Just thought I would try and get some input on a problem i have at the moment:
(Most) of our printers and older switches (Ones that I didn't install) are currently on an IP range of 192.168.x.xxx ranging from 100 to 300 and a subnet of 255.255.252.0
Now I don't think this is correct. Firstly that subnet is not valid for that IP address range and I have also noticed some very strange things starting to happen now that I have turned STP (Kids know that broadcast storms break networks without it turned on now).
Firstly our STP new managed switches are on our 'normal' IP range of
172.xx.xx.xxx and a subnet of 255.255.252.0. I have set allocations for these in DHCP and from there I can see what devices has what IP. I have also noticed that the devices are quicker than he ones on the private subnet both in terms of say printing or loading up web interfaces in IE for management.
I have run ethereal to see what the switches are doing in the way STP path resolution and there seems to be a couple of seconds if not more in terms of latency in resolution of private devices. Sometimes i also see complete failure in communication with the device VIA web interface.
To my way of seeing it we don't actually have anywhere to see what device has what IP address. I have tried to explain that putting them on the same IP Address range and subnet will boost performance of these devices but I don't seem to be getting anywhere except 'It was installed by RM that way'
Anyone got any thoughts/How you do it (All comments appreciated, Even if you are CC3 OR Vanilla) on this as I don't want to keep pushing it if I am not accurate, After all the people I am challenging on this could be right, And knowing my luck me be wrong.
