Routing between VLANs
The following table defines the fields in the output of the show reserved-vlan-map command.
Assigning trunk group ports
When a “lead” trunk group port is assigned to a VLAN, all other members of the trunk group are
automatically added to that VLAN. A lead port is the first port of a trunk group port range; for
example, “1” in 1 – 4 or “5” in 5 – 8.
Refer to “Trunk group rules” on page 699 for more information.
Enable spanning tree on a VLAN
The spanning tree bridge and port parameters are configurable using one CLI command set at the
Global Configuration Level of each Port-based VLAN. Suppose you want to enable the IEEE 802.1D
STP across VLAN 3. To do so, use the following method.
NOTE
When port-based VLANs are not operating on the system, STP is set on a system-wide level at the
global CONFIG level of the CLI.
1. Access the global CONFIG level of the CLI on FESX-A by entering the following commands.
Brocade-A> enable
No password has been assigned yet...
Brocade-A# configure terminal
Brocade-A(config)#
2. Access the level of the CLI for configuring port-based VLAN 3 by entering the following
command.
Brocade-A(config)#
Brocade-A(config)# vlan 3
Brocade-A(config-vlan-3)#
3. From VLAN 3 configuration level of the CLI, enter the following command to enable STP on all
tagged and untagged ports associated with VLAN 3.
Brocade-B(config-vlan-3)#
Brocade-B(config-vlan-3)# spanning-tree
Brocade-B(config-vlan-3)#

Field Description
Reserved Purpose Describes for what the VLAN is reserved. Note that the description is for
Brocade internal VLAN management.
Default The default VLAN ID of the reserved VLAN.
Re-assign The VLAN ID to which the reserved VLAN was reassigned.

1. If you reassign a reserved VLAN without saving the configuration and
reloading the software, the reassigned VLAN ID will display in the
Re-assign column. However, the previously configured or default VLAN
ID will display in the Current column until the configuration is saved and
the device reloaded.
Current The current VLAN ID for the reserved VLAN.
