Network Engineer. I fix outages I caused.

Labs, packets, and bad ideas

I don’t troubleshoot networks.
I ask them questions
until they admit it was Layer 1.

The config worked in the lab.
Production said,
“That’s adorable.”

Router on a Stick sounds fake… but it isn’t.

If or inter-VLAN routing ever confused you, this is the concept that usually makes it click.

What CCNA doesn’t warn you about:

The configs are easy.

It’s the pressure of touching production that hits different.

Speed breaks things.
Verification saves careers.

I labeled the port correctly.
The cable identified as a different port.

My network isn’t broken.
It’s just expressing itself creatively.

Routing without a router sounds wrong…
until you understand SVIs 👀

Routing Without A Router? https://t.co/Z7NuqSwORN via @YouTube

[Sam Arif @NetEngSam]

I made a small change.
The network made a big decision.

I like my configs like my jokes.
Simple.

What the F**k is a VLAN? https://t.co/zUMNisZ9mK via @YouTube

[Sam Arif @NetEngSam]

I fixed the outage.
Then I realized it fixed itself
and I just showed up on time.

[Sam Arif @NetEngSam]

I don’t memorize commands anymore.
I memorize what not to touch.

[Sam Arif @NetEngSam]

I thought I understood VLANs.
Then a trunk disagreed.
Now we don’t speak.

Rule #1 in network engineering:

Never say “Hopefully no outages today.”

#Cisco #CCNA #Networking #NetworkingEnginner #PaloAlto #Fortinet #IT

[Sam Arif @NetEngSam]

What CCNA doesn’t warn you about:

The configs are easy, It’s the pressure of touching live production that hits different.

#CCNA #Networking #NetworkEngineering

[Sam Arif @NetEngSam]

Always double check configs.

Production doesn’t care how confident you felt.

When you first get into networking, no one tells you about the anxiety of an outage when you’re on weekend rotation.

VXLAN finally made sense when I realized it’s just Layer 2 traffic wearing a Layer 3 disguise.
