ThousandEyes in Catalyst 9000 Switches, Half 2: The right way to set up the agent utilizing Cisco DNA Heart?


Half 2 of the 3-part ThousandEyes in Catalyst 9000 Switches Collection: The right way to set up the agent utilizing Cisco DNA Heart?

Within the first a part of this weblog collection, we coated the advantages of putting in  ThousandEyes Enterprise Agent in Catalyst 9300 and 9400 Switches. Readers may now be all in favour of turning on this functionality on present switches and this weblog will clarify how.

There are two choices for deploying ThousandEyes Enterprise Agent in C9K Switches. The primary possibility is handbook utilizing CLI. The second possibility is automated utilizing Cisco DNA Heart. When deploying ThousandEyes agent is one or two switches, CLI could be a good place to begin. Nonetheless, utilizing CLI for a lot of switches will be time-consuming and troublesome to take care of. On this case, Cisco DNA Heart is the best software because it, not solely streamlines the set up course of but additionally takes care of the appliance lifecycle administration.

The place to begin?

  1. Acquire your ThousandEyes account – The weblog won’t cowl this step. I like to recommend working together with your Cisco or Cisco Accomplice consultant to acquire entry to the ThousandEyes dashboard
  2. Pre-work – Outline IP addressing, perceive proxy necessities and collect the ThousandEyes token
  3. Outline HTTP(s) credentials in Cisco DNA Heart for the precise gadgets
  4. Comply with the “App internet hosting for Switches” workflow in Cisco DNA Heart
  5. You’re completed! Your infrastructure is able to add the exams and revel in your enhanced visibility.

Pre-work

ThousandEyes Enterprise Agent is put in in an software internet hosting atmosphere in a Catalyst 9300 or 9400 swap. The set up requires sure parameters which embody an IP tackle inside a Layer-2 VLAN within the atmosphere. This VLAN has to have energetic ports.  As well as, we require the masks, gateway, VLAN and different parameters. For a seamless set up course of, I like to recommend making a doc with all this information for each swap that can host ThousandEyes agent.  The picture under exhibits an instance of the desk I put collectively for the set up in a Catalyst 9300 swap in my lab.

The appliance internet hosting infrastructure, requires a set of configuration settings within the type of “Docker Runtime Choices”.  The primary runtime choices are:

  • Account Group Token: Distinctive string that permits the binding of an enterprise agent to the ThousandEyes account. This token is essential for the set up
  • Hostname: Identify of the Enterprise Agent that can seem within the ThousandEyes dashboard. We will use the swap hostname or one other string of our selection.
  • Proxy: That is non-compulsory. Used if the group makes use of a proxy

To acquire the Account Group Token, entry the ThousandEyes dashboard as proven within the picture under:

Outline HTTP(s) credentials in Cisco DNA Heart for the precise gadgets

DNA Heart requires HTTP(s) credentials to hook up with the Utility Internet hosting infrastructure. These credentials must be specified within the Cisco DNA Heart stock.

Comply with the “App internet hosting for Switches” workflow in Cisco DNA Heart

Watch the video under to entry the demo displaying the workflow:

You accomplished the set up! Your infrastructure is able to add the exams and revel in your enhanced visibility.


What’s subsequent?

Weblog #3 will cowl set up utilizing CLI.
