Java Requirements
Cisco DCNM Server is distributed with Java JRE 1.6.0_31. Cisco DCNM clients should also use Java JRE 1.6.0_31. The DCNM installer installs JRE 1.6.0_31 to the following directory: DCNM_root_directory/java/jre1.6.
Server Requirements
Cisco DCNM Release 7.x supports the following databases:
- Oracle11g Express (XE), Standard, and Enterprise Editions, and Oracle 11g Real Application Clusters (RAC).
For deployment best practices, see the “Deployment Best Practices” section.
Note
Customers are responsible for all support associated with Oracle database, including maintenance, troubleshooting, and recovery. Cisco recommends that customers perform regular database backups, either daily or weekly, to ensure that all data is preserved.
Cisco DCNM Release 7.x supports running the Cisco DCNM server on the following hypervisor:
Table 2 lists the minimum and recommended database server system requirements for running Cisco DCNM and using an external Oracle Database.
DCNM Host Requirements
Table 3 lists the server resource requirements for deploying Cisco DCNM 7.x Virtual Appliance (OVA).
Client Requirements
Cisco DCNM clients support Windows 7, Windows 2008, and Red Hat Linux. Table 4 lists the minimum hardware requirements for these client systems.
Some Cisco DCNM features require a license. Before you can use the licensed features, you must install the Cisco DCNM license. For more information, see the Cisco DCNM OVA Installation Guide, Release 7.x.
Be sure to set the correct time zone value on the client system’s clock (for example, UTC). Otherwise, Cisco DCNM-LAN cannot manage the switch properly.
Browsers
Web browsers that support Adobe Flash 10 are qualified for use with Cisco DCNM. These include Internet Explorer, Firefox, and Safari.
Other Supported Software
Table 5 lists other software supported by Cisco DCNM Release 7.x.

Software Download Site
To download the Cisco DCNM 7.x software, go to http://www.cisco.com/go/dcnm and click Download Software.
Deployment Best Practices
Observe the following guidelines when deploying Cisco DCNM:
– Deploy an Oracle database when managing production or mission critical environments.
– Deploy an Oracle database on a separate server from the Cisco DCNM application server.
– If you plan to use an Oracle 11g database, configure the Oracle database as follows:
Increase the number of sessions and processes to 150 each from the default of 50.
Increase the number of open cursors to 1000 from the default of 300.
– We recommend deploying Oracle11g for mission-critical production environments.
Note The password for the Oracle 11g Express (XE) database expires after 180 days. You must change this setting by using the following steps.
1. Log in to the Oracle database.
2. Enter the commands as shown in this example:
– We recommend that the Cisco DCNM server run the Network Time Protocol (NTP) to synchronize its clock with those of the managed devices.
– Do not deploy Cisco DCNM when network latency is more then 50 ms from the switch management subnet to the Cisco DCNM server and Cisco DCNM database.
– Deploy Cisco DCNM on high-performance tier storage (2 ms to 4 ms response time).

New Features and Enhancements in Cisco DCNM Release 7.0 (1)
DCNM 7.x Open Virtual Appliance (OVA) form factor is not intended to be used to upgrade from DCNM6.x.
This release is specifically targeted with special features related to the DFA architecture. Traditional DCNM6.x LAN/SAN users should use DCNM6.x release train for bug fixes and updates.
Cisco DNCM Release 7.0 includes the new features, enhancements, and hardware support that are described in the following sections:
- OVA Form Factor Packaged with all DFA Components
- Enhanced Visualization and Topology
- POAP
- Auto-Configuration
- DCNM REST API
- Network Services
- Platform-Specific Features
- Supported Cisco Platforms and Software Versions
OVA Form Factor Packaged with all DFA Components
- DCNM 7.x release provides DCNM as an Open Virtual Applianc (OVA), that can be deployed on VMware vSphere infrastructure. DCNM 7.x ships only in the OVA format. The vCenter and ESXi must be version 5.1 or higher for a successful deployment.
- This Virtual Appliance has a pre-installed operating system (CentOS) with pre-installed DCNM Cisco Data Center Network Manager components for Dynamic Fabric Architecture.
