Network Hardware Refresh Policy
The company that I work for is looking at creating & implementing a network hardware refresh policy as they do not have one currently. What types of guidelines are used in your policies when it comes to upgrading or replacing Cisco hardware on your networks? We talked about 3 or 5 years for switches, routers etc. and possibly end of life/end of support for other devices. Just looking for what other people use as a determining factor in this area. Any input would be helpful.
