Previously the customer had two 8530s connected for SRDF/S via two DS8B2 with L2 ports.
Buffer credits were set to 50. The line speed was 1Gb/s and the distance was 100km. The
customer recently migrated from the 8530s to two DMX frames. The long distance configuration
remains the same (same switches and link speed). As a consequence of the migration, block size
changed from 2K to 1K. The same amount of data is being transmitted over the link. Given the
changes in the environment, what actions need to be taken?

A.
No action is required

B.
Increase BB-credits double the amount from the original setting

C.
Decrease RSCN port variable to half of current setting

D.
Additional L2 ports should be installed with no changes to BB_credits
