Configuring the Basic Functions of an Ethernet Port

An Ethernet port on an H3C Low-End Ethernet switches can operate in one of the three link types:

l          Access: an access port can belong to only one VLAN and is generally used to connect to a PC.

l          Trunk: a trunk port can belong to multiple VLANs. It can receive/send packets of multiple VLANs and is generally used to connect to a switch.

l          Hybrid: a hybrid port can belong to multiple VLANs. It can receive/send packets of multiple VLANs and can be used to connect to either a switch or a PC.

You can add an Ethernet port to a specified VLAN. After that, the Ethernet port can forward the packets of the specified VLAN, so that the VLAN on this switch can intercommunicate with the same VLAN on the peer switch.

Networking and Configuration Requirements

l          Switch A and Switch B are connected through the trunk port Ethernet 1/0/1 on each side.

l          Specify VLAN 100 as the default VLAN of Ethernet 1/0/1.

l          Configure Ethernet 1/0/1 to permit the packets of VLAN 2, VLAN 6 through VLAN 50, and VLAN 100 to pass through.

Configuration Procedure

# Enter Ethernet port view of Ethernet 1/0/1.

<SwitchA> system-view

System View: return to User View with Ctrl+Z.

[SwitchA] interface ethernet1/0/1

# Configure Ethernet 1/0/1 as a trunk port. 

[SwitchA-Ethernet1/0/1] port link-type trunk

# Configure Ethernet 1/0/1 to permit the packets of VLAN 1 through VLAN 3, VLAN 6 through VLAN 50, and VLAN 100 to pass through.

[SwitchA-Ethernet1/0/1] port trunk permit vlan 1 to 3 6 to 50 100

# Configure VLAN 100 as the default VLAN of Ethernet 1/0/1.
