Enabling auto-negotiation maximum port speed advertisement

Maximum Port speed advertisement is an enhancement to the auto-negotiation feature, a mechanism for accommodating multi-speed network devices by automatically configuring the highest performance mode of inter-operation between two connected devices.

Maximum port speed advertisement enables you to configure an auto-negotiation maximum speed that Gbps copper ports on the RUCKUS device will advertise to the connected device. You can configure a port to advertise a maximum speed of either 100 Mbps or 10 Mbps. When the maximum port speed advertisement feature is configured on a port that is operating at 100 Mbps maximum speed, the port will advertise 10/100 Mbps capability to the connected device. Similarly, if a port is configured at 10 Mbps maximum speed, the port will advertise 10 Mbps capability to the connected device.

The maximum port speed advertisement feature operates independently of logical LAG configurations. Although RUCKUS recommends that you use the same cable types and auto-negotiation configuration on all members of a LAG, you could utilize the auto-negotiation features conducive to your cabling environment. For example, in certain circumstances, you could configure each port in a LAG to have its own auto-negotiation maximum port speed advertisement configuration.
