Supported fabric configurations

The Brocade 300 is supported as an edge device in fabrics of up to 239 switches.

Brocade 300 can be purchased with 8, 16, or 24 licensed ports. As your needs increase, you can activate unlicensed ports by

purchasing and installing the Brocade Ports on Demand (POD) optional licensed product. After it has been installed, the license appears

in the licenseShow command output as Ports on Demand license .

By default, ports 0 through 7 are enabled on the Brocade 300. To enable ports 8 through 16, install a POD license key. To enable ports

16 through 24, install another POD license.

To install a POD license, you can either use the supplied license key or generate a license key. Typically the switch is shipped with a paper

pack that specifies the transaction key to use with the Software License Keys link. Use this transaction key on the Brocade Web site at

www.brocade.com /licensekeys and follow the instructions to generate the key. You can also use this site to generate other license keys

for your switch.

After you have installed the license keys, you must enable the ports. You can do so without disrupting switch operation by using the

portEnable command on each port individually. Alternatively, you can disable and re-enable the switch to activate all ports

simultaneously.

For detailed information on enabling additional ports using the POD license, refer to the Fabric OS Administrator's Guide .

The Brocade 300 supports Interswitch Link (ISL) Trunking as a licensed feature. When this feature is enabled, you can create trunked

groups of up to eight contiguous ports. This means that you can create up to three trunked groups that contain eight ports each.

The Fibre Channel ports on the Brocade 300 are numbered from left to right and color-coded into groups of eight to indicate which

ports you can combine into trunked groups.

NOTE

Brocade ISL Trunking is optional software that allows you to create trunking groups of ISLs between adjacent switches. For

more information about trunking, refer to the Fabric OS Administrator's Guide
