(saved on the switch with pre-Fabric OS 6.2.0 code) is merged with a switch with the same alias
member WWN in lower case characters, the merge fails, because the switches do not recognize
these zoning configurations as being the same. For more information and workaround solutions,
see the latest Fabric OS Administrator Guide.
Fabric Watch
Core Blade status reporting modification
Fabric Watch has been modified so that Core blade status reporting matches CP blade reporting,
rather than status reported by port blades. Table 6 (page 27) shows the changes.

Port Fencing
• When the Port Fencing trigger threshold is exceeded for ITW, LR, or CRC errors, the first set
of errors detected on an active link that meet the custom high threshold level set by the user
(or the default threshold level of approximately 6 seconds) is always ignored to account for
expected link transition errors. The port is disabled only upon detection of a second set of
errors; that is, the next time the user-set threshold level (or default threshold level) is reached.
This prevents a port from being disabled due to normal link transition behaviors.
• When using the Port Fencing feature, you must first run the fwalarmsfilterset command.
This command enables the port and allows you to receive Port Fencing messages.
• Port Fencing can be inadvertently disabled from Web Tools. This occurs when you first open
the Fabric Watch configuration window and then select the SNMP Trap check box in the
Above row. Making this change in Web Tools disables Port Fencing. If this happens, you must
re-enable the Port Fencing bit from the CLI. The Port Fencing feature is not supported for Loss
of Sync (LOS) and Link Failure (LF) areas of Port/F-port/E-port classes.
