If an object type is not defined, the host value is assumed.
2. dir—defines the direction towards the object. This may have the following values:
src (object is a source),
dst (object is a destination),
src or dst (source or destination),
src and dst (source and destination).
If the dir qualifier is not defined, the src or dst value is assumed.
To intercept traffic from the any artificial interface, the inbound and outbound qualifiers
can be used.
3. proto—defines the protocol the packets should belong to. This qualifier may have the
following values:
ether, fddi1, tr2, wlan3, ip, ip6, arp, rarp, decnet, tcp, and udp.
If a primitive does not contain a protocol qualifier, it is assumed that all protocols
compatible with the object type comply with this filter.
In addition to objects and qualifiers, primitives may contain arithmetic expressions and keywords:
 gateway,
 broadcast,
 less,
 greater.
Complex filters may contain a set of primitives connected with logical operators and, or, and not. To
reduce the expressions which define filters, lists of identical qualifiers may be omitted.
Filter Examples
dst foo—filters the packets which IPv4/v6 recipient address field contains address of the foo host.
src net 128.3.0.0/16—filters all Ipv4/v6 packets sent from the specified network.
ether broadcast—ensures filtering of all Ethernet broadcasting frames. The ether keyword may be
omitted.
ip6 multicast—filters packets with IPv6 group addresses.
For detailed information on packet filtering, see specialised resources.
 Launch—begins data collection.
 Finish—finishes data collection.
 Restart—restarts the utility and begins data collection again.
The Files and Folders section in /tmp/log contains a list of files in the corresponding /tmp/log directory.

PCM–dump Utility Settings
РСМdump—a utility to intercept and analyse signal traffic via E1 streams. The device enables PCM-
dumping either for a single or for multiple streams; for a simultaneous PCM-dumping for multiple streams,
