Port Configuration
– 126 –
◆ The 1000BASE-T standard does not support forced mode. Auto-
negotiation should always be used to establish a connection over any
1000BASE-T port or trunk. If not used, the success of the link process
cannot be guaranteed when connecting to other types of switches.
PARAMETERS
These parameters are displayed in the web interface:
◆ Port – Port identifier.
◆ Type – Indicates the port type. (1000Base-T, 1000Base SFP)
◆ Name – Allows you to label an interface. (Range: 1-64 characters)
◆ Admin – Allows you to manually disable an interface. You can disable
an interface due to abnormal behavior (e.g., excessive collisions), and
then re-enable it after the problem has been resolved. You may also
disable an interface for security reasons.
◆ Media Type – Configures the forced/preferred port type to use for the
combination ports
.
■
Copper-Forced - Always uses the built-in RJ-45 port.
■
SFP-Forced
- Always uses the SFP port, even if a module is not
installed. (This is the default for Ports 3-24.)
■
SFP-Preferred-Auto
- Uses SFP port if both combination types are
functioning and the SFP port has a valid link. (This is the default for
Ports 1-2.)
◆ Autonegotiation (Port Capabilities) – Allows auto-negotiation to be
enabled/disabled. When auto-negotiation is enabled, you need to
specify the capabilities to be advertised. When auto-negotiation is
disabled, you can force the settings for speed, mode, and flow
control.The following capabilities are supported.
■
10half - Supports 10 Mbps half-duplex operation
■
10full - Supports 10 Mbps full-duplex operation
■
100half - Supports 100 Mbps half-duplex operation
■
100full - Supports 100 Mbps full-duplex operation
■
1000full (Gigabit ports only) - Supports 1000 Mbps full-duplex
operation
■
Sym - Check this item to transmit and receive pause frames.
■
FC - Flow control can eliminate frame loss by “blocking” traffic from
end stations or segments connected directly to the switch when its
buffers fill. When enabled, back pressure is used for half-duplex
