VIFG Usage Considerations
Considerations that apply to both VIFG modes:
◼ A maximum of 2,000 VIFGs can be configured or discovered automatically.
◼ The ID of the VIFG will not change if its members change.
◼ One capture job can be associated with multiple VIFGs.
◼ Capture jobs provide the option to include all configured groups.
◼ If a subset of the VIFGs associated with a capture job are removed, the capture job will continue capturing traffic from the remaining VIFGs.
◼ A capture job is not removed if all of its associated VIFGs are removed. The capture job can be modified to include different VIFGs.
◼ Every VIFG (in either mode of operation) will return these new settings:
◼ MTU: This will be the maximum of the MTUs of the interfaces the VIFG collects (in monitoring interface mode) or the maximum of all interfaces' MTUs (in VLAN mode).
◼ Bandwidth Capacity: This will be the sum of the link speeds of the interfaces ithe VIFG collects (in monitoring interface mode) or the maximum of all interfaces' link speeds (in VLAN mode).
◼ While the MTU is a read-only value, the Bandwith Capacity can be configured through REST (and in the Web UI).
