Hello Weda,

Here is the reference about how EXOS MTU works.

Hope it will help you.

Best regards,

You can change the MTU on our switches (default is 1500). Which includes the MAC, IP, TCP, vlan headers.

The below wiki page has a example calculation from MSS to MTU. Hope this helps

I would think the mss value would be set on the application. Our switch doesn't look into the payload to check the MMS(maximum segment size). We look at the MTU.

I want to adjust mss to 1390 in order to have a symmetry with 2 WAN connections.
but I can set MTU as 1500. Below that, it is not allowed.
