Juniper JUNOS OS 10.3 - SOFTWARE, Manual

If you are connecting a desktop phone or wireless access point or a security camera to
a Power over Ethernet (PoE) port, you can configure some parameters for the PoE
interface. The PoE interfaces are enabled by default. For detailed information on PoE
settings, see “Configuring PoE (CLI Procedure)” on page 3315.
If you are connecting a device to other switches and to routers on the LAN, you need to
assign the interface to a logical port and configure the logical port as a trunk port. See
“Port Role Configuration with the J-Web Interface (with CLI References)” on page 1149 for
more information about port configuration.
To configure a Gigabit Ethernet interface or 10-Gigabit Ethernet interface for trunk port
mode:

Configuring the Link Settings
EX Series switches include a factory default configuration that enables interfaces with
the following link settings:
• All Gigabit Ethernet interfaces are set to auto-negotiation .
• The speed for Gigabit Ethernet interfaces is set to auto , allowing the interface to operate
at 10m, 100m or 1g. The link operates at the highest possible speed, depending on the
capabilities of the remote end.
•
The flow control for Gigabit Ethernet interfaces and 10-Gigabit Ethernet interfaces is
set to
enabled .
• The link mode is set to auto , allowing the interface to operate as either full duplex or
half duplex. The link operates as full duplex unless this mode is not supported at the
remote end.
•
The 10-Gigabit Ethernet interfaces default to
no auto-negotiation
. The default speed
is 10g and the default link mode is full duplex.
