Our Desktop team is planning to upgrade 40sh PCs remotely over a 10 MB link. I argued that this may cause issues since the link is only 10 MB considering the amount of PCs they are trying to upgrade.
They will still go ahead with it since this was approved by a manager, the argument was that this will be done after hours and we will see how they will get on in the morning!
I'm planning to clear the counters so that I can check first thing in the morning if there were any errors, ....etc.
I'm just wondering what will happen when a link is over-utilized and cannot take the load? I assume that packets will be dropped and connectivity issues will occur?
Also, any other useful commands that may help other than the sh int?
Would like to get your opinion on this plz.
If you have no QoS strategy there, regarding packet congestion, packet prioritization or shaping, when the link is full then the packets will be delivered by FIFO method (first-in-first-out). The rest of the packets which cannot be delivered right away, will be queued. When queue is full, the packet will be dropped (tail dropping effect). This is the technical explanation.
What your Desktop team will see is that they will lose connection to their remote systems (PC) or encounter delay in command processing. You also will have problems reaching your remote network devices if you have any.
As a suggestions, why they don't split these 40 PCs over multiple days, depending on the upgrade size / PC. In this way, they might have a chance to do it.
