Enterasys Networks Matrix E7, 6000 manual Remote Capabilities, Setting the Desired Operational Mode

The Device View

During Auto-Negotiation, each of the link partners will advertise all selected modes in descending bandwidth order: 100Base-TX Full Duplex, 100Base-TX, 10Base-T Full Duplex, and 10Base-T. Of the selected abilities, the highest mode mutually available will automatically be used. If there is no mode mutually advertised, no link will be achieved.

If you have selected a specific operational mode for your 100Base-TX port, the Advertised Abilities do not apply; the selected Advertised Abilities also do not restrict the local node’s ability to set up a link with a partner who is not currently Auto-Negotiating.

NOTE

Auto-Negotiation is not currently supported for 100Base-FX ports.

Remote Capabilities

When the local node is set to Auto-Negotiation, this field will display the advertised abilities of the remote link — even if the remote link is not currently set to auto-negotiate. Possible values for this field are:

•100Base-TX Full Duplex

•100Base-TX

•10Base-T Full Duplex

•10Base-T

•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 be grayed out, even if the link partner is set to Auto-Negotiation and is advertising abilities.

NOTE

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.
