and IEEE802.3x 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 is permanently disabled on ports 1-16, and
enabled on ports 17-19; Advertised capabilities for
RJ-45: 100BASE-TX (Port 19) – 10half, 10full, 100half, 100full;
1000BASE-T – 10half, 10full, 100half, 100full, 1000full;
SFP: 1000BASE-SX/LX/LH – 1000full when a module is installed)
Media Type – Shows the forced/preferred port type to use for the
combination ports.
(
Ports
17-18)
-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 9-8.
