HPE 5710 24SFP+ 6QS+/2QS28 Switch - how to use QSFP28 ports at 100gb

Hello,

I am struggling to find the command to convert the 6 QSFP ports into the 2 QSFP28 ports. There seems to be a mention of this being in a command reference book but have so far been unable to find this in any documentation.

Does anyone know how to use the two QSFP28 ports at the very end of the chassis and enable them to run at 100gb instead of 40gb?

Many thanks,
Rich

Hello Rich5312 ,

I hope the following helps:

Configuration restrictions and guidelines for Ethernet interfaces on the HPE FlexFabric 5710 switch series By default, the six highest-numbered interfaces on this switch series are 40-GE interfaces. Three proximate odd-numbered interfaces (for example, interfaces 49, 51, and 53 or 25, 27, and 29) are in one group and three proximate even-numbered interfaces (for example, interfaces 50, 52, and 54 or 26, 28, and 29) are in one group. To combine three 40-GE interfaces in one group into a 100-GE interface, execute the using hundredgige command on any 40-GE interface in the group. After combination, only the last two 100-GE interfaces are usable (interfaces numbered 53 and 54, or interfaces numbered 29 and 30). To restore a 100-GE interface back to 40-GE interfaces, executing the using fortygige command on the 100-GE interface. If any 40-GE interface in a group is split into four 10-GE interfaces, interfaces in the group cannot be combined into a 100-GE interface. If any 40-GE interface in a group is configured as an IRF physical interface, the using hundredgigecommand is not supported on any interface in the group. If any 100-GE interface is configured as an IRF physical interface, the using fortygige command is not supported on the interface. Interfaces numbered 29 through 36 on the HPE FlexFabric 5710 48SFP+ 6QSFP+ or 2QSFP28 Switch (JL585A) do not support 1000-Mbps SFP modules. Interfaces numbered 29 through 36 on the following switches can be only set to 10000 Mbps or configured to negotiate the 10000 Mbps interface speed with its peer:

HPE FlexFabric 5710 48XGT 6QSFP+ or 2QSFP28 Switch (JL586A).

HPE FlexFabric 5710 24XGT 6QSFP+ or 2QSFP28 Switch (JL689A).

Here is the command reference you can check also the command refence guide under "common ethernet interface commands" in the contents:
