Re: Token Ring in home lab questions

Among other equipment, I've got an SMC MAU, a Token Ring NIC installed in a PC, DB-9 to RJ45 media filter, and a 2504. What type of cable do I need between the media filter on the router and the MAU? I know it's not a standard Cat 5 cable because Token Ring uses different pins than Ethernet. Pinouts matter not, as long as all 8 wires go all the way through (I have seen some cheap Ethernet cables with only 2 pair). Standard Cat5 straight-through cable is just fine. What about the cable between the PC and the MAU? The NIC card can handle either RJ-45 or DB-9. Same thing - Cat5 straight-through. Depending on the card, you may have to pick the RJ-45 or DB-9 via a driver setting, via a NIC config program, or with a jumper. Most of the new ones will. On the MAU, there are two ports that are labeled RO and RI with small push button switches next to them to enable or disable "wrap". What are these for? This allows you to connect to another MAU and have the ring go between them (Ethernet usually calls this 'stacking'). I'm not familiar with SMC MAUs per se, but you don't want the MAU to try and send the ring out, nor expect to see one come in. If it tries, and there is no connection to bring it back, the MAU will just push the token out of that port, and then you'll end up with them all over the floor :-). Thus the ring is broken and no stations will connect. I would *guess* you would want to "enable" wrap, and not plug anything into these ports. My reasoning is that the term "wrap" means for the RI/RO ports to wrap the ring back on themselves. If you get everything else set up, but you just cannot connect into the ring, try changing the wrap switches. Also, if this happens, try to set everything for 4Mbps instead of 16, since there are some MAUs that just don't like 16 even if they say they do. Except for the RI/RO ports, and the different connectors you run into periodically, token ring is pretty much the same as Ethernet for setting up layer 1. ---JRE--- _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: Token Ring in home lab questions
If the DB9 - RJ45 connector is a type 3, you are fine. You use a standard CAT 5 Cable between MAU and router. The Ring in Ring out is for connecting multiple MAUs together. (There's no concept of a crossover cable in Broken Ringerr Token Ring) Wrap is for management, you can configure MAUs to only allow certain MAC addresses, and if a mac address is used that isn't int the list, the port will wrap (go inactive). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Lori S Carter Sent: Wednesday, December 27, 2000 6:16 PM To: [EMAIL PROTECTED] Subject: "Token Ring in home lab" questions Dug through the archives and found very little on setting up Token Ring in a home lab.

RE: Token Ring in home lab questions
I agree with you, token ring is a nice protocol, and I have studied it at great length. I've also dealt with several very bad implementations of it, which is kinda where that term comes from. But, I have seen some great implementations of token ring, and those work beautifully. I've worked with mainly SynOptics MAU's (which are great manageable devices, if you have the right software for them). I didn't think about the unpowered MAUs, which I've only dealt with once or twice. In any case, "wrapping" or "partitioning" a port generally means to shut it off, and I could see where you would need this in an unpowered device.

Re: Token Ring in home lab questions
Hi There are two types of TR MAU (hubs) out there. One has the old block style connector, the other has a RJ-45 style port. Hopefully you have the later, if not they are real cheap on ebay. Anyway, (assuming the RJ-45 style) a straight regular old ethernet cable between the PC NIC and the hub and between the media filter and the hub. Nothing special here, a straight cable is a straight cable rather it uses the same pairs to communicate or not.

Re: Token Ring in home lab questions
Lori- it's usually very cheap easy. Funny thing (from the Ebay prices) it appears people are steering clear of Token Ring. OK- you need a MAU (which you have), 2 cables (DB9 to that funny IBM connector), or 1 cable standard cable 1 for the NIC (which can either be RJ45 or DB9). Your connection is made on the numbered ports. The R0 R1 are for daisy chaining the MAU's together. http://www.cisco.com/univercd/cc/td/doc/product/core/cis7505/ipicg/ipicgtrp. htm#xtocid40785 Here's the shpeal on the cables... Once you have two stations (I use a 2512 a 4000), just set the IP's the ring speed (4 or 16)... you should hear the MAU clicking your off to the races.

RE: Token Ring in home lab questions
I have limited exposure with TR (but more to come with my new job) but I do know a little. I believe TR uses pins 3, 4, 5, and 6 pins. Standard cat 5 will work cause the pins in the middle are lined up. RO(ring out)is where you connect the MAU or MSAU to the RI(ring in) of the next MAU/MSAU. Not sure about the mau and the router but I think you can use a standard cat 5 with the filter. (something about the high frequency of the utp) Anyway, I hope that is some help. (and I help I am right!) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Lori S Carter Sent: Wednesday, December 27, 2000 4:16 PM To: [EMAIL PROTECTED] Subject: "Token Ring in home lab" questions Dug through the archives and found very little on setting up Token Ring in a home lab.
