The following example displays VXLAN statistics for the specified VXLAN tunnel.
DellEMC# show vxlan vxlan-instance 1 statistics remote-vtep-ip 1.1.1.1
Statistics for Remote-vtep-ip : 1.1.1.1
Unicast:
Rx Packets : 0
Rx Bytes : 0
Tx Packets : 0
Tx Bytes : 0
Non-Unicast:

Use the following command to clear the remote VTEP and access port statistics.
DellEMC# clear vxlan vxlan-instance 1 statistics
Disabling MAC Address Learning on Static VXLAN Tunnels
You can configure the system to not learn MAC addresses on static VXLAN tunnels or remote VTEPs.
MAC address learning on static VXLAN tunnels is Enabled by default. To disable MAC address learning on static VXLAN tunnels
or remote VTEPs, follow this procedure:
NOTE:
● This command is only applicable for static VXLAN and does not work for the other modes of VXLAN (controller and
nuage).
● The remote VTEP should already be configured.
● In case of static VXLAN VLT deployments, this configuration should be symmetric across VLT nodes.
● Disable MAC address learning on static VXLAN tunnels.
VXLAN-INSTANCE mode
disable-mac-learning remote-vtep-ip
DellEMC(conf-vxlan-inst-1-static)#disable-mac-learning 24.1.1.0
● Enable MAC address learning on static VXLAN tunnels.
VXLAN-INSTANCE mode
no disable-mac-learning remote-vtep-ip
DellEMC(conf-vxlan-inst-1-static)#no disable-mac-learning 24.1.1.0
Preserving 802.1 p value across VXLAN tunnels
The 802.1p QoS marking preservation is supported over the VXLAN tunnel. The 802.1p priority is carried over from the VXLAN
tunnel to the remote VTEP—VXLAN tunnel endpoint. The packets egress out to the correct queue based on the priority value.
In such a scenario, if there is any congestion in the queue, the system generates a pause. The network port should be a vlan for
priority to be carried by the vxlan outer header.
