How often do you replace switch gear?
We have an interesting problem here where our switches would have been covered by a lifetime warranty, but they were bought in the name of our old managed service provider. So, although they're only 3 years old, they're all out of warranty!
We have around 20 Cisco edge switches and 2 units which make up our core (3560-48/24 models for edge, mixed with 2960-48/24s, and 3750s as the core).
So, its all good gear but a lack of warranty is worrying somewhat.
How often do others replace their switch gear? Especially if it is out of warranty?
