• The DMG1000 log can store up to 1.5 Mbytes, while the DMG2000 log can store up to 32
Mbytes.
•
Trace Capture is automatically enabled at power-on-with Error, Debug and Init trace masks for
all trace keys.
9.4.3 Network Capture
The Network Capture creates an in-memory log of Media Gateway IP traffic. Since there can be a
great deal of traffic, the Network Capture control page allows filtering of IP packets. Filtering
packets makes it easier to analyze problems by reducing the number of irrelevant messages. It also
increases the time before the log wraps, thus making it more probable an error will be caught.
9.4.3.1 Network Capture Details
The DMG1000 unit has one network interface:
• LAN1: an external network that connects the DMG1000 to a VOIP network
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 63. 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 63. Network Capture Control Page - DMG2000
Figure 63 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
