I need to know if someone has any feedback about mentioned cards in terms of important bugs and/or performance issues. Onthe other hand I would need some description document.

I am thinking in buying these cards but firstly I want to know its behaviour in live networks. Any experience regarding these cards is welcomed.

Thanks in advance!

Howdy:

We have started using these SFPs for our core network and we do not have any real problems. You just need to be careful with the fiber since it's a little more fragile. The only other issue I could see is how much traffic you put on this card since the 4k is a blocking switch. What supervisor are you using?

dtodd,

It is not true to say that 4k is blocking switch as a blanket statement. Some linecards like the the ones discussed here are over-subscribted but 10/100 linecards and 4306 or 4506 or sup uplinks are line-rate. Any IOS supervisor would provide similar rates for the discussed 4448 /4548 modules.

Also the latest WS-C4948 switch is line-rate on all 48 ports ...

Hope the information is helpful..:)

See your point and thanks bsivasub-
