Parameters
vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN ID or a
range of VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The
value for vlan-id2 must be equal to or greater than the value for vlan-id1.
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 allow multiple VLANs. If you execute this command multiple times, the VLANs that the
trunk port allows are the union of the VLANs specified by vlan-id-list in each execution.
On a trunk port, only packets from the PVID can pass through untagged.
Examples
# Configure GigabitEthernet 2/1/1 as a trunk port, and assign the port to VLAN 2, VLAN 4, and VLAN
50 through VLAN 100.
