To avoid the disruption of inline power after the LAG ports are powered up, perform the following
configuration steps in order.
1. Configure inline power on the primary port with the power-by-class option.
The following example configures inline power on the primary port,1/1/1, with power-by-class option
3 and decouples the datalink operations and the inline power for this port.
Device(config)# inline power ethernet 1/1/1 decouple-datalink power-by-class 3
2. Configure inline power on a secondary port with the default option.
The following example configures inline power on port 1/1/2 and decouples the datalink operations
and the inline power for this port.
Device(config)# inline power ethernet 1/1/2 decouple-datalink
3. Configure inline power on a secondary port with the power-management priority option.
The following example configures inline power on port 1/1/3 with power-management priority 2 and
decouples the datalink operations and the inline power for this port.
Device(config)# inline power ethernet 1/1/3 decouple-datalink priority 2
4. Configure inline power on a secondary port, specifying the actual power value.
The following example configures inline power on the port 1/1/4, specifying an actual power value of
12000 mWatts, and decouples the datalink operations and the inline power for this port.
Device(config)# inline power ethernet 1/1/4 decouple-datalink power-limit 12000
5. Configure a LAG.
The following example configures a static LAG named mylag with an ID of 5.
Device(config)# lag "mylag" static id 5
6. Configure ports into the LAG membership.
The following example configures the four ports, 1/1/1, 1/1/2, 1/1/3, and 1/1/4, into the LAG
membership.
Device(config-lag-mylag)# ports ethernet 1/1/1 to 1/1/4
7. Configure a primary port for the LAG.
The following example configures port 1/1/1 as the primary port.
Device(config-lag-mylag)# primary-port 1/1/1
8. Deploy the LAG.
The following example deploys the mylag LAG.
Device(config-lag-mylag)# deploy
LAG mylag deployed successfully!
Decoupling of PoE and datalink operations on regular PoE ports
Use this procedure to decouple 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
