The IGX Feeder Node
The IGX can be a feeder node to a BPX, another IGX, or certain MGX platforms. Because of the
interdependence among the devices and the large-scale network management required in a tiered
network, Cisco recommends that you use Cisco WAN Manager (CWM) to configure and manage the
devices in the tiered network. This section describes how to enable and disable the feeder node
functionality on the IGX.
Note Refer to the release notes for each platform and software release that you plan to use in your tiered
network for complete information on feeder functionality support, restrictions, requirements, and
platform interdependencies.
