R730 negotiating 100M no matter what I do

[ray_phillips_73]

I've got a brand new batch of about 20 R730 APs. They're all connected to Cisco 2960X PoE+ Switchgear. 

I don't know if I have a power issue or LLDP issue. but all of them running any version of the firmware with or without a controller etc. 

They all are negotiating 100Mb max and I can't even set the speed to 100 through the CMD. 


Haaaaaaalp!!

Hi Ray,

I don't think there is any known issues with R730, which is related to port speed.

You may try below and confirm the results.

1. Power up a R730 using POE injector or power adapter and connect a laptop directly with it. Check if laptop negotiates with 1000/Full
2. Check and make sure LLDP is enabled on both sides (SW and AP). Command for AP is "get lldp".
3. Confirm the firmware version of some of the APs (get version).
4. If possible, do a port mirror on CISCO SW and connect R730 to mirrored port and see what is going on with LLDP.
5. Try connecting AP to a different switch and see the results.

I am also suspecting if this is something with CISCO switch so take a look at SW config as well.

If still can't find the solution, open a support case.

Hi Ray,

As well as Syamantak's excellent advice, also bear in mind the R730 requires high-power PoE (802.3bt) for full performance, as per the data-sheet extract I've attached.


Therefore, when being powered by your Cisco PoE+ (802.3at) switches, certain features will be disabled.

HTH,
Darrel.

Hi Darrel,

Thanks for additional thoughts. However, even with 802.3af power, AP port (PoE port) should still be functional with 10M/100M/1G/5G speeds.

Absolutely! I just wanted the customer to be aware of the of the other AP functionality impacts of low-power mode. The wouldn't be an issue with a Ruckus ICX7150-24P/48P/48PF or multi-gig 7150-48ZP switch, for example. 🙂
