encapsulation
Use encapsulation to configure a frame match criterion for an Ethernet service instance.
Use undo encapsulation to restore the default.
Syntax
encapsulation s-vid vlan-id-list [ only-tagged ]
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
context-admin
Parameters
s-vid: Matches frames that are tagged with the specified outer 802.1Q VLAN IDs.
vlan-id: Specifies an 802.1Q VLAN ID in the range of 1 to 4094.
vlan-id-list: Specifies a space-separated list of up to eight VLAN items. Each item specifies a VLAN ID or a range of VLAN IDs in the format of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094.
only-tagged: Matches tagged frames. 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.
· To match only PVID-tagged frames, specify the only-tagged keyword.
· To match both untagged frames and PVID-tagged frames, do not specify the only-tagged keyword.
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
An Ethernet service instance can contain only one match criterion. To change the match criterion, first execute the undo encapsulation command to remove the original criterion. When you remove the match criterion in an Ethernet service instance, the mapping between the service instance and the VSI is removed automatically.
Examples
# Configure Ethernet service instance 1 on GigabitEthernet 1/0/1 to match frames that have an outer 802.1Q VLAN ID of 111.
<Sysname> system-view

Parameters
size: Specifies an MTU value. The value range for this argument is 300 to 65535.
Usage guidelines
The MTU set by using this command limits the maximum length of the packets that a VSI receives from ACs and forwards through VXLAN tunnels. The MTU does not limit the maximum length of other packets in the VXLAN VSI.
Fragmentation is disabled for a VSI that uses the default MTU. If you set a MTU for a VSI, the packets longer than the MTU are fragmented.
Examples
# Set the MTU to 1400 bytes for VSI vxlan1.

Predefined user roles
network-admin
context-admin
Parameters
tunnel-number: Specifies a tunnel interface number. The value range for this argument is 0 to 1023. 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.
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.
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 modify the flood proxy setting on a VXLAN tunnel, you must first use the undo tunnel command to remove the tunnel.
Examples
# Assign VXLAN tunnels 1 and 2 to VXLAN 10000.
<Sysname> system-view
[Sysname] vsi vpna
[Sysname-vsi-vpna] vxlan 10000

Views
System view
Predefined user roles
network-admin
context-admin
Usage guidelines
VXLAN fast forwarding enables the device to bypass QoS and security services when the device forwards data traffic over VXLAN tunnels based on the software. As a best practice, enable this feature to improve forwarding speed only when QoS and security services are not configured on the following interfaces:
· VSI interfaces.
· Traffic outgoing interfaces for VXLAN tunnels.
When VXLAN fast forwarding is enabled, a VXLAN tunnel cannot use ECMP routes to load share traffic. Instead, it selects one route from the ECMP routes to forward VXLAN packets.
Examples
# Enable VXLAN fast forwarding.
<Sysname> system
[Sysname] vxlan fast-forwarding enable
vxlan invalid-udp-checksum discard
Use vxlan invalid-udp-checksum discard to enable the device to drop the VXLAN packets that fail UDP checksum check.
Use undo vxlan invalid-udp-checksum discard to restore the default.
Syntax

Predefined user roles
network-admin
context-admin
Usage guidelines
This command enables the device to check the UDP checksum of VXLAN packets.
The device always sets the UDP checksum of VXLAN packets to 0. For compatibility with third-party devices, a VXLAN packet can pass the check if its UDP checksum is 0 or correct. If its UDP checksum is incorrect, the VXLAN packet fails the check and is dropped.
Examples
# Enable the device to drop the VXLAN packets that fail UDP checksum check.

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 } ] [ track track-entry-number&<1-3> ]
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. If the AC is an Ethernet service instance or Layer 3 subinterface, you can specify this keyword. The default access mode is VLAN. If the AC is a Layer 3 interface, you cannot specify this keyword.
ethernet: Specifies the Ethernet access mode.
vlan: Specifies the VLAN access mode.
track track-entry-number&<1-3>: Specifies a space-separated list of up to three track entry numbers in the range of 1 to 1024. The AC is up only if a minimum of one associated track entry is in positive state.
Usage guidelines
For traffic that matches a Layer 3 interface, the system uses the VSI's MAC address table to make a forwarding decision.
For traffic that matches an Ethernet service instance on an interface, the system uses the VSI's MAC address table to make a forwarding decision.
To execute this command for an Ethernet service instance, you must first use the encapsulation command to add a traffic match criterion to the service instance.
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.
After you modify the access mode on a Layer 3 subinterface AC, local VMs that access the VXLAN network through the subinterface cannot communicate with remote VMs. To resolve this issue, you must clear the ARP entries on the local VMs or configure them to periodically send gratuitous ARP packets.
