Configuring Port Connections - AMX NXA-ENET8-2POE Operation/Reference Manual

Configuring Port Connections

Use the Port Configuration page to configure the connection parameters for each port. This page includes
options for enabling auto-negotiation or manually setting the speed and duplex mode, enabling flow control,
setting the maximum frame size, specifying the response to excessive collisions, or enabling power saving
mode.

Indicates if the link is up or down.
Sets the port speed and duplex mode using auto-negotiation or manual selection.
The following options are supported:
Disabled - Disables the interface. You can disable an interface due to abnormal
behavior (e.g., excessive collisions), and then re-enable it after the problem has
been resolved. You may also disable an interface for security reasons.
Auto - Enables auto-negotiation. When using auto-negotiation, the optimal
settings will be negotiated between the link partners based on their advertised
capabilities.
1Gbps FDX - Supports 1 Gbps full-duplex operation
100Mbps FDX - Supports 100 Mbps full-duplex operation
100Mbps HDX - Supports 100 Mbps half-duplex operation
10Mbps FDX - Supports 10 Mbps full-duplex operation
10Mbps HDX - Supports 10 Mbps half-duplex operation
(Default: Autonegotiation enabled; Advertised capabilities for RJ-45: 1000BASE-
T - 10half, 10full, 100half, 100full, 1000full; SFP: 1000BASE-SX/LX/LH -
1000full)
Note: The 1000BASE-T standard does not support forced mode.
Autonegotiation should always be used to establish a connection over any
1000BASE-T port or trunk. If not used, the success of the link process cannot be
guaranteed when connecting to other types of switches.
Flow control can eliminate frame loss by blocking traffic from end stations or seg-
ments connected directly to the switch when its buffers fill. When enabled, back
pressure is used for halfduplex operation and IEEE 802.3-2005 (formally IEEE
802.3x) for fullduplex operation. (Default: Disabled)
When auto-negotiation is used, this parameter indicates the flow control capability
advertised to the link partner. When the speed and duplex mode are manually set,
the Current Rx field indicates whether pause frames are obeyed by this port, and
the Current Tx field indicates if pause frames are transmitted from this port.
Avoid using flow control on a port connected to a hub unless it is actually required
to solve a problem. Otherwise back pressure jamming signals may degrade over-
all performance for the segment attached to the hub.
