different from the runtime setting. For example, if no device is connected to a
port, it can be administratively enabled with a runtime status of DOWN.
If you change other settings on a disabled port, they do
not take effect until you enable the port.
When you disable a port, a linkdown trap is sent to the
management station if you configure an SNMP manager.
|
Duplex
|
Follow these steps to set for duplex: full duplex, half
duplex, or auto:
-
The default setting for Gigabit Ethernet and GigaStack
GBIC ports is auto. These ports automatically match the duplex capability of an
attached device.
-
To set a duplex value other than auto, the speed value
must be other than auto. The duplex value must be auto if the port speed is set
to auto and if the port can run at a speed of 1000 Mbps.
-
GigaStack GBIC stack connections operate in half-duplex
mode.
-
Point-to-point GigaStack GBIC port connections operate in
full-duplex mode.
|
Speed
|
Settings for the 10/100-Mbps and 10/100/1000-Mbps ports:
-
10 (Ports run at a forced speed of 10 Mbps.)
-
100 (Ports run at a forced speed of 100 Mbps.) • 1000
(Ports run at a forced speed of 1000 Mbps.)
-
auto (Ports autonegotiate and advertise all available
speeds.) The default setting for 10/100- and 10/100/1000-Mbps ports is auto.
Ethernet ports can automatically match the transmission speed of an attached
device.
The default setting for 10/100- and 10/100/1000-Mbps ports
is auto. Ethernet ports can automatically match the transmission speed of an
attached device.
