FIGURE 67 Minimum configuration for 128 Gbps ICLs
1. X6-8 Chassis with two CR32-8 blades 2. X6-4 Chassis with two CR32-4 blades
∙ The maximum number of ICLs between two X6-4 chassis or between a X6-8 and a X6-4 is 16.
The maximum number of ICLs between two X6-8 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.
NOTE
Brocade recommends that you have a maximum of eight ICLs connected to the same neighboring domain, with a maximum of
four ICLs from each core blade.
∙ The ICLs can connect to either core blade in the neighboring chassis. The QSFP ICLs do not need to be cross-connected.
