Re: help extra ethernet connection for a 2501!! [7:2187]
It may be that it is actually a 2501 and the serial link is attached to a terminal adapter (we used to do this with JTEC TA's in them thar good ole days the micro channel switching type (ts013) in the land of Oz) which would give the ISDN connectivity. Either way then the answers below are still valid (ie what Jenny said) BTW - I wonder when Cisco will finally change its recommended Australian type to net3/net5 - the ETSI standard. The old switch type is still in its latest books and manuals - has anyone told the yet? Take care all - [EMAIL PROTECTED] wrote: Doesn't sound like a 2501 to me - they don't have BRI interfaces. Did you mean a 2503? I'm not quite clear on your setup, but anyway... No, you can't use a serial interface to connect to a LAN. No, you can't add more LAN interfaces to a 2500 series router. They are fixed config, not modular. Can you connect to the 'outside world' using a cross-over cable to a serial port in the 'outside world' perhaps? Or is your 2500 in the outside world?

RE: help extra ethernet connection for a 2501!! [7:2187]
There is no such thing as a serial to Ethernet adapter. It's either 2 IP addresses to e0, no internet access, another router, or setting up a win2k box with dual NICs and enabling IP Forwarding (routing). The only stipulation is that the one particular Win2k box will be plugged into the production lan ETHERNET segment. If finding funding for another router such as a 1005 with a serial and ethernet interface is nigh on impossible, it may be time to reconsider where you are working.. especially if it is required to support confidence in the health state of the production network. A 1005 shouldn't cost more than $300USD.. how expensive is an hour of downtime on the production network worth? 4 hours? 8 hours? It's simple business politics and accounting.. time to learn how to justify testing gear cost.

[7:2187] ok heres another spanner in the works so to speak, how about if I setup one of my win2k boxes as a router (in the test Lan) and via a couple of serial to ethernet adapters (with a 10baseT crossover cable in between) connected it to the serial connection of the cisco router? surely if feesible that would make more sense than binding two ips to one ethernet card, (basically i dont want any packets taking a short cut from the test lan to the production lan) i know this scenario is far fetched but trying to get funding for such a minor project such as wan traffic is nigh on impossible!! some people have no idea!! cheers Dan -Original Message- From: Trevor J Corness, CCNA To: 'Dan Pearson' Sent: 29/04/01 18:18 Subject: RE: help extra ethernet connection for a 2501!! [7:2187] it is possible, but not advisable in an undetermined lab environment. A chattering win2k box could cause problems for your production network. Given limited resources though, I suppose you could do it. conf t int e 0 ip address 192.168.1.0 255.255.255.0 (Production Network) ip address 192.168.100.0 255.255.255.0 secondary (Win2K Lab) would be sufficient. This would also allow ip routing between the Win2k lab, and the production network. Running 2 LANs off of 1 segment though, you are making all of your production network machines look at the MAC address broadcasts from your lab. If both are of a substantial size, it may create a performance issue on your production network. It is really a design issue.

[7:2187] You can not add any interfaces to an existing 2500-series router.. and like Jenny said, this sounds more like a 2503. Another possibility, would be to find another 2501/2503 router, use a back-to-back serial, and use the ethernet on that router to your lab.

Re: help extra ethernet connection for a 2501!! [7:2187]
just to stir the pot a little... :-) He could have a 2524 which has one ethernet port and one ISDN port and then there are two slots for modules - so one version of 2500 is modular :-) Unfortunately they are WAN modules not LAN modules so it still doesn't help the poster get another ethernet port. The poster could get an el cheapo 1005 or 3102 from eBay, connect the 2 routers back to back on their serial ports and then have the required ethernet port. The only reason I can see for not joining the lab to the present ethernet is to keep it separate from production facilities. However, if the lab gets chatty it could still affect the single router. (which could affect production) Anyway, any number of ways to do this from a second router to access lists.

Re: help extra ethernet connection for a 2501!! [7:2187]
Hi Dan; The easiest way is to set up secondary IP address in your Cisco 2501. I guess your router is Cisco 2503, not 2501, it does not support modular like cisco 1600, 1700, 2600, 3600 Series, etc. Hope this help Vincent Chong Dan Pearson Hi, I am setting up a test lab environment for a windows 2000 migration and want to have access to the outside world, the problem is we have a 2501 router which currently has the bri and ethernet interfaces in use, I need another ethernet interface for the test LAN, is there anyway I could utilise the serial connections for the test LAN?
