HI All, I need some help. First of all i'm no network guru, I don't understanding subnetting or subnet masks. I have been given the task to redesign our network. I know currently our network is all Class A, 10.x.x.x, 255.0.0.0 addresses. We have one router which connects us to our facility in Alabama. We have a Juniper box which connects us to the Wan. The other day someone looped one of our IP phones and basically took down the whole network until I found it. We have Dell switches which I want to replace because quite frankly they suck and offer no management options. I know on a few Cisco switches we have it disabled the ports on them because of all the traffic. Alright enough complaining on to my problem. We have about 15 IDF panels in our plant, all of them have one switch and fiber connections that go into our server room. My main issue is nothing is labeled and they have ran cabling from these IDF panels all over the facility, in other words it's not a safe bet to assume they ran what would be obvious runs to the appropriate/closest IDF panel. I am assuming because of this VLANs would be very hard to implement. How can I segregate all this traffic and get everything off the Class A network scheme? I understand Class A is a big con. How are the Procurve line of switches? Any advice or sample maps would be great. Thanks, Greg greggap@comcast.net
