Parameters

**Table 1** Descriptions of the parameters for Ethernet interface Advanced Attributes
Field	Value	Description
Port	For example: Slot-Board Name-Port (Port No.)	Displays the port name.
Port Physical Parameters	For example: Port Enable: Enabled, Working Mode: Auto-Negotiation, Non-Autonegotiation Flow Control Mode: Disabled, MAC Loopback: Non-Loopback, PHY Loopback: Non-Loopback	Displays physical parameters of the port. NOTE: When you query the Port Physical Parameters of a port, negotiating may be displayed. It indicates that the port has self-negotiation capability but the negotiation is not completed.
MAC Loopback	Non-Loopback, Inloop, Outloop	Sets the loopback state of the MAC layer.
PHY Loopback	Non-Loopback, Inloop, Outloop	Sets the loopback state of the PHY layer.
MAC Address	For example: 00-5A-3D-03-4C-1B	Displays the MAC address of the port.
Transmission Rate (kbit/s)	For example: 1024	Displays the rate at which the data packets are transmitted.
Receiving Rate (kbit/s)	For example: 1024	Displays the rate at which the data packets are received.
Loopback Check	Enabled, Disabled	Sets the loop detection. When this function is enabled, the equipment automatically checks whether a loop is generated on the link. If a loop is generated, the relevant alarm is reported.
Loopback Port Shutdown	Enabled, Disabled	Sets the automatic block of the port. When Loopback Check is set to Enabled and Loopback Port Shutdown is set to Enabled, the equipment automatically checks whether a loop is generated on the link. If a loop is generated, the port is automatically block to release the loop.
Egress PIR Bandwidth (kbit/s)	1000 to 100000	Sets the egress PIR bandwidth.
Enable Receive/Transmit of Extended 3ah Packet	Enabled, Disabled	Enables or disables the functions of receiving and transmitting 3ah extended packets through this port. If the functions are enabled, the port can process certain information that 3ah extended packets carry. To be specific, the port can process the information about whether the current link is the working or protection link in the protection group. Otherwise, the port cannot process such information.
Receive/Transmit Mode of Extended 3ah Packet	Receive, Transmit, All	Specifies the mode of receiving or transmitting 3ah extended packets. Receive: The port can only receive 3ah extended packets. Transmit: The port can only transmit 3ah extended packets. All: The port can transmit and receive 3ah extended packets. NOTE: Currently, this parameter can be set to only Receive.
Broadcast Packet Suppression	Disabled, Enabled Default: Disabled	By using this parameter, you can enable or disable the broadcast packet suppression function for a port. This controls the volume of the incoming broadcast packets on a port. When the broadcast packet suppression function is enabled for a port and the volume of the incoming broadcast packets exceeds the preset threshold on the port, all incoming broadcast packets are discarded.
Broadcast Packet Suppression Threshold (%)	For example: 30	When the broadcast packet suppression function is enabled, if the broadcast packet occupies a bandwidth that exceeds the overall bandwidth of the port x the suppression threshold, the broadcast packet is suppressed.
Broadcast Packet Suppression Threshold (Mbit/s)	0 to 10000	When the broadcast packet suppression function is enabled, if the broadcast packet occupies a bandwidth that exceeds the overall bandwidth of the port x the suppression threshold, the broadcast packet is suppressed. NOTE: Only OptiX OSN 3500/3580, OptiX OSN 7500 and OptiX OSN 7500II support the parameter.
Inter-Packet Gap(bytes)	8 to 12	Invalid characters are used to fill the gap between the frames, namely, the inter-packet gap, which indicates the interval between sending the packets. The inter-packet gap can be changed to improve the ports' capabilities to forward data packets. An inter-packet gap can be specified for a GE optical interface, a GE electrical interface, or an FE optical interface. The value of inter-packet gap on relative interface must be the same. Inconsistent inter-packet gap settings may result in packet loss.
Network Cable Mode	MDIX, Auto-Sensing, MDI	Selects the mode of network cable.
