FIGURE 12 64 Gbps ICL topology
To connect two Brocade DCX 8510 switches redundantly, at least 4 ICL connections are required.
To achieve full redundancy, each core blade in a chassis must be connected to each of the two core
blades in the destination chassis, as shown in Figure 13.
FIGURE 13 Minimum configuration for 64 Gbps ICLs
If you want to add more QSFP cables, one QSFP cable from each blade must be connected to the
same blade of its neighbor. There must be a symmetrical number of QSFPs per blade. The
maximum number allowed between two chassis is 4 QSFPs per blade, within the 4 port QSFP trunk
boundary, which equals a total of 8 QSFPs per chassis.
If the QSFP ICLs and ISLs (including E_Ports and VE_Ports) are connected to the same neighboring
switch in the same logical switch, the default switch or a Non-VF switch are not supported. This is a
topology restriction with new 16 Gpbs ICL and any ISLs that are E_Ports or VE_Ports.
