[c-nsp] Will UDLD work with converters ?

[Church, Charles]

Definitely avoid aggressive mode with converters, unless you've got errdisable recovery timers enabled.  Otherwise if you reload one side, the other side will stop receiving UDLD but it's link is still up (from the converter), so it'll errdisable the port.

According to the doc if I am using a TX port the DEFAULT is UDLD  
DISABLED, so I have to enable it and also it states that I need to run  
in AGGRESSIVE MODE when using TX.


I think I read that correct!
