I need to purchase some to practice on for my upcoming CCNA-exam. I've found a guy selling some Cisco routers, but he's also saying that he has some Nortel switches he's used for his CCNA and CCNP certification. I don't know the product name of the Nortel switches in question, only that they're 24 and 48 ports.
I know that Nortel is using its own proprietary OS on their switches, and it's sort of similar to IOS, but has anybody here used Nortel for their Cisco certification rather than Cisco equipment?
