(Data Line
Monitor Menu)
The DLM menu screen provides the ability to monitor the traffic flow at any port
of any TXPORT unit in the network. It is a very powerful troubleshooting tool,
especially at the terminal and host protocol level. It quickly identifies terminals
that do not answer their poll or retransmissions at the X.25 or frame relay level.
X.25 traffic is decoded at the frame and packet level, like a data analyzer would do
it. Frame relay LMIs are decoded as well as TXPORT’s packet-level protocol. An
example of the DLM screen is shown in Figure 4-7.
Configuration Number
This field is used to identify, by number, the configuration desired to start a
monitor on.
Configuration Name
If it is desired to start a monitor, but the number is not known, a name may be
entered. The program then initiates a search of the description field of each
configuration looking for a match. The program stops at the first match found.
Line Module
The line module number where the target port resides should be entered here.
Log To
To capture the monitored data to disk, enter a valid DOS file name here. If the file
already exists, the monitored data is appended to it.
Port
The number of the target port should be entered here.
