Quick Question for you guys. Hopefully its not a silly one.
We have a 48GB Switch in the DC. It was an old HP Procurve. We replaced with a UNT Edge Switch. Really nice bit of kit for the money! its not bad considering the price and what you get! But anyway!
We have a bunch of servers connected off of it, Dell Servers, NUCS other routers etc. etc.
When we had some downtime, to replace the old HP Procrove, we mapped all the Vlans etc and configs on the new switch. Unpatched all the ports and quickly punched them into the new switch.
Everything works, some devices come up, but others were struggling, we spotted to weird Looping going on our main core, and some devices just didnt work.
We fixed it by simply disabling the port on the core router and enabling it again, and the other nodes which that didnt work, we simply rebooted.
My question is, why do some devices decide not work properly? Is there some kind of old Cache or ARP going on, and it needs a clear out? When replacing a switch surely you should be unplug, and plug in a new one, regardless or make etc.
Thanks in advance.
