• The first line shows the access point (AP) to which the device
being interrogated is currently connected AP.
• The second and third lines show other available APs and the
status of those APs.
• The information in the time 1 cell shows that a time of 1ms was
taken to create the new MPLS tunnel.
• The information in the acq 0 cell shows a connection acquisition
time of 0ms. In other words, the vehicle radio took 0ms to connect
to the wireless infrastructure radio from outside the coverage zone.
• The information in the handoff cell shows a timestamp at which the
handoff occurred of 1486754405.001680979.
• The information in the updated cell shows the timestamp at which
the last control packet was received from the connected AP.

The tables above show the physical status of the wireless TX
(transmission) connection and RX (reception) connection:
• rate shows the data transfer rate in Mbps.
• SNR shows the signal-to-noise ratio.
• RSSI shows the received signal strength in decibel-milliwatts.
• LER shows the link error rate.
• PER shows the packet error rate.
Ethernet 1 role:
ingress/egress
Ethernet 2 role:
Down
The table above shows the role of the radio unit’s Ethernet ports:
• If a Down result is shown, the port is not connected.
• If a mesh result is shown, the port allows only MPLS packets.
• If an ingress/egress mesh result is shown, the port allows all types
of data packets.
