A virtual LAN (VLAN)
is a logical definition of a network work group. It is
roughly equivalent to a broadcast domain. A
VLAN interface
is your
system’s point of attachment to a given VLAN. A VLAN and a VLAN
interface are analogous to an IP subnetwork and an IP interface.
For more information about VLANs, see the
Implementation Guide
for
your system.
Menu Structure
The commands that you can use depend on the system that you have,
your level of access, and the types of modules and other hardware
options that are configured for your system. The following diagram
shows the complete list of commands for all systems. See the checklist at
the beginning of each command description in this chapter for whether
your system supports the command.
The
bridge vlan stpMode
command is available
only
when you enable
allClosed mode on the CoreBuilder
®
3500 system or the
CoreBuilder 9000 Layer 3 switching modules. The command does not
appear when you are using the default VLAN mode (allOpen) or when
you use allClosed mode on a Layer 2 system or module.
