Decoupling of PoE and datalink operations on PoE LAG ports
Decouples PoE and datalink operations on PoE ports.
Perform the following steps to decouple the behavior of the Power over Ethernet (PoE) and the datalink
operations for PoE Link Aggregation Group (LAG) 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 ethernet
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.
Configure this task on the Brocade PSE for any PoE ports that require the decoupling of inline power
and datalink operations. Any layer 2 features can then be configured and deployed on these PoE ports.
To avoid the disruption of inline power after the LAG ports are powered up, configure the following steps
in the specified order.
1. Configure inline power on the primary port with the power-by-class option.
Device(config)# inline power ethernet 1/1/1 decouple-datalink power-by-class 3
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.
2. Configure inline power on a secondary port with the default option.
Device(config)# inline power ethernet 1/1/2 decouple-datalink
Configures inline power on port 1/1/2 and decouples the datalink operations and the inline power for
this port.
3. Configure inline power on a secondary port with the power management option.
Device(config)# inline power ethernet 1/1/3 decouple-datalink priority 2
Configures inline power on port 1/1/3 with power management option 2 and decouples the datalink
operations and the inline power for this port.
4. Configure inline power on a secondary port, specifying the actual power value.
Device(config)# inline power ethernet 1/1/4 decouple-datalink power-limit 12000
Configures inline power on the port 1/1/4, specifying an actual power value of12000 mW and
decouples the datalink operations and the inline power for this port.
5. Configure a LAG.
Device(config)# lag "mylag" static id 5
Configures a static LAG named mylag with an ID of 5.
6. Configure ports into the LAG membership.
Device(config-lag-mylag)# ports ethernet 1/1/1 to 1/1/4
Configures the four ports, 1/1/1, 1/1/2, 1/1/3, and 1/1/4, into the LAG membership.
7. Configure a primary port for the LAG.
Device(config-lag-mylag)# primary-port 1/1/1
Configures port 1/1/1 as the primary port.
8. Deploy the LAG.
Device(config-lag-mylag)# deploy
LAG mylag deployed successfully!
Deploys the mylag LAG.
