Configuring a Graceful Consistency Check

Beginning with Cisco NX-OS Release 5.2(1), you can configure the graceful consistency check feature,
which is enabled by default. Unless this feature is enabled, the vPC is completely suspended when a
mismatch in a mandatory compatibility parameter is introduced in a working vPC. When this feature is
enabled, only the links on the secondary peer device are suspended. See the
for vPC Interfaces" section on page 7-15
