• Example #2
• Link Off Duration 20 seconds
• Link Off Spacing 120 seconds
The Data port’s Ethernet link will be initially
disconnected when the RF link first goes down. That
event will start a 120-second timer. The RF link goes
back up after 10 seconds; however, that does not
affect the Ethernet link. The Ethernet link will remain
offline for 20 seconds and then come back online.
The RF link goes down again after 60 seconds;
however, that does not affect the Ethernet link.
The Ethernet link will then remain online until the
120-second timer expires.
• Enabled This option is designed for use by operators
who are not using in-band management. The Track
Radio Link option is enabled without timers, so the Data
port’s Ethernet link follows the RF link state exactly. If
the RF link goes down, then the Ethernet link goes down
and remains down until the RF link goes back up.
MGMT Port Ethernet Settings
MGMT Speed This is the speed of the Management
port. By default, the option is Auto. The airFiber AF-5
automatically negotiates transmission parameters, such as
speed and duplex, with its counterpart. In this process, the
networked devices first share their capabilities and then
choose the fastest transmission mode they both support.
To manually specify the maximum transmission link
speed and duplex mode, select one of the following
options: 100 Mbps‑Full, 100 Mbps‑Half, 10 Mbps‑Full,
or 10 Mbps‑Half. If you are running extra long Ethernet
cables, a link speed of 10 Mbps could help to achieve
better stability.
Full-duplex mode allows communication in both
directions simultaneously. Half-duplex mode allows
communication in one direction at a time, alternating
between transmission and reception.
