Interface Classification is one of the pillars behind an optimally efficient use of Kentik for Network Observability: it helps our underlying query engine understand what enters, leaves, goes through your network. Via Connectivity Type classifications, it brings business color into your flow data. While programmatic interface classification based on SNMP data is achieved by our Interface Classification engine, we realize that not all of your interfaces always come with consistent descriptions. To solve this problem we're introducing this January a whole lot of additional Interface Management capabilities to help you take classification to 100%.

Interface IP Address Overrides

We are now supporting the capability of overriding an interface’s IP address. This override works in the same way the other interface overrides work. Here are some example scenarios:

• The ability to set IP addresses for platforms that do not support obtaining the IP addresses of interfaces from SNMP
• The ability to remove the IP address that is obtained from SNMP
• The ability to set the IP address regardless of what SNMP provides

Static Interface Classification

Users are now able to statically classify interfaces from multiple areas in the product. This feature provides a good way for companies with loosely-enforced interface naming conventions to be able to correctly classify their traffic. This feature allows users to benefit from the full breadth of Network Explorer and all modules relying on Interface Classification.

Important: Interface Classification attributes (Network Boundary, Connectivity Type, Provider) defined statically per-interface will always supersede dynamic rules defined in the Interface Classification engine. As a result, the dynamic interface classification UI will also show when such static definitions are set.

The rules evaluation UI has also changed so that statically classified interfaces appear as such when they escape dynamic rules, as they always supersede them. An orange checkmark will indicate that an interface is statically classified, as displayed in the screenshot below:

From the Settings > Manage Interfaces Screen

Multiple interfaces can be selected and bulk-configured from the top-right Classify dropdown, and users can also access a more complete Interface Attributes config screen from the edit icon button at the end of each interface’s row.

The interface screen’s right-side filter section will assist the user in identifying unclassified interfaces, statically classified interfaces making the manual classification process easier.

Additionally, this panel will also assist users in identifying interfaces that have been statically classified, offering the selectors displayed in this screenshot, prefixed with the “Overridden” mention.

Lastly, users will also be able to reset an interface’s static configuration from the single interface configuration screen, as depicted below, by hitting the “Restore” link:

From Any Network Explorer > Interface Detail Screen