Optical Module Type	Unknown, Single-Fiber Bidirectional, Two-Fiber Bidirectional	Indicates the optical module type if an optical module is inserted into the port. Unknown: Indicates that no optical module is inserted into this port. Single-Fiber Bidirectional: Indicates that a single-fiber bidirectional optical module is inserted into this port. Two-Fiber Bidirectional: Indicates that a two-fiber bidirectional optical module is inserted into this port.
Unidirectional Operation	Enabled, Disabled	Specifies whether to enable the unidirectional operation mode for a 10GE port. Enabled: Indicates that the port works in unidirectional mode. When faults occur only in the transmit or receive direction, only the transmit or receive functions are disabled for the port. For example, a LOS fault occurs in the receive direction. In this case, only the receive functions are disabled for the port while the transmit functions are still working. Disabled: Indicates that the port does not work in unidirectional mode. A unidirectional fault will cause both the transmit and receive functions to be disabled for the port. For example, a LOS fault occurs in the receive direction. Then both the receive and transmit functions are disabled automatically.
Synchronous Clock Enabled	Enabled, Disabled	Enables or disables the synchronous clock.
PoE	Enabled, Disabled, Auto-Negotiation	local NE provides the power for the remote NE by Ethernet interface. Auto-Negotiation indicates that the local NE learns power on the remote NE by negotiation and supplies moderate power to the remote NE. NOTICE: Modifying the status of PoE may interrupt the services. Exercise caution for this.
PoE Status	Disabled, Enabled	Indicates the actual PoE status.
Mapping Protocol	GFP-F, GFP-T Default: GFP-F	Indicates the Generic Framing Procedure (GFP) used by Ethernet services that traverse virtual ports on universal line boards.
Enable Bit Error Detection	Disabled, Enabled Default: Disabled	When Enable Bit Error Detection is set to Enabled, the bit error detection function based on Ethernet ports is enabled. In this case, EXC Threshold for Packet Loss at Port and SD Threshold for Packet Loss at Port can be set.
EXC Threshold for Packet Loss at Port	1.0E-2, 1.0E-3, 1.0E-4, 1.0E-5	The value of EXC Threshold for Packet Loss at Port must be equal to or larger than that of SD Threshold for Packet Loss at Port. NOTE: The same BER may affect different base stations to different extents, so you need to set bit error thresholds as required.
SD Threshold fort Packet Loss at Port	1.0E-5, 1.0E-6, 1.0E-7, 1.0E-8, 1.0E-9	The value of EXC Threshold for Packet Loss at Port must be equal to or larger than that of SD Threshold for Packet Loss at Port. NOTE: The same BER may affect different base stations to different extents, so you need to set bit error thresholds as required.
Enable Switching Bit Triggered by Bit Error	Disabled, Enabled Default: Disabled	When Enable Switching Triggered by Bit Error is set to Enabled, tunnel APS protection switching is triggered when the BER crosses the threshold. The specific threshold is the one corresponding to Switching Mode Triggered by Bit Error.
Switching Mode Triggered by Bit Error	SD, SF	Specifies the type of switching that is triggered by bit errors. SD: When the detected BER is larger than the value of SD Threshold for Packet Loss at Port, an alarm will be reported and protection switching will be triggered. SF: When the detected BER is larger than the value of SD Threshold for Packet Loss at Port, an alarm will be reported; when the BER is larger than the value of EXC Threshold for Packet Loss at Port, an alarm will be reported and protection switching will be triggered.
Mapping Protocol	GFP-F, GFP-T Default: GFP-F	Indicates the Generic Framing Procedure (GFP) used by Ethernet services that traverse virtual ports on universal line boards.
Hold-off Time(s)	0 to 86400	Indicates the hold-off time. For various reasons, microwave links may trigger Layer 3 protocol and signaling re-calculation and it takes much time to recover services. To ensure that microwave links run stably, users need to set the hold-off time.
