crossPortTest V3.1.x: SwitchEnable and SwitchDisabled Mode / V4.1.x: SwitchOnline and SwitchOffline Mode The crossPortTest command can be executed when the switch is enabled/online or disabled/offline. In SwitchEnabled/SwitchOnline mode (where the switch is enabled prior to executing the crossPortTest command) only ports which are cable loopbacked to ports in the same switch are tested. Ports connected outside of the switch are ignored. To run the crossPortTest command successfully the test must find at least one port (lb_mode = 1, this is the default) or two ports (lb_mode = 0) cable loopbacked to each other. If this criteria is not met, one of the following messages is displayed: Need at least one port(s) connected to run this test Need at least two port(s) cross-connected to run this test In SwitchDisabled/SwitchOffline mode (when the switch is disabled prior to executing the crossPortTest command) all ports are assumed to be cable loopbacked to different ports in the same switch. If one or more ports are not connected, the test aborts. The test determines which port is connected to which port transmitting frames. If any ports are not properly connected (improperly seated SFPs or cables, bad SFPs or cables, or improper connection or improper connection of SWL to LWL), the following message is displayed: One or more ports is not active, please double check fibres on all ports. V3.1.x: singlePortAlso Mode The singlePortAlso mode is specified by executing crossporttest command with the singleportalso operand specified as a value of 1. For example: switch:admin> crossporttest 100, 1 In this mode, crossporttest enables a port to be cable loopbacked to itself (port M is connected to port M) in addition to the cross connection supported (port M is connected to port N). This can be used to isolate bad ports. Fabric OS Version 3.1.x/4.1.x Reference Guide 165
