SM Session "Stuck"

MW_WISP · October 19, 2016, 7:18am

Sometimes some SM become unreachable via management IP or via AP (using proxy), I have this problem on various APs.

I'm using Management VLAN and the SM has NAT enable, when the SM "stuck" the NAT still works but it randomly drops sessions or some IP addresses on the same network are unreachable..

I never had this problem with older FSK radios

This is a dump of the SM after a "Drop Session" performed on the AP

Hi NW_WISP,

We will investigate this but meanwhile upgrade to 14.2.1 we have many bug fixes there.

14.1.1 is relly old.
