It is found that under 13 hours of stressed traffic test with PAUSE flow control on 10G, less than 100
PAUSE frames were seen with CRC error, none on data frame. Broadcom has been notified but they have
not been able to provide any answer. However, this should not be an issue as the default PAUSE setting is
OFF and the rate of corruption is extremely low (<100 out of 23 millions PAUSE frames).
Workaround: Do not turn on PAUSE flow control in 10G.
PR 79958
It is found that after a CLI command issuing an ADMIN DOWN to a 10G link, a few corrupted packets
are seen on the remote station. This is believed to be a side effect of Xenpak which chop off the packet
abruptly when the Rx and Tx link is disabled. However, this happens only under very heavy traffic.
Workaround: There is no known workaround at this time.

PR 83062
The 10G interface may not come up upon initial boot up while traffic is running. It may be due to insuffi-
cient internal IPC resource.
Workaround: Plug the fiber in after the switch boot up or NI hot swap.
