You are configuring a 10 km long distance ISL between a Brocade DCX 8510 and a Brocade
5300 with no additional license. Which two configurations are needed? (Choose two.)

A.
Configure the ISL ports at both ends for LE.
B.
Configure the ISL ports at both ends for LD.
C.
Configure the fill word to ARB on the ISL port of the 5300.
D.
Configure the fill word to ARB on the ISL ports on both ends of the ISL.
LD mode required a license.
The 5300 has a Condor 2 ASIC thus needs ARB fill word for ISL. Condor 3 ASICs don’t need fill word modifications.
