Dell Brocade G620 Brocade 8.0.1 Fabric OS Command Reference - Page 174

configure Long Distance Fabric When this mode is set to 1, ISLs in a fabric can be up to 100 km long. The exact distance level is determined by the per-port configuration on the E_Ports of each ISL. Both E_Ports in an ISL must be configured to run the same long-distance level; otherwise, the fabric will be segmented. An Extended Fabrics license is required to set this mode. BB Credit The buffer-to-buffer (BB) credit represents the number of buffers available to attached devices for frame receipt. The range of allowed values varies depending on other system settings (see Unicast-only Operation). Refer to the Fabric OS Administrator's Guide for more information on platform-specific BB Credit limitations. Insistent Domain ID Mode When this mode is set, the switch attempts to acquire from the fabric the domain number programmed in its "Switch Fabric Settings." If the operation fails, the switch will segment from the fabric. You must disable the switch before configuring this parameter. Disable Default PortName When this mode is set, the switch does not generate a default port name. Display FDMI Host Name When this mode is set, the switch displays the FDMI Host name. By default this feature is in OFF state. Dynamic Portname When enabled, this feature dynamically assigns port name with various fields such as switch name, port type, port index, and alias name. Dynamic Portname and Display FDMI Host Name features are mutually exclusive. Remote Fosexec feature The remote fosexec configuration is bi-directional. The configuration is checked when sending any fosexec request to a remote switch and also when receiving the request from a remote switch. Thus, both the sending and receiving switched must be configured with fosexec ON. By default remote fosexec feature is in OFF state. High Integrity Fabric Mode Disables or enables the system to check for FMS mode and all existing HIF parameters present in the switch. By default this feature is in OFF state. Edge hold time Configures the maximum time a frame can wait after it is received on the ingress port and before it is delivered to the egress port. If the frame waits in the egress buffer for more than the configured hold time, the switch drops the frame, replenishes sender's credit, and increments the counters er_tx_c3_timeout and er_rx_c3_timeout on the TX and RX ports respectively. The frame-timeout indicates a slow draining or a congestion or bottleneck in the fabric. Decreasing hold time on the edge switches may reduce frame drop counts in the core switches. This parameter is stored persistently in the configuration file. You can configure edge hold time on both default and logical switch. 150 Brocade Fabric OS Command Reference 53-1004112-02
