How to Terminal Server?

[imran_mcse]

What is terminal Server, How can i build it to access all my cisco router's console ports from one location.

Can it be established with 2522 Router.

A 2522 is what I use in my lab. It has 2 sync serial interface and 8 or 9 (i think) async serial interface which run at no more than 115kbps. You will need a special cable to convert the DB60 pin interface on the router to a RJ45 end to console into each of your individual routers. Here is what I have used..

2522--db60---rs232(M)-rs232(F)adapter--RJ45--Console

The 2522 has db60 interface. I bought some Db60 to RS232 cable for cheap prices from Ebay (that was a while ago)..Bought some RS232 to RJ45 adapters (You used to get these 25 pin adapters with Cisco Catalyst 5000 and 7500 series routers). At the end of the RS232 connector on the cable, I connected the 25 pin adapter and then used a regular Cisco rollover console cable (Blue or Black) to connect to each Cisco router. On each of the serial interface of the 2522 you have to give this command...

int s0

physical-layer async

After this command each of the serial interface will appear as a TTY line. ("show line")

line 36 48

transport input all

int lo 0

ip add 1.1.1.1 255.255.255.255

ip host R1 2036 1.1.1.1

ip host R2 2037 1.1.1.1

ip host R3 2038 1.1.1.1

Bottomline is that, if you have a 2522 with you, you can make a cheap TS out of it by buying some cables and adapters. The router stack will look bulky with all the cables I mentioned above...If you want it to look neat and nice, i would suggest going for a 2509 or 2511 for the purpose. You get a 8 port or 16 port octal cable to connect to each console.

Or if you have a 2600 or 3600 router with you, you can get a NM-32A which is 32 port async module can console into upto 32 devices..But this might be probably more expensive solution..

Good Luck!
