vcf-fabric role

Use vcf-fabric role to specify the role of the device.

Use undo vcf-fabric role to restore the default.

Syntax

vcf-fabric role { access | aggr | leaf | spine }

undo vcf-fabric role

Default

The device is a leaf node.

Predefined user roles

network-admin

mdc-admin

Parameters

access: Specifies the access node.

aggr: Specifies the aggregate node.

leaf: Specifies the leaf node.

spine: Specifies the spine node.

Usage guidelines

If you change the role of the device, the new role takes effect after the device restarts.

User-defined MDCs do not have a role by default. You can use this command to specify the role for the MDCs. Automated underlay network provisioning is not supported by user-defined MDCs. The Director server can identify the role of user-defined MDCs in the VCF fabric and deploy configuration to the MDCs through NETCONF.

Examples

# Specify the device as a spine node.

<Sysname> system-view

[Sysname] vcf-fabric role spine

vcf-fabric spine-role master

Use vcf-fabric spine-role master to specify the device as a master spine node.

Use undo vcf-fabric spine-role master to restore the default.

Syntax

vcf-fabric spine-role master

undo vcf-fabric spine-role

Default

The device is not a master spine node.

Views

System view

Predefined user roles

network-admin

Usage guidelines

You must execute this command on a spine node.

When multiple spines nodes exist in the VCF fabric, you must specify a device as the master spine node to collect the topology for the entire VCF fabric.

For the new role to take effect, you must restart the automated underlay network deployment. To restart the automated underlay network deployment, execute the undo vcf-fabric underlay autoconfigure command and then the vcf-fabric underlay autoconfigure command.

Examples

# Specify the device as a master spine.

<Sysname> system-view

[Sysname] vcf-fabric spine-role master

For this configuration to take effect, you must execute the undo vcf-fabric underlay autoconfigure and vcf-fabric underlay autoconfigure commands in sequence.

Predefined user roles

network-admin

Parameters

template: Specifies a template file by its name, a case-insensitive string of 1 to 127 characters. A template file is a file ending with the .template file extension.

Usage guidelines

After this command is executed, the device uses the specified template file to deploy the underlay network.

If you re-execute this command after automated underlay network deployment is cancelled, the spine node will assign different IP addresses to loopback interfaces on leaf nodes. Thus, the leaf nodes will go offline and come online again.

Examples

# Specify template file vlan_leaf.template for automated underlay network deployment.

<Sysname> system-view

[Sysname] vcf-fabric underlay autoconfigure vlan_leaf.template

vcf-fabric underlay netconf-username

Use vcf-fabric underlay netconf-username to set the NETCONF username.

Use undo vcf-fabric underlay netconf-username to restore the default.

Syntax

vcf-fabric underlay netconf-username username

undo vcf-fabric underlay netconf-username

Default

The device uses the NETCONF username defined in the template file for automated VCF fabric deployment.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

username: Specifies the username used by the spine device to collect the global topology through NETCONF, a case-sensitive string of 1 to 63 characters.

Usage guidelines

This command is available on spine nodes.

During automated underlay network deployment, a spine node establishes NETCONF sessions with other devices in the underlay network to collect the global topology. If a user changes the username or password on a device in the undelay network, the NETCONF session between the device and the spine node is disconnected. Thun, the spine node fails to sense the topology change. To resolve the issue, use this command to change the NETCONF username on the spine node.

Make sure all devices in the underlay network use the same username and password for NETCONF session establishment.

Examples

# Set the NETCONF username to aaa.

<Sysname> system-view

[Sysname] vcf-fabric underlay netconf-username aaa

vcf-fabric underlay netconf-password

Use vcf-fabric underlay netconf-password to set the NETCONF password.

Use undo vcf-fabric netconf-underlay password to restore the default.

Syntax

vcf-fabric underlay netconf-password { cipher | simple } string

undo vcf-fabric underlay netconf-password

Default

The device uses the NETCONF password defined in the template file for automated VCF fabric deployment.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

cipher: Specifies the password in encrypted form.

simple: Specifies the password in plaintext form. For security purposes, the password specified in plaintext form will be stored in encrypted form.

string: Specifies the key. This argument is case sensitive. Its plaintext form is a string of 1 to 63 characters. Its encrypted form is a string of 1 to 127 characters.

Usage guidelines

This command is available on spine nodes.

During automated underlay network deployment, a spine node establishes NETCONF sessions with other devices in the underlay network to collect the global topology. If a user changes the username or password on a device in the undelay network, the NETCONF session between the device and the spine node is disconnected. Thun, the spine node fails to sense the topology change. To resolve the issue, use this command to change the NETCONF password on the spine node.

Make sure all devices in the underlay network use the same username and password for NETCONF session establishment.

Examples

# Set the NETCONF password to aaa in plaintext form.

<Sysname> system-view

[Sysname] vcf-fabric underlay netconf-password simple aaa

vcf-fabric underlay pause

Use vcf-fabric underlay pause to pause automated underlay network deployment.

Use undo vcf-fabric underlay pause to continue automated underlay network deployment.

Syntax
