FlexFabric 5710 Interface "speed 100" -> the operation is not supported

Hi,

we need to set the speed of a few 1Gbit SFP Ports (Solid Optics JD089B-SO RJ-45) to 100Mbit because of compatibility issues.

[CORESWITCH-Ten-GigabitEthernet1/0/14]speed 100
The operation is not supported.

What does the message mean? The Module does support 10/100/1000 speed

System Info of the switch:
Hardware: Ver.B
Boot ROM: 234
Software: 7.1.070 Release 2612P01

best regards,

Are you sure that JD089B SFP RJ45 Transceiver is able to support 10/100Mbps speeds other than the fixed speed of 1000Mbps (Full Duplex only)?

In any case I really doubt any speed below 1000Mbps (1Gbps) will be permitted on any SFP Transceiver installed into a SFP+ Slot (10Gbps)...

Hi,

on the modules itself is written 10/100/1000Mbit, so i think it must be supported. The Message "the operation is not supported" I receive also on a free SFP-Slot with command "speed 100". Maybe there is another generally configuration parameter to permit speed below 1Gbit?

I doubt that an original HP JD089B SFP Transceiver supports different speeds other than fixed 1000Mbps.

FlexFabric 5710 does not support 100M; only 1GbE and up:

Notation: High 1/10GbE wirespeed ports with 40GbE and 100GbE uplinks

too bad, we have a few (important) 100Mbit hosts, in this case we have to use another switch (uplink) for them

best regards
