back pressure is used for half-duplex operation and IEEE 802.3-2005 (formally
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 100BASE-TX –
10half, 10full, 100half, 100full; 1000BASE-T – 10half, 10full, 100full, 1000full;
1000BASE-SX/LX/LH – 1000full)
• Media Type – Configures the forced/preferred port type to use for the combination
ports
. ( Ports 27-28)
- 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. (This is the default.)
• Trunk – Indicates if a port is a member of a trunk. To create trunks and select port
members, see “Creating Trunk Groups” on page 3-133.
Web – Click Port, Port Configuration or Trunk Configuration. Modify the required
interface settings, and click Apply.
