Page 30: Vxlan Tunnel Mac-Learning Disable
Usage guidelines When the local-MAC logging feature is enabled, the VXLAN module immediately sends a log message with its local MAC addresses to the information center. When a local MAC address is added or removed, a log message is also sent to the information center to notify the local-MAC change. -
Page 31: Xconnect Vsi
Views System view Predefined user roles network-admin Parameters port-number : Specifies a UDP port number in the range of 1 to 65535. As a best practice, specify a port number in the range of 1024 to 65535 to avoid conflict with well-known ports. Usage guidelines You must configure the same destination UDP port number on all VTEPs in a VXLAN. -
Page 32: Vxlan Ip Gateway Commands
For an Ethernet frame destined for the local site, the VTEP adds 802.1Q VLAN tags to the frame before forwarding the frame. In VLAN access mode, VXLAN packets sent between VXLAN sites do not contain 802.1Q VLAN tags. VXLAN can provide Layer 2 connectivity for different 802.1Q VLANs between sites. You can use different 802.1Q VLANs to provide the same service in different sites. -
Page 33: Bandwidth
Views System view Predefined user roles network-admin Usage guidelines When local proxy ARP is enabled on distributed VXLAN IP gateways, each gateway learns ARP information independently. A gateway does not forward ARP packets destined for its local VSI interfaces to other gateways. For distributed VXLAN IP gateways to have the same ARP entries, you must enable dynamic ARP entry synchronization. -

Page 39: Gateway Subnet
Usage guidelines If a VXLAN uses distributed gateway services, you must assign the same IP address to the VXLAN's VSI interfaces on different VTEPs. To avoid IP address conflicts, you must specify the VSI interface on each VTEP as a distributed gateway. Examples # Specify VSI-interface 100 as a distributed gateway. -

To save resources on VTEPs in an SDN transport network, you can temporarily disable remote ARP learning when the controller and VTEPs are synchronizing entries. After the entry synchronization is completed, use the undo vxlan tunnel arp-learning disable command to enable remote ARP learning.
