I have two Brocade 5100 switches (OEM IBM). A week ago, when they worked under FabOS v6.4.3h they ware as 8G switches. After upgrade to v7.4.2c thay become only 4G. My all ports are N4Gbps and I could not chanage to N8Gbps. My SFP are:
Transceiver: 540c404000000000 2,4,8_Gbps M5,M6 sw Short_dist
When I try to change port speed to 8G an error appears:
Mod_Inv Speed Mismatch / Incompatible SFP FAULTY
Solved! Go to Solution.

do you have 8Gb License ?
From License guide:
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. 14 Fabric OS Software Licensing Guide 53-1003110-01 2 Slot-based licensing 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 port on the switch, or the switchDisable and switchEnable commands on the switch, to enable 8 Gbps features. • When you remove the 8G license, the ports that are online and already running at 8 Gbps are not disturbed until the port goes offline or the switch is rebooted. The switch ports return to their pre-licensed state maximum speed of 4 Gbps.

It was a long way to upgrade from v6.
My full path was:
v6.4.3h ---> v7.0.0d ---> v7.1.0c ---> v7.2.0b (maps convert) ---> v7.3.0c ---> v7.4.0b ---> v7.4.2c
Fabric Watch license
Extended Fabric license
Performance Monitor license
First Ports on Demand license - additional 8 port upgrade license
Second Ports on Demand license - additional 8 port upgrade license
At v6 and at v7.4 are the same (as above)
Full Fabric is also called the Fabric license (visible in licenseShow
output) as I read at FOS_LicenseGuide_v740.pdf
I have no idea what was happend.

could you please paste full ouput of SFP show ?
I only thnking if the SFPs are brocade branded or rebrand by IBM......
Please share portcfgshow and portlogdumpport for one of affected port

Thank you for your time and help.
All ports are affected. I have tested 3 types of sfp's: - native Brocade (IBM OEM), lets say Brocade compatible and HP-A. HP was only taken from new HPE switch for tests on my IBM OEM Brocade 5100 switch - type 2498-B40.
Native Brocade sfp and compatible works fine at this switch when it was running FabOS v6.4.3

Yes, HBA at host is 8.
I have tested sfp witch loopback plug button.
All sfps works at different switch (not the same about I talk) but the same model IBM 2498-B40 but under fabos 6.4.3h so thay are hardware healthy, I think.

sorry i doesn't menitoned id, but we need porlogdump when you change speed to 8Gb so there will be stamp what happened and why the spped not negotiate to 8Gb.
As i remmember for 8Gb platform you can only use Brocade branded SFPs.
And pelase share output of sfpshow 15

Thank you one more. Bad luck - there is no my last entry. I repeat then again.
I have tested the problematic sfp's in another switch Brocade 5300 running FabOS 7.4.2d and switch recognize it properly - as N8.
Then back to this one with sfp problems - 5100 v7.4.2c - the same: Speed Mismatch / Incompatible SFP. All output from my tests at attachement. What I have noticed: if there is no module at port it shows N8. See attch. If I plugin sfp port change switch to N4. This may evicence that sfp is not comatible but it works at 5300. Any idea? I have exhausted ideas.Do I have to accept this situation?
Please take a look at attachement.

Port 15 does not use an SFP or is disabled...

No, I did not change anything on the host side - neither hba's firmwares nor device drives. This switch was allocated to different fabric (detached, cleared from any configuration, upgraded from 6.4.3 to 7.4 and attached to fabric with two other switches 4g to migrate hosts from 4 to 8g).
