3.4.2 Configuring Interface Connections
You can use the Port Setup page to enable/disable an interface, set auto-negotiation
and the interface capabilities to advertise, or manually fix the speed, duplex mode,
and flow control.
When configuring interface connections through the web interface or CLI, the
following parameters are displayed or can be configured:
■ Port/s – The port or aggregate link (up links NETP0 to NETP7, and down links
SNP0 to SNP15).
■ Port Description – The label (between 1 and 64 characters) of the interface. The
default for up-link ports is External RJ-45 connector NETn. The default for down-
link ports is Blade Slot n. The default for the management port is External RJ-45
connector NETMGT.
■ Administrative Status – The configured state of the interface. You can disable an
interface due to abnormal behavior (for example, excessive collisions), and then
reenable it after the problem has been resolved. You may also disable an interface
for security reasons.
■ Negotiate Link Capabilities
22
– 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 – 10 Mbit/sec half-duplex operation
■ 10full – 10 Mbit/sec full-duplex operation
■ 100half – 100 Mbit/sec half-duplex operation
■ 100full – 100 Mbit/sec full-duplex operation
■ 1000half – 1000 Mbit/sec half-duplex operation
■ 1000full – 1000 Mbit/sec full-duplex operation
■ symmetric (Gigabit only) – The capability to transmit and receive pause
frames. When disabled, the sender and receiver auto-negotiate for asymmetric
pause frames. (The switch only supports symmetric pause frames.)
■ flowcontrol – Flow control
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 operation and IEEE 802.3x for full-duplex
operation.
