# trying to switch a port OFF:
root@switch-realtek-838x-zyxel-gs1900-8hp:~# ubus call poe manage "{\"port\":\"lan1\","enable":\"false\"}"
Command failed: Parsing message data failed

i am sure my syntax is wrong,
can sombody please give a working example?

[mrnuke]

ubus call poe manage ' { "port" : "lan1", "enable" : true }'
ubus call poe manage ' { "port" : "lan1", "enable" : false }'

"Searching" tells me what I need to know: your PoE device hasn't responded to the low-level protocol to request power in the first place. The port is nevertheless enabled.

FWIW Sometimes this comes out of a port mapping issue, I believe we've tested the GS1900-8HP though.

thanks a lot @mrnuke - my mistake was really,
that \"enable\" was not correctly escaped,
so both are working:

ubus call poe manage '{ "port" : "lan1", "enable" : false }'
or
ubus call poe manage "{ \"port\" : \"lan1\", \"enable\" : true }"

for the record, after writing a full configfile,
i can switch off and on all ports using above method - bravo!

root@switch-realtek-838x-zyxel-gs1900-8hp:~# cat /etc/config/poe
config global
    option budget   '170'

config port
    option enable   '1'
    option id   '1'
    option name 'lan1'
    option poe_plus '1'
    option priority '2'

config port
    option enable   '1'
    option id   '2'
    option name 'lan2'
    option poe_plus '1'
    option priority '2'

config port
    option enable   '1'
    option id   '3'
    option name 'lan3'
    option poe_plus '1'
    option priority '2'

config port
    option enable   '1'
    option id   '4'
    option name 'lan4'

a full info dump including all 8 ports looks like this.
spot the ports 2, 4 and 8, which are enabled AND active.
