Consistency checking in logical interconnect configurations

Consistency checking validates a logical interconnect to ensure that it matches the configuration of its parent logical interconnect group. HPE OneView appliance monitors both the logical interconnect and the logical interconnect group, compares the two, and checks the following for consistency:

Resources

Consistency checking

Interconnect settings

Are there differences in the following logical interconnect settings from the expected configuration defined by the logical interconnect group?

  • Enabling Fast MAC cache failover

  • MAC refresh intervals

    Interconnect settings
  • Storm control

  • Loop protection

  • Pause flood protection

IGMP settings

Are there differences in the following IGMP settings from the expected configuration defined by the logical interconnect group?

  • IGMP snooping

  • IGMP idle timeout interval

  • IGMP multicast flood protection

  • IGMP proxy reporting

Uplink sets

Are there differences in port assignments or network associations from the configuration defined by the logical interconnect group? Did you add an uplink set?

Internal networks

Are there differences in the network assignments for server-to-server communication from the configuration defined by the logical interconnect group?

Interconnect maps

Has the logical interconnect group been edited?

Quality of Service (QoS) settings

Have the network service requirements been edited?

If both configurations match, the logical interconnect Consistency state field is set to Consistent and is considered to be compliant.

Any inconsistency results in an alert for the logical interconnect and the Consistency state field is set to Inconsistent with group and the interconnect configuration must be updated.

The Logical Interconnects Group screen provides an option to exclude sections from consistency checking.

You can resolve consistency conflicts either manually or automatically. The Update from group option automatically remediates consistency conflicts. You must manually resolve inconsistencies when there are issues with the existing logical interconnect configuration or when the Update from group option is unable to update the logical interconnect configuration.

Consistency checking provides these options:

  • Exact match: Verifies the logical interconnect and the logical interconnect group match exactly.

    Sections in the logical interconnect group that are excluded during consistency checking are applied with the Exact match option during automatic conflict remediation.

  • Minimum match: Verifies basic logical interconnect configurations match logical interconnect group settings. Extra configurations in the logical interconnect, if any, are retained during automatic remediation. Conflicting configurations, if any, are not auto remediated during automatic remediation.

    This check is the default consistency check for uplink sets and internal networks.

  • Not checked: Enables configuration settings in the logical interconnect to deviate from the settings in the logical interconnect group. HPE OneView does not flag discrepancies in the consistency report.
