Expression Description
udp.port, tcp.port Transport layer
udp.srcport, tcp.srcport Transport layer for source port
udp.dstport, tcp.dstport Transport layer for destination port
and, &&, ==, <, > Between expressions
Below are examples of configured expressions for the 'Value' parameter:
udp && ip.addr==10.8.6.55
ip.src==10.8.6.55 && udp.port>=5000 and udp.port<6000
ip.addr==10.8.6.40
For conditions requiring the "or" / "||" expression, add multiple table rows. For example, the
Wireshark condition "(ip.src == 1.1.1.1 or ip.src == 2.2.2.2) and ip.dst == 3.3.3.3" can be
configured using the following two table row entries:
1. ip.src == 1.1.1.1 and ip.dst == 3.3.3.3
2. ip.src == 2.2.2.2 and ip.dst == 3.3.3.3
Note: If the 'Value' field is left empty, the device will record all IP traffic types.
60.5 Viewing Syslog Messages
You can use the following tools to view the Syslog messages sent by the device:
Web interface's Message Log page (see below).
CLI -The device sends the error messages (e.g. Syslog messages) to the CLI console
as well as to the original configured destination. Use the following commands:
debug log ; Starts the debug
no debug log ; Stops the debug
no debug log all ; Stops all debug process
Any third-party Syslog server (e.g., Wireshark).
The procedure below describes how to view Syslog messages in the Web interface.
Notes:
• It's not recommended to keep a Message Log session open for a
prolonged period. This may cause the device to overload. For prolonged
(and detailed) debugging, use an external Syslog server.
• You can select the Syslog messages in this page, and copy and paste
them into a text editor such as Notepad. This text file (txt) can then be
sent to AudioCodes Technical Support for diagnosis and troubleshooting.
