AP-175 Signal signal strength

[ Edited ]

I managed to bring up the 5Ghz P2P  and 2.4Ghz. link. 

 

1.Is there any way that I can monitor the RSSI value for the 5Ghz link? Where should I go?

2. What is the default power power for 2.4Ghz link? How to increase the power ( dbm ) to cover more coverage? Where should I go?

 

Beginner here need advise, thanks

Re: AP-175 Signal signal strength

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

Neighbor list
-------------
MAC Portal Channel Age Hops Cost Relation Flags RSSI Rate Tx/Rx A-Req A-Resp A-Fail HT-Details Cluster ID
--- ------ ------- --- ---- ---- -------- ----- ---- ---------- ----- ------ ------ ---------- ----------
00:24:6c:58:5a:e9 00:24:6c:58:14:68 149+ 0 1 7.00 C 3m:36s HL 36 300/300 1 1 0 HT-40MHzsgi-2ss MestTest

Total count: 1, Children: 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

 

(Chuck650) #show ap mesh neighbors ap-name AP175-2

Neighbor list
-------------
MAC Portal Channel Age Hops Cost Relation Flags RSSI Rate Tx/Rx A-Req A-Resp A-Fail HT-Details Cluster ID
--- ------ ------- --- ---- ---- -------- ----- ---- ---------- ----- ------ ------ ---------- ----------
00:24:6c:58:14:68 Yes 149+ 0 0 4.00 P 3m:36s HL 38 300/300 1 1 0 HT-40MHzsgi-2ss MestTest

Total count: 1, Children: 0
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

---------------------------

Name     Mesh Role   Parent   Path Cost  Node Cost  Link Cost  Hop Count  RSSI  Rate Tx/Rx  Last Update  Uplink Age  #Children

----     ---------   ------   ---------  ---------  ---------  ---------  ----  ----------  -----------  ----------  ---------

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.
