C1000 PoE problems

[md-abuzalath1]

Hello, I have an issue with my Cisco Catalyst 1000 switch. I have a Hikvision camera, and when I connect it to any other switch, it draws 2.5 watts. However, when I connect it to the Cisco Catalyst 1000, it draws 15 watts. I have updated the switch to the latest firmware version. Are there any solutions to this?

The initial allocation for Class 0, Class 3, and Class 4 powered devices is 15.4 W. When a device starts up and uses CDP or LLDP to send a request for more than 15.4 W, it can be allocated up to a maximum of 30 W.

check 

show power inline consumption 

you can use the below command on the interface level -

power inline consumption 5000

check the configuration guide and make necessary changes on the port where possible to use lower Power :

this is work but it shows this message is this normal : consumption/allocation' command may cause damage to the switch and void
your warranty. Take precaution not to oversubscribe the power supply.
It is recommended to enable power policing if the switch supports it.
Refer to documentation.

Personally, this may be information since you are changing from default to different, maybe a caution notice, I guess; I have never seen myself before, nor have Deviec gone lower than 15. X w

Hi,

Please make sure LLDP is enabled for the power management/negotiation (it is disabled by default with Cat1000), both globally ("lldp run") and under the interface where the camera is connected ("lldp transmit", "lldp receive"), also please disable CDP under the camera interface ("no cdp enable").

Best regards,
