26.2.6 Configuring VXLAN PMTU

Configure the thresholds for sending Path MTU Discovery to the Switch and VXLAN Access settings to be applied. The following diagram shows a sample VXLAN PMTU configuration.

Figure 26-12: Sample VXLAN PMTU Configuration

Points to note

Sets 1440byte to the thresholds for sending Path MTU Discovery. Also, set VXLAN Access to which VXLAN PMTU function is applied to 1/0/10.

When a frame exceeding the threshold is received, the port to which VXLAN PMTU function is applied sends a Path MTU Discovery.
