Enhanced Role-based Access Control

Starting from SAN Controller Release 12.0.1(a), all RBAC is in Nexus Dashboard. User-roles and access are defined from Nexus Dashboard for fabrics on NDFC.

Nexus Dashboard admin role is considered as Network-admin role in NDFC.

DCNM had five roles to perform various access and operations. If a user is access a fabric with network stage role has access to all other fabrics as a network stage role. Therefore, a username is restricted with their role in DCNM.

Cisco NDFC Release 12.0.1(a) has same five roles but you can do granular RBAC with integration of Nexus Dashboard. If a user accesses a fabric as a network stage role, the same user can access different fabric with other user role such as admin or operator role. Therefore, a user can have different access on the different fabrics in NDFC.

NDFC RBAC supports following roles:

NDFC Access Admin
NDFC Device Upgrade Admin
NDFC Network Admin
NDFC Network Operator
NDFC Network Stager

The following table describes the user roles and their privileges in NDFC.


Roles	Privileges
NDFC Access Admin	Read/Write See
NDFC Device Upgrade Admin	Read/Write
NDFC Network Admin	Read/Write
NDFC Network Operator	Read
NDFC Network Stager	Read/Write

The following roles are supported on DCNM for backward compatibility:

SAN admin (mapped to network-admin)
Global-admin (mapped to network-admin)
SAN network-admin (mapped to network-admin)
Server-admin (mapped to network-admin)

Note

In any window, the actions that are restricted by the user role that is logged in are grayed out.

NDFC Network Admin

A user with the NDFC Network Admin role can perform all the operations in SAN Controller.

From Cisco Nexus Dashboard Fabric Controller Release 12.1.1e, a user with this role can perform all operations for MSD fabrics in Networks and VRFs.

You can freeze a particular fabric or all fabrics in SAN Controller if you are a user with the NDFC Network Admin role.

Note

Make sure that the switch user role for discovery or add switches or LAN credentials for NDFC must have the network-admin role.

NDFC Device Upgrade Admin

A user with the NDFC Device Upgrade Admin role can perform operations only in Image Management window.

See the Image Management section for more information.

NDFC Access Admin

A user with the NDFC Access Admin role can perform operations only in Interface Manager window for all fabrics.

An NDFC access admin can perform the following actions:

Add, edit, delete and deploy layer 2 port channels, and vPC.
Edit host vPC, and ethernet interfaces.
Save, preview, and deploy from management interfaces.
Edit interfaces for LAN classic, and IPFM fabrics.

Apart from nve, management, tunnel, subinterface, SVI, interface grouping, and loopback interfaces

However, a user with the SAN Controller access admin role can’t perform the following actions:

Cannot edit layer 3 port channels, ST FEX, AA FEX, loopback interfaces, nve interfaces, and subinterfaces.
Cannot edit member interfaces and port channels of Layer 3, ST FEX, AA FEX.
Cannot edit interfaces with policy associated from underlay and link for easy fabrics.
Cannot edit peer link port channel.
Cannot edit management interface.
Cannot edit tunnel.

Note

The icons and buttons are grayed out for this role when the fabric or SAN Controller is in deployment-freeze mode.

NDFC Network Stager

A user with the NDFC Network Stager role can make configuration changes on SAN Controller. A user with the NDFC Network Admin role can deploy these changes later. A network stager can perform the following actions:

Edit interface configurations
View or edit policies
Create interfaces
Change fabric settings
Edit or create templates

However, a network stager cannot perform the following actions:

Cannot make any configuration deployments to switches.
Cannot perform deployment-related actions from the SAN Controller Web UI or the REST APIs.
Cannot access the administration options like licensing, creating more users, and so on.
Cannot move switches in and out of maintenance mode.
Cannot move fabrics in and out of deployment-freeze mode.
Cannot install patches.
Cannot upgrade switches.
Cannot create or delete fabrics.
Cannot import or delete switches.

NDFC Network Operator

A network operator can view fabric builder, fabric settings, preview configurations, policies, and templates. However, a network operator cannot perform the following actions:

Cannot change expected configurations of any switch within any fabric.
Cannot deploy any configurations to switches.
Cannot access the administration options like licensing, creating more users, and so on.

The difference between a network operator and a network stager is that, as a network stager you can only define intent for existing fabrics, but cannot deploy those configurations.

Only a network admin can deploy the changes and edits that are staged by a user with the network stager role.

Choosing Default Authentication Domain

By default login screen on Nexus Dashboard chooses the local domain for authentication. You can change domain at login time by choosing available domains from drop-down list.

Nexus Dashboard supports local and remote authentication. The remote authentication providers for Nexus Dashboard include RADIUS, and TACACS. For more information on authentication support, refer https://www.cisco.com/c/en/us/td/docs/dcn/nd/2x/user-guide/cisco-nexus-dashboard-user-guide-211.pdf.

