8.9.1 Performance Monitoring
8.9.1 Performance Monitoring
GFP-T performance monitoring (GFP-T PM) is available via remote monitoring (RMON), and trunk PM
is managed according to Telcordia GR-253-CORE and ITU G.783/826. Client PM is achieved through
RMON for FC and GE.
8.9.2 Distance Extension
A buffer-to-buffer credit management scheme provides FC flow control. With this feature enabled, a port
indicates the number of frames that can be sent to it (its buffer credit), before the sender is required to
stop transmitting and wait for the receipt of a “ready” indication The MXP_MR_2.5G and
MXPP_MR_2.5 cards support FC credit-based flow control with a buffer-to-buffer credit extension of
up to 1600 km (994.2 miles) for 1G FC and up to 800 km (497.1 miles) for 2G FC. The feature can be
enabled or disabled.
8.9.3 Slot Compatibility
You can install MXP_MR_2.5G and MXPP_MR_2.5G cards in Slots 1 to 6 and 12 to 17. The
TCC2/TCC2P card is the only other card required to be used with these muxponder cards. Cross-connect
cards do not affect the operation of the muxponder cards.
8.9.4 Interoperability with Cisco MDS Switches
You can provision a string (port name) for each fiber channel/FICON interface on the MXP_MR_2.5G
and MXPP_MR_2.5G cards, which allows the MDS Fabric Manager to create a link association between
that SAN port and a SAN port on a Cisco MDS 9000 switch.
8.9.5 Client and Trunk Ports
The MXP_MR_2.5G card features a 1550-nm laser for the trunk/line port and a 1310-nm or 850-nm laser
(depending on the SFP) for the client ports. The card contains eight 12.5 degree downward tilt SFP
modules for the client interfaces. For optical termination, each SFP uses two LC connectors, which are
labeled TX and RX on the faceplate. The trunk port is a dual-LC connector with a 45 degree downward
angle.

modules for the client interfaces. For optical termination, each SFP uses two LC connectors, which are
labeled TX and RX on the faceplate. There are two trunk port connectors (one for working and one for
protect). Each is a dual-LC connector with a 45-degree downward angle.
8.9.6 Faceplates
Figure 8-21 shows the MXP_MR_2.5G and MXPP_MR_2.5G faceplates.
