What IOS does cat3550-24 use?

[chongzhang]

Hello,

I want to use cat3550 for its QoS feature.

Does the cat3550-24 use Rel. 12.1(6)EA1?

On the http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/1216ea1/ol162601.htm#82532, it only mentions cat3550-12t/g.

Another q: what's the best solution if I want to use

cat3550-24 and to support 100Base-FX?

Thanks very much!

Cat3550-24 is not FCS yet so the above IOS is for

the following mentioned hardware.

Once the new switch is officially available, you should see release notes and software which supports that the new switch. I believe there is a new software for that switch but I am not 100 % sure since there is no document yet.

Since 3550-24 has 24-10/100 TX ports and 2 GBIC port, you may need to use Transceiver to get 100BaseTx to 100BaseFx.
