Half 3 of the four-part collection – Cloud Monitoring for Cisco Catalyst Switches

Welcome again to the third weblog in our collection about cloud monitoring for Cisco Catalyst 9000 switches.

My final weblog was about community visibility by the Meraki dashboard. On this weblog, we’re going to take it a step additional and discuss how cloud monitoring to your Catalyst switches will assist with community troubleshooting.

I labored in buyer assist again within the day.

Most of our calls went one thing like this: “Hello, that is Pat, I can’t entry my recordsdata” or “My web isn’t working.” Basic, proper?

Talking of basic, listed below are some typical approaches to troubleshooting Pat’s drawback:

  • Prime-down: Dig by each display screen and each administration console you’ve bought
  • Backside-up: The identical as above, however beginning with the person
  • Divide and conquer: All arms on deck; cut up out your administration consoles and areas of the community
  • Observe the trail: The place did it come from and the place is it going?
  • Spot the variations: Take a very long time to look by logs to see should you can collect sufficient data
  • Transfer the issue: Pat known as again and stated they’re related—no drawback and now not MY drawback! Kick that challenge down the highway as a future me drawback.

The BEST view within the dashboard is the organizational abstract. It is a fast method to see your whole org—not simply community—from one display screen, trying on the total well being. It’s really easy to see the place an issue could also be and get to it instantly. Somewhat than flipping between administration interfaces and networks, you may get to the basis trigger nearly instantly, from anyplace in your org.

Occasion Logging

Whereas we don’t get pleasure from occasion storms and getting notifications each second of on daily basis, it’s good to log in to your dashboard occasion and be capable of have a look at occasions and add notifications should you’d like. I’m a fewer-is-better type of gal myself.

Community Well being Standing

My favourite web page particular to switches is the brand new overview—one standing web page to rule all of them!

Determine 4. Community topology within the Meraki dashboard

If we need to get to a network-level challenge, we are able to get there from the organizational alerts web page or from the community topology. That monitored swap, whereas it’s not having a critical challenge, reveals as yellow. Let’s see why it’s sad.

As straightforward as one click on, right here’s the wrongdoer:

We all know VLAN mismatches aren’t an enormous deal, however with a single click on you may see the difficulty, and another click on will get you to documentation that reveals learn how to simply repair it. Shameless plug: If this swap had been Meraki managed, you’d see a hyperlink that asks should you’d like to repair it. Click on the hyperlink and it’s fastened. Machine studying for the win!

One other of my favourite new dashboard choices is the Switching Overview web page:

That is nonetheless from a community stage and reveals you the standing of your entire switches, alerts, purchasers on the switches, occasions, Energy over Ethernet (PoE)/knowledge utilization, and swap port data.

For switches, the next choices can be found:
