24-port 1 Gbps fiber interface module
The 24-port 1 Gbps fiber interface module is available in the following formats:
• BR-MLX-1GFx24-X
• BR-MLX-1GFx24-X-ML
The 24-port 1 Gbps fiber interface modules has 32 Mb of flash memory and provide 24 physical
ports, through which you can connect your router to other network routers. BR-MLX-1GFx24-X-ML
supports up to 512K IPv4 routes in hardware. BR-MLX-1GFx24-X supports up to 1M IPv4 routes in
hardware. The ML version can be upgraded to a X version through a software license. Please
contact Brocade to purchase the license upgrade.
24-port 1 Gbps fiber interface modules support 1 Gbps Copper SFP optics at 10 Mbps, 100Mbps
and 1Gbps speeds.
When you install BR-MLX-1GFx24-X and BR-MLX-1GFx24-X-ML modules, you must upgrade the
software on all interface modules and management modules to the appropriate software release.
For more information on the appropriate software release refer to the Hardware Installation Notes
that shipped with the modules.
When you are replacing older modules with 24x1G modules, you must first delete the software
configuration for the older module. If you do not delete the old configuration, a configuration
mismatch will occur when you install the new module. This mismatch will be displayed in the results
of the show config command.
The SNMP Management Information Base (MIB) uses the Interface Index (ifIndex) to assign a unique
value to each port on a module or slot. The number of indexes that can be assigned per module is
20, 40, or 64, depending on the number of ports on the module. When installing 24-port copper or
fiber interface modules, you must change the ifIndex allocation to 64 before you install the module,
or the module will not operate properly when installed.

modules.
