These switches are an optional item in the blade chassis, apparently they sell quite a bit of them. I have 4, personally, and will probably have more when we need another blade center.
All that being said, they run a dual mode CLI. Unfortunately, to access all of the features, using the IOS-like version that supports a lot of Cisco-style commands doesn't work, instead, you have to run it in Alteon OS mode. These products are OEM Nortel (formerly Alteon products) and use the old Alteon OS CLI which uses / commands instead of things like sh run.
If I wanted to see everything piece of information on the switch, I'd do something like /info/sys/general or /info/l2/port or /info/l3/if to see Layer 3 interfaces.. It's close enough to Alteon that my other (free as in beer) configuration management system handles them nicely using the Alteon template.
How can I get these devices included in the next release, or a template created that will work for them?
