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:

plb

To create a PLB service instance and parameters for it, use the plb command in global configuration mode. To remove a PLB service instance, use the no form of the command.

plb service-instance

no plb service-instance

Syntax Description


`service-instance`	PLB service instance.

Command Default

A pervasive load balancing (PLB) service instance is not enabled by default.

Command Modes

Global configuration (config)

Command History


Release	Modification
Cisco NX-OS 8.0(1)	This command was introduced.

Usage Guidelines

After creating a PLB service instance, the following associations should be made with it:

—A virtual IP address (VIP) should be created for load balancing server traffic for the service. Client packets contain the VIP as the destination IP address, and not the server IP address.

—The shadow BDI should be assigned for the device group.

—A load balancing mask should be applied to identify the correct bucket for load balancing.

The plb option is also used in other command forms such as plb l3-device-group (used for creating a PLB device group) and plb statistics . For better usability, the options have been documented as separate commands

Examples

This example shows how to create a PLB service instance and parameters for the service instance:


switch (config) # plb srv200 
switch (config-plb) # l3-device-group dg200
switch (config-plb) # virtual ip 200.200.200.200 255.255.255.255
switch (config-plb) # ingress interface Bdi1810 
switch (config-plb) # load-balance buckets 4 mask-position 10
switch (config-plb) # no shutdown

The ingress interface option is used for creating the shadow BDI.

Related Commands


Command	Description
plb l3-device-group	Creates a PLB device group for balancing server or appliance loads.
plb statistics	Enables PLB statistics function.
show plb statistics	Displays PLB statistics.

plb l3-device-group

To create a PLB device group for balancing server or appliance loads, use the plb l3-device-group command in global configuration mode. To disable the device group, use the no form of the command.

plb l3-device-group name

no plb l3-device-group name

Syntax Description


`name`	PLB device group name.

Command Default

A pervasive load balancing (PLB) device group is not enabled by default.

Command Modes

Global configuration (config)

Command History


Release	Modification
Cisco NX-OS 8.0(1)	This command was introduced.

Usage Guidelines

The PLB device group consists of Layer-3 load balancing server or appliance nodes. After you create the device group, use the node ip IP-address command form to add IP addresses of the servers/appliances that you want to add to the group.

Examples

This example shows how to create a PLB device group and associate servers/appliances to it:


switch (config) # plb l3-device-group dg200
switch (config-device-group) # node ip 10.10.10.120
switch (config-device-group) # node ip 10.10.10.121

weight option—After specifying a node and its IP address, you can specify a proportionate weight for the node for weighted traffic distribution.

Since device groups are also formed for a group of servers that cater to a service, you can use the service as the device group name (for example, DNS).

Related Commands


Command	Description
plb	Creates a PLB service instance and parameters for it.
show plb statistics	Displays PLB statistics.

plb statistics

To enable PLB statistics function, use the plb statistics command in global configuration mode. To disable PLB statistics function, use the no form of the command.

plb statistics service-instance

no plb statistics service-instance

Syntax Description

Command Default

PLB service instance statistics is not available for users by default.

Command Modes

Global configuration (config)

Command History


Release	Modification
Cisco NX-OS 8.0(1)	This command was introduced.

Usage Guidelines

The statistics include the service instance, the device group that is tied to the service, the VIP that represents the device group (of servers and appliances) across the fabric, etc.

Examples

This example shows how to enable PLB service instance statistics for the service instance:


switch (config) # plb statistics srv200

Related Commands


Command	Description
plb	Creates a PLB service instance and parameters for it.
plb l3-device-group	Creates a PLB device group for balancing server or appliance loads.

Command History


Release	Modification
Cisco NX-OS 7.0(0)N1(1)	This command was introduced.
Cisco NX-OS 7.2(0)D1(1)	This command was integrated.

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

To configure Lightweight Directory Access Protocol (LDAP) for a server group, use the server protocol command in fabric database configuration mode. To disable the configuration, use the no form of this command.

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

Unknown unicast traffic from an end host is by default flooded in the VLAN. To avoid the flooding of traffic to the overlay network without affecting the flooding of traffic on local host or on sever ports attached to the ToR switch, you must use the suppress-unknown-unicast command.

The suppress unknown unicast function allows flooding of traffic within the attached switch by including local host or server ports attached to the ToR switch in the output interface index flood list (OIFL) and excluding overlay Layer 3 ports in the hardware.

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
switch(config)# feature-set fabric
switch(config)# feature fabric forwarding
switch(config)# system fabric dynamic-vlans 2500-3500

traceroute nve

To discover the network virtualization endpoint's route, use the traceroute nve command in privileged EXEC mode.

traceroute nve { ip ip-adddress|mac mac-adddress} profile id [ vrf |vni count number]

Syntax Description


ip `ip-adddress`	IP address of the destination host.
mac `mac-adddress`	MAC address of the destination host.
profile `id`	Name of the profile.
vrf	The tenant VRF, where this tenant IP-address reside.
vni	The valid VNI present in the VTEP.
