Port Configuration
8-4
8
- 1000full - Supports 1 Gbps full-duplex operation
- 10Gfull - Supports 10 Gbps full-duplex operation
- Sym (Gigabit only) - Check this item to transmit and receive pause frames, or
clear it to auto-negotiate the sender and receiver for asymmetric pause frames.
(The current switch chip only supports symmetric pause frames.)
- FC - Supports 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. (Avoid using flow control on a port connected to a hub unless it is
actually required to solve a problem. Otherwise back pressure jamming signals
may degrade overall performance for the segment attached to the hub.)
(Default: Autonegotiation enabled; Advertised capabilities for
1000BASE-T – 10half, 10full, 100half, 100full, 1000full;
1000BASE-SX/LX/LH – 1000full;
10GBASE-SR/LR/ER – 10Gfull)
• Media Type – Shows the forced/preferred port type to use for the combination
ports.
(ES4626F:
Ports
21-24; ES4650F: Ports 45-48)
- Copper-Forced - Always uses the built-in RJ-45 port.
-
SFP-Forced
- Always uses the SFP port (even if module is not installed).
-
SFP-Preferred-Auto
- Uses SFP port if both combination types are functioning
and the SFP port has a valid link.
• Trunk – Indicates if a port is a member of a trunk. To create trunks and select port
members, see “Creating Trunk Groups” on page 8-6.
Note:
Auto-negotiation must be disabled before you can configure or force the interface
to use the Speed/Duplex Mode or Flow Control options.
