We have a dedicated VLAN for our management network here, its on its own subnet 192.168.128.0
Switch Management, UPS management and anything with a management IP all have IPs on the subnet.
Some of these devices are spread around not only our HQ, but remote sites that are connected via 200mbps microwave network, and soon VPN end points will have devices that I need to manage
My though is that, having VLAN128 presented to remote locations may cause issues with broadcasting across the network un necessarily, over the microwave not a huge issue as the speed is there, but over slow DSL VPN tunnels it may cause issues
Am I right in thinking the above and should each site really have its own management VLAN and subnet assigned, and the vlan 128 remain for the HQ only? or is it that its only for management of devices, spreading that vlan across all sites is OK?
it is worth noting that all current VLANs use our core switch back here at the HQ too as their “router”
