This page allows administrators to set the alarm, and duplex settings of the Ethernet connection.

• For models with multiple Ethernet ports, NMS Management allows determination of the
management information using the following management modes:
– In-band: Management traffic is carried over the air and is available from all connectors on
either end of the link.
– Out-of-band: Management traffic is not carried over the air and is only available from the
port(s) configured for Management.
– Port-to-Port: Management traffic remains separate from data traffic without requiring out-of-
band management or VLAN configuration. This allows any Ethernet port on the link to be
logically mapped to the same port at the other end of the link without requiring VLANs to be
configured. The traffic passing through these mapped ports is not accessible from any of the
other available Ethernet ports on either side of the link.
• Set the Ethernet ports on the radio and connected equipment to 100/full-duplex for best
performance. If the Ethernet ports are set to auto-negotiation, poor throughput performance may
be a result, as well as intermittent disconnections of the Ethernet connection.
• The Flow Control setting allows the enabling of 802.3 Ethernet flow control, useful for systems
implementing QoS or other traffic flow control implementations.
• The Alarm function can be enabled or disabled for each port. Generally, all constantly connected
port alarms should be enabled, and unused or maintenance-only ports should have alarms disabled.
• For models with multiple Ethernet ports, the Mute setting allows signalling to connected network
devices when the radio link is down such as for spanning tree protocol.
