R3303-HP HSR6800 Routers Layer 2 - LAN Switching Command Reference

108
Default
A trunk port allows only packets from VLAN 1 to pass through.
Views
Ethernet interface view, port group view, Layer 2 aggregate interface view
Default command 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 ] }&<1-10>, where vlan-id1 and vlan-id2 represent VLAN IDs and each in the range of 1 to
4094, vlan-id2 must be no smaller than vlan-id1, and &<1-10> indicates that you can specify up to 10
VLAN IDs or VLAN ID ranges. Make sure the specified VLANs already exist.
all: Permits all VLANs to pass through the trunk ports.
Usage guidelines
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 super VLANs or 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.
To prevent unauthorized VLAN users from accessing restricted resources, use the port trunk permit vlan
all command with caution.
The configuration made in Ethernet interface view applies only to the port.
The configuration made in port group view applies to all ports in the port group.
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
# Assign the trunk port GigabitEthernet 4/0/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100.
<Sysname> system-view
[Sysname] interface GigabitEthernet 4/0/1
[Sysname-GigabitEthernet4/0/1] port link-type trunk
[Sysname-GigabitEthernet4/0/1] 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.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] port link-type trunk
[Sysname-Bridge-Aggregation1] port trunk permit vlan 2
Please wait... Done.
