Decoupling of PoE and datalink operations on regular PoE ports
Decouples PoE and datalink operations on regular PoE ports.
While PoE and datalink operations are functionally independent of each other, some datalink
operations affect the operational behavior of PoE ports. When the optional decouple-datalink
keyword is configured using the inline power command, the datalink operational behavior on a PoE
port does not affect the power state of the powered device (PD) that is connecting to the port. You can
also configure the power limits and power-management priority. The inline power command is
available in interface configuration mode for most PoE ports and the inline power ethernet command is
available in global configuration mode for LAG ports.
Perform the following steps to enable inline power and decouple the behavior of the Power over
Ethernet (PoE) and the datalink operations for regular PoE ports. This task provides a method of
overriding the current default behavior of datalink operations that affect the operation of PoE ports.
When the optional decouple-datalink keyword is used when enabling inline power using the inline
power command, the datalink operational behavior on a PoE port will not affect the power state of the
powered device (PD) that is connecting to the port.
NOTE
To enable inline power and decouple PoE and datalink operations on PoE LAG ports, see the
“Decoupling of PoE and datalink operations on PoE LAG ports” task.
Configure this task on the Brocade PSE for any PoE ports that require the decoupling of PoE
operations and datalink operations. Any Layer 2 features can then be configured and deployed on
these PoE ports.
1. Enables interface configuration for a PoE port.
Device(config)# interface ethernet 1/1/1
Interface configuration mode is entered for Ethernet 1/1/1 port.
2. Configure inline power on the Ethernet 1/1/1 port with the power-by-class option.
Device(config-if-e1000-1/1/1)# inline power decouple-datalink power-by-class 3
Configures inline power on the PoE port, Ethernet 1/1/1, with power-by-class option 3 and
decouples the datalink operations and the PoE operations for this port.
3. Enables interface configuration for Ethernet 1/1/2 port.
Device(config-if-e1000-1/1/1)# interface ethernet 1/1/2
Interface configuration mode is entered for Ethernet 1/1/2.
4. Configure inline power on Ethernet 1/1/2 port with the default option.
Device(config-if-e1000-1/1/2)# inline power decouple-datalink
Configures inline power on Ethernet 1/1/2 port and decouples the datalink operations and the PoE
operations for this port.
5. Enables interface configuration for Ethernet 1/1/3 port.
Device(config-if-e1000-1/1/2)# interface ethernet 1/1/3
Interface configuration mode is entered for Ethernet 1/1/3.
6. Configure inline power on Ethernet 1/1/3 port with the power management option.
Device(config-if-e1000-1/1/3)# inline power decouple-datalink priority 2
Configures inline power on port 1/1/3 with power management option 2 and decouples the datalink
operations and the PoE operations for this port.
