Enterasys Networks 6000 Port Type, Link State, Current Operational Mode, Desired Operational Mode

The Device View

The window displays the following information about the selected Fast Ethernet port:

Port Type

Displays the port’s type: 100Base-TX RJ-45 (for built-in Fast Ethernet ports and the FE-100TX Fast Ethernet port module), 100Base-FX MMF SC Connector (for the FE-100FX Fast Ethernet port module), or Unknown (for a port slot with no module installed).

Link State

Displays the current connection status of the selected port: Link or No Link.

Current Operational Mode

Indicates which of the available operational modes is currently in effect: 10Base-T, 10Base-T Full Duplex, 100Base-TX, 100Base-TX Full Duplex, 100Base-FX, or 100Base-FX Full Duplex. If the port is still initializing, not linked, or if there is no port module installed in the slot, this field will remain blank.

Desired Operational Mode

Displays the operational mode that you have selected for this port, and allows you to change that selection. The following operational modes are available for each port:

100Base-TXAuto-Negotiation, 10Base-T, 10BASE-T Full Duplex, 100Base-TX, and 100Base-TX Full Duplex.

100Base-FX100Base-FX and 100Base-FX Full Duplex

!

CAUTION

If you choose to select a specific mode of operation (rather than auto-negotiation), you should be sure that the link partner supports the same mode. Otherwise, no link will be achieved.

If you select a Full Duplex mode and the link partner supports the same wire speed but not Full Duplex, a link will be achieved, but it will be unstable and will behave erratically.

If you select Auto-Negotiation, the local node will try to match the mode of the link partner, even if the link partner is not set to auto-negotiate, and even if the local node must use a mode which it is not currently advertising.

Note that if Auto-Negotiation is the selected mode, the Current Operational Mode field will indicate which mode was selected by the link partner.

See Setting the Desired Operational Mode, on page 2-42, for more information.

Advertised Abilities

For 100Base-TX ports which have been configured to operate in Auto-Negotiation mode, this field allows you to select which of the operational modes available to the port can be selected by the negotiating link partners.
