few questions

in CCNA & CCENT
First of all, I see here alot that you should use a 2950 switch to prepare for CCNA - i'm just wondering why is it that say a 2924 won't work?

next up, i read an auction stating that you could use a 2511 router as a terminal server. this may be a dumb question but does that mean i could hook the console from my router to the asynchronous serial ports on the 2511 and then access the other routers through the 2511?


i had more, i just forgot them. icon_sad.gif

    ..and I keep hearing that you don't need a switch at all to prepare for the CCNA. Can someone please clarify?

    Although, I guess it would make sense to get a switch if you are going to go after the more advanced certs (CCNP or higher).

    The 2900s will work for the CCNA..... but you'll need a 2950 for the CCNP. The 2900s don't do the range command, and you don't do Multicast or QoS in the CCNA.

    The 2509-2512 (8 or 16 Async and either Ethernet or Token Ring) use a DB68 Octopus cable to attach to the console ports.... they also have Octopus cables for modems.

    The CCNA is Routing AND Switching.... so switches are useful. 3 Switches let you lab up all you'd need for the CCNA, but you could "get by" with only 2. Don't bother with a 1900 series switch.

    I plan will be training for CCNP after CCNA classes are done, but i will also be doing some upgrades to the lab when i get there. as far as i know the CCNA will cover basic switching.

    edit: thanks for clearing that up for me, (refering to post above). I have a 1900 switch on the way but i don't plan to use it for anything. looking for 29xx switches now.

    I'll upgrade to 2950's once i get closer to CCNP classes.

    mikej412, thanks for clearing that up. Guess I'm going to have increase the amount I was budgeting for my CiscoKit. icon_cry.gif

    Speaking of CiscoKits, I'm going to buy a Dual router Kit (and a switch or 2) and was wondering if I should buy:

    Dual 2610 64M DRAM/16M Flash/IOS 12.3.19 IP/FW/IDS

    or

    Dual 3640 64M DRAM/16M Flash/IOS 12.4.12 IP/FW/IDS

    I was thinking of going with the 2 2610s since they are more affordable but, since the new CCNP exam will test your knowledge of IOS 12.4 (yes, I'm thinking ahead icon_cool.gif ), I was going to go with the 3640s. I also 'heard' that you can load the 12.4 IOS onto the older 2610s. mikej412, can you give me some advice and also clear up the IOS confusion? icon_wink.gif Sorry if that IOS question has been asked before.

    The 1900 will let you do the OSPF DR/BDR elections... and I think it does do ISL trunking (which the 2950 and the rest of the world doesn't do). And it can be the 3rd switch for STP.

    You usually want to get the EN version -- that way it already has the memory to run the Enterprise version of the software.... won't matter for the CCNA, but it may matter for the CCNP.

    so how would you use a router like a 2511 as a terminal/access server? would you configure it and then telnet into it from a computer and then access the other routers from there?

    Yep... configure and telnet and then access the other routers from the 2511

    great link, thanks. i will pick on up next time i see a good deal for one (w/ cables) on ebay.

    edit: lets expand on this. say i want to access this over the network via my laptop. i have a wrt54g linksys router/4port switch. so, do i connect the router to the switch via ethernet, configure it with a 192.168.1.x ip, and then should be able to telnet to the router and then get into routers connected to the 2511, right?

    thanks for any help :)

    For Internet Connectivity:

    Connect the 2511 into your Linksys (Crossover cable should do the trick for this). Make sure the Ethernet side of the 2511 is in the same subnet as the Linksys LAN side (I use 192.168.1.x for this at home).

    You'll need to make sure the 2511 is configured properly to 'reverse' telnet into the other routers that make up your lab. Also, make sure the 2511 has your linksys LAN ip as the default gateway otherwise Telnet sessions to the 2511 from the outside won't work.

    Finally, you'll need to make sure that you forward port 23 on your Linksys so that it passes Telnet connections to the 2511.

    For Home network connectivity:

    As above since all connections will be going via your Linksys
