The DCNM Licensed
Devices feature allows you to control which physical devices you can manage
with licensed DCNM features. The feature maintains a list of licensed devices.
If a device is on this list, you can manage licensed Cisco DCNM features on the
You can add as many
devices to licenses as your licenses support. For example, if you install two
LAN Enterprise licenses that each support 5 devices, you can add a total of 10
devices to the list of licensed devices.
You can also remove
devices from the list of licensed devices and replace them with other devices.
When you try to use a
Cisco DCNM licensed feature to configure a device that you have not added to
the list of licensed devices, the Cisco DCNM client does not allow you to use
the feature to configure the unlicensed device.
Cisco DCNM Release 10.x is packaged with a time-based default evaluation license upon install. An Advanced Feature Trial License exists on the server after the initial installation. On the Cisco DCNM Web Client, a license filename with text of “30DayTrialLicense” is added in Administration > DCNM Server > License page. After 30 days of trial, click on Assign All or Unassign All to change all the license from evaluation license to permanent licenses on the Cisco DCNM Web Client at Administration > DCNM Server > License > License Assignments.
This provides 500 SAN and 500 advanced feature licenses without having to download or install a single file. This license will work for any licensable switch and expires after 30 days. You must use the MAC address of the DCNM server to fetch an evaluation license or a permanent license from www.cisco.com.
The license costs for Cisco DCNM are determined by the switch platform type and by the number of units within each platform. The advanced feature licenses are available for the following switch platforms: Cisco Nexus 7000, Nexus 5000, Nexus 3000, MDS 9100, MDS 9200, MDS 9300, MDS 9500, and MDS 9700 Series switches. Each platform has an individual price that is based on whether it is a LAN versus SAN switch and modular versus a fixed chassis. The advanced features for Cisco Nexus 1000V and Cisco Nexus 4000 Series switches are part of the image at no cost. In addition, Cisco DCNM has a many features that are enabled for free as part of the image. These features that are free are referred to as essential features. The features are split between SAN and LAN platforms (hardware support and Cisco NX-OS features) and application-specific features such as VMware path analytics [vCenter integration], performance trending, event forwarding, and so on.
However, the biggest
value of Cisco DCNM is its license structure. If you have purchased the Cisco
DCNM advanced feature license for any Cisco Nexus or MDS switches, that license
stays valid for the lifetime of the platform at Cisco. For example, if you
replace an older switch with a new generation switch of the same platform (that
is, MDS 9506 with MDS 9513) the license can be reassigned. Cisco DCNM advanced
licenses are also available as part of Cisco Nexus 7000 and Nexus 5000 software
Cisco DCNM also
supports older Fabric Manager (FM) licenses (SAN only) that have been installed
on the switch. These licenses provide high availability (HA) with up to ten
management servers that manage a single fabric in parallel. However, Fabric
Manager licenses are only valid for the lifetime of the switch inside the data
center and expire when the switch is decommissioned from the data center. You
can still order FM licenses as spares if you prefer the HA capability.
Services contract SKUs
(CON-SAU) are required for Cisco TAC support for upgrades from one version of
Cisco DCNM to another. The upgrade path also includes the Fabric Manager to
DCNM upgrade (from FMS 5.0 to DCNM 5.2).
If you would like to evaluate Cisco DCNM in your own environment, Cisco makes the advanced licenses available for 60 days which can be extended by another 60 days if required (EVAL/DEMO site). This demo license is limited to 20 units per platform. Go to www.cisco.com/go/licensing to obtain demo/evaluation licenses.
Starting from release 10, Cisco DCNM consists of three components: Device Manager, Converged LAN and SAN web client and SAN Java Client (DCNM for SAN).
