Per-Chain signals from AP Side?

Products ePMP

Hi.  How to we see the per-chain RX Signals on the AP side of things for each connection?  We are seeing a percentage of Force300-25 with mismatched signals on their receive side, but that info doesn't seem to be displayed in a table anywhere other than in eAlign.

So, on the AP side, where can we see the AP's per-chain receive signal strength in a table somewhere?

BUMP CAMBIUM - How do I see the per-chain signals on the AP side of things for each connection?

It doesn't appear that this is possible.  Even the CLI only shows you an aggregate RSSI.

OK, thank you.  That's shockingly absurd. 

@Cambium - you need to add this. How we we supposed to know if there's an uplink chain mismatch?

In TDD PTP mode eAlign Tool is available on AP and can be used to check UL RSSI per-chain.

Thank you.

Thank you for the reply. Yes, Correct, in TDD PTP mode it has that feature. That needs to be available in TDD PtMP mode too.

Every association needs to display it's per-chain RSSI both directions. If the reason that isn't displayed now, is because there isn't enough real estate... then just have the Uplink Signal as a link which bubbles up a window on mouseover - such as you do now with the little (i) infomation icons.  We need to have some way to see if these SM's have the 10 dB chain mismatch both ways, or just one way - or what....  and without trying to just infer that from the MCS rates.  ("Hmm... this SM is a -61 uplink, but it keeps dropping to SS 5 so guess maybe - or maybe not - it's broken chains?")

We will consider adding that information on UI.

In case of broken chains on SM most likely you will see RSSI chains imbalance both in DL and UL.

In case of the issue on AP side, you will see RSSI mismatch on every SM.

Thank you.
