Port Configuration
– 119 –
◆ Media Type – Configures the forced transceiver mode for SFP/SFP+ ports, or
forced/preferred port type for RJ-45/SFP combination ports
.
■
None - Forced transceiver mode is not used for SFP/SFP+ ports. (This is the
default setting for RJ-45 ports and SFP/SFP+ ports.)
■
Copper-Forced - Always uses the RJ-45 port.
(
Only applies to combination
RJ-45/SFP ports 23-24 on the ECS4620-28F/28F-DC.)
■
SFP-Forced 1000SFP
- Always uses the SFP/SFP+ port at 1000 Mbps, Full
Duplex.
■
SFP-Forced
100FX - Always uses the SFP port at 100 Mbps, Full Duplex.
(
Only applies to SFP ports on the ECS4620-28F/28F-DC.)
■
SFP-Forced
10GSFP - Always uses the SFP+ port at 10 Gbps, Full Duplex.
■
SFP-Preferred-Auto
- Uses SFP port if both combination types are
functioning and the SFP port has a valid link. The speed is set by
autonegotiation, and the mode is fixed at Full Duplex.
(
Only applies to
combination RJ-45/SFP ports 23-24 on the ECS4620-28F/28F-DC.)
◆ 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.
■
10Gf (10G SFP+ ports only) - Supports 10 Gbps 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 on Gigabit and 10 Gigabit ports;
