ICL licensing
21
On the Brocade DCX 8510-8, this license enables QSFP ports 0–7; QSFP ports 8–15 are disabled.
(QSFP ports 0–7 correspond to core blade port numbers 0–31, and QSFP ports 8–15 correspond
to core blade port numbers 32–63, as observed in switchShow output.)
This license allows you to purchase half the bandwidth of the Brocade DCX 8510-8 ICL ports
initially and upgrade with an additional ICL license to use the full ICL bandwidth later. This license is
also useful for environments with ICL connections between a Brocade DCX 8510-8 and a DCX
8510-4, as the latter supports half the bandwidth of the DCX 8510-8 on each ICL port.
This license is available on the Brocade DCX 8510-8 and DCX 8510-4 platforms only.
ICL 2nd POD license
The ICL 2nd POD license provides dedicated high-bandwidth links between two Brocade DCX
8510-8 platforms without consuming valuable front-end ports. Each Brocade DCX 8510-8 platform
must have the ICL 2nd POD license installed to enable the full number of ICL connections possible.
This license is available for the Brocade DCX 8510-8 only.
ICL 8-link license
The ICL 8-link license activates half of the ICL bandwidth for each ICL port on the Brocade DCX
platform by enabling only half of the ICL links available. This allows you to purchase half the
bandwidth of the Brocade DCX ICL ports initially and upgrade with an additional ICL license to use
the full ICL bandwidth later. This license is also useful for environments with ICL connections
between a Brocade DCX and a DCX-4S, as the latter cannot support more than eight links on an ICL
port.
This license is available on the Brocade DCX-4S and DCX platforms only.
ICL 16-link license
The ICL 16-link license provides dedicated high-bandwidth links between two Brocade DCX chassis,
without consuming valuable front-end ports. Each Brocade DCX chassis must have the ICL 16-link
license installed in order to enable the full number of ICL connections possible (16 links in the case
of a DCX chassis).
This license is available for the Brocade DCX only.
Enterprise ICL license
The Enterprise ICL (EICL) license allows you to connect more than four Brocade DCX 8510
Backbones through ICLs. This license is available on the Brocade DCX 8510-8 and DCX 8510-4
platforms only.
The EICL license is required in addition to the ICL POD license.
The following requirements apply:
• Connection of four or fewer DCX 8510 Backbones with ICLs does not require the EICL license.
However, if you add additional ICL-connected chassis, then all ICL-connected chassis require
the EICL license.
• With the EICL license installed, a maximum of 10 chassis are allowed to be connected together
via ICLs.
