10 Mbps speed negotiation on Ethernet port

Before Cisco IOS XE Release 17.16.1, the IW9167EH WGB did not support 10 Mbps speed on its ethernet ports. However, some clients still used devices with 10 Mbps Ethernet ports. To ensure compatibility with these devices, support for 10 Mbps speed was introduced.

Starting with Cisco IOS XE Release 17.16.1, the IW9167EH WGB supports 10 Mbps speed negotiation on the wired 0 port. This document describes how to enable and disable 10 Mbps speed negotiation on the WGB wired 0 port.

The WGB wired 0 port connects wired devices to the WGB, bridging wired and wireless network segments.

Speed negotiation

Speed negotiation, or auto-negotiation, is a process in which two connected Ethernet devices automatically select optimal common transmission parameters, such as speed and duplex mode, to optimize communication

Speed and duplex are auto-negotiated based on the capabilities of the locally connected endpoint.

Note

Disable the 10 Mbps feature when you connect devices that support 100 Mbps and 1 Gbps.

Benefits

This feature allows you to connect your 10 Mbps Ethernet devices to the IW9167EH WGB APs without replacing them.

Enable a 10 Mbps speed port on Cisco IW9167EH WGB

This procedure describes how to enable the 10 Mbps speed on the Ethernet port. You can run the show commands as needed, and you do not have to use a specific sequence.

Procedure

Use the configure wired wired-port-number speed port-speed enable command to enable 10 Mbps speed capability on the wired 0 port.

Example:

Device#configure wired 0 speed 10 enable

(Optional) Use the show running-config command to verify 10 Mbps speed port status on the wired 0 port.

Device#show running-config
