Filtering by WAN DLCI
If you have deployed one of Network Instruments WAN Probes or Systems (or you are
post-filtering a packet capture obtained from such a setup), you can filter by DLCI
number.
Filtering by WAN Port
If you have deployed one of Network Instruments WAN Probes or Systems (or you are
post-filtering a packet capture obtained from such a setup), you can filter by WAN Port
number.
Filtering by WAN data flow direction and congestion control packets (WAN
Conditions)
If you have deployed one of Network Instruments WAN Probes or Systems (or you are
post-filtering a packet capture obtained from such a setup), you can filter by WAN data
flow direction (i.e., DCE, DTE, or any direction). In addition, you can add WAN traffic
management conditions to the filter rule (forward congestion, backward congestion,
discard eligibility.) The conditions are chained by logical ORs. For example if you set
direction to DTE and check all of the option boxes, you will filter for DTE packets that
have the forward congestion, backward congestion, or discard eligibility bit set.
