VXLAN commands

For Release 2416, VXLAN requires a license. For Release 2418P01 and later versions, VXLAN

does not require a license. For information about feature licensing, see Fundamentals Configuration

Guide.

Basic VXLAN commands

arp suppression enable

Use arp suppression enable to enable ARP flood suppression.

Use undo arp suppression enable to restore the default.

Syntax

arp suppression enable

undo arp suppression enable

Default

ARP flood suppression is disabled.

Views

VSI view

Predefined user roles

network-admin

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 for 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

Related commands

• display arp suppression vsi

• reset arp suppression vsi

description

Use description to configure a description for a VSI.

Use undo description to delete the description of a VSI.

Syntax

239.255.255.255. If you do not specify a multicast group, the command displays information about

all multicast groups.

interface interface-type interface-number: Specifies an interface by its type and number. If you do

not specify an interface, the command displays multicast group information for all interfaces.

verbose: Displays detailed multicast group information. If you do not specify this keyword, the

command displays brief multicast group information.

2418P01 and later versions.

• Down—The tunnel interface is down.

Type

Tunnel assignment method:

• Auto—The tunnel was automatically assigned to the VXLAN. For a

multicast-mode VXLAN, the tunnel (MTunnel) was automatically created and

assigned to the VXLAN to transmit flood traffic.

• Manual—The tunnel was manually assigned to the VXLAN.

Flooding proxy

Flood proxy state:

• Enabled—Flood proxy is enabled. The VTEP sends broadcast, multicast,

and unknown unicast traffic to a flood proxy server through the tunnel. The

flood proxy server replicates and forwards flood traffic to remote VTEPs.

• Disabled—Flood proxy is disabled.

ACs ACs that are bound to the VSI.

Link ID AC's link ID on the VSI.

State

AC state:

• Up.

• Down.

Parameters

vxlan-id: Specifies a VXLAN ID in the range of 0 to 16777215. If you do not specify a VXLAN, the

command displays VXLAN tunnel information for all VXLANs.

Examples

# Display VXLAN tunnel information for all VXLANs.

<Sysname> display vxlan tunnel

Total number of VXLANs: 1

VXLAN ID: 10, VSI name: vpna, Total tunnels: 4 (4 up, 0 down, 0 defect, 0 blocked)

Tunnel name Link ID State Type Flooding proxy

Tunnel0 0x5000000 Up Auto Disabled

Tunnel1 0x5000001 Up Manual Disabled

Tunnel2 0x5000002 Up Manual/Auto Disabled

MTunnel0 0x6002710 Up Auto Disabled

# Display VXLAN tunnel information for VXLAN 10.

<Sysname> display vxlan tunnel vxlan-id 10

VXLAN ID: 10, VSI name: vpna, Total tunnels: 4 (4 up, 0 down, 0 defect, 0 blocked)

Tunnel name Link ID State Type Flooding proxy

Tunnel0 0x5000000 Up Auto Disabled

Tunnel1 0x5000001 Up Manual Disabled

Tunnel2 0x5000002 Up Manual/Auto Disabled

Table 7 Command output

Field Description

Link ID Tunnel's link ID in the VXLAN.

State

Tunnel state:

• Up—The tunnel is operating correctly.

• Blocked—The tunnel is a backup proxy tunnel. Its tunnel interface is up, but the

tunnel is blocked because the primary proxy tunnel is operating correctly.

• Defect—The tunnel interface is up, but the VTEP has not received BFD control

packets from the remote end for 5 seconds. You must check for physical link or

VXLAN tunnel problems. This value is available in Release 2418P01 and later

versions.

• Down—The tunnel interface is down.

Type

Tunnel assignment method:

• Auto—The tunnel was automatically assigned to the VXLAN. For a

multicast-mode VXLAN, the tunnel (MTunnel) was automatically created and

assigned to the VXLAN to transmit flood traffic.

• Manual—The tunnel was manually assigned to the VXLAN.

Field Description

Flooding proxy

Flood proxy state:

• Enabled—Flood proxy is enabled. The VTEP sends broadcast, multicast, and

unknown unicast traffic to a flood proxy server through the tunnel. The flood

proxy server replicates and forwards flood traffic to remote VTEPs.

• Disabled—Flood proxy is disabled.

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

Releases 2416, 2418P01, and 2418P05:

encapsulation default

encapsulation { tagged | untagged }

encapsulation s-vid vlan-id [ only-tagged ]

undo encapsulation

Release 2422 and later versions:

encapsulation default

encapsulation { tagged | untagged }

encapsulation s-vid vlan-id [ only-tagged ]

encapsulation s-vid vlan-id c-vid vlan-id

undo encapsulation

Default

An Ethernet service instance does not contain a frame match criterion.

Views

Ethernet service instance view

Predefined user roles

network-admin

Parameters

default: Matches frames that do not match any other Ethernet service 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.

s-vid vlan-id: Matches frames that are tagged with the specified outer 802.1Q VLAN ID. The vlan-id

argument specifies a 802.1Q VLAN ID in the range of 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.

13

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. This option

is available in Release 2422 and later versions.

Usage guidelines

The match criterion in each Ethernet service instance on an interface must be unique. 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.

For Release 2422 and later versions, the encapsulation s-vid vlan-id [ only-tagged ] and

encapsulation s-vid vlan-id c-vid vlan-id commands can specify the same outer VLAN ID for two

Ethernet service instances on an interface. Frames that match both Ethernet service instances are

assigned to the Ethernet service instance configured by using the encapsulation s-vid vlan-id c-vid

vlan-id command.

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.

If the Ethernet service instance uses the default, tagged, or untagged frame match criterion, the

access mode set by the xconnect vsi command does not take effect. The VSI uses Ethernet access

mode to process traffic.

An SDN transport network uses a controller to deploy and manage VXLANs on VTEPs. If you

change the matching outer VLAN ID on the VTEP, you must also modify the VLAN ID set by the

Set-Field action on the controller.

Examples

# Configure Ethernet service instance 1 on FortyGigE 1/0/1 to match frames that have an outer

802.1Q VLAN ID of 111.

<Sysname> system-view

[Sysname] interface fortygige 1/0/1

[Sysname-FortyGigE1/0/1] service-instance 1

[Sysname-FortyGigE1/0/1-srv1] encapsulation s-vid 111
