Configuring CX Devices

The CX devices that are monitored by CXMon require some basic configuration. You can use Memotec’s CXTool application to perform this configuration.

The table below summarizes the minimum CXTool version required for each type of application.

NOTE: CXMon is not supported on all the devices supported by CXTool. See the

“System Limitations” on page 1-5 for the list of device types supported by CXMon.

For more information about using CXTool, refer to the CXTool User Guide and CXTool Online Help. You must have at least one new or existing configuration file to configure your CX device.

To configure your CX devices with CXTool, follow these steps:

1. Launch CXTool and open the profile for your CX device.

2. Using the panel on the left, open System folder, double-click one of the icons, and select Modify from the pop-up menu. The System Information dialog box appears.

Application Minimum CXTool required for CXMon support

Abis/Ater on CX CXTool 4.3.5B

DCME on CX CXTool 4.6.09

Abis/Ater with EDGEPlus on CX CXTool 5.0.0u

Abis/Ater with EDGEPlus and DCME on CX-U CXTool 5.1.04 EDGEPlus/DCME on ‘C’ flavor (CX/CX-U) CXTool 5.2.0k

ATM/TDM/IMA (CX-U) CXTool 6.1.09k

Abis/Ater with AbisXpress (CX-U) CXTool 6.1.09k Table 3-1: CXTool version supporting CXMon

3. Select the SNMP tab and check that the CXMon Enabled is checked.

4. In order to collect SNMP Traps, you must create a Trap Host entry with the IP address of the PC that has CXMon installed. This parameter defines the destination IP address for all SNMP trap packets from this CX. You can configure multiple destinations if you are using multiple SNMP Monitoring systems.

5. Configure the SNMP Source Address with the required IP address. This parameter defines the source IP address for all SNMP packets originating from this CX device.

Normally the IP address with the shortest path to the monitoring PC is configured. To set the source IP address, select the right IP interface (usually the one on the same network as the monitoring PC) from the list.

NOTE: The next step only applies to the CX2000 device, so if you do not have this device, skip to the next step.

Define the source IP address for all SNMP packets.

6. The ^CX2000 requires that a unique IP address be assigned to each CPU. If you cannot have an Ethernet card in each CPU, you can configure virtual IP addresses. This is accomplished by configuring a Vista Address for each CPU.

The Vista Address will define the source address for all SNMP packets originating from this CX. This serves the same function as the Agent Interface Alias. All SNMP requests should match one of the configured Vista Address entries.

7. CXTool will automatically define the WAN Index for all DIM ports when

configuration is made using either the FR WAN Trunk, IP WAN Trunk, or MLPPP WAN Trunk panels.

But if the WAN is configured without using one of these panels then the WAN Index must be added manually (in the panel on the left, double-click the ^Advanced folder and double-click the Add-On Scripts message on the right panel) using the following command for each DIM interface:

vpstats:15 wanidx=11, vrsridx=1

In this example the DIM interface is located in slot 8, port 1 (15) and the WAN interface is located in slot 1, port 1 (11). The VRSR used by the DIM traffic is VRSR:1.

The vpstats and wanidx values identify the slot and port of the corresponding WAN interface used by the DIM port for transport to the remote location.

NOTE: The WAN interface must be on the same CPU as the DIM Port.

The wanidx values identify the slot and port of the corresponding WAN interface used by the DIM port for transport to the remote location.

3.1.3 Vpstats vrsr index values

The vrsridx value identifies the VRSR entry used by this port, when over the WAN interface. It has the same value as the VRSR index value in the CX/CX-U configuration.
