User's Manual 57. Syslog and Debug Recordings
Version 6.8 743 Mediant 500L MSBR
Parameter Description
Capture Type
CLI: capture-type
[LoggingFilters_CaptureType]
Enables debug recordings for the defined logging filter and defines
what to record:
 [0] None (default)
 [1] Signaling = Information related to signaling such as SIP
signaling messages, Syslog, CDR, and the device's internal
processing messages.
 [2] Signaling & Media = Signaling and media (RTP/RTCP/T.38).
 [3] Signaling & Media & PCM = Signaling, media, and PCM
(voice signals from and to TDM).
 [4] PSTN trace = ISDN and CAS traces - applicable only for
Trunk-related filters.
Note: This parameter is not applicable when 'Filter Type' is set to
IP Trace.
57.5.1 Filtering IP Network Traces
You can filter Syslog and debug recording messages for IP network traces, by setting the
'Filter Type' parameter to IP Trace in the Logging Filters table. IP traces are used to record
any IP stream, according to destination and/or source IP address, or port and Layer-4
protocol (UDP, TCP or any other IP type as defined by http://www.iana.com). Network
traces are typically used to record HTTP.
When the IP Trace option is selected, only the ‘Value’ parameter is applicable; the 'Syslog'
and 'Capture Type' parameters are not relevant. The 'Value' parameter configures the
Wireshark-like filtering expressions for your IP trace. The following Wireshark-like
expressions are supported:
Table 57-6: Supported Wireshark-like Expressions for 'Value' Parameter
Expression Description
ip.src, ip.dst Source and destination IP address
ip.addr IP address - up to two IP addresses can be entered
ip.proto IP protocol type (PDU) entered as an enumeration value
(e.g., 1 is ICMP, 6 is TCP, 17 is UDP)
udp, tcp, icmp, sip, ldap, http, https Single expressions for protocol type
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.dst==10.8.0.1/16

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:
