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.
