Installing Extended Fabrics 25 26 HP Distributed Fabrics User's Guide 6 USING EXTENDED FABRICS You can configure ports to support long-distance links through Telnet or through Web Tools. For information about using Web Tools to configure ports, see the Web Tools User's Guide. Configuring Extended Fabrics To use Extended Fabrics, you must configure each switch in the fabric to support a long-distance extended fabric. This task consists of specifying the long-distance level for each port in the switch, and then specifying the same level for each port's neighboring port (the second port in a two-port pair). If incorrectly set, the fabric segments until the configurations in each segment match. To set the long-distance fabric mode bit: 1. Enter "1" on the following line: Long Distance Fabric [0]: 27 There are three possible levels for a port: · Level 0 Reconfigures the port as a regular switch port. The number of buffers reserved for the port supports up to 10 km links. A total of 27 full-size frame buffers are reserved for the port. · Level 2 Distances up to 100 km. A total of 60 full-size frame buffers are reserved for the port. Ports are grouped into quads, each of which consists of four adjacent ports that share a common pool of frame buffers. The possible quad groupings are ports 0 to 3, 4 to 7, 8 to11, and 12 to15. Certain buffers are dedicated for each port, but others are shared among the ports. In extended fabric mode, one port is given an increase of dedicated buffers from this pool. Because the total number of frame buffers in a quad is limited, only one port in the quad can be configured for use in an extended fabric at any one time. When one port is configured as a long-distance port, the remaining ports in the quad must be configured as regular switch ports (Level 0). Accessing Through the Telnet Interface You can configure a port to support long-distance links by using the following portCfgLongDistance Telnet command.

Gateway GBIC Hardware Translative Mode ISL Isolated E_Port LIP L_Port Multicast N_Port NL_Port PLDA Interswitch Link. A port that is online but not operational between switches due to overlapping domain ID or nonidentical parameters such as E_D_TOVs. Used when multiple copies of data need to be sent to multiple designated destinations. Used to connect an equipment port to the fabric. [. . . ]
