VLAN Names
Summit 300-48 Switch Software User Guide 69
The server connected to port 1:16 on system 1 has a NIC that supports 802.1Q tagging.
The server connected to port 1:16 on system 1 is a member of both VLAN Marketing and VLAN
Sales.
All other stations use untagged traffic.
As data passes out of the switch, the switch determines if the destination port requires the frames to be
tagged or untagged. All traffic coming from and going to the server is tagged. Traffic coming from and
going to the trunk ports is tagged. The traffic that comes from and goes to the other stations on this
network is not tagged.
Mixing Port-Based and Tagged VLANs
You can configure the switch using a combination of port-based and tagged VLANs. A given port can
be a member of multiple VLANs, with the stipulation that only one of its VLANs uses untagged traffic.
In other words, a port can simultaneously be a member of one port-based VLAN and multiple
tag-based VLANs.
NOTE
For the purposes of VLAN classification, packets arriving on a port with an 802.1Q tag containing a
VLANid of zero are treated as untagged.
VLAN Names
Each VLAN is given a name that can be up to 32 characters. VLAN names can use standard
alphanumeric characters. The following characters are not permitted in a VLAN name:
Space
Comma
Quotation mark
VLAN names must begin with an alphabetical letter. Quotation marks can be used to enclose a VLAN
name that does not begin with an alphabetical character, or that contains a space, comma, or other
special character.
VLAN names are locally significant. That is, VLAN names used on one switch are only meaningful to
that switch. If another switch is connected to it, the VLAN names have no significance to the other
switch.
NOTE
You should use VLAN names consistently across your entire network.
Default VLAN
The switch ships with one default VLAN that has the following properties:
The VLAN name is default.
It contains all the ports on a new or initialized switch.
The default VLAN is untagged on all ports. It has an internal VLANid of 1.
