RFS4000 adopts AP7562 and unadopts it instantly

[Roman_Yusupov]

Hello guys!
Can you help me with this question?
Im running RFS4000 and adopt 1 AP7562 as Root directly connected to RFS. When I try to adopt another AP via Mesh network, I see it adopted for 1 second and then it unadopts back. It happens continiously. AP doesn't even upload config from RFS. First AP works as usual.

Thank you!

At this point, I would hope that the mesh connection has formed between the non-root and root nodes.

Thank you Chris!
All changes implemented! Waiting for further instructions!

Roman,

I forgot to mention one particular item originally. If this is in fact a VMM deployment, you want to configure the PATH method to "mobile-snr-leaf" (default value is "uniform". This alternate path setting adjust the characteristics of the mesh formations using different metrics and also prevents a non-root from going through another non-root.

mobile-snr-leaf

• SnR based routing
• Turns on mobility bit
• Turns on leaf bit (leaf AP’s cannot hop through each other)
• Uses SnR in auto channel selection

The change is here in the main AP Profile (Applies to any non-root APs)

meshpoint-device ShougangMine
no root
monitor critical-resource action no-root
monitor primary-port-link action no-root
path-method uniform <-- Change this to "mobile-snr-leaf"
hysteresis period 60
exclude wired-peer mint-level-1
acs priority-meshpoint 5GHz ShougangMine
acs priority-meshpoint 2.4GHz ShougangMine


Now regarding the results:
The radios are seeing each other. The SNR is a little weak, but they should still be able to form a link.
I think the problem has to do with an unsupported mode on these .11ac model APs. Was supported on previous generation .11n APs.

Change this setting on each radio...on all APs.

interface radio1
channel 13
rate-selection opportunistic <-- Change to "standard"

interface radio2
channel 136
rate-selection opportunistic <-- Change to "standard"

Even if this still doesn't resolve the issue, these changes needed to be made anyway.
