Viewing Consistency Check

This chapter contains the following sections:

Consistency Check

Consistency check shows the number of controller or node inconsistencies for each device and provides option to resolve the inconsistency issues. The consistency check feature shows two types of inconsistencies:

  • Controller flows inconsistency: Flows are present in Cisco NDB, but missing from the device.

  • Node flows inconsistency: Flows are present in the switch, but missing from Cisco NDB.


Note

Starting with Cisco NDB Release 3.6, consistency check option is now available for NX-API based devices along with the OpenFlow based devices.
