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 the VSI vsi1.
<Sysname> system-view
[Sysname] vsi vsi1
[Sysname-vsi-vsi1] arp suppression enable

encapsulation
Use encapsulation to configure a frame match criterion for an Ethernet service instance.
Use undo encapsulation to remove a frame match criterion from an Ethernet service instance.
Syntax
encapsulation s-vid vlan-id [ only-tagged ]
encapsulation s-vid vlan-id c-vid vlan-id
encapsulation { default | tagged | untagged }
undo encapsulation
Default
An Ethernet service instance does not contain a frame match criterion.
Views
Ethernet service instance view
Predefined user roles
network-admin
mdc-admin
Parameters
s-vid vlan-id: Matches frames that are tagged with the specified outer 802.1Q VLAN ID. The value range is 1 to 4094. If the outer 802.1Q VLAN is not the PVID, the matching result does not differ, whether or not you specify the only-tagged keyword. If the outer 802.1Q VLAN is the PVID, the matching result depends on whether or not the only-tagged keyword is specified.
only-tagged: Matches only PVID-tagged frames. To match both untagged frames and PVID-tagged frames, do not specify this keyword.
s-vid vlan-id c-vid vlan-id: Matches frames that are tagged with the specified outer and inner 802.1Q VLAN IDs. The vlan-id argument specifies an 802.1Q VLAN ID in the range of 1 to 4094.
default: Matches frames that do not match any other Ethernet service instance on the interface. On an interface, you can configure this criterion only in one Ethernet service instance. The Ethernet service instance matches any frames if it is the only instance on the interface.
tagged: Matches any frames that have an 802.1Q VLAN tag.
untagged: Matches any frames that do not have an 802.1Q VLAN tag.
Usage guidelines
The match criterion in each Ethernet service instance must be unique on an interface. For example, you cannot configure the encapsulation tagged command in one Ethernet service instance if another Ethernet service instance already contains this command. You cannot use the encapsulation s-vid vlan-id command to specify the same 802.1Q VLAN ID for any two Ethernet service instances on the interface.
An Ethernet service instance can contain only one match criterion. To change the match criterion, you must remove the original criterion first. When you remove the match criterion in an Ethernet service instance, the mapping between the service instance and the VSI is removed automatically.
To match frames from a VLAN correctly, make sure you have created the VLAN and assigned the interface to the VLAN.
If you set the match criterion to default or tagged, you must specify the Ethernet access mode when you configure the xconnect vsi command.
To match untagged frames when the VLAN access mode is used, you must use the encapsulation untagged command.
For more information about outer and inner 802.1Q VLAN IDs, see QinQ in Layer 2—LAN Switching Configuration Guide.
Examples
# Configure Ethernet service instance 1 on Ten-GigabitEthernet 1/0/1 to match frames that have an outer 802.1Q VLAN ID of 111 and an inner 802.1Q VLAN ID of 20.

Usage guidelines
By default, the device floods unknown unicast 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.
To confine unknown unicast traffic to the site-facing interfaces, use this command to disable the flooding function for the VSI bound to the VXLAN. The VSI will not flood unknown unicast frames to VXLAN tunnel interfaces.
Examples
# Disable flooding for the VSI vsi1.

group
Use group to assign a VXLAN a multicast group address for flood traffic, and specify a source IP address for multicast VXLAN packets.
Use undo group to restore the default.
Syntax
group group-address source source-address
undo group group-address source source-address
Default
A VXLAN uses unicast mode (head-end replication) for flood traffic. No multicast group address or source IP address is specified for multicast VXLAN packets.

mdc-admin
Parameters
group-address: Specifies a multicast address in the range of 224.0.1.0 to 239.255.255.255.
source source-address: Specifies a source IP address for multicast VXLAN packets.
Usage guidelines
To reduce traffic sent to the transport network, use multicast mode if the network has dense flood traffic or many VTEPs.
For traffic to be forwarded correctly, you must use the source IP address of an up VXLAN tunnel as the source IP address for multicast VXLAN packets. If the VXLAN has multiple VXLAN tunnels, the tunnels must use the same source IP address.
For multicast-mode VXLANs, transport network devices must maintain multicast group and forwarding information. To reduce the multicast forwarding entries maintained by transport network devices, assign a multicast group address to multiple VXLANs. The VTEP separates traffic between VXLANs by VXLAN IDs.
|
NOTE: For VXLANs that use the same multicast group address, you must configure the same source IP address for their multicast VXLAN packets. |
If you execute the group command multiple times for a VXLAN, the most recent configuration takes effect.
Examples
<Sysname> system-view
[Sysname] vsi aaa
[Sysname-vsi-aaa] vxlan 100

Usage guidelines
For this command to take effect, you must use the multicast routing command to enable IP multicast routing.
You must configure an interface as an IGMP host if its IP address is the source IP address of multicast VXLAN packets. The IGMP host function enables the interface to send IGMP reports in response to IGMP queries before it can receive traffic from a multicast group.
Examples
# Enable IP multicast routing, and then enable the IGMP host function on VLAN-interface 10.

Parameters
mac-address: Specifies a remote 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 the VXLAN tunnel interface for the remote MAC address. The tunnel-number argument represents the tunnel interface number. The tunnel interface must already exist.
vsi vsi-name: Specifies the 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 the following types:
· Static—Manually added MAC entries.
· Dynamic—MAC entries learned in the data plane from incoming traffic on VXLAN tunnels.
· OpenFlow—MAC entries issued by a remote controller through OpenFlow.
For a remote address, the manual static entry has higher priority than the dynamic entry.

Parameters
tunnel-number: Specifies a tunnel number in the range of 1 to 511. The tunnel must be a VXLAN 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.
You can assign multiple VXLAN tunnels to a VXLAN, and configure a VXLAN tunnel to trunk multiple VXLANs. For a unicast-mode VXLAN, the system floods unknown unicast, multicast, and broadcast traffic to each tunnel in the VXLAN.
If you use the tunnel all command to assign all VXLAN tunnels to a VXLAN, you cannot remove a single VXLAN tunnel from the VXLAN. You must remove all the VXLAN tunnels by using the undo tunnel all command.
Examples
# Assign VXLAN tunnel 1 to VXLAN 10000.
<Sysname> system
[Sysname] vsi vpna
[Sysname-vsi-vpna] vxlan 10000
[Sysname-vsi-vpna-vxlan-10000] tunnel 1

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. For BFD sessions to come up, you must also reserve a VXLAN by using the reserved vxlan command. 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.
Examples
# Specify VXLAN 10000 as the reserved VXLAN. Enable BFD on the VXLAN tunnel interface Tunnel 9, and specify 1-1-1 as the destination MAC address for BFD control packets.
<Sysname> system-view
[Sysname] reserved vxlan 10000

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
To use this command, you must first use the encapsulation command to add a traffic match criterion to the Ethernet service instance.
If you set the match criterion to default or tagged, you must specify the Ethernet access mode.
For traffic that matches the Ethernet service instance, 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.
Examples
# On Ten-GigabitEthernet 1/0/1, configure Ethernet service instance 200 to match frames with an outer 802.1Q VLAN tag of 200, and map the instance to the VSI vpn1.
