Defect ID: DEFECT000369703
Technical Severity: High
Summary: Host could not Link up on 8G FC port when the port is configured at a fixed speed of 4G or
8G.
Symptom: After switch reboot, or slotpoweroff/slotpoweron, a port may sometimes not gain sync and
also fail to recover using portdisable/portenable. This may occur when an 8G port is
configured at fixed speed of 4G or 8G, and the remote end is configured to auto negotiate,
and it is the only port connected to the remote end. This problem is not observed when
more than 1 port is connected to the remote end.

Defect ID: DEFECT000374065
Technical Severity: High
Summary: During hafailover, if there are too many timed-out and un-routable frames being forwarded
to the CPU, there is potential for a port to lose credits.
Symptom: Switch encountered many timeouts and destination unreachable frames due to a rare
configuration error. A HA fail-over while in this state resulted in hosts losing access to
targets.