The following table describes RBAC comparison between DCNM and NDFC access:


DCNM 11.5(x)	NDFC 12.0.x and 12.1.x
User has a single role. All APIs and resources are accessed with this single role.	User can have a different role in different Nexus Dashboard for security domains. Security domain contains single Nexus Dashboard, and each Nexus Dashboard contains single NDFC Fabric.
A single role is associated with the user by disabling or restricting the access to options in DCNM.	A single role displays only privileged resources on the selected page and restricted access are grayed out based on security domain associated with selected resource on further options on NDFC.
DCNM AV Pair format with shells, roles, and optional access constraints.	Nexus Dashboard AV Pair format with shells, domains.
Supported roles based on deployment type LAN, SAN, or PMN.	Supported roles such as network-admin, network-operator, device-upg-admin, network-stager, access-admin are in NDFC. Support for legacy roles for backward compatibility. Nexus Dashboard admin role as network-admin of DCNM.

The following table describes DCNM 11.5(x) AV Pair format:


Cisco DCNM Role	RADIUS Cisco-AV-Pair Value	TACACS+ Shell Cisco-AV-Pair Value
Network-Operator	shell:roles = "network-operator" dcnm-access="group1 group2 group5"	cisco-av-pair=shell:roles="network-operator" dcnm-access="group1 group2 group5"
Network-Admin	shell:roles = "network-admin" dcnm-access="group1group2 group5"	cisco-av-pair=shell:roles="network-admin" dcnm-access="group1 group2 group5"

The following table describes NDFC 12.x AV Pair format:


User Role	AVPair Value
NDFC Access Admin	Access-admin
NDFC Device Upgrade Admin	Device-upg-admin
NDFC Network Admin	Network-admin
NDFC Network Operator	Network-operator
NDFC Network Stager	Network-stager

The AV pair string format differs when configuring a read/write role, read-only role, or a combination of read/write and read-only roles for a specific user. A typical string includes the domain, followed by the read-write roles separated from the read-only roles using the slash (/) character; individual roles are separated by the pipe (|) character:

shell:domains=<domain>/<writeRole1>|<writeRole2>/<readRole1>|<readRole2>

Nexus Dashboard Security Domains

Access control information about a user login contains authentication data like user ID, password, and so on. Based on the authorization data, you can access resources accordingly. Admins in Cisco Nexus Dashboard can create security domains and group various resource types, resource instance, and map them into a security domain. The admins define an AV-pair for each user, which defines the access privileges for users to different resources in Cisco Nexus Dashboard. When you create a fabric, a site is created in Nexus Dashboard with the same fabric name. You can create and view these sites from Nexus Dashboard > Sites.

The SAN Controller REST APIs use this information to perform any action by checking the authorization.

Note

When accessing REST APIs, you can verify passed payload in JSON format. Ensure that the payload is an appropriate JSON format.

When you upgrade from SAN Controller Release 11.x, each fabric is mapped to an autogenerated site of the same name. All these sites are mapped into the all security domain in Nexus Dashboard.

All resources are placed in all domain before they are assigned or mapped to other domains. The all security domain does not include all the available security domains in Nexus Dashboard.

AV-Pairs

A group of security domains along with read and write roles for each domain are specified using AV-pairs. Administrators define AV-pair for each user. The AV-pair defines the access privileges to users across various resources in Nexus Dashboard.

The AV-pair format is as follows:

"avpair": "shell:domains=security-domain/write-role-1|write-role-2,security-domain/write-role-1|write-role2/read-role-1|read-role-2"

For example: "avpair":

"shell:domains=all/network-admin/app-user|network-operator". "all/admin/" makes user super-user and it's best to avoid examples
                                 with all/admin/"

The write role is inclusive of read role as well. Hence, all/network-admin/ and all/network-admin/network-admin are the same.

Note

From SAN Controller Release 12.0.1a supports the existing AV-pair format that you created in SAN Controller Release 11.x. However, if you are creating a new AV-pair, use the format that is mentioned above. Ensure that the shell: domains must not have any spaces.

Specifying Cisco NX-OS User Roles and SNMPv3 Parameters on AAA Servers

You can use the VSA cisco-AV-pair on AAA servers to specify user role mapping for the Cisco NX-OS device using this format:

shell:roles="roleA roleB …"

If you do not specify the role option in the cisco-AV-pair attribute, the default user role is network-operator.

You can also specify your SNMPv3 authentication and Privacy protocol attributes as follows:

shell:roles="roleA roleB..." snmpv3:auth=SHA priv=AES-128

The SNMPv3 authentication protocol options are SHA and MD5. The Privacy protocol options are AES-128 and DES. If you do not specify these options in the cisco-AV-pair attribute, MD5 and DES are the default authentication protocols.
