports. Description Use port trunk permit vlan to assign the trunk ports to the specified VLANs. Use undo port trunk permit vlan to remove the trunk ports 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 trunk port carries the set of VLANs specified by vlan-list in each execution. The port trunk permit vlan all command can be ineffective to 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 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. Related commands: port link-type. Examples # Assign the trunk port GigabitEthernet 1/0/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100. system-view [Sysname] interface gigabitethernet 1/0/1 148
