OS for EX Series Ethernet Switches, Release 10.3
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
