Maintenance & Support

Hi All, how do you all manage maintenance and support?

we currently have a supplier that provides us Cisco support for around 400+ switches & 100+ Routers this Cisco SmartNet cover so we get options for 24x7x4 or nbd with/without engineer ...all the normal bits

the problem we are having is when renewals are coming up...are devices are really badly inventoried so we have to hunt though all these switches looking for serials on stacks to make sure everything is covered we have SolarWinds which monitors what people have added but then we have missing devices and to detect stacks thats a different reports - we also have Cisco AI monitoring that does not pick up out whole estate either

from the maintenance contract that we have coming through we are working out the last renewal only covered around 60% of all hardware

we are UK based with European offices and I am wondering is anyone knows of some sort of blanket coverage if we say we have roughly 500 devices we want covered 27x4x4 with a flat price no matter what the device is

anything like this around?
