Fun in the Lab: IWAN, LiveAction, Prime, UDP Director

Fun in the Lab: IWAN, LiveAction, Prime, UDP Director

Okay… so just some major geeky fun in the lab.  I had lots of fun doing it… so why not share it with you and let you in on some geeky fun? Thirty-eight minute YouTube with a PDF guide book. 🙂  Little bit of this… little bit of that.

  • Lancope UDP Director,
  • LiveAction,
  • Spirent TestCenter,
  • IWAN
  • Prime.

Pdf of slides

Breakdown of YouTube sections and corresponding approximate timestamps:

  • Overview – start til ~6 minutes in
  • IWAN Policy & Status – 6:10 til 14:20
    • Check IWAN MC Policy & Status
    • At Store1 check IWAN status
    • Check traffic – EF & CS1
  • Monitoring Traffic Flows: 14:20 til 20:20
    • In LiveAction see the traffic flows
    • In Prime’s new IWAN PfR monitoring look for traffic flows
  • Lancope UDP Director & Troubleshooting: 20:20 – 27:20
    • Troubleshoot in Lancope UDP Director
    • Find missing forwarding rules
    • Fix missing forwarding rules
    • Sniffer Capture
  • Monitoring Traffic Flows : 27:20 – 28:20
    • In Prime see the traffic flows
  • Impairment & Traffic Flows: 28:20 – 38:00
    • Cause delay on MPLS at Store 1
    • Verify LiveAction, Prime and CLI all see the same

 

 

My Current IWAN Analogies

My Current IWAN Analogies

I use analogies. Just how my brain works…. and how I sometimes learn and teach.  Token-ring source-route bridging analogy was “breadcrumbs thru the network”. Analogy for DLSw+ was a boat getting the breadcrumbs over water between 2 islands. I think I like analogies cause…. to be superbly honest… when I came to work at CiscoContinue Reading

Fun in the Lab: Troubleshooting DMVPN Per-Tunnel QoS

Fun in the Lab: Troubleshooting DMVPN Per-Tunnel QoS

In Playing in the Lab: DMVPN and Per-Tunnel QoS  we looked at DMVPN per-tunnel QoS. We looked at how to configure it…. how the vendor private extensions in RFC2332 are used in the NHRP registration request… and how to see, via show dmvpn detail which DMVPN spokes have per-tunnel QoS applied to them.  If you haveContinue Reading

Business Critical Apps & the DMVPN Underlay of IWAN’s Intelligent Path Control

Business Critical Apps & the DMVPN Underlay of IWAN’s Intelligent Path Control

Let’s assume we have a Branch with 1 Router and 2 WAN connections.  We decide to use Intelligent Path Control with PfRv3 and design our policy such that the business critical traffic goes over one of the WAN clouds (MPLS, for example) and will use the other WAN cloud (Internet, for example) should a certainContinue Reading

Which Path in the WAN are those Business Critical Applications Taking?

Which Path in the WAN are those Business Critical Applications Taking?

“Learning about and avoiding impairments (delay, loss, jitter) along the path that business critical traffic takes.”  That is what I wrote in my previous blog “IWAN’s Intelligent Path Control & Using Your Backup Link.”  But how is that possible to do? Thinking some type of probe? From where to where? Thinking the WAN edge links?Continue Reading
