Switch PoE Problem

[pingmaster]

Hi guys. 

I have an Enterasys C5-series_06.81.08.0005 model switch. Third-party outdoor APs are connected to this switch. The AP can draw a maximum of 12W of power and can't operate at full capacity.
I have multiple C5 switches, and the power is the same on all outdoor APs, max 12W.
How can I resolve this issue?

(su)->show port inlinepower ge.1.6
Port Type Admin Oper Priority Class Power(W) Capability 
------- ----- ------ ----------------- -------- ----- -------- ---------- 
ge.1.6 auto Delivering Power Critical 4 11.80 802.3at

NOTE: The command “set lldp port tx-tlv all” was recommended. I ran this command, but the problem remains the same.

To fix this, you need to manually override the power limit on the specific ports to force the switch to provide the full PoE+ budget. Run the following command (adjusting for your specific port):

set port inlinepower ge.1.6 power 30000

This forces the port to allocate 30W (30,000mW) regardless of what the AP negotiates. If that doesn't resolve it, verify your total system power budget with show inlinepower to ensure the switch isn't oversubscribed.

Enterasys C5 switches rely heavily on LLDP power negotiation for PoE+.
If the AP does not correctly advertise power requirements via LLDP, the switch plays it safe and limits power to Class 3 (≈12.95W).
