SummaryThis article describes what needs to be done to negotiate 802.3at power between R710 AP and POE+switchesQuestionWhat to do to negotiate 802.3at power between R710 AP and POE+switchesCustomer EnvironmentR710s either standalone or controller managedRoot CauseLLDP and LLDP power over MDI should be enabled on the POE+ switch in order for 802.3at power to be negotiated between the R710 and POE+ switch.Troubleshooting StepsUse rkscli command "get power-mode" to check input power consumption status.
rkscli: get power-mode
PoE Configured Mode : Auto
Power Consumption Status : 802.3at PoE+
OK
"PoE Configured Mode" should be "Auto" not "AF".
When PoE+ switch with LLDP power via MDI support is connected, the " Power Consumption Status" will be "802.3at PoE+".
Here are options for " Power Consumption Status".
{ "Unknown" },
{ "DC" },
{ "802.3at PoE+" },
{ "PoE Injector" },
{ "802.3af PoE" },ResolutionThere are 3 requirements for the R710s to negotiate 802.3at power between itself and the POE+ switch,
two of them are on the POE+ switches and one on the Ruckus R710-:
1. LLDP must be enabled on the POE+ switches.
2. LLDP Power via MDI must be enabled on the POE+ switches.
The command to enable LLDP and LLDP power via MDI will vary depending on the make of the switch.
3. LLDP and LLDP POE setting must be enabled on the R710s. R710s received with 100.2.0.0.336 have both LLDP and LLDP POE setting ENABLED by default.
However, R710s received with firmware prior to 100.2.0.0.336 DON'T have LLDP and LLDP POE setting enabled by default.
These settings WON'T be enabled even after upgrading to 100.2.0.0.336 or RuckOS 3.1.1.x.x or later.
So if R710s received with firmware prior to 100.2.0.0.336, then later upgraded to 100.2.0.0.336 or 3.1.1.x.x, still need to have LLDP and LLDP POE enabled.
This can be done via CLI on the R710.
rkscli: set lldp enable
rkscli: set lldp poe enable
You can do a get lldp to make sure the ap took the two config changes.
rkscli: get lldp
LLDP state: Enabled
LLDP interval: 30
LLDP holdtime: 120
LLDP mgmt: Enabled
LLDP poe: Enabled
LLDP power: 25000
LLDP interface:
LLDP on eth0 : Enabled
LLDP on eth1 : Enabled
OK
PS: Negotiation may take up to 2 minutes after system is up.
