By default, ports 0 through 23 are enabled on the switch. To enable ports 24 through 31, install a Ports on Demand license key. To enable ports 32 through 39, install another Ports on Demand license. 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 reenable the switch to activate all ports simultaneously. To install the additional port activation 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 at the following Web site: http://www.ibm.com/servers/ storage/support/san. 1. On that page, from the Product list, select your product. 2. Select Download from the Support & downloads section. 3. From the page that is generated, select License request in the Tool/utility section. 4. Follow the instructions on that page to generate the key. You can also use this site to generate other license keys for your switch. ISL Trunking groups The switch supports Interswitch Link (ISL) Trunking as a licensed feature. When this feature is enabled, you can create Trunked groups of up to 8 contiguous ports. This means that you can create up to five trunked groups that contain 8 ports each. The Fibre Channel ports on the switch are numbered from left to right and color-coded into groups of eight to indicate which ports you can combine into trunked groups. Note: 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. Supported optional features The switch supports the following optional software, which you can activate by purchasing the corresponding license key: v Extended Fabric-allows implementation of long distance dynamic (LD) and long distance static (LS) distance levels. This feature extends SAN fabrics beyond the Fibre Channel standard 10 km by optimizing the internal switch buffers to maintain performance on ISLs at distances up to 500 kilometers. v Advanced Performance Monitor-provides Performance Monitoring capability to help identify end-to-end bandwidth usage by host/target pairs and is designed to provide information for capacity planning. v Trunking Activation-designed to enable Fibre Channel packets to be efficiently distributed across multiple Inter-Switch connections (links) between two SAN b-type fabric switches, while preserving in-order delivery. ISL Trunking is supported between any of the supported 2, 4, or 8 Gbps b-type models. Both SAN b-type fabric switches must have ISL Trunking activated. v Adaptive Networking- provides a set of capability allowing high priority connections to obtain the bandwidth necessary for optimum performance, even in congested environments.
