I know that Cisco recommends to set aside a management VLAN just for itself because you wouldn't want your management IP address on a production VLAN because if for any reason that VLAN cannot be communicated across, then you can no longer connect to it (The Switch)
My question is, let's suppose you have 3 VLANs
VLAN 1 (production)
VLAN 2 (Production)
VLAN 3 (Switch Management)
If you're always on VLAN 1 for work purposes and you're the admin, and something happens where the VLAN fails and no one can communicate, how do you access the Switch Management VLAN now that VLAN 1 (The VLAN you're always on) has failed?
I hope I'm explaining this thoroughly, but I'd like to understand what the best practice is for creating management VLANs and ALWAYS being able to access it no matter what.
