Recently i bought CSS326-24G-2S+ and of course update that on the latest version SwOS (2.7). I configured only identity and ip address and connected all users into the switch. All 24G ports were used. On monday, near half of working day, switch was stopping forwarding and didn't reply on the web-interface and ping. But all ports were active. After reboot it was working normally, but today it were happing again.
