Port Trunk Permit Vlan - HP 12500 Series Command Reference Manual

Usage guidelines
To change the link type of a port from trunk to hybrid or vice versa, first set the link type to access.
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.
Examples
# Configure GigabitEthernet 3/0/1 as a trunk port.
<Sysname> system-view
[Sysname] interface GigabitEthernet 3/0/1
[Sysname-GigabitEthernet3/0/1] port link-type trunk

port trunk permit vlan

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.
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
Layer 2 Ethernet interface view, Layer 2 aggregate interface view
Predefined user roles
network-admin
mdc-admin
Parameters
vlan-list: Specifies a list of VLANs in the format of vlan-list = { vlan-id1 [ to vlan-id2 ] }&<1-10>,
where vlan-id1 and vlan-id2 each are in the range of 1 to 4094, vlan-id2 cannot be smaller than
vlan-id1, and &<1-10> indicates that you can specify up to 10 vlan-id1 [ to vlan-id2 ] parameters.
all: Permits all VLANs to pass through the trunk ports. To prevent unauthorized VLAN users from
accessing restricted resources through a port, use the port trunk permit vlan all command with
caution.
Usage guidelines
A trunk port can carry multiple VLANs. If you execute the port trunk permit vlan command
multiple times, the trunk port allows the VLANs that are specified by vlan-list in each execution.
On a trunk port, only packets from the PVID can pass through untagged.
The configuration made in Layer 2 Ethernet interface view applies only to the port.
