Dac cable is 4×10 40G (ONE SINGLE DAC IS CONNECTED TO 4 UBIQUITI)
Similarly with 2 netgear
For some reason it goes down and still interface is communicating
Deu to which my controller say device offline
Netgear port configuration
#interface 0/1
#port-mode 4×10G
#Switchport mode trunk

Hi asifshaikh04 ,
I responded to your other thread https://community.netgear.com/t5/Managed-Switches/MLag-and-LACP-configuration-on-M4500-using-CLI/td-p/2353628/jump-to/first-unread-message
If you are using portmode 4x10G here, we may have interop issue with the breakout DAC cable; or with the way the third-party switches handle it on the other end.
Please upgrade the M4500 CSM4532 switch with latest software:
https://www.netgear.com/support/product/m4500-32c#download
Please use the release notes for the method updating the firmware.With the latest software, you will have the AV User Interface, and it will be easier to produce the Tech Support file (Diagnostics/Support Diagnostics). In the TS file, there are all the show fiber command that will help understand the problem on the port / DAC.
Also, with the 4x10G port mode, there are four new ports in the M4500 switch. You need to configure LAG on these new ports accordingly (not sure if you are using 2x10G to one third-party switch, and 2x10G to another third-party switch).
The portmode 4x10G command is creating 4 new ports. These new ports need to be configured, added to LAG, as any other port. The port numbering is different for them. The tech-support file will help us understand where you are and what to do.
Please the use the Software Administration Manual page 43 to see the port numbering of the 4x10G in your case. I believe you need to configure LAG on these new ports. https://www.netgear.com/support/product/m4500-32c#docs
