Parameter Description
The Master setting will allow the port to advertise capabilities related to duplex,
speed, and physical layer type. The master setting will also determine the master
and slave relationship between the two connected physical layers. This
relationship is necessary for establishing the timing control between the two
physical layers. The timing control is set on a master physical layer by a local
source.
The Slave setting uses loop timing, where the timing comes from a data stream
received from the master. If one connection is set for master, the other side of the
connection must be set for slave. Any other configuration will result in a 'link down'
status for both ports.
Options to choose from are:
• Auto - Specifies that for copper ports, auto-negotiation will start to negotiate
the speed and flow control with its link partner. For fiber ports, auto-
negotiation will start to negotiate the clock and flow control with its link
partner.
• 10M - Specifies to force the port speed to 10 Mbps. This option is only
available for 10 Mbps copper connections.
• 100M - Specifies to force the port speed to 100 Mbps. This option is only
available for 100 Mbps copper connections.
• 1000M - Specifies to force the port speed to 1 Gbps.
• 1000M Master - Specifies to force the port speed to 1 Gbps and operates
as the master, to facilitate the timing of transmit and receive operations.
• 1000M Slave - Specifies to force the port speed to 1 Gbps and operates as
the slave, to facilitate the timing of transmit and receive operations.
• 2500M - Specifies to force the port speed to 2.5 Gbps.
• 2500M Master - Specifies to force the port speed to 2.5 Gbps and operates
as the master, to facilitate the timing of transmit and receive operations.
• 2500M Slave - Specifies to force the port speed to 2.5 Gbps and operates
as the slave, to facilitate the timing of transmit and receive operations.
• 10G - Specifies to force the port speed to 10 Gbps.
• 10G Master - Specifies to force the port speed to 10 Gbps and operates as
the master, to facilitate the timing of transmit and receive operations.
• 10G Slave - Specifies to force the port speed to 10 Gbps and operates as
the slave, to facilitate the timing of transmit and receive operations.
Capability Advertised When the Speed is set to Auto, these capabilities are advertised during auto-
negotiation.
