First: How Cisco NAM can calculate server, client and Network Responses while it is not the initiator of the traffic? Does it rely on any timestamps in the data packets? Do all protocols put a time stamp in the header ?
The second questions is: how does NAM classify the clients and servers? as I can see servers appearing as a client.
Cisco Prime NAM collects packets or flows information being sent to it from the switch, router, or WAAS devices. The NAM parses the packets and flow information, gathers relevant data, computes various performance and usage metrics, and stores processed information in the new Performance Database. This database provides valuable traffic information on voice, video, and data traffic, VLANs, Differentiated Services (DiffServ) configurations, hosts, conversation pairs, application usage, and application response times. This information is presented in the Cisco Prime NAM's GUI in easy-to-read interactive reports.
There are multiple ways to gain visibility into traffic from more than one device with the Cisco NAM Appliances: • The NAM Appliances include more than one monitoring interface, which allow them to collect traffic from more than one device. • The NAM Appliances can be used with a passive inline tap to monitor traffic from/between multiple devices. • The LAN or WAN traffic from other devices can be directed to the NAM Appliances for analysis using RSPAN, ERSPAN, or NetFlow.
I am testing the new Cisco NAM 6.0 and I am triing to set up some Responce Time Results. I am using only one device Cisco 3825 as an Netflow Exporter and all other Analyses looks fine expect Responce Time. What should be done/configured in order to have a Responce time Graf Results and so on.
Question We run asr9001 with XR 6.1.3, and we have a very long delay to

Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
Hi, I am seeing quite a few issues with patch install and wanted to
share my experience and workaround to this. Login to admin via CLI, then
access root with the “shell” command Issue “df –h” and you’ll probably
