Abstract:
1. A configuration method in a network element, comprising: receiving, on a first port of said network element, first configuration information from a first peer device coupled to said first port, said first port having an assigned port role of auto-configuration upstream, wherein said assigned port role of auto-configuration upstream enables said network element to advertise a configuration to said first peer device and to accept a configuration advertised by said first peer device; configuring said network element based on said received first configuration information; and transmitting, on a second port of said network element, second configuration information to a second peer device coupled to said second port, said second configuration information being based on said first configuration information, said second port having an assigned port role of auto-configuration downstream, wherein said assigned port role of auto-configuration downstream enables said network element to advertise a configuration to said second peer device and to prevent a configuration advertised by said second peer device from being accepted by said network element.
