9800 WLC Controller association Latency

[Mikey Boy]

Hi, we have 9800 WLC images hosted in AWS. Across multiple sites we see the "controller association latency" reported as into multiple minutes. This does not appear to be causing a problem, but I cannot find documented anywhere what this figure actually relates to.

It does not appear to be related to Link latency as these values seem ok.

You can view it from Configuration -> Select an AP and it shows just under the DHCP information.

Thanks

Hi

  This value tells how long the AP took to join the WLC . I just had a look in one WLC (on premise) and it shows 0 d, 00 h 01 m 31. s. If this value is too high and AP drops from WLC, you may have longer interval with no SSID available. 

You can also check "AP Link Latency " just to check link latency from the AP perspective.
