Usage guidelines
ARP flood suppression reduces ARP request broadcasts by enabling the VTEP to reply to ARP requests on behalf of VMs.
This feature snoops ARP packets to populate the ARP flood suppression table with local and remote MAC addresses. If an ARP request has a matching entry, the VTEP replies to the request on behalf of the VM. If no match is found, the VTEP floods the request to both local and remote sites.
Examples
# Enable ARP flood suppression for VSI vsi1.
<Sysname> system-view
[Sysname] vsi vsi1
[Sysname-vsi-vsi1] arp suppression enable

Predefined user roles
network-admin
Parameters
all: Specifies broadcast, unknown unicast, and unknown multicast traffic.
broadcast: Specifies broadcast traffic.
unknown-multicast: Specifies unknown multicast traffic.
unknown-unicast: Specifies unknown unicast traffic.
all-direction: Disables flooding traffic received from an AC, VXLAN tunnel interface, or PW to any other ACs and VXLAN tunnel interfaces or PWs of the same VSI. If you do not specify this keyword, the command only disables flooding traffic received from ACs to VXLAN tunnel interfaces or PWs of the VSI.
Usage guidelines
By default, the device floods broadcast, unknown unicast, and unknown multicast frames received from the local site to the following interfaces in the frame's VXLAN:
· All site-facing interfaces except for the incoming interface.
· All VXLAN tunnel interfaces.
When receiving broadcast, unknown unicast, and unknown multicast frames on VXLAN tunnel interfaces, the device floods the frames to all site-facing interfaces in the frames' VXLAN.
To confine a kind of flood traffic, use this command to disable flooding for that kind of flood traffic on the VSI bound to the VXLAN.
You cannot specify the unknown-multicast or unknown-unicast keyword alone. If you specify one of the keywords, you must also specify the other.

Default
VXLAN VSIs do not have static MAC address entries.
Views
System view
Predefined user roles
network-admin
Parameters
mac-address: Specifies a MAC address in H-H-H format. Do not specify a multicast MAC address or an all-zeros MAC address. You can omit the consecutive zeros at the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001.
interface tunnel tunnel-number: Specifies a VXLAN tunnel interface by its tunnel interface number. The tunnel interface must already exist. This option applies to remote MAC addresses.
vsi vsi-name: Specifies a VSI name, a case-sensitive string of 1 to 31 characters.
Usage guidelines
A remote MAC address is the MAC address of a VM in a remote site. Remote MAC entries include manually added MAC entries, dynamically learned MAC entries, and MAC entries advertised through BGP EVPN.
When you add a remote MAC address entry, make sure the VSI's VXLAN has been specified on the VXLAN tunnel.
Do not configure static remote-MAC entries for tunnels that are automatically established by using EVPN.
· EVPN re-establishes tunnels if the transport-facing interface goes down and then comes up. If you have configured static remote-MAC entries, the entries are deleted when the tunnels are re-established.
· EVPN re-establishes tunnels if you perform configuration rollback. If the tunnel IDs change during tunnel re-establishment, configuration rollback fails, and static remote-MAC entries on the tunnels cannot be restored.
The undo mac-address static vsi vsi-name command removes all static MAC address entries for a VSI.
Examples
# Add MAC address 000f-e201-0101 to VSI vsi1. Specify Tunnel-interface 1 as the outgoing interface.
<Sysname> system-view
[Sysname] mac-address static 000f-e201-0101 interface tunnel 1 vsi vsi1

Parameters
tunnel-number: Specifies a tunnel interface number. The value range for this argument is 0 to 10239.The tunnel must be a VXLAN tunnel.
backup-tunnel tunnel-number: Specifies a backup tunnel by its tunnel interface number. The value range for the tunnel-number argument is 0 to 10239.The tunnel must be a VXLAN tunnel.
flooding-proxy: Enables flood proxy on the tunnel for the VTEP to send flood traffic to the flood proxy server. The flood proxy server replicates and forwards flood traffic to remote VTEPs. If you do not specify this keyword, flood proxy is disabled on the tunnel.
all: Specifies all VXLAN tunnels.
Usage guidelines
This command assigns a VXLAN tunnel to a VXLAN to provide Layer 2 connectivity for the VXLAN between two sites. In unicast mode, the system floods unknown unicast, multicast, and broadcast traffic to each tunnel in the VXLAN.
You can assign multiple VXLAN tunnels to a VXLAN, and configure a VXLAN tunnel to trunk multiple VXLANs.
To assign a pair of primary and backup VXLAN tunnels to the VXLAN, specify the backup-tunnel tunnel-number option. When the primary VXLAN tunnel is operating correctly, the backup VXLAN tunnel does not forward traffic. When the primary VXLAN tunnel goes down, traffic is switched to the backup VXLAN tunnel.
On a VSI, you can enable flood proxy on multiple VXLAN tunnels. The first tunnel that is enabled with flood proxy works as the primary proxy tunnel to forward broadcast, multicast, and unknown unicast traffic. Other proxy tunnels are backups that do not forward traffic when the primary proxy tunnel is operating correctly.
To change a flood proxy tunnel for a VXLAN, perform the following tasks:
· Use the undo tunnel command to remove the flood proxy tunnel.
· Use the tunnel command to enable flood proxy on another tunnel and assign the tunnel to the VXLAN.
If you assign VXLAN tunnels to a VXLAN one by one, you cannot remove all the VXLAN tunnels by using the undo tunnel all command.
If you assign all VXLAN tunnels to a VXLAN by using the tunnel all command, you cannot remove the VXLAN tunnels one by one. You can only use the undo tunnel all command to remove all the VXLAN tunnels.
As a best practice, use the tunnel all command only when batch VXLAN tunnel assignment is necessary.
Examples
# Assign VXLAN tunnels 1 and 2 to VXLAN 10000.
<Sysname> system-view
[Sysname] vsi vpna
[Sysname-vsi-vpna] vxlan 10000
[Sysname-vsi-vpna-vxlan-10000] tunnel 1
[Sysname-vsi-vpna-vxlan-10000] tunnel 2

