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 range from 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 that the specified VLANs already exist.
all
: Permits all VLANs to pass through the trunk ports.

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 on 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 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.
