H3C S7500E Series Command Reference Manual page 274

Parameters
vlan-id-list: 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. However, When GVRP is disabled on a port, you are discouraged
to configure the command on the port. This is to prevent users of unauthorized VLANs from accessing
restricted resources through 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.
Note that 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 Ethernet Interface Configuration in the Layer 2 – LAN Switching Configuration
Guide.
In Layer 2 aggregate interface view, this command applies to the Layer 2 aggregate interface and
all its member ports. After you perform the configuration, the system starts applying the
configuration to the aggregate interface and its aggregation member ports. If the system fails to do
that on the aggregate interface, it stops applying the configuration to the aggregation member
ports. If it fails to do that on an aggregation member port, it simply skips the port and moves to the
next port. For more information about Layer 2 aggregate interfaces, see Ethernet Link
Aggregation Configuration in the Layer 2 – LAN Switching Configuration Guide.

Examples
# Assign the trunk port GigabitEthernet 2/0/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/1
[Sysname-GigabitEthernet2/0/1] port link-type trunk
[Sysname-GigabitEthernet2/0/1] port trunk permit vlan 2 4 50 to 100
Please wait........... Done.
# Assign the trunk Layer 2 aggregate interface Bridge-aggregation 1 to VLAN 2, assuming that
Bridge-aggregation 1 does not have member ports.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] port trunk permit vlan 2
Please wait... Done.
# Assign the trunk Layer 2 aggregate interface Bridge-aggregation 1 to VLAN 13 and VLAN 15.
Among the member ports of the aggregation group corresponding to Bridge-aggregation 1,
GigabitEthernet 2/0/2 is an access port, and GigabitEthernet 2/0/3 is a trunk port.
