Switch 7700 Configuration Guide

32 CHAPTER 2: PORT CONFIGURATION
Adding the Ethernet Port to a VLAN
The following commands are used for adding an Ethernet port to a specified
VLAN. The access port can only be added to one VLAN, while the hybrid and trunk
ports can be added to multiple VLANs.
Perform the following configuration in Ethernet port view.
Note: The access port shall be added to an existing VLAN other than VLAN 1. The
VLAN to which Hybrid port is added must have been existed. The one to which
Trunk port is added cannot be VLAN 1.
After adding the Ethernet port to specified VLANs, the local port can forward
packets of these VLANs. The hybrid and trunk ports can be added to multiple
VLANs, thereby implementing the VLAN intercommunication between peers. For
the hybrid port, you can configure to tag some VLAN packets, based on which the
packets can be processed differently.
Setting the Default VLAN ID for Ethernet Port
Since the access port can only be included in one VLAN, its default VLAN is the
one to which it belongs. The hybrid port and the trunk port can be included in
several VLANs, however, it is necessary to configure the default VLAN ID. If the
default VLAN ID has been configured, the packets without VLAN Tag will be
forwarded to the port that belongs to the default VLAN. When sending the
packets with VLAN Tag, if the VLAN ID of the packet is identical to the default
VLAN ID of the port, the system will remove VLAN Tag before sending this packet.
Perform the following configuration in Ethernet port view.
