Cisco NX-OS 7.3(0)D1(1)	This command was introduced.

Usage Guidelines

The access control list (ACL) matches the VXLAN OAM packets and sends the packets to the NGOAM module, else the ACL packets will be dropped by hardware.

Note

ACL is only required for leaf nodes to handle the packets.

Examples

The following example shows how to install NGOAM access control list using the ngoam install acl command.

switch(config-ng-oam-profile)# ngoam install acl

ngoam profile

To create VXLAN operations, administration, and maintenance (OAM) profile, use the ngoam profile command in global configuration mode.

To disable VXLAN OAM profile, use the no form of this command.

Release	Modification
Cisco NX-OS 7.3(0)N1(1)	This command was introduced.
Cisco NX-OS 7.3(0)D1(1)	This command was introduced.

Usage Guidelines

The NGOAM profiles provide a way to bundle the common NGOAM command parameters instead of specifying all the parameters in separate commands. For example, ping nve command. You can create these NGOAM profiles to store all the common parameters and specify the profile id instead of providing all the parameters in the command line.

Examples

The following example shows how to create a VXLAN OAM profile using the ngoam profile command.

ngoam profile 2
  oam-channel 2
  sport 12345, 54321

Create parameters for the specified parameter list using the define option.
Create an instance of a parameter list using the instance option.

Note

To view the define and instance options, type ? in parameter list configuration mode.

To configure parameters and parameter list instances for an existing parameter list, use the param-list parameter-list-name command, where parameter-list-name corresponds to an existing parameter list.

Examples

The following example shows how to create a user-defined parameter list named List1 and create a parameter named param1 within the list:

Device# configure terminal
Device(config)# param-list List1
Device(config-param-list)# define param1 integer 100
Device(config-param-list)# exit

The following examples shows how to view existing parameter lists:

Device# configure terminal
Device(config)# param-list ?


WORD               Enter the name of the parameter list (Max Size 80)
List2 (no abbrev)
List3 (no abbrev)

In the above example, List2 and List3 are the existing parameter lists. The following example shows how to add a parameter named param2 to List2:

Device(config)# param-list List2
Device(config-param-list)# define param2 integer 100
Device(config-param-list)# exit

Usage Guidelines

A route distinguisher (RD) creates routing and forwarding tables and specifies the default RD for a virtual private network (VPN). The RD is added to the beginning of your IPv4 prefixes to change them into globally unique VPN IPv4 prefixes.

This command automatically generates a type-1 route distinguisher (RD) for the VRF that is being configured. The value of the generated RD is router-id:vrf-id. If either, or both, the router-ID or VRF-ID is invalid, automatic generation of the RD fails.

No license is required for this command.

Examples

The following example shows how to configure a generated RD for the VRF instance "vpn1:"

vrf context vpn1
     rd auto

Command History

Release	Modification
Cisco NX-OS 5.2(1)	This command was introduced.
Cisco NX-OS 6.1(2)I2(2)	This command was integrated.
Cisco NX-OS 7.3(0)N1(1)	This command was integrated.

Usage Guidelines

In a VXLAN EVPN fabric, a tenant VRF (represented by a Layer-3 VNI) contains routes on different leaf switches (VTEPs). This command (along with the appropriate route-target command) ensures that all routes within a VRF are available with all the relevant VTEPs in the fabric.

Route-targets are used for enforcing appropriate policy with MP-BGP. Specifically, with explicit route-targets values attached to the prefixes from a given VRF, it is possible to control whether those prefixes should or should not be imported into the routing table of a remote leaf. Using the “route-target both auto evpn” command, route-target values are auto-generated for a given VRF, in the Cisco Programmable Fabric, using the autonomous sequence number and the Layer-3 VNI. The same route-target values for a VRF are shared by all the leaf nodes. In this way, all route prefixes in a given VRF are automatically imported/exported into/out of the routing tables of all the leaf nodes within the fabric.

