Switches for CCIE R&S labs

Answered Question
Jan 15th, 2008


I want to buy 2x 3550 and 2x 3560 switches. I am a bit confused about the 3550s. On eBay I found many relatively cheap 3550-SMIs which have the EMI image installed. My question with regards to the CCIE labs, would I have any disadvantage buying these SMI switches with EMI image installed? Is that even allowed?

Or should I stay away from those, and get the real EMI switches instead?

Thanks in advance!


I have this problem too.

yes, that's what it means. Previous switches were tied to SMI or EMI in the hardware, not the 3550/3560.

the 3550's and 3560's are software upgradeable to EMI. The EMI images are referred to as IP Services and SMI images are referred to as IP Base.

In otherwords, purchasing a 3550-SMI with an EMI image installed, is just fine technically. I won't comment on whether or not Cisco is OK with it.

I just acquired a 3550-48-SMI today actually and upgraded it to the EMI (IP services) image w/ crypto.

For the 3560, I believe the R/S lab uses the Adv. Ip Services image, which looks to me like it is the IP Services image, plus IPv6.

Thank you both for your comments!

Does this mean that the 3550-SMI w/ EMI image is equal in terms of software functionality to the 3550-EMI switch?
