10. Select the Save link at the bottom of the dialog, then select Yes when prompted to save the configuration
change to the startup-config file on the device's flash memory.
Enabling Port-Based VLANs
Port and protocol VLANs must first be enabled at the system (global) level before they can be configured at the
VLAN level. For details on configuring VLANs refer to "Configuring Virtual LANs (VLANs)" on page 25-1.
USING THE CLI
When using the CLI, port and protocol-based VLANs are created by entering one of the following commands at
the global CONFIG level of the CLI.
To create a port-based VLAN, enter commands such as the following:
BigIron(config)# vlan 222 by port
BigIron(config)# vlan 222 name Mktg
Syntax: vlan <num> by port
Syntax: vlan <num> name <string>
The <num> parameter specifies the VLAN ID. The valid range for VLAN IDs starts at 1 on all systems but the
upper limit of the range differs depending on the device. In addition, you can change the upper limit on some
devices using the vlan max-vlans... command. See the Foundry Switch and Router Command Line Interface
Reference.
The <string> parameter is the VLAN name and can be a string up to 16 characters. You can use blank spaces in
the name if you enclose the name in double quotes (for example, "Product Marketing".)
NOTE: The second command is optional and also creates the VLAN if the VLAN does not already exist. You
can enter the first command after you enter the second command if you first exit to the global CONFIG level of the
CLI.
USING THE WEB MANAGEMENT INTERFACE
To enable port-based VLANs on the switch or router:
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Select the box next to Port, next to Policy Based VLANs.
3. Click Apply to save the changes to the device's running-config file.
4. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device's flash memory.
Assigning IEEE 802.1q Tagging to a Port
When a port is tagged, it allows communication among the different VLANs to which it is assigned. A common
use for this might be to place an email server that multiple groups may need access to on a tagged port, which in
turn, is resident in all VLANs that need access to the server.
NOTE: Tagging is disabled by default on individual ports.
NOTE: Tagging does not apply to the default VLAN.
For details on configuring port-based VLANs refer to "Configuring Virtual LANs (VLANs)" on page 25-1.
USING THE CLI
When using the CLI, ports are defined as either tagged or untagged at the VLAN level.
