ICLs for the Brocade DCX Backbone family
22
To establish ICL trunking between platforms in the Brocade DCX 8510 Backbone family, the QSFP
cables must be in the same trunk group, as illustrated in Figure 73.
Refer to the specific hardware reference manuals for information about port numbering and
connecting the ICL cables.
ICLs for the Brocade DCX Backbone family
The Brocade DCX has two ICL connectors at ports ICL0 and ICL1 on each core blade, each
aggregating a set of 16 ports. Thus, each core blade provides 32 ICL ports and there are 64 ICL
ports available for the entire Brocade DCX chassis. All the ICL connector ports must be connected
to the same two Brocade DCX or DCX-4S chassis.
The Brocade DCX-4S has two ICL connector ports at ICL0 and ICL1, each aggregating a set of 8
ports. Thus, each core blade provides 16 ICL ports and there are 32 ICL ports available for the
entire Brocade DCX-4S chassis. All the ICL connector ports must be connected to the same two
Brocade DCX or DCX-4S chassis.
Only the following cross-ICL group connections are allowed, as illustrated in Figure 74:
• ICL0 ports on the first chassis connect to ICL1 ports on the second chassis.
• ICL1 ports on the first chassis connect to ICL0 ports on the second chassis.
FIGURE 74 DCX-4S allowed ICL connections
The following ICL connections are not allowed:
• ICL0 ports to ICL0 ports
• ICL1 ports to ICL1 ports
