Table 62-2: 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:

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

● If the 'Value' parameter is undefined, the device records all IP traffic types.

● You cannot use ip.addr or udp/tcp.port together with ip.src/dst or

udp/tcp.srcport/dstport. For example, "ip.addr==1.1.1.1 and ip.src==2.2.2.2" is an

invalid configuration value.

Debugging PSTN Calls through CLI

You can also troubleshoot and debug digital (PSTN) calls through the device's CLI.

■ To configure the debug (trace) level: The debug (trace) level determines the level of

information included in the PSTN trace. For all PSTN traces, the trace level is configured per

PSTN interface, using the following command:

configure voip > interface {e1-t1|bri} {Slot/Port} > trace-level {full-isdn|full-isdn-with-

data|q931-raw-data}

For example:
