poe+

[juan_romero]

HELLO, I´M HAVING A PROBLEM WITH X460 SWITCH RUNNING XOS 15.6.3.1, THINK IT IS NOT GIVING ME THE RIGHT POE, I´M USING ONE PORT TO CONNECT A 3COM SWITCH (3CNJ2000) THAT HAVE TWO POE PORTS AND IN BOTH PORTS I´M OBTAINING DATA BUT NO POWER TO FEED TWO AVAYA PHONES. HOW CAN I KNOW EXTREME IS GIVING ME THE CORRECT POWER TO FEED THE 3COM SWITCH? I HAVE TRIED SEVERAL INLINE-POWER CONFIGURATIONS WITH NO SUCCESS.

Hi Juan, if you're still having trouble with this, I'd recommend that you open a case with GTAC.

According to 3CNJ2000 documentation:

If power is supplied to the uplink port by 802.3at or by the external power supply, then ports 1 and 2 may act as PoE PSE (Power Source Equipment) and may also provide power to other devices plugged into those ports.

If power is supplied by 802.3af, then port 1 and 2 will not be able to supply PoE power.

Based on the outputs they were negotiated using 802.3af.

Yes I tried with lldp and with legacy but still not working

[Henrique]

Hi Juan, did you try the command "enable inline-power legacy"?

Another option would be trying to provide power based on LLDP MED as already mentioned before:

"configure lldp ports 3:18 advertise vendor-specific med capabilities"

"configure lldp ports 3:18 advertise vendor-specific dot3 power-via-mdi with-classification"

I don't see any command to force PoE+ in a port or even a minimum power.
