Port Configuration
– 103
SFP-Forced-1000SFP - Always uses the SFP port (even if a module is not
installed), and configured for a 1000BASE SFP transceiver. The speed is set
by autonegotiation, and the mode is fixed at Full Duplex
SFP-Forced-100FX - Always uses the SFP port (even if a module is not
installed), and configured for a 100BASE-FX transceiver. The speed is set by
autonegotiation, and the mode is fixed at Full Duplex.
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 the
combination ports.) The speed is set by autonegotiation, and the mode is
fixed at Full Duplex.
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.
10h
- Supports 10 Mbps half-duplex operation.
10f
- Supports 10 Mbps full-duplex operation.
100h
- Supports 100 Mbps half-duplex operation.
100f
- Supports 100 Mbps full-duplex operation
1000f
- Supports 1000 Mbps full-duplex operation.
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 operation and IEEE
802.3-2005 (formally IEEE 802.3x) for full-duplex operation.
Default: Autonegotiation enabled;
Advertised capabilities for
100BASE-FX (SFP) – 100full;
1000BASE-T – 10half, 10full, 100half, 100full, 1000full;
1000BASE-SX/LX/ZX (SFP) – 1000full
Speed/Duplex
– Allows you to manually set the port speed and duplex mode.
(i.e., with auto-negotiation disabled)
Flow Control
– Allows automatic or manual selection of flow control.
(Default: Enabled)
