What's defined as a hot-cut?
-Using existing rack/cables?
-Do outages go hand in hand with hot-cuts? Or are outages/blackouts defined as operations 'ignoring' the flags that occurring, or is it an actual 'outage'.
What is swinging? (L3 swing, swing over L3, etc.)
-Is this 'swinging' IP schemas? Original is 10.0.1.0/24, new devices will be 10.0.2.0/24. Maybe the schema is the same? It could mean a lot of things as well, but elaborate!
If ISP is on the call with us, what are some validation commands I should ask for (QoS, MPLS, basic connectivity)? Please list!
show ip interface brief....etc.
In general a hot cut is basically a live cut. There will generally be an outage while things are cut over.
Swinging - not a general term with a specific meaning. I might use it if we are putting in a new circuit to replace an existing circuit and I would say we are going to swing over to the new circuit. I might have used the word "swing" instead of "cut" as in cut over to the new circuit.
I have never heard swinging in terms of changing IP addressing. That is usually referred to as changing your IP addressing ;)
To validate -
Make sure you can ping the connected ISP router, make sure you can ping out to things on the internet i.e. www.google.com, 8.8.8.8, etc..
Make sure there are no CRCs or errors on the circuit.
Test everything - i.e. web browsing, email, verify your hosted severs if any can be reached from the outside, etc..
