Table
FC_MR-4 Card Distance Extension Port Settings
Description
(Display only.) The card port number.
If checked, allows additional distance by providing a
GFP-T based flow control scheme. It enables the node to be
a part of a Storage Area Network (SAN) with
long-distance, remote nodes. If left unchecked, the
remaining options are not available for editing. If Distance
Extension is enabled, set the connected Fibre Channel
switches to Interop or Open Fabric mode, depending on the
Fibre Channel switch. By default, the FC_MR card will
interoperate with the Cisco MDS storage products.
If checked, enables the node to detect the transmit credits
from a remote node. Credits are used for link flow control
and for Extended Link Protocol (ELP) login frames
between Fibre Channel/fiber connectivity (FC/FICON)
Switch E ports.
Sets the number of credits if an ELP login frame setting is
missing or if the ELP login frame cannot be detected.
Credits Available is editable only if Auto Detect Credits is
unchecked.
Longer distances between connected devices need
Note
more credits to compensate for the latency
introduced by the long-distance link. The value
should never be greater than the number of credits
supported by the FC/FICON port.
