When upgrading from pre Cisco NX-OS 4.2(1)N1(1) releases, to any release, policy description is
lost. This problem does not exist when ugprading from Cisco NX-OS Release 4.2(1)N1(1) and
beyond and any future releases. You should re-configure policy description after an upgrade. For
details see, CSCth14225.

Staring with the with Cisco NX-OS Release 4.2(1)N2(1) release, LACP rate fast is supported. If you
would like to downgrade to previous releases, install all prints the following warning:
would like to downgrade to previous releases, install all prints the following warning:
"Configuration not supported - Lacp fast rate is enabled",
"Use \"lacp rate normal\" on those interfaces"
You should change the Lacp rate to normal before downgrading. If you ignore the warning and force
install all to proceed, then it is possible that the leftover LACP rate fast configuration would still be
active with previous releases of software but the behavior would be unpredictable and link flap may
occur. It is recommended that you follow the warning from install all and change the lacp rate
setting to normal. For details see, CSCth93787

When an FC SPAN dest port is changed from SD to F mode and back to SD mode on a NPV switch,
the port goes into error-disabled state. Perform a shut/no-shut after the mode change recovers the
port. This problem is only with NPV mode. For details, see CSCtf87701

If you configure a Nexus 2248TP port to 100Mbps speed instead of auto-negotiation ,
auto-negotiation does not occur. This is expected behavior. Both sides of the link should be
configured to both hardwired speed or both autonegotiate.

no speed autonegotiates, advertises all speeds (only full duplex)
speed 1000 autonegotiates only for a 802.3x pause
speed 100 does NOT autonegotiate, pause cannot be advertised. Peer must be set to NOT

Given the implementation of single CPU ISSU, stp root on pvst region with the switches on mst
region is not supported. The pvst simulation on the boundary ports go into pvst sim inconsistent
blocked state. So the stp active path is broken. In order to avoid this, to avoid the above, move all
stp root on mst region. By doing so you cannot support non-disruptive ISSU since it will fail for No
Non-Edge Designated Forwarding Ports required for ISSU . For details see CSCtf51577. Refer to
the configuration guide for scenarios and topology in which non disruptive upgrade is supported.
