A virtual interface group (VIFG) is a logical collection of one or more monitoring interfaces or VLANs that AppResponse 11 treats as a single interface and uses as a source for traffic analysis or packet capture. Prior to Version 11.5.0, these groups were known as monitoring interface groups (MIfGs), and included monitoring interfaces only, not VLANs. VIFGs, like MIfGs in earlier versions, can be configured with additional properties such as packet deduplication and traffic filters (BPF or SteelFilter). Refer to SteelFilter Identifiers Supported For NPM Capture for the set of SteelFilter identifiers that are supported for use with VIFGs.

VIFGs are configured and managed using the Virtual Interface Groups tab on the Capture Jobs/Interfaces page.
