SFP ports problem

hello dears

 

i have a problem with SFP ports.

i have 15  fiber connection from 7250 switches to 6610-24f using cisco 1 Gb SFPs and all connections are work but i want to replace this 6610 with two 7250 but when i replace it no connection work at all ( the ports don't bring up) ,

Note : i dont have any config in any switch of them and i use the same cables and SFPs.

i tried to no shut the ports but no work too.

 

can any one give a solution?

thanks

AFAIK,

 

thirds Verdor SFP like Cisco are not supported on Brocade Ethernet Switches/Platforms

Re: SFP ports problem

The SFP+ units may not work, but regular SFPs are a relatively open standard.

 

It is highly recommended to use Brocade ones for support, but I see no reason Cisco 1G SFPs would not work.

 

I do NOT have a 7250 in my environment, but looking at a 7450-48F, I have to wonder if it is configured for 10 Gigabit or 1 Gigabit/sec

If this is the case, you can probably set the speed to a standard SFP speed...
