setting will also determine the master and slave relationship between the two connected
physical layers. This relationship is necessary for establishing the timing control between
the two physical layers. The timing control is set on a master
physical layer by a local
source. The slave
setting (
1000M Full_Slave)
uses loop timing, where the timing comes
from a data stream received from the master. If one connection is set for
1000M
Full_Master
, the other side of the connection must be set for
1000M Full_Slave
. Any
other configuration will result in a link down status for both ports.
Flow Control
Displays the flow control scheme used for the various port configurations. Ports
configured for full-duplex use 802.3x flow control, half-duplex ports use backpressure
flow control, and Auto ports use an automatic selection of the two. The default is
Disabled
.
Connection
Here the current connection speed will be displayed.
MDIX
Auto
- Select auto for auto sensing of the optimal type of cabling.
Normal
- Select normal for normal cabling. If set to normal state, the port is in MDIX
mode and can be connected to a PC’s NIC using a straight-through cable or a port (in
the MDIX mode) on another switch through a cross-over cable.
Cross
- Select cross for cross cabling. If set to cross state, the port is in MDI mode, and
can be connected to a port (in the MDIX mode) on another switch through a straight
cable.
Address Learning
Enable or disable MAC address learning for the selected ports. When
Enabled
,
destination and source MAC addresses are automatically listed in the forwarding table.
When address learning is
Disabled
, MAC addresses must be manually entered into the
forwarding table. This is sometimes done for reasons of security or efficiency. See the
section on Forwarding/Filtering for information on entering MAC addresses into the
forwarding table. The default setting is
Enabled
.
Medium Type
If configuring the Combo ports, this defines the type of transport medium to be used.
AutoSpeed
Downgrade
Enable or disable automatically downgrading advertised speed. This function only takes
effect, when
Speed/Duplex
is configured as
Auto
.
Auto Negotiation
Select the auto-negotiation method.
Restart An
- Select to restart auto-negotiation process.
Remote Fault Advertised
- When this option is selected, fault conditions will be remotely
advertised when the next auto-negotiation process takes place. When selecting
Disabled
, remote fault advertisement is disabled. When selecting
Offline
, local devices
that were powered off or removed from the active configuration will be advertised at the
next auto-negotiation. When selecting
Link Fault
, local devices that disconnected due to
link failure will be advertised at the next auto-negotiation. When selecting ANE, the
resolution that precludes operation between local devices and link partners will be
advertised at the next auto-negotiation.
