Check the traffic report, which may indicate that one or more MSDL
ports are handling excessive traffic.
By disabling each port, identify the port with too much traffic and allow
the remaining ports to operate normally. Refer to

threshold or detecting self-test failure, place the MSDL in the manually
disabled state with the DIS MSDL x command and follow the steps in
"Previously operating MSDL cards" (page
