Cisco 2505, 2507, and 2516 Routers

[knudsen]

I'm confused about the built in hub on the Cisco 2505, 2507, and 2516 outers. I'm looking all over the web and can't find anything except the hub is hub. ciscokits.com says, "The Cisco 2507 Router is the same as the 2501 with the addition of a 16 port hub that is built into the unit. This is a great benefit as you don't need to spend an extra $15.00 for a ransceiver." So, does that mean I can route to it? Or is it just a dumb hub, no different than an external seperate hub sitting aside from the router? Can I telnet manage the router through one of the hub ports?

What I want to do is connect it to my two c4500 routers that have ethernet modules in them, then learn routing and all for CCNA. I also have a 1912 switch and some unmanaged switches. Is this what I need to get, or should I get a 2514 kit plus AUI transceivers? Or is there a better router to get?

As I understand it, the hub functions the same way the built in 4 port switch works on a Linksys router. Essentially, it's a router and a hub in one box. Inside the box, the ethernet interface from the router is connected to the hub.

So, it works the same way as if you had, say, a 2501 with an ethernet transceiver connected to a hub.

Thanks, Fred. Your explaination makes the most sense. I'll need a 2514 or get my 3rd c4500 going, or learn the nasty old 4.x pix os. 3rd c4500 was bought as is and won't go past ronmon, which is yet another topic.

Thunk you might like to see the lab I setup in my basement:

 

[Zakkas]

Nice setup there. I used my jobs network and some spare stuff to study for my CCNA. Some places to study hard in VLANs, Routing protocols (including OSPF and EIGRP) anything and everything, troubleshooting routing issues, and everything else hah!

And you should be able to telnet to the ethernet interface address thats binded to the hub ports.

If your other router only boots to ROMMON mode see if you can change the config register to 0x2142 and see if it boots

commands are:

confreg 0x2142
reset

 

[fredweston]

Is that a PIX up top of the stack? Hehe, I have an oldschool PIX laying around but I'm not brave enough to try and get it running. I didn't think the CCNA was overly difficult. You need to know what you're doing, but I studied for about 2 weeks and passed. Just concentrate your studies on the features you've used the least.

I'm hoping to get the midrange NP kit from CiscoKits by the end of the year. There's 2 of us at work that want it, so we're trying to justify it as a business expense. One thing I'll say about the CCNA and if you ever try for the NP is study your ISDN. That's the one thing most people never use, and I freaking hate it.

 

[knudsen]

Yup, Fred, that's an original PIX, lovely beast it is. It was only $30 delivered, but to do it again I would get a 520 with a newer PIX-OS (6.x) for about the same $ or even a 501 for $100ish if you watch the auctions. Also have a 1900 switch that for some reason won't vlan, and 3 c4500's. After my credit cards cool off a little and/or I get a job, I might get a 2900 switch and a 2500 router. I need to get another c4500 module or two to get them all talking with a 2500.

Thank you Sir Zakkas.

I was trying 0x2102, and also swapping memory around. I was under the impression that I had some bad mems after I was getting an error that I googled. So I was trying it with one memory chip pulled and/or moving mems to different slots. Both flash and RAM. The error that made me try this was similar to:

Uncompressing file:

When I pluged it back in just now I got

then it hangs.

I got back into ronmon with a break during startup and got this:

egads.

I'm having some real bad memory problems myself (no joke) and can't remember all I did, but I remember after swapping the memory around I would get thet thing where it hangs up, then a 2nd try would make it boot again.

I confreg'd as you suggested and, wait a minute, I'll be damned, it worked. End of discussion. You DA MAN! Tahnx!

BTWF: (By The Way Fred) The best bargain in that setup is the cabinet. I bough 7 of those at Purdue salvage for $10 ea. The other six are in the garage with the casters off every other one so they stack, making lovely tool cases with ball bearing slide out drawers and adjustable shelves. Screw Crapsman! Between my metal shop, woodworking, electronics and automotive hobies, they are all full already. The PC was another bargain, built from free junk. dual 400 MHz P2's. I ran Linux on it all last summer and had no problems. In the cold winter, house kept at 60 degres F, I loaded XP on it and it overheated at idle. Put a monster fan on the CPUs and they stopped setting off the bios temperature alarm, but it locked up left and right. I thot I cad damaged the CPU's. I decided to try it again with Fedora core 5 and the CPUs are cool as a cucumber with no fan. Hmmmm, is XP a resource hog?
