Convert serial port to ethernet for 2500 model

[hummer3331973]

Hi-

I have a number of old 2500 models with 2 Serial interfaces and 1 ethernet/AUI port.

I have an application that requires 2 ethernet ports. Do you know a box that can convert one of the serials to Ethernet?

Thanks.

the only application i know that could do that is ebay..
seriously.. you can look for a cheap 2611 or something or 2514 if you want to do it on the cheap...

For some reasons, the old person doing this keep 5 pcs 2501 hidden on the stockroom. And here I am trying to impress my manager

What application requires 2 ethernet interfaces? Perhaps if you can provide us more information we can come up with a solution.

It's a typical gateway set-up where you'll connect 2 subnets from different sites without using T1s.

But this is more of putting these old units into something useable than just a paperweight.

Seeing that the 2500's have been End of Lifed and End of Serviced, I wouldnt attempt to put them into production just for the sake of doing so. How is the other site connecting if its not with a T1?

Here is a link to a serial to ethernet converter. I use it all the time:

(The 1 - 8 signifies number of com ports, so you can convert up to 8 signals to ethernet with a I-7188E8.)

Why not use two 2501's as frame relay routers, and one as a frame relay switch???

--subnet1----e0/2501---s0/2501----frameswitch----s0/2501---eo/2501---subnet2

That's how I used to do things with many routers, but only one ethernet interface on each---had adsl going from the modem to the fa0/0 on a 2620, then s0/0 to a 2503 (frame switch, frame relay connection to it), then the other end to a 2620 s0/0, and fa0/0 to a Cat2924 switch to my home network. My adsl speed was 3MBps, and it bottlenecked at 1.5, so I played around a virtual-access setup to aggregate bandwidth between two serial interfaces and got 3MBps throughput, and no frame switch...
modem--R1fa0/0---R1s0/0.1-------R2s0/0.2----R2fa0/0---Cat2924---pc

So you could do it that way. I think either way would impress your boss---use two 2501's to get one big router with four serial interfaces and two ethernet interfaces. You would have four separate networks, but you could do things like static routing and no spanning-tree on the switch to cut down on latency.

Thanks for the help everyone, I'll try those converters first. I'll also take a look in your frame relay, burtsbees.
