To check the congestion on WAN links at the data center and branch site.

A. [WAN Segment] While reports collect data, check whether WAN links at data center site are congested.

1. Go to Monitor > DiffServ > Traffic Stats.

2. Change the data source profile to focus on the SP-A data center WAN link Netflow Data Export

(NDE-DC-WANLinkIn/NDE-DC-WANLinkOut).

3. Check traffic by aggregation class.


B. Check whether the SP-A WAN link at the branch office site is congested.

Either check the router using CLI, use a third-party tool, or configure NetFlow Export to NAM-2 at DC and follow these steps:

1. Go to Monitor > DiffServ > Traffic Stats.

2. Change the data source profile to focus on the branch office WAN link NetFlow Data Export (NDE-DC-WANLinkIn/NDE-DC-WANLinkOut).

3. Check traffic by aggregation class.
