Fabric OS Commands spinFab Test for Cascaded switch ISL links. Synopsis: V3.1.x spinFab [nMillionFrames [, ePortBeg[, ePortEnd[, failmode]]]] Synopsis: V4.1.x spinfab [-nmegs count][-ports list][-setfail mode] [-domain value] Availability Admin Release V3.1.x and V4.1.x Description Used to verify the intended functional operation of the ISL links between switches at the maximum speed of 2 Gbps by setting up the routing hardware such that test frames received by each E_Port are retransmitted on the same E_Port. Several frames are then sent to the neighbor port attached to each active E_Port specified. Since the default action for such frames (which never occur for normal traffic) is to route them back to the sender, the frames that are sent in this manner will circulate until the test stops them. The following conditions must be met before spinfab can execute a successful run. ■ Trunking license needs to be present for the switch. ■ Ports must be configured into 4 port trunk groups. It is recommended that Port n of a local switch is connected to port n of a remote switch. Use the switchshow command to verify that there is only 1 trunk master per quad before spinfab is run. 768 Fabric OS Version 3.1.x/4.1.x Reference Guide
