Cisco SDM..what type of router?

Thanks for access.. Site looks great. Anyway, I'm a fourth semester
Netacad student, and I hit a brick wall with doing SDM labs. Although I do attend an official class, I do alot of labs at home on my 2950's and 2650's.. Last weekend, I found out SDM doesnt support 2650's.. --They need to be of the XM variety. What does an XM have that my regular 2650 doesn't have?

Second question: I just want to get a XM type that has expansion slots so I can plug in a couple of WIC-1T's (must be db-60) what do you all recommend?

thanks all

nnbnbTo break it down to it’s finest point.. Not much.. the XM line has the better processor and will support SDRAM while the non-XM only support slower DRAM memory.

As far as your question about what type of router would be best.. I can’t give you that.. The way I look at questions like that is more like… How deep is your pockets? Look around on ebay, there is some good deals out there, I’ve just posted a link to a article about buying fake cisco gear.. While you do shop for your new router, have cisco’s search page open and do some research..

Regarding XM/SDM. The only thing I can think of at the moment that could prevent SDM from working on none-XM routers is the amount of Flash and RAM available. XM (eXtended Memory) basically has more flash/RAM.

For a new router, you probably know that most of the 2600 series routers generally have 1 NM slot and 2 WIC slots. This can support upto a total of 4 WICs. If you could hunt a good price for the 2621XM or 2651XM, it would be great because these have 2 built in FastEthernet ports.

yeah, I ended up buying a 2650XM.. according to cisco.com, sdm supports this router. bought it for $125 and a couple of WIC-1T's for $10 each

thanks
