The Brocade MLXe 4-port 40 GbE (M) module includes Layer 2, IPv4/IPv6, MPLS and OpenFlow
features, supports 512K IPv4 routes in the Forwarding Information Base (FIB), and requires high
speed switch fabric modules and QSFP+ optics.
Module configuration: System > Module > Add Module
The GUI will add a new module from the selection menu using the following label:
This new selection allows the configuration of the BR-MLX-40GX4-M 4-port 40GbE module.
Module display configuration: System > Module
The GUI will be modified to display a slot that has the configured 4x40GbE card.
Port Display configuration: Port > Ethernet Port Attribute
The GUI will be modified to display the appropriate optic type for 40GigE ports.
NOTE
Optics supported: 40G-QSFP-SR4 for 100M and 40G-QSFP-LR4 for 10KM.
NOTE
Safety requirements are the same as MLX 24x10G.

Forward Error Correction (FEC) mode

Using Forward Error Correction (FEC) mode enabled modules on a Brocade MLXe series chassis will
reduce packet drops due to CRC errors. FEC will automatically be enabled on supported line cards
and fabric links in a Brocade MLXe series chassis.
Forward Error Correction (FEC) mode is applicable for the Brocade MLXe series platforms. It will be
operational on the 16Ke chassis and 32Ke chassis for the following cards:
•
•
•
•
FEC mode is applied on a per link basis. Both sides of the link (TM side and FE side) must be in the
same mode. In a Brocade MLXe series chassis, the following applies:
