standard network analysis. For encapsulations that do not use DLCI
(such as X.25), the correct address value is shown even though it is

If you are looking to identify additional top talkers beyond the
DLCI, using Ethernet Top Talkers may be more beneficial for

WAN Filtering
In addition to the standard Observer packet filtering rules (station
address, pattern matching, etc.), there are two WAN-specific filtering
rules available for use with WAN probes:
Q
DLCI Address, which lets you enter the number of the DLCI
address you wish to include or exclude.
Q
WAN Conditions, which let you include or exclude frames
based on flow direction, forward and backward congestion,
and discard eligibility.
To create a WAN filter rule:
1 Choose Actions → Filter Setup for Selected Probe.
2 Select an existing filter or click New Filter to create your own.
See the filtering information in the Observer manual for full
details about creating a custom filter from scratch.
