Diagnostics
The DMG2000 unit has three network interfaces:
• DSP: an internal network that connects the DMG2000 DSP to the DMG2000 CPU
• LAN1: an external network that connects the DMG2000 to a network (VOIP)
• LAN2: an external network that connects the DMG2000 to a network (non-VOIP)
Notes: 1. The DMG1000's LAN1 is equivalent to the DMG2000's LAN1.
2. Currently, LAN2 is only supported in Version 5.1 SU1 Software or later.
The Network Capture is controlled from the Media Gateway's Web interface. The DMG2000
Network Capture control page is shown in Figure 59. Even though the DMG1000 control page has
only one network interface (LAN1), the ideas presented in this section apply equally to the
DMG2000 and the DMG1000.
Figure 59. Network Capture Control Page - DMG2000
Figure 59 shows the default values (i.e. immediately after power-up) for a DMG2000. The first
level of filtering occurs on the interface level. You can select Capture to enable or Do not capture
to disable individual interfaces. The second level of filtering is on the protocol level. When an
interface is enabled (Capture), you have the ability to filter (not log) different protocols. A check
mark in the box means the Gateway will not log packets of the corresponding protocol.
To use the Network Capture, first select the interfaces to capture, check the protocols you do not
want to log, click Apply Filters and then click Start Capturing. Logging starts and the display
changes to show the state of the log. An example of a running log is shown in Figure 60.
