Methods and systems are provided for managing an Ethernet ring protection switching (ERPS) protocol in an Ethernet network. The method includes receiving an administrative data packet at a first network element; determining whether the administrative data packet contains an ERPS membership setting from a second network element; when the administrative data packet contains the ERPS membership setting from the second network element, comparing an ERPS membership setting at the first network element to the ERPS membership setting from the second network element; and performing an action when the ERPS membership setting at the first network element is different than the ERPS membership setting from the second network element.

Auto detection and prevention of loop, segmentation and traffic outage in a G.8032 ring network

Methods and systems are provided for migrating loop-breaking protocols in an Ethernet network. The method includes selecting a virtual local area network (VLAN) implementing a multiple spanning tree protocol (MSTP) from a plurality of VLANs operating on the Ethernet network, the MSTP having a spanning tree with a root network element coupled to a first branch of network elements; disabling a virtual network link in the VLAN; migrating a first leaf network element of the first branch in the VLAN by disabling the MSTP and enabling an Ethernet ring protection switching (ERPS) protocol on the first leaf network element; migrating the root network element in the VLAN after the first leaf network element by disabling the MSTP and enabling the ERPS protocol on the root network element; and enabling the virtual network link after migrating the first leaf network element and the root network element.

Seamless migration from multiple spanning tree protocol to ethernet ring protection switching protocol

Methods and systems are provided for migrating loop-breaking protocols in an Ethernet network. The method includes disabling a port of a first leaf network element in a network implementing a rapid spanning tree protocol (RSTP), the RSTP having a spanning tree with a root network element coupled to the first leaf network element forming a first branch of the spanning tree; migrating the first leaf network element by disabling the RSTP and enabling an Ethernet ring protection switching (ERPS) protocol on the first leaf network element; migrating the root network element after the first leaf network element by disabling the RSTP and enabling the ERPS protocol on the root network element; and enabling the port of the first leaf network element after migrating the first leaf network element and the root network element.
