peer-type
To classify a neighbor as external to the Cisco Dynamic Fabric Automation (DFA) fabric and avoid advertising externally learned prefixes to fabric-internal neighbors, use the peer-type command. To return to the default, use the no form of this command.
peer-type { fabric-border-leaf | fabric-external }
no peer-type { fabric-border-leaf | fabric-external }
Syntax Description
fabric-border-leaf |
Specifies that all border leaf switches on the Cisco DFA fabric are peers to other border-leaf switches. |
fabric-external |
Specifies that a neighbor is marked as fabric external |
Command Default
A neighbor is classified as internal to the fabric.
Command Modes
BGP neighbor configuration (config-router-neighbor)
Command History
Release | Modification |
---|---|
7.0(0)N1(1) |
This command was introduced. |
Usage Guidelines
A Cisco DFA border-leaf switch always advertises all learned prefixes outside the Cisco DFA fabric, even those that are host-routes.
An external route is not advertised to the fabric-internal neighbors unless there an internal route that is less specific than the external route.
Use the peer-type command to classify a Border Gateway Protocol (BGP) neighbor as external to the fabric. The border leaf must specifically classify external neighbors in order to apply the appropriate rules of route exchange between internal and external neighbors and avoid advertising externally learned prefixes to fabric-internal neighbors through internal BGP. For example, when an update from a fabric-internal neighbor goes to an external neighbor, the virtual network identifier (VNI) is stripped and the fabric site of origin (SoO) extended community value in the BGP update message is attached. For routes coming from external neighbors, the fabric SoO is used to check for loops and to perform the appropriate filtering of routes from external neighbors to internal neighbors.
This command applies only to border-leaf switches.
This command is required on the border-leaf switch for external neighbors.
This command is not supported on Cisco Nexus 5500 Series switches configured as DFA Layer 2-only leaf switches.
Examples
The following example shows how to configure the neighbor configuration on a border leaf-towards-Data Center Interconnect (DCI) node:
router bgp 1 neighbor 30.1.1.1 remote-as 2 description default vrf neighbor to DCI peer-type fabric-external send-community extended

Usage Guidelines
This command is operational only if the Dynamic Virtual Port (dVP) feature is operational. See the system default trunk allocate vlan dynamic command for more information.
The system default trunk allocate vlan dynamic configuration is the default state on all Layer-2 trunk ports. However, the default state has no significance if the dVP feature is nonoperational.
You can configure the system default trunk allocate vlan dynamic command on Layer-2 ports whether the port is in the access, FEX, or fabric mode. However, the configuration is effective in trunk mode only.
Use this command to start the dynamic logical interface feature after the feature has been explicitly disabled at the interface level.
No license is required for this command.

7.1(0)N1(1) |
This command was introduced. |
Usage Guidelines
This command is supported only on the leaf switches in a Cisco Dynamic Fabric Automation (DFA) deployment.
Note | The CLI configuration is saved after you issue this command, but the dVP feature is (operationally) enabled or disabled only after the switch configuration is saved and the switch is rebooted. |
A logical interface (LI) is created when a VLAN is activated on the port of a switchport. Whenever a VLAN is created in the system, it brings up virtual ports on all the access and trunk switchports. On access ports, a single virtual port comes up if the created VLAN is configured as the access VLAN of a port. However, the default behavior for trunk ports is to bring the virtual port up on all of the created VLANs that are in the allowed VLAN list.
For example, assume there are 10 trunks. By default, configuring the vlan 300-400 command creates virtual ports for VLAN 300 to 400 on all the 10 trunks. In a typical Cisco DFA deployment with up to 1500 VLANs (including core, server, and other VLANs) and 100 trunks, the scalability limits for (port, vlan) on the switch can be exceeded. The dVP feature limits the created virtual ports to a trunk port or port channel on which traffic is received in the system, and eliminates this risk on a leaf switch in a Cisco DFA deployment.
Note | The CLI configuration is saved after you issue the system default trunk allocate vlan dynamic command, but the dVP feature is (operationally) enabled or disabled only after the switch configuration is saved and the switch is rebooted. |
No license is required for this command.
Examples
The following example shows how to configure the dVP feature:
switch(config-term)# system default trunk allocate vlan dynamic
The following sample output from the system default trunk allocate vlan dynamic command shows that the dVP feature is not yet operational. The feature will be operational only after the switch configuration is saved and the switch is rebooted.
switch# show system trunk dynamic status Global Status ------------- Configured : Enabled (Will take effect on reboot) Operational : Disabled Number of operationally enabled dynamic logical interfaces : 0

system fabric core-vlans
To define the core-facing set of dynamic allocatable VLANs for Cisco Dynamic Fabric Automation (DFA), 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. Multiple entries must be separated by a comma (,). |
Command Default
Range of core-facing dynamic VLANs for Cisco DFA are undefined.
Command Modes

