2960 - Switch Stack Member Configuration Question

Quintin.Mayo
Level 2
Level 2

Hi,

 

We want to add some new AP's to our environment and want to you ports on a specific switch stack member (5).  I reviewed some documentation and found to connect to the specific member I can use the "Session x" command. But the documentation inform only the show and debug commands are available. We need to provide POE to port 1-7 on the stack member, can anyone confirm how to accomplish this?  My thoughts are below for connecting to the stack member and configuring the ports to receive power.

 

Test# session 5

Test-5# config t

config t

interface range gi1/0/1-7

power inline auto

end

Hi,

You don't need to access the member switch to configure the port. You just log in to the master and configure the ports for switch #5.

5/0/1-5/0/x

Hello,

You can configure it directly from your master member.

sw(config): interface range gi 5/0/1 - 7
sw(config-if): power inline auto

Thanks in advance.

Adding to other post, you do not required to go in to session, since the switch already part of your stack member, you can directly configure from master switch conrol plane.

 

here is some reference for the power

 
Maximum Power Allocation (Cutoff Power) on a PoE Port

When power policing is enabled, the switch determines one of the these values as the cutoff power on the PoE port in this order:

  1. Manually when you set the user-defined power level that the switch budgets for the port by using the power inline consumption default wattage global or interface configuration command

  2. Manually when you set the user-defined power level that limits the power allowed on the port by using the power inline auto max max-wattage or the power inline static max max-wattage interface configuration command

  3. Automatically when the switch sets the power usage of the device by using CDP power negotiation or by the IEEE classification and LLDP power negotiation.

Use the first or second method in the previous list to manually configure the cutoff-power value by entering the power inline consumption default wattage or the power inline [auto | static max] max-wattage command.

If you do not manually configure the cutoff-power value, the switch automatically determines it by using CDP power negotiation or the device IEEE classification and LLDP power negotiation. If CDP or LLDP are not enabled, the default value of 30 W is applied. However without CDP or LLDP, the switch does not allow devices to consume more than 15.4 W of power because values from 15400 to 30000 mW are only allocated based on CDP or LLDP requests. If a powered device consumes more than 15.4 W without CDP or LLDP negotiation, the device might be in violation of the maximum current (Imax) limitation and might experience an Icut fault for drawing more current than the maximum. The port remains in the fault state for a time before attempting to power on again. If the port continuously draws more than 15.4 W, the cycle repeats.
