Missing tx_retries stats for 5GHz radio

jj_69052 — Mon, 07 Jan 2019 13:07:57 GMT

I'm not sure if I am missing something simple here but I wonder why the "tx_retries" aren't shown for 5 GHz clients on R500 using the command below in the AP CLI.

ruckus(ap-mode)# get station wlanX stats

For any 2.4 GHz wlan it appears just fine and I use it to troubleshoot STA performance. But this value is missing for 5 GHz clients, it only shows "good_tx_frms", "good_rx_frms" and where the "tx_retries" is supposed to be there is nothing.

Is it due to a bug or a driver issue? Maybe the 802.11ac driver isn't supplying this info to the CLI?? (I think the old 7372 showed this value for its 5 GHz radio)

Anybody have a guess?

What version AP/Controller code? Are 5G clients connected? (ie, what does your AP support info show?)

Yes 5G clients are connected, command shows stats for connected clients only.
Currently on Unleashed 200.6.10.1.312 but the same issue exists on Solo 110.0.0.0.675
I only have R500s to test so I don't know if any other AC class access points show the same. As I mentioned the old 7372 did show tx_retries for all clients (not only 2.4 clients like the R500).

Hi JJ,
From an SSH session with your AP, run the "get wlanlist" command to show all WLANx for SSIDs you have configured.You should see some 'wlan0', 'wlan1', and also higher numbers for 5g, 'wlan32', 'wlan33', and so on.
My 'get station wlan32 stats' is showing the client tx_rate, and (tx_per), ack_rssi, and rx_rssi in the paragraph of details.

Yes, notice tx_retries is missing on 5G radio.

Hi JJ,

Still not to worry, you have good connections. Here are two clients, on 2.4g and 5g, each connected at 650mbps, with great signal strength for the 2.4 (44/44) over the 5g (25/27) reported by client RSSIs. I think maybe there were no retries...? Are there any when you have "many" 5g clients connected? OTW, it looks like clean air. 2.4g has more "background noise" per se.

Thanks Michael I know. Yeah it's relatively clean air that's why I haven't been too bothered before but none of the 5g clients ever show tx_retries. Surely this is a bug...Do you see the tx_retries parameter on any of your AC class aps?
