Problem Description

The page opens the high Best Performance, and the vxlan0 mtu is 1500. The data plane (DP) cli checks that the vxlan0 mtu is 1600.


Root Cause

this is normal.
The data plane vxlan0 is used for traffic flow
The result of show interface in cli shall prevail

Solution

No impact, ifconfig sees the kernel network port, kernel vxlan0 does not pass traffic, no effect

Only those born after 670 are like this
Therefore, the vxlan port IP after 670 cannot be pinged directly, you need to use dpping
