I've just set up a rack with a SFP input into a Dell N2024, with a /28 routed to the switch which I can then use as required for devices within the rest of the rack.
This is working fine from a single setup point of view, but I'd also bought an additional switch, under the guise that they'd be setup to redundantly fail over should the first switch fail. The network engineers haven't done this though as part of the original installation and now I've got to work out how to complete the redundancy setup. I've not had much experience with these switches though (or setting them up in a redundant fashion before)..
It looks like I've got two options:
- Firstly, get the switch setup how we want it, then copy it's config to the second, although it's a critical service, I'd be happy with a manual move to the switch below (i.e in the unlikely case of complete switch failure some downtime whilst the switches were swapped wouldn't be a huge issue)
- Secondly, work out how and what the process is, to set these switches up in a redundant fashion. Am I right in assuming, I'd need a second fibre in (for the SFP port the second switch), as well as dual outputs to each router/firewall? What are the technologies involved in this process?
Any help is much appreciated
