The MultiSwitch 700 Device View
2-38 Managing the Module
The window displays the following information about the selected Ethernet port:
Port Type
Displays the port’s type: 100Base-TX RJ-45or RJ71 (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), 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.
!
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.
