recommends two dedicated network switches for two Private console LANs.
Did you provide two dedicated switches? One dedicated switch and one
networked LAN switch? Two networked LAN switches?
If you dedicated nework switches, then it seems like you also need
separate power circuits for each switch and at least two console
workstations need to be on different power circuits also.
What is the most common practice? I am trying to balance cost and ease
with good console reliability.
Dedicated switch is recommended beacuse of LAN separation. It's not
matter of dedicated device. It's a matter of physically separated
network. With own cabling and hub/switch.
It is recommended because of security reasons.
If your LAN is built on "enterprise switches" with VLAN facility, then
you don't have to provide separate physical devices. Again, if you
consider your network as very well secured, then you don't have to use
separate one. Especially, when some rules are applied on the routers.
BTW: ICC session definitions could be "open" or "IP-dedicated". The last
case means only predefined (by you) IP address can establish session. In
well managed network, assuming the address is in the same net, security
is OK.
Regarding to power circuits: I'm pretty sure there are NO SPECIAL
requirements for that. If you don't have problems with LAN and power
circuits, then you won't have it with ICC as well.
