2-46 Managing the Module
FE-100FX Fast Ethernet port module), 1000Base-SX/LX/CX (for the VHSIM-G6 Gigabit
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.
Remote Auto Signal
Indicates whether the operating mode at the remote end of the link is set to Auto
Negotiate.
Auto Negotiate Config
Indicates whether Auto Negotiate signalling is in progress or has completed. Possible
values for this field are: configuring, complete, disabled, parallel detect failed, or other.
Auto Negotiate Mode
Use this field to enable or disable Auto Negotiate for the port. If Auto Negotiate is
disabled, the port will use the speed, duplex mode, and flow control settings specified in
the Operational Mode fields. Note that 100-BaseFX ports do not support Auto
Negotiation; they must use the control settings specified in the Operational Mode fields.
Operational Mode Fields
If the port is not set to Auto Negotiate then the settings in the Operational Mode fields are
used.
The Current Operational Mode settings indicate which of the available operational
modes is currently in effect. If Auto Negotiate is the selected mode, the Current
Operational Mode fields will indicate which mode was selected by the link partner.
The Desired Operational Mode settings display the operational mode that is currently
selected for this port, and allows you to change the selection.
The following operational modes can be specified:
Speed
This field specifies a port speed of 10MB, 100MB, or 1000MB.
!
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.
For example, if you select 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.
