Brocade Fabric OS Software Licensing Guide (Supporting Fabric OS v7.3.0) - Manual (Page 24)

The EICL license is required in addition to the ICL POD license.
The following requirements apply:
• Connection of three or fewer DCX 8510 Backbones with ICLs does not require the EICL license.
However, EICL license is required on a Brocade DCX 8510 chassis when that chassis is
connected to four or more DCX 8510 Backbones via ICLs.
• With the EICL license installed, a maximum of 10 chassis are allowed to be connected together
via ICLs.
• When Virtual Fabrics are used, the limit on the number of chassis connected together via ICLs
depends only on the physical chassis and not on the logical switches.
• If the maximum number of ICL-connected chassis exceeds the allowed limit with or without the
EICL license, additional links may either be disabled or segmented. The disabling or segmenting
reason code depends on whether the EICL license is installed.
• If ICL links to a chassis become segmented for non-EICL-related reasons, these links are part of
the fabric, and the chassis containing these segmented links is included in the maximum chassis
count. If the maximum chassis count (with or without the EICL license) is reached with these
segmented links, then any additional links will become segmented. Therefore, to add additional
links, you first must disable the links that became segmented due to non-EICL reasons. This
should reduce the maximum chassis count and allow the new links to join.
Example: switchShow output if no Enterprise ICL license is installed
A message such as the following is displayed if a required EICL license is not installed:
440 8 24 ------ id 16G Online FC E-Port segmented,
10:00:00:05:33:0d:52:00 (No EICL License)(Trunk master)
441 8 25 ------ id 16G Online FC E-Port segmented,
10:00:00:05:33:0d:52:00 (No EICL License)(Trunk master)
Example: switchShow output if maximum number of chassis is reached
A message such as the following is displayed if the maximum number of supported chassis is
reached:
384 5 0 ------ id 16G Online FC E-Port segmented,
10:00:00:05:1e:39:bf:9a (EICL License Limited)(Trunk master)
385 5 1 ------ id 16G Online FC E-Port segmented,
10:00:00:05:1e:39:bf:9a (EICL License Limited)(Trunk master)
8G licensing
ATTENTION
The 8G license is installed by default and you should not remove it. Port operation may become
disrupted, and ports may be prevented from operating at 8 Gbps when the license is removed.
The 8G license applies to the Brocade 300, 5100, 5300, and VA-40FC switches and the 8 Gbps
embedded switches; this license does not apply to the Brocade 6505, 6510, or 6520.
The following list describes the basic rules of using, adding, or removing 8G licenses:
• Without an 8G license, even if there is an 8 Gbps SFP plugged into a port in an applicable
platform, the port would be enabled to run at a maximum speed of 4 Gbps.
• To obtain an 8G license, only the license ID from the switch is required. When you add the 8G
license, you must enter either the portDisable and portEnable commands on each individual
8G licensing
