Chapter 16 VLAN
74
Figure 16-2, below, is much like Figure 16-1, except that it contains both tagged and untagged packets on
the Ethernet side. The Loop-I 6610 assigns a default VLAN ID to untagged packets (ie.VLAN3 packets in
the diagram). The default VID is always the Port VID of the Ethernet Port.

16.2 VLAN and MAC Tables
This section is designed to be a brief overview only. If you are already familiar with VLAN and MAC tables
please proceed to section 16.3 ( VLAN Commands and Setup Instructions).
16.2.1 VLAN Table
The “show VLAN table” command can be used to access the VLAN Table. The VLAN table displays the
tagged/untagged member for each VLAN ID. There can be as many as 4094 VLAN IDs. The first one that
appears in the table is automatically generated. The others must be created. If a table has so many
created entries that it becomes unwieldy, the command “show VLAN table[Start] [End]” can be used to
display partial contents of the table. For example, “show VLAN table[1] [3]” will bring up a display of
created VLANS 1, 2 and 3..
