Ethernet Interfaces
The checkboxes under this heading select the Ethernet interfaces over which packets are
captured and included in the analyser trace.
Raw SYNC Sources
The checkboxes under this heading select the synchronous sources over which packets are
captured and included in the analyser trace.
DSL PVC Sources
The checkboxes under this heading select the ADSL ATM PVCs over which packets are
captured and included in the analyser trace.
PPP Interfaces
The checkboxes under this heading select the PPP interfaces over which packets are captured
and included in the analyser trace.
IP Sources
The checkboxes under this heading select the IP sources over which packets are captured and
included in the analyser trace. These sources include IP packets transmitted and received over
Ethernet, PPP and OpenVPN (OVPN) interfaces. It is also possible to select GRE Tunnels via the
advanced sections of the individual GRE Tunnel configuration pages.
IP Options
Trace discarded packets
Enables or disables the capture of packets that are discarded by an interface along with a
reason for why the packet was discarded.
Trace loopback packets
Enables or disables the capture of IP loopback packets.
IP Packet Filters / Discarded IP Packet Filters
TCP/UDP Ports
This parameter filters out TCP or UDP packets with particular source or destination port
numbers. The format of this parameter is a comma-separated list of port numbers. For
example, you may wish to exclude the capture of Telnet and HTTP traffic that would otherwise
swamp the data of interest. This can be done by entering
23,80
for this parameter. Conversely,
you may want to capture traffic on a specific source or destination port only. To do this, use a
tilde (
) symbol before the list of ports. For example, to only capture Telnet and SSH packets,
enter
22,23
for this parameter.
IP Protocols
This parameter is used to filter out IP packets with particular IP protocol numbers. The format
of this parameter is a comma-separated list of protocol numbers. For example, you may wish
to exclude the capture of TCP traffic that would otherwise swamp the data of interest. This can
be done by entering
6
for this parameter. Conversely, you may want to capture traffic with a
specific IP protocol number only. To do this, use a tilde (
) symbol before the list of protocol
numbers. For example, to only capture UDP traffic, enter
17
for this parameter.
