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.

Add Module
The GUI will add a new module from the selection menu using the following label:
BR-MLX-40GX4-M 4-port 40GbE Module
This new selection allows the configuration of the BR-MLX-40GX4-M 4-port 40GbE module.

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.
Auto-tuning links
Links brought down by CRC bursts and slow rate CRC receive auto-tuning before fabric link monitoring shuts down those links.
Auto-tuning links for burst CRC
Auto-tuning software will attempt to tune a link that is brought down by hardware due to a CRC burst, and when a slow rate CRC is
encountered, before fabric link monitoring shuts down that link. This enhancement will use existing fabric link monitoring syslog, SFM log
and SNMP trap messages for links shutdown or links powered down.
There are two instances when auto-tuning for a link is triggered:
•
Slow rate CRCs are encountered.
•
Burst CRCs are encountered.
NOTE
The feature for auto-tuning links for burst CRC was introduced in release 5.7.
