Abstract
Segregating a node port experiencing ingress. A node that provides a service to a plurality of cable modems may have a plurality of node ports. The node may be a Remote PHY Node or a Remote MACPHY node. In response to detecting that a particular node port of the node is experiencing ingress, the assignment of node ports to upstream device ports are adjusted so that the particular node port experiencing ingress is not be assigned to the same upstream device port as any other node port. In further response to detecting ingress at the particular node port, all node ports assigned to the same upstream device port are caused to be assigned to the same downstream device port. By segregating the node port experiencing the ingress in this manner, the impact of that ingress can be mitigated or eliminated with respect to the other node ports of that node.