Examples

The following example shows how to import and export tenant VRF routes from a switch:

switch(config-router)# VRF context vni-31000
switch(config-vrf)# vni 31000
switch(config-vrf)# rd auto 
switch(config-vrf)# address-family ipv4 unicast 
switch(config-vrf-af-ipv4)# route-target import 100:31000 evpn 
switch(config-vrf-af-ipv4)# route-target export 100:31000 evpn

server protocol

server protocol ldap { ip ip-address | host hostname } [ port port-number ] [ vrf vrf-name ]

no server protocol ldap { ip ip-address | host hostname } [ port port-number ] [ vrf vrf-name ]

Syntax Description

ldap	Specifies that LDAP is configured.
ip ip-address	Specifies the IP address of the server.
host hostname	Specifies the hostname and DNS names of the server.
port port-number	(Optional) Specifies the TCP or UDP port number on the server.
vrf vrf-name	(Optional) Specifies the virtual routing and forwarding context to use to connect to the server.

Command Default

The protocol for a server group is not configured.

suppress-arp

To suppress ARP requests at the leaf switch or ToR layer and minimize flooding in the VXLAN EVPN fabric, use the suppress-arp command in the NVE VNI interface configuration mode. To remove the ARP suppression function on a leaf switch, use the no form of the command.

suppress-arp

no suppress-arp

Syntax Description

This command has no arguments or keywords.

Command Default

ARP requests are not suppressed.

Command Modes

NVE VNI interface configuration (config-if-nve-vni)

Command History

Release	Modification
Cisco NX-OS 7.3(0)N1(1)	This command was introduced.
Cisco NX-OS 7.3(0)D1(1)	This command was introduced.

Usage Guidelines

ARP suppression is an enhanced function configured under the layer-2 VNI using this command. Essentially, the IP-MACs learnt locally via ARP as well as those learnt over BGP-EVPN are stored in a local ARP suppression cache at each ToR. An ARP request sent from an end host is trapped at the source ToR. A lookup is performed in the ARP suppression cache with the destination IP as the key. If there is a HIT, then the ToR proxies on behalf of the destination with the destination MAC.

In case the lookup results in a MISS, when the destination is unknown or a silent end host, the ToR re-injects the ARP request received from the requesting end host and broadcasts it within the layer-2 VNI, across the fabric. Assuming that the destination is alive, the ARP request will reach the destination ToR, which in turn will send out an ARP response toward the sender. In addition, the destination IP/MAC is advertised over BGP-EVPN to all ToRs.

Examples

The following example shows how to suppress ARP requests in a VXLAN EVPN fabric:

switch(config)# interface nve 1
switch(config-if-nve)# member vni 6001 
switch(config-if-nve-vni)# suppress-arp

suppress-unknown-unicast

To restrict flooding of unknown unicast packets from an end host to other end host ports that are local to the attached ToR/leaf switch, and ensure that the packets are not flooded into the VXLAN fabric, use the suppress-unknown-unicast command in the NVE VNI interface configuration mode.

To remove the unknown unicast suppression function on the ToR switch, use the no form of the command.

suppress-unknown-unicast

no suppress-unknown-unicast

Syntax Description

This command has no arguments or keywords.

Command Default

Unknown unicast packets are not restricted from flooding the VXLAN EVPN fabric.

Command Modes

NVE VNI interface configuration (config-if-nve-vni)

Command History

Release	Modification
Cisco NX-OS 7.3(0)N1(1)	This command was introduced.
Cisco NX-OS 7.3(0)D1(1)	This command was introduced.

Usage Guidelines

The suppress unknown unicast function is supported on ToRs/VTEPs in a VXLAN EVPN fabric. Unknown unicast traffic from an end host is by default flooded in the (Layer 2 VNI associated?) VLAN. It is possible to avoid the flooding of this traffic to the overlay network without affecting the flooding of this traffic on local host/sever ports attached to the ToR switch. This is achieved by enabling this command.

The suppress unknown unicast function allows flooding of traffic within the attached switch by including local host/server ports attached to the ToR switch in the output interface index flood list (OIFL) and excluding overlay L3 ports in the (should I include a mention of L2 ports, since bridging unknown unicast packets is also restricted? Or is my understanding incorrect?) hardware. So, an ARP request is not sent at all in this case? Right?

