Limitations
This section describes the limitations for Cisco NX-OS Release 5.0(3)N2(1) and Release 5.0(3)N2(2).
• When upgrading from Cisco NX-OS Release 4.2(1)N1(1) and earlier releases, to any release, the
policy description is lost. This problem does not occur when upgrading from Cisco NX-OS
Release 4.2(1)N1(1) and later releases. After an upgrade, We recommend that you reconfigure the
policy description. For details, see CSCth14225.
• Starting with Cisco NX-OS Release 4.2(1)N2(1), LACP fast timers are supported. If you downgrade
to an earlier release that does not support this feature, entering the install all command displays the
following warning:
"Configuration not supported - Lacp fast rate is enabled",
"Use \"lacp rate normal\" on those interfaces"
