Model : T2700G-28TQ

Hardware Version :

Firmware Version : 2.0.1 Build 20170608 Rel.61525(s)

ISP :

We have a stack built using 2 T2700G-28TQ as an edge switches with uplinks using 2 pairs of SFP+.

The remaining 4 SFP+ ports are connected to 2 set of external switches in a layer 2 LAG active configurations, of which 2 are connected to another T2700G-28TQ and the other 2 are connected to a stack using H3C 5800E switches.

The switch has been running for a week or so and there is level 4 warning saying that " MEMORY RISING THRESHOLD: Total Memory Utilization is 81%".

The memory utilization can go up as high as 91% and then when there is a connection of LAG between the T2700G-28TQ and the H3C stack is manually disconnected, the T2700G-28TQ will go haywire and one of them will reboot. All connections on the T2700-28TQ are not working and the only resolution is to reboot both T2700G-28TQ while the H3C and other connections are untouched.


For your advice please.
