Each feature has show commands that provide information about the feature configuration, status, and
performance. Additionally, you can use the following command for more information:
• show system—Provides information about system-level components, including cores, errors, and
exceptions. Use the show system error-id command to find details on error codes.

Consistency Checker Commands
Cisco NX-OS provides consistency checker commands to validate the software state with the hardware state.
The result of the consistency checker is logged as either PASSED or FAILED.

Consistency Check: PASSED
Cisco NX-OS supports the following consistency checker commands:
• show consistency-checker l2 module module-number—Verifies that learned MAC addresses are
consistent between the software and the hardware. It also shows extra entries that are present in the
hardware but not in the software and missing entries in the hardware.
• show consistency-checker l2 module module-number—Checks for Layer 3 settings of an interface in
the hardware and for the following configuration in the hardware: L3 VLAN, CML Flags, IPv4 Enable,
VPN ID. This command works for physical interfaces and interfaces that are part of a port channel. It
does not validate subinterfaces.
• show consistency-checker link-state module module-number—Verifies the software link state of all
the interfaces in the module against its hardware link state.
•
show consistency-checker membership port-channels [interface port-channel
channel-number]—Checks for port-channel membership in the hardware in all modules and validates
it with the software state.
• show consistency-checker membership vlan vlan-id—Determines that the VLAN membership in the
software is the same as programmed in the hardware. It also ignores the interfaces that are in the STP
BLK state.
•
show consistency-checker racl [module module-number | port-channels [interface port-channel
channel-number]]—Validates the IPv4 RACL programming consistency between the hardware and
software and verifies if <label, entry-location> pairs are consistent between the hardware and software.
When invoked per module, this command verifies IPv4 ACL consistency for all the physical interfaces
in that module.
When invoked on a specific port channel, this command verifies for all the member ports.
When invoked on all port channels, this command verifies for each port channel that has an ACL applied.
