64 CHAPTER 2: USING PORT COMMANDS Description Use the port link-type command to configure the link type of the Ethernet port. Use the undo port link-type command to restore the port as default status. By default, a port is an access port. A port on a Switch can be configured as an access port, a hybrid port, a trunk port or a fabric port. However, to reconfigure between hybrid and trunk link types, you must first restore the default, or access, link type. Example To configure the Ethernet port Ethernet1/0/1 as a trunk port, enter the following: system-view System View: return to User View with Ctrl+Z. [SW5500]interface Gigabitethernet 1/0/1 [SW5500-GigabitEthernet1/0/1]port link-type trunk port trunk permit vlan Syntax port trunk permit vlan {vlan_id_list | all} undo port trunk permit vlan {vlan_id_list| all} View Ethernet port view Parameter vlan_id: Enter a VLAN ID, or more than one VLAN ID, in the range 1 to 4094. The trunk port will be added to the specified VLANs. This can be a single VLAN, a series of individual VLANs separated by a space, or the first VLAN in a range of VLANs. If this is the first VLAN in a range use the last_vlan_id parameter to indicate the last VLAN in the range (vlan_id to last_vlan_id). You can enter up to ten vlan_id parameters at one port trunk permit vlan command. all: Enter to add the trunk port to all VLANs. Description Use the port trunk permit vlan command to add a trunk port to one VLAN, a selection of VLANs or all VLANs. Use the undo port trunk permit vlan command to remove a trunk port from one VLAN, a selection of VLANs or all VLANs. A trunk port can belong to multiple VLANs. If the port trunk permit vlan command is used many times, then the VLAN enabled to pass on trunk port is the set of these vlan_id_list. Related command: port link-type.
