Port Trunk Permit Vlan - HP 6125G Command Reference Manual

[Sysname-Bridge-Aggregation1] port link-type hybrid

port trunk permit vlan

Syntax
port trunk permit vlan { vlan-list | all }
undo port trunk permit vlan { vlan-list | all }
View
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 ] ]&<1- 1 0>, where vlan-id1 and vlan-id2 represent VLAN IDs and each range from 1 to 4094
and &<1- 1 0> 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.
