•Link Partner does not support auto negotiation — auto negotiation is either not supported by or is not currently selected on the remote port.
•Unknown — the link partner’s capabilities could not be determined.
When the local node is not set to Auto-Negotiation, this field will remain blank, even if the link partner is set to Auto-Negotiation and is advertising abilities.
If both link partners are set to Auto-Negotiation, but there is no mutually-advertised operational mode, no link will be achieved, and both nodes may display the message “Link Partner does not support Auto-Negotiation.” To resolve this situation, be sure both link partners advertise all their abilities, or be sure they advertise at least one mutually-available mode.
Setting the Desired Operational Mode
For any 100Base-TX port, you can specifically choose any one of the four available operational modes, or you can select Auto-Negotiation mode, which allows the port to negotiate with its link partner to find the highest mutually available bandwidth. If you select Auto Negotiation mode, you must also choose which of the port’s bandwidth capabilities you wish to advertise to the link partner.
If you select Auto-Negotiation at both ends of a link, be sure at least one
TIP mutually-advertised operational mode is available.
For a 100Base-FX port, the selection process is somewhat simpler; Auto Negotiation for these ports is not supported at this time, so you need only choose between 100Base-FX standard mode and 100Base-FX Full Duplex. However, you must still be sure that both link partners are set to the same operational mode, or the link will be unstable.
To set your desired operational mode:
1.Click in the Desired Operational Mode field to display the menu of available options; drag down to select the operational mode you wish to set.
For 100Base-TX ports, the available options are: 10Base-T— 10 Mbps connection, Standard Mode 10Base-T Full Duplex — 10 Mbps connection, Duplex Mode 100Base-TX— 100 Mbps connection, Standard Mode 100Base-TX Full Duplex — 100 Mbps connection, Duplex Mode
Auto Negotiation — the operational mode will be dynamically set based on the modes selected in the Advertised Abilities field (where both link partners are auto-negotiating) and the speeds and modes supported by the attached device
