Ethernet Packet Statistics Menu
(See Figure 3-44 on Page 80 for detailed information)
This screen provides detailed information on data exchanges between
the radio you are viewing and the network through the network layer.
These include:
Cannot pass IP
data to the WAN. a. Verify the AP IP settings.
b. Use the PING command to test communication with the AP
and endpoints connected to Remote radios in the local
radio system.
c. If successful with the local PING, attempt to PING an IP
radio attached to a radio.
d. If successful with the LAN PINGs, try connecting to a
known radio in the WAN.
Wireless retry
count is too high There may be Radio Frequency Interference (RFI).
a. If omnidirectional antennas are used, consider changing to
directional antennas. This often limits interference to and
from other stations.
b. Try skipping some zones where persistent interference is
suspected, or packets per zone are disparate.
c. The installation of a filter in the antenna feedline may be
necessary. Consult GE MDS for further assistance.
Password
forgotten. a. Connect to the transceiver using a terminal through the
COM1 port.
b. Call GE MDS. Get a password-resetting Authorization Key.
c. Enter the Authorization Key at the login prompt as a
password.
