1-4.9 Configuration, Operation, and Monitoring
The Link CX and radio link are configured, operated and monitored through one of five user interfaces.
The five interfaces are:
• A built-in web server GUI hosted by the Link CX, which can be accessed by any local or
remote computer equipped with a web browser. This is the interface most operators will use
to interact with the Link CX. The web browser can access the Link CX built-in web server
through either the ETHERNET 1 or ETHERNET 2 port.
• SNMP traps, which communicate with MIB-II compliant NMSs (Network Management
Systems) and EMSs (Element Management Systems). This interface is used by operators
who want real-time notification of radio problems. The Link CX sends SNMP traps to NMSs
and EMSs over Ethernet links through either the ETHERNET 1 or ETHERNET 2 port.
• An ASCII command line interface, accessible through the RS-232 CRAFT port, or through
the ETHERNET 1 or ETHERNET 2 port using telnet. This interface is primarily used by opera-
tors and interWAVE technical support personnel when performing detailed troubleshooting.
• The RSSI port, providing a DC voltage level proportionate to the received RF signal level, and
allowing installers to use a DC voltmeter to fine-tune antenna alignment. This interface is
primarily used during installation, but the current RSSI measurement is also available via the
Link CX built-in web server or via SNMP polls.
• Five LEDs that provide visual alarm status. They verify proper operation of the Ethernet
ports, DS-3 ports, and radio link, and indicate proper power input and radio operation.
These LEDs are usually used during installation to provide a quick product verification.
1-4.10 SNMP
The Link CX radio supports SNMP network management. SNMP is a protocol that defines the method of
communicating with and controlling network devices.
Devices that support the SNMP protocol can be queried for their status and other device information.
Some devices allow changing device settings or configurations using SNMP commands. The device
settings and other device data are available as variables. They are defined in the standard Management
Information Base (MIB) file, provided by the device manufacturer. The SNMP manager uses a database
to hold lists of variables that can be accessed for each device on the network. The device data can be
displayed in tables, graphs, or saved in a file.
1-4.11 Link CX Network Management Architecture
Link CX software network management is comprised of two main items:
• SNMP based Network Management System (NMS) application in the network management
workstation.
Note that the ETHERNET 1 and ETHERNET 2 ports are functionally
equivalent, and that they are both served by an onboard Ethernet
controller. The controller automatically switches polarity on the transmit
and receive pairs when they are reversed, eliminating the need for
crossover cables.
