hi,

i have all manuals, is not necessary to upload.

--->>> Is Buffer Credit Recovery available all distance level? regardless of L0, LE, LS, LD.

yes, but only beetwen same ASIC's as descripted of Page 426 the PDF ( and not 458 )

--->>> This feature is only supported on long distance E_Ports connected between GoldenEye2 and condor2-based ports.

GoldenEye2 and condor 2 are the New 8GB Switches and DCX ( or the 48K with 8GB Blade )

--->>> If a long distance E_Port is connected to any other type of ASIC, the buffer credit recovery feature is disabled.

Re: What's the Buffer Credit Recovey?

Thanks you !

Finally, If I verify this.

Buffer Credit Recovery mode is available only same between ASICs restricted within Condor2 and GlodenEye2.

For example)

Condor2 to Condor2 -> Buffer Credit Recovery mode is available.

GoldenEye2 to GlodenEye2 -> Buffer Credit Recovery mode is available.

Condor2 to GlodenEye2 -> Buffer Credit Recovery mode isn't available.

Condor2 to Condor -> Buffer Credit Recovery mode isn't available.

Condor2 to GoldenEye -> Buffer Credit Recovery mode isn't available.

Condor to GoldenEye2 -> Buffer Credit Recovery mode isn't available.

GoldenEye to GoldenEye2 -> Buffer Credit Recovery mode isn't available.

Condor to Condor -> Buffer Credit Recovery mode isn't available.

GoldenEye to GlodenEye -> Buffer Credit Recovery mode isn't available.

Is that right ?

Sorry, I'm so confusing to me. ^^;;

You are on the right way

Again, Buffer Credit Recovery is available between all Type "2" ASIC

Condor2 <---> Condor2

GoldenEye2 <---> GlodenEye2

Condor2 <---> GoldenEye2