Predefined user roles
network-admin
Parameters
destination-mac mac-address: Specifies a destination MAC address in H-H-H format for BFD control packets. The MAC address can be a remote VTEP address or a multicast address. You can omit the consecutive zeros at the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001.
Usage guidelines
Enable BFD on both ends of a VXLAN tunnel for quick link connectivity detection. The VTEPs periodically send BFD single-hop control packets to each other through the VXLAN tunnel. A VTEP sets the tunnel state to Defect if it has not received control packets from the remote end for 5 seconds. In this situation, the tunnel interface state is still Up. The tunnel state will change from Defect to Up if the VTEP can receive BFD control packets again.
For BFD sessions to come up, you must reserve a VXLAN by using the reserved vxlan command.
Examples
# Enable BFD on VXLAN tunnel interface Tunnel 9, and specify 1-1-1 as the destination MAC address for BFD control packets.
<Sysname> system-view
[Sysname] interface tunnel 9 mode vxlan
[Sysname-Tunnel9] tunnel bfd enable destination-mac 1-1-1

Parameters
vsi-name: Specifies a VSI name, a case-sensitive string of 1 to 31 characters.
Usage guidelines
A VSI acts as a virtual switch to provide Layer 2 switching services for a VXLAN on a VTEP. A VSI has all functions of a physical Ethernet switch, including source MAC address learning, MAC address aging, and flooding.
A VSI can provide services only for one VXLAN.
Examples
# Create VSI vxlan10 and enter VSI view.
<Sysname> system-view
[Sysname] vsi vxlan10
[Sysname-vsi-vxlan10]

Parameters
vxlan-id: Specifies a VXLAN ID in the range of 0 to 16777215.
Usage guidelines
You can create only one VXLAN for a VSI. The VXLAN ID for each VSI must be unique.
Examples
# Create VXLAN 10000 for VSI vpna and enter VXLAN view.
<Sysname> system-view
[Sysname] vsi vpna
[Sysname-vsi-vpna] vxlan 10000

vxlan local-mac report
Use vxlan local-mac report to enable local-MAC logging.
Use undo vxlan local-mac report to disable local-MAC logging.
Syntax
vxlan local-mac report
undo vxlan local-mac report
Default
Local-MAC logging is disabled.
Views
System view
Predefined user roles
network-admin
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.
With the information center, you can set log message filtering and output rules, including output destinations. For more information about configuring the information center, see System Management Configuration Guide.
Examples
# Enable local-MAC logging.
<Sysname> system-view
[Sysname] vxlan local-mac report
vxlan tunnel mac-learning disable
Use vxlan tunnel mac-learning disable to disable remote-MAC address learning.
Use undo vxlan tunnel mac-learning disable to enable remote-MAC address learning.
Syntax

vxlan udp-port
Use vxlan udp-port to set the destination UDP port number for VXLAN packets.
Use undo vxlan udp-port to restore the default.
Syntax
vxlan udp-port port-number
undo vxlan udp-port
Default
The destination UDP port number is 4789 for VXLAN packets.

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.
Examples
# Set the destination UDP port number to 6666 for VXLAN packets.
<Sysname> system-view
[Sysname] vxlan udp-port 6666
xconnect vsi
Use xconnect vsi to map an AC to a VSI.
Use undo xconnect vsi to restore the default.
Syntax
xconnect vsi vsi-name [ access-mode { ethernet | vlan } ]
undo xconnect vsi
Default
An AC is not mapped to any VSI.

Parameters
vsi-name: Specifies the VSI name, a case-sensitive string of 1 to 31 characters.
access-mode: Specifies an access mode. The default access mode is VLAN.
ethernet: Specifies the Ethernet access mode.
vlan: Specifies the VLAN access mode.
Usage guidelines
For traffic that matches an AC of a VSI, the system uses the VSI's MAC address table to make a forwarding decision.
The access mode determines how a VTEP processes the 802.1Q VLAN tags in the inner Ethernet frames assigned to the VSI.
· VLAN access mode—Ethernet frames received from or sent to the local site must contain 802.1Q VLAN tags.
¡ For an Ethernet frame received from the local site, the VTEP removes all its 802.1Q VLAN tags before forwarding the frame.
¡ 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.
· Ethernet access mode—The VTEP does not process the 802.1Q VLAN tags of Ethernet frames received from or sent to the local site.
¡ For an Ethernet frame received from the local site, the VTEP forwards the frame with the 802.1Q VLAN tags intact.
¡ For an Ethernet frame destined for the local site, the VTEP forwards the frame without adding 802.1Q VLAN tags.
In Ethernet access mode, VXLAN packets sent between VXLAN sites contain 802.1Q VLAN tags. VXLAN cannot provide Layer 2 connectivity for different 802.1Q VLANs between sites. You must use the same 802.1Q VLAN to provide the same service between sites.
