Method used to set the Ethernet working mode of a GE port on the TOA board
Ethernet Working Mode can be set to Auto-Negotiation or 1000M Full-Duplex. The default value is 1000M Full-Duplex. Auto-Negotiation can automatically determine the optimal working modes of the interconnected ports. This mode facilitates maintenance. Ethernet Working Mode is valid only when the service type is set to GE (TTT-GMP). The Ethernet working mode must be consistent with the setting for upstream services. Two ports that are mutually protected in active-standby mode must have the same Ethernet Working Mode setting.
