Parameters
vlan-id-list: Specifies a space-separated list of up to 32 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 the
vlan-id2 argument must be equal to or greater than the value for the
vlan-id1 argument.
all: Specifies all VLANs. To prevent unauthorized VLAN users from accessing restricted resources
through the 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 on a trunk port,
the trunk port allows all the specified VLANs.
On a trunk port, packets only from the PVID can pass through untagged.
Examples
# Configure GigabitEthernet 1/0/1 as a trunk port, and assign it to VLAN 2, VLAN 4, and VLAN 50
through VLAN 100.
