One of Kentik Detect’s most powerful features is the ability to add additional context to netflow data using flow tags or custom dimensions (see our Flow Tags and Custom Dimensions KB articles). We’ve now extended this feature by enabling tags and custom dimension populators to match on the VLAN ID of flow records. The value for VLAN ID accepts comma-separated values between 0 and 4095 (inclusive), as well as integer ranges, all of which can be intermingled in the same list.
