Quidway S6500 Series Ethernet Switches
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.
1.2.13 Set the Default VLAN ID for the Ethernet Port
Since the access port can only be included in one VLAN only, its default VLAN is the
one to which it belongs. The hybrid port and the trunk port can be included in several
VLANs, 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.
Table 1-14 Set the default VLAN ID for the Ethernet port
Set the default VLAN ID for the hybrid port.
Set the default VLAN ID for the trunk port
Restore the default VLAN ID of the hybrid port
to the default value
Restore the default VLAN ID of the trunk port
to the default value
Note that to guarantee the proper packet transmission, the default VLAN ID of local
hybrid port or Trunk port should be identical with that of the hybrid port or Trunk port on
the peer switch.
By default, the VLAN of hybrid port and trunk port is VLAN 1 and that of the access port
is the VLAN to which it belongs.
1.2.14 Set the VLAN VPN Feature
VLAN Tag consists of 12 bits (defined by IEEE802.1Q), so Ethernet Switches can
support up to 4k VLANs. In networking, especially in MAN (Metropolitan Area Network),
a large numbers of VLANs are required to segment users. In this case, 4k VLANs are
not enough.