Examples

The following example shows how to restrict flooding of unknown unicast packets to other end host ports that are local to the attached ToR/leaf switch:

switch(config)# interface nve 1
switch(config-if-nve)# member vni 6001 
switch(config-if-nve-vni)# suppress-unknown-unicast

system fabric core-vlans

To define the core-facing set of dynamic allocatable VLANs for Cisco Programmable Fabric, use the system fabric core-vlans command in global configuration mode. To remove the VLAN reservation, use the no form of this command.

system fabric core-vlans { vlan-id | vlan-range }

no system fabric core-vlans

Syntax Description

vlan-id

Unique identifier (ID) for a core VLAN. The range is from 1 to 4094.

vlan-range

Range of VLAN IDs for core VLANs.

The vlan-range argument can any of the following:

A list of VLAN IDs separated by commas (,)
A range of VLAN IDs separated by a hyphen (-), such as vlan-id - vlan-id
A combination of VLAN IDs and VLAN ranges

Multiple entries must be separated by a comma (,).

Command Default

Range of core-facing dynamic VLANs for Cisco Programmable Fabric are undefined.

Command Modes

Global configuration (config)

Command History

Release	Modification
Cisco NX-OS 7.0(0)N1(1)	This command was introduced.

Usage Guidelines

The core-VLAN range is a subset of VLANs from the dynamic-VLAN range. Core VLANs are used by Cisco Programmable Fabric auto configuration to map the virtual network identifier (VNI) that is configured under virtual routing and forwarding (VRF). Cisco Programmable Fabric dynamically chooses a VLAN from the core-VLAN range to create the core- facing SVI for the tenant VRF. The VNI-to-VLAN mapping is one to one.

Use this command to identify the set of VLANs that are to be used for core-facing interfaces. The range must be large enough to accommodate the number of tenant VRFs that you expect to deploy.

This command must be configured on each Cisco Programmable Fabric Layer-3 leaf switch in your Cisco Programmable Fabric deployment.

The number of VLANs in the set of core VLANs can be modified (expanded or reduced) by using this command, and the no form of this command, as long as there are no active VLANs in the VLAN range being configured.

All VLANs that you specify by using this command must be a subset of the dynamic VLANs that you defined by using the system fabric dynamic-vlans command.

System-fabric core VLANs must never be used on host-facing switch ports and cannot be used for a mobility domain.

The no version of this command removes the reservation, not the VLANs. The no system fabric core-vlans command can remove the reservation only if there are no active VLANs in the range of VLANs. Delete all active VLANs that are in the VLAN range before removing the reservation.

Before using this command, you must first enable fabric network services on the device by using the feature fabric forwarding command.

This command is supported on Cisco Programmable Fabric Layer-3 leaf switches only. This command is not supported on Cisco Nexus 5500 Series switches configured as Cisco Programmable Fabric Layer-2-only leaf switches.

Examples

The following example shows how to specify the dynamic core-VLAN range:

switch> enable
switch# configure terminal
switch(config)# install feature-set fabric
switch(config)# feature-set fabric
switch(config)# feature fabric forwarding
switch(config)# system fabric dynamic-vlans 2500-3500
switch(config)# system fabric core-vlans 2900-2999

system fabric dynamic-vlans

To define a global set of dynamic allocatable VLANs for Cisco Programmable Fabric, use the system fabric dynamic-vlans command in global configuration mode. To remove the reservation, use the no form of this command.

system fabric dynamic-vlans { vlan-id | vlan-range }

no system fabric dynamic-vlans

Syntax Description

vlan-id

Unique identifier (ID) for a dynamic VLAN. The range is from 1 to 4094.

vlan-range

Range of VLAN IDs for dynamic VLANs.

The vlan-range argument can any of the following:

A list of VLAN IDs separated by commas (,)
A range of VLAN IDs separated by a hyphen (-), such as vlan-id - vlan-id
A combination of VLAN IDs and VLAN ranges

Multiple entries must be separated by a comma (,).

Note

The dynamic-VLAN range need not be contiguous, however, we recommend that it is.

