1-11DescriptionUse the port link-type command to set the link type of the current Ethernet port.Use the undo port link-type command to restore the default link type.By default, the link type of an Ethernet port is access.The three types of ports can coexist on an Ethernet switch.You can change the link type of an Ethernet port. However, you cannot change the link type of a portdirectly from hybrid to trunk or vice versa. To do that, you must set the link type to access first.Examples# Configure GigabitEthernet 1/0/1 as a trunk port. system-viewSystem View: return to User View with Ctrl+Z.[Sysname] interface GigabitEthernet 1/0/1[Sysname-GigabitEthernet1/0/1] port link-type trunkport trunk permit vlanSyntaxport trunk permit vlan { vlan-id-list | all }undo port trunk permit vlan { vlan-id-list | all }ViewEthernet port viewParametersvlan-id-list: VLAN range to which the trunk port will be added. vlan-id-list = [ vlan-id1 [ tovlan-id2 ] ]&<1-10>, where, vlan-id is in the range of 1 to 4094 and can be discrete, and &<1-10> meansyou can input up to ten VLAN IDs/ID ranges.all: Adds the trunk port to all VLANs.DescriptionUse the port trunk permit vlan command to assign the trunk port to the specified VLANs.Use the undo port trunk permit vlan command to remove the hybrid port from the specified VLANs.A trunk port can belong to multiple VLANs. When you use the command multiple times, all VLANsspecified in the commands will be allowed to pass through the port.Related commands: port link-type.Examples# Assign the trunk port GigabitEthernet 1/0/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100. system-viewSystem View: return to User View with Ctrl+Z.[Sysname] interface GigabitEthernet 1/0/1[Sysname-GigabitEthernet1/0/1] port link-type trunk[Sysname-GigabitEthernet1/0/1] port trunk permit vlan 2 4 50 to 100
