ICLs for the Brocade DCX 8510 Backbone family

NOTE
You cannot interconnect a Brocade DCX Backbone family chassis to a Brocade DCX 8510 Backbone
family chassis.
Refer to the specific hardware reference manuals for additional information about LED status
meanings and ICL connections, including instructions on how to cable ICLs.
ICLs for the Brocade DCX 8510 Backbone family
Each ICL connects the core blades of two Brocade DCX 8510 chassis and provides up to 64 Gbps
of throughput within a single cable.
You can have up to 32 QSFP ports in a Brocade DCX 8510-8 chassis or 16 QSFP ports in a Brocade
DCX 8510-4 chassis, with up to 2 Tbps ICL bandwidth and support for up to 50 meters on universal
optical cables.
The Brocade DCX 8510-8 has four port groups on the CR16-8 core blade. The Brocade DCX 8510-4
has two port groups on the CR16-4 core blade. Each port group has four QSFP connectors, and
each QSFP connector maps to four user ports. Refer to the hardware reference manuals for details
about the port groups.
Following are ICL configuration guidelines for trunking bandwidth and High Availability:
•
•
•
•
492
ICLs must be installed in groups of two. Each pair of ICLs must be in the same port group.
The recommended minimum number of ICLs between two Brocade DCX 8510 chassis is four.
Additional ICLs should be added in increments of two—one on each core blade.
For High Availability, you should have at least two ICLs from each core blade.
two Brocade DCX 8510-8 chassis connected with full redundancy using four ICL connections.

Minimum configuration for 64 Gbps ICLs
The maximum number of ICLs between two Brocade DCX 8510-4 chassis or between a
Brocade DCX 8510-8 and a Brocade DCX 8510-4 is 16.
The maximum number of ICLs between two Brocade DCX 8510-8 chassis is 32.
Because the FSPF routing logic uses only the first 16 paths to come online, only 16 ICLs are
utilized. With Virtual Fabrics, however, you can define two logical switches on the chassis and
have 16 ICLs in each.
