For devices that support the port-speed group feature, the groups are called out in the relevant illustrations with the ports in the group identified.

Some of the devices shown in this section have ports that are grouped together to provide flexibility in configuring Ethernet speeds for the individual members of the group. The default configuration supports the maximum possible Ethernet speed and/or other lower, allowable speeds by the individual members of the group. Care must be taken when inserting optics for lower speed connectivity as further configuration may be required for the port(s) in the group to operate as desired.
