Configure Switch Features Chapter 7
Virtual Local Area Networks
(VLANs) A VLAN is a logical segment of network users and resources grouped by
function, team, or application. This segmentation is without regard to the
physical location of the users and resources. For example, VLANs can be based
on the departments in your company or by sets of users who communicate
mostly with each other.
The switch ships with a default VLAN to which each switch port initially
belongs. The switch supports a maximum of 255 VLANs, including the default
VLAN.
Every VLAN has a name and ID number. The default VLAN is named default.
The ID can be from 1...1001 and 1005...4094, where 1 is the default ID. To
create a VLAN, you must give the VLAN a name and a unique ID number.
You can modify the name of a VLAN but not its number. You cannot rename
or delete the default VLAN.
You can assign switch ports to either the default VLAN or to VLANs that you
have created.
The default VLAN alone can be sufficient based on the size and requirements
of your network. We recommend that you first determine your VLAN needs
before creating VLANs.
With custom Smartports, you can specify the type of VLAN you want to
implement on that port. The custom Smartports feature is not available on
Stratix 8000/8300 switches.
The default VLAN is also the management VLAN. After the initial setup, you
can create VLANs and designate any VLAN on the switch as the management
VLAN. The management VLAN provides administrative access to the switch.
You must assign one of the switch ports to the management VLAN.
Otherwise, you do not have administrative access to the switch. Initially, all
ports are assigned to the management VLAN.
You can assign all ports, regardless of their Smartport role, to the default
VLAN (default).
IMPORTANT Changes to VLAN assignments on a port with Network Address Translation
(NAT) can break existing NAT configurations. Review your NAT configurations
to make sure VLAN assignments are correct.