Command Default

Range of dynamic VLANs for Cisco Programmable Fabric are undefined.

Command Modes

Global configuration (config)

Command History

Release	Modification
Cisco NX-OS 7.0(0)N1(1)	This command was introduced.

Usage Guidelines

Cisco Programmable Fabric dynamically provisions server- and host-facing, and core-facing switch virtual interfaces (SVIs) for tenants. VSI Discovery and Configuration Protocol (VDP) dynamically-derived VLANs are used by Cisco Programmable Fabric for the server and core provisioning. The VLANs to be used for the SVIs must be specified. There are two VLAN ranges for Cisco Programmable Fabric:

The dynamic-VLAN range is the global set of server, host, and core VLANs.
The core-VLAN range is a subset of VLANs from the dynamic-VLAN range. The core VLANs are for the core SVIs. For information, see the system fabric core-vlans.

Use this command to identify the complete range of dynamic allocatable VLANs for Cisco Programmable Fabric, including server- and host-facing VLANs and core-facing VLANs.

Do not configure internal VLANs and active or already-created VLANs as dynamic VLANs.

VLANs used in a mobility domain cannot be part of the dynamic-VLAN range.

The number of VLANs in the set of dynamic VLANs can be modified (expanded or reduced) by using this command, and the no form of this command, as long as there are no active VLANs in the VLAN range being configured.

If you have already configured the system fabric core-vlans command, the range of VLANs that you configure by using this command must be a superset of the core-VLAN range.

The no version of this command removes the reservation, not the VLANs. The no system fabric dynamic-vlans command can remove the reservation only if there are no active VLANs in the range of VLANs. Delete all active VLANs that are in the VLAN range before removing the reservation.

Before using this command, you must first enable fabric network services on the device by using the feature fabric forwarding command.

This command is supported on Cisco Programmable Fabric Layer-3 leaf switches only. This command is not supported on Cisco Nexus 5500 Series switches configured as Cisco Programmable Fabric Layer-2-only leaf switches.

Examples

The following example shows how to reserve a set of dynamic VLANs:

switch> enable
switch# configure terminal
switch(config)# install feature-set fabric

Usage Guidelines

You can configure only one VRF instance for a server group.

Use the aaa group server radius command to enter RADIUS server group configuration mode, the aaa group server tacacs+ command to enter TACACS+ server group configuration mode, or the aaa group server ldap command to enter LDAP server group configuration mode.

If the server is not found, use the radius-server host command, the tacacs-server host command, or the ldap-server host command to configure the server.

Note

You must use the feature tacacs+ command before you configure TACACS+ or the feature ldap command before you configure LDAP.

This command does not require a license.

Examples

This example shows how to specify a VRF name for a RADIUS server group:

Device# configure terminal
Device(config)# aaa group server radius RadServer
Device(config-radius)# use-vrf vrf1

This example shows how to specify a VRF name for a TACACS+ server group:

Device(config)# feature tacacs+
Device(config)# aaa group server tacacs+ TacServer
Device(config-tacacs+)# use-vrf vrf2

This example shows how to remove the VRF name from a TACACS+ server group:

Device(config)# feature tacacs+
Device(config)# aaa group server tacacs+ TacServer

Usage Guidelines

You can use the vdc switch command only with the specific Virtual Device Context (VDC) identifier value of 1. The VDC type storage cannot be the default VDC, and it can be only one of the VDCs. You cannot have two type storage VDCs on the device. When you create or specify a VDC, the Cisco NX-OS software allocates the internal resources for the VDC. This process can take a few minutes to complete depending on the amount of internal resource you have requested for the VDC.

Examples

The following example shows how to specify a Virtual Device Context (VDC) for a switch:

Device> enable
Device# configure terminal
Device (config)# vdc switch 
Device(config-vdc)# end

The following example shows how to force a VDC into a specific ID <1>:

Device> enable
Device# configure terminal
Device (config)#  vdc switch id 1
Device(config-vdc)# end

The following example shows how to force a VDC into a specific ID <1>:

Device> enable
Device# configure terminal
Device(config)# vdc switch type storage
Device(config)# end
