Hi Markus,

it is within 60sec all the time (avg 55,1", max 104,6"). As per comparison, a switch stack with 96 ports on same network is polled with 12,4" average and 54,6" max.

Cheers Luca

How does the device performance look? Is polling completed in less than 300s? /Markus

Hi all,

I've a TP-Link T2600-28TS whose ports are continuously detected and then deleted after 2-10 minutes: this happens about every 6 hours, while other switches in the same environment does have normal behaviour. Of course the switch does operate normally all the time.

Tom,

this is the only TP-Link switch on customer site; the others are from another vendor (Extreme Networks), therefore I can't do any comparison.

Best Luca

Every 6 hours is while discovery runs; something on this switch apparently doesn't like what discovery is doing (too high cpu usage -> poller times out and loses sight of ports) ... is it running the same firmware version as the others?
