Azrulzack,
You can easily monitor the RSSI on either side of a mesh link. There are a couple of ways to do it.
I use the CLI command "show ap mesh neighbors ap-name <NAME>". I do this on each side of the link. This gives me the most comprehensive information. Here is a sample output, first from the mesh portal "AP175-1" and then from the point "AP175-2"
(Chuck650) #show ap mesh neighbors ap-name AP175-1

Relation: P = Parent; C = Child; N = Neighbor; B = Blacklisted-neighbor
Flags: R = Recovery-mode; S = Sub-threshold link; D = Reselection backoff; F = Auth-failure; H = High Throughput; L = Legacy allowed;
a = SAE Accepted; b = SAE Blacklisted-neighbour; e = SAE Enabled; u = portal-unreachable; o = opensystem

You can also use the command “show ap mesh topology” which will give you a summary of all nodes in the mesh. However, as you can see from the output below it does not currently display the RSSI on the portal side of the link.
(Chuck650) #show ap mesh topology
Mesh Cluster Name: MestTest
---------------------------

---- --------- ------ --------- --------- --------- --------- ---- ---------- ----------- ---------- ---------
AP175-1 Portal (N) - 3 1 0 0 0 - 2m:31s 3m:35s 1
AP175-2 Point (N) AP175-1 4 0 0 1 37 300/300 2m:35s 2m:50s 0
Total APs :2
(R): Recovery AP. (N): 11N Enabled. For Portals 'Uplink Age' equals uptime.
As for your question about radio power, that is in two places. Most people run ARM, so you would change the Min-TX-EIRP or Max-TX-EIRP in the appropriate “rf arm-profile”.
If ARM is not running, then you can hardwire a specific output power value in the “dot11g radio profile” .
Hope that helps.
