RE: Can 10Base2/5 be connected with FDDI ? [7:27352]
Basically you're asking if Ethernet can be connected to FDDI. Sure, if you have a hub that has Ethernet connections (10Base2/5/10/100) with a FDDI uplink. I seem to remember that Cabletron (now Enterasys) used to have a switch with this possibility (I think it was a 2200 or 2400 series). That answers the "How?" now for the "Why?". Since these are two different framing types (Ethernet and FDDI) you need a bridge. FDDI's frame size is much larger than Ethernet and therefore a bridge is needed to be able to interpret between the different frame sizes. I don't believe Cisco sells a device with these specific interface types in one box. Could be wrong, but...The Cabletron box used to cost about $2500 list for this solution. Could be worth a call to Portland. ccie1ab -Original Message- From: Charles Mao [mailto:[EMAIL PROTECTED]] Sent: Monday, November 26, 2001 1:26 PM To: [EMAIL PROTECTED] Subject: Can 10Base2/5 be connected with FDDI ?

See the following URL for a high level overview of FDDI. It states that there is a copper twisted pair medium allowed. I'd suggest a search on google to define exactly what the spec states. http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/fddi.htm > -Original Message- > From: Charles Mao [mailto:[EMAIL PROTECTED]] > Sent: Monday, November 26, 2001 12:26 PM > To: [EMAIL PROTECTED] > Subject: Can 10Base2/5 be connected with FDDI ?

Re: Can 10Base2/5 be connected with FDDI ? [7:27352]
Dont know how many devices will do FDDI. I have a feeling the Cat5000 has modules for it and I'm sure I remember a 4000 with an FDDI module in it. There are/were probably many more if you search around. Question is probably which ones are still available, and what kit you already have.

That might solve the physical-layer connectivity problem, but you would still have a problem with signal encoding, framing, media access control, frame sizes, etc. They are two different technologies. To connect them, you need a bridge, switch, or router that has both an Ethernet and an FDDI connector. You might be able to find a low-cost bridge that does this on E-Bay (or maybe a new one at BlackBox or some such vendor). FDDI also requires a concentrator. If the goal is to learn FDDI for CCIE tests, maybe books are best!? ;-) Priscilla >I'd suggest a search on >google to define exactly what the spec states. >http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/fddi.htm > > > -Original Message- > > From: Charles Mao [mailto:[EMAIL PROTECTED]] > > Sent: Monday, November 26, 2001 12:26 PM > > To: [EMAIL PROTECTED] > > Subject: Can 10Base2/5 be connected with FDDI ?

RE: Can 10Base2/5 be connected with FDDI ? [7:27352]
What is interesting to me is how I read the question as opposed to others. My understanding was that he wanted to run FDDI end to end over thin or thick coax. The layer two protocol was FDDI. At question was the acceptability of the media. > -Original Message- > From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] > Sent: Monday, November 26, 2001 3:04 PM > To: [EMAIL PROTECTED] > Subject: RE: Can 10Base2/5 be connected with FDDI ?

Re: Can 10Base2/5 be connected with FDDI ? [7:27352]
See what you mean now I read it again, but if you expand the abbreviation: FDDI - Fibre Distributed Data Interface the answer to whether it can be passed over copper seems more obvious. CDDI - Copper Distributed Data Interface may be the way if the question was "Can the technology pass over thin or thick coax", but from what I remember, CDDI used (at least) two pairs (but I wouldn't argue that point), so coax is out.

RE: Can 10Base2/5 be connected with FDDI ? [7:27352]
He didn't say coax cable. He said 10Base2/5, which are Ethernet technoloiges that use coax cable. I don't think you can run FDDI over coax cable. (Consider what the F stands for! ;-) CDDI supports FDDI's MAC layer using UTP cabling. Reading between the lines, I think he is trying to get some FDDI practice on a router that only has Ethernet interfaces. This would be like trying to take an airplane from a train station. In some (mostly non-USA unfortunately) cities, there are terminals that support both airplanes and trains. In some networks, there are devices that support both FDDI and Ethernet. They are called bridges, switches, or routers.
