Randomly Link UP & Link Down on ports are noticed on random ports on M4300-52G-PoE+ ProSAFE 48-port

Hi Team,

 

We use switch (M4300-52G-PoE+ ProSAFE 48-port 1G PoE+ and 2-port 10GBASE-T and 2-port 10G SFP+) as Layer 2 switch configured with Static IP. 

 

Wifi Access Points are connected to this Switch for our internal lab testing. Certain times, randomly we notice that there is network loss for few seconds. While i check the logs on the switch i see Link up and down traps are generated on the ports.

 

Switch is running with Factory defaults with Spanning Tree Admin Mode disabled. Did several reboots and factory reset on the switch but nothing solved the problem.

Also ensure that, there is no loop with in the switch. Need expertise help in order to resolve this. Some ideas or leads to resolve this would be greatly appreciated as this is causing the network unstable and unreliable.

 

below is the logs and switch firmware details for reference. Experts, please feel free to let me know in case if you need more information from my end. 

 

Firmware Version12.0.4.8
Boot VersionB1.0.0.11
CPLD Version0x1
Internal AC-1Operational
Internal AC-2Not present
EPS/RPSNot present
