Troubleshooting Tips

Edge Switch 2/24 Product Manager User Guide
Four Byte Words Rx
The number of four-byte words that the port has received.
Four Byte Words Tx
The number of four-byte words that the port has transmitted.
Offline sequences
The number of offline sequence that the port has received or transmitted.
Link resets
The number of link reset protocol frames received/transmitted by this port
from/to the attached switch. The switch transmits a link reset to initiate the
link reset protocol or recover from a link timeout. The switch receives a link
reset from an attached device if the device wishes to initiate the link reset or
recover from a link timeout.
There are not thresholds for these values. You may determine that a problem
exists by the rate that the value changes.
LIPS
The number of Loop Initialization Primitives (LIPS) generated/detected by
this port. These cause re-initialization of the port.
As a general rule, you should clear all counts after the system is stabilized.
When looking at the Performance View, roughly keep track of the time
interval when errors accumulate to judge the presence and severity of a
problem. Also, recognize that there is a link recovery hierarchy implemented
in Fibre Channel to handle some level of expected anomalies. In general, only
be concerned with error counts that increment very quickly.