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 DFA auto configuration to map the virtual network identifier (VNI) that is configured under virtual routing and forwarding (VRF). Cisco DFA 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 DFA Layer 3 leaf switch in your Cisco DFA 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 DFA Layer 3 leaf switches only. This command is not supported on Cisco Nexus 5500 Series switches configured as DFA Layer 2-only leaf switches.
Examples
The following example shows how to specify the dynamic core-VLAN range:
Device> enable Device# configure terminal Device(config)# install feature-set fabric Device(config)# feature-set fabric Device(config)# feature fabric forwarding Device(config)# system fabric dynamic-vlans 2500-3500 Device(config)# system fabric core-vlans 2900-2999

Usage Guidelines
-
The dynamic-VLAN range is the global set of server, host, and core VLANs. Cisco DFA dynamically chooses a VLAN from the dynamic-VLAN range to map the virtual network identifier (VNI) to both the FabricPath VLAN on a leaf switch and the corresponding server-facing SVI. The VNI-to-VLAN mapping is one to one.
-
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 Dynamic Fabric Automation (DFA), 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 DFA Layer 3 leaf switches only. This command is not supported on Cisco Nexus 5500 Series switches configured as DFA Layer 2-only leaf switches.
Examples
The following example shows how to reserve a set of dynamic VLANs:

Usage Guidelines
Use the system fabric global-mobility-domain command to configure detectable VLANs on a switch for which auto-configuration can be done. Detectable VLANs configured under this range can be auto-detected on all interface, which belongs to default (global) mobility domain. The global mobility domain must be configured before any of the other mobility domains. All L2 CE access/trunk ports become part of this mobility domain automatically.
The mobility domain commands must be issued only if multiple mobility domains are required on the switch. If a single mobility domain (the global mobility domain) is adequate to meet the deployment needs, issuing the system fabric global-mobility-domain detectable-vlans is optional and should be considered only when fine control on the set of VLANs that can be auto-detected is needed. The detectable VLANs set must include the trunk native VLANs for correct switch operation.
Examples
The following example shows how to create global mobility domain by specifying a VLAN ID using the system fabric global-mobility-domain command:
Device(config)# system fabric global-mobility-domain detectable-vlans 200-998

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

— |
This command was introduced in a release earlier than Cisco NX-OS Release 7.0(0)N1(1). |
7.0(0)N1(1) |
This command was modified. The sequence-number argument was removed. |
Usage Guidelines
Each VLAN access-map entry can include one action command and one or more match commands. Use the statistics per-entry command to configure the device to record statistics for a VLAN access-map entry.
Use the vlan access-map command to enter the access-map configuration mode (config-access-map) to enable receiving of packets on any port on the switch. PowerOn Auto Provisioning (POAP) uses access control 3ists (ACL) to selectively receive packets. All line cards supported by N7K support Layer 2 ports. Therefore, for the purpose of PoAP, all ports are configured as Layer 2 ports. To simplify configuration of ACLs, a common VLAN is allowed on all the ports and the VLAN ACL (VACL) configured on this common VLAN.
The VACL is configured in two phases. Initially, the VACL will be configured to permit just the DHCP requests and responses and redirect these to the supervisor. All other packets will be dropped. The permit rules match DHCP requests and responses. They make use of the fact that DHCP uses UDP and fixed L4 port numbers for the server (67) and client (68). Once the PoAP process receives the appropriate DHCP packets and an IP address is assigned to the switch, the VACL will be modified to permit all packets destined to the newly assigned IP address.
This command does not require a license.
Examples
The following example shows how to enable and configure a VLAN access-map entry:
Device> enable Device# configure terminal Device(config)# ip access-list testacl Device(config-acl)# 20 permit udp any any eq 67 Device(config-acl)# 30 permit udp any any eq 68 Device(config-acl)# 40 permit udp any eq 67 any Device(config-acl)# 50 permit udp any eq 68 any Device(config-acl)# 60 deny ip any any Device(config-acl)# exit Device(config)# vlan access-map poapvacl Device(config-access-map)# match ip address testacl Device(config-access-map)# end