- After deployment of the OVA, you can access DCNM Web UI at the configured IP address with credentials: admin/<user provided password>. To login to an ssh session of this deployment you can use the credentials: root/ <user provided password>.
Enhanced Visualization and Topology
A new topology paradigm with color-coded icons and leaf or spine representation with links is designed to give you a quick and useful view of health and functionality of the fabric and end hosts. You can view the topology at Dashboard->Dynamic Fabric Automation.
Following are a few highlights of the new DFA topology:
- Inter Switch Link view and Edge Ports view of Fabric.
- Node and Link status clearly color-coded for easy problem-recognition and reconciliation in large networks.
- Easy Search and Filter options based on:
– Real-time End Host Virtual/Physical Machine association (Tenant-awareness)
POAP
Power On Auto Provisioning (POAP). This is a feature that allows a device to automatically bootup with the desired configuration and images. You can access the configuration at config->Power On Auto Provisioning (POAP).
To facilitate this feature, DCNM has useful GUI and packaged utilities for:
- DHCP Scope definition
- Image and Configuration repository definitions
- Default POAP Templates for Leaf or Spine etc
- Creating required POAP template definition
- Associating a single template to multiple Device instances using a simple UI
- Viewing CLI-previews of deployed templates before they are applied on the device
- Cable plan management from POAP templates or learned Inter-switch links for a given fabric
- Automatically import and management of POAP devices in DCNM, when a device is powered up
Auto-Configuration
Auto-configuration feature enables Automated Network provisioning by integrating and interacting with:
Internal or External LDAP server to which DCNM can read or write profile, organization, partition and network definition These provide data read by the Leaf switches.
Internal or external Advanced Message Queuing Protocol (AMQP) server to monitor any creation/update/deletion of auto-configuration elements.
Local DHCPD packaged by default where user can define DHCP scopes to be used by DHCP requests coming from the Leaf.
Internal or external Extensible Messaging and Presence Protocol (XMPP) server used for multi device communication by DCNM leaves and spines. DCNM can notify leaf switches via XMPP when an auto-configuration event occurs.
- DCNM OVA packages a reference synchronization script for VMware vCD (vCloud Director) integration
- DCNM OVA packages reference script for Cisco Prime Network Registrar (CPNR) integration
Settings for auto-config are available at Admin> Dynamic Fabric Automation (DFA) > Settings
DCNM REST API
DCNM Provides REST based API for the following operations:
For more details on actual usage guidelines and request/response samples, please refer to the Cisco DCNM REST API Guide, Release 7.x.
Network Services
In the Cisco DFA solution, traditional services, such as firewalls and load balancers, are deployed at regular leaf nodes within the spine-leaf topology, and at border leaf nodes. This is unlike more traditional data centers where these services are deployed at the aggregation layer.
Cisco Prime Network Services Controller (Prime NSC) provides the orchestration and automation of network services in Cisco DFA. The Prime NSC supports integration with virtual compute and storage managers such as UCS Director and Openstack Controller to provide end-to-end orchestration and automation for services in Cisco DFA.
A Prime NSC Adapter is bundled within the Cisco DCNM OVA. It performs the following functions:
- Enables DCNM to interoperate with one or more instances of the Prime NSC.
- Provides translation of DCNM language and objects into the Prime NSC language and objects.
- Ensures that the Prime NSC and DCNM are always synchronized.
- Maps the tenants and virtual data centers to the Prime NSC instances responsible for network services.
Platform-Specific Features
Cisco DCNM Release 7.x supports the following platform-specific features:
– Cisco Nexus 3000 buffer usage charts and tabular data for microburst monitoring
Cisco DCNM Release 7.x supports the following platform-specific features:
– Cisco Nexus 7718 18-slot chassis
– Cisco Nexus 7710 10-slot chassis
– Cisco Nexus 7700 Enhanced 48-port 1/10 Gigabit Ethernet SFP+ I/O module (F2 Series)
New Features and Enhancements in Cisco DCNM Release 7.0 (2)
Cisco DNCM Release 7.0.(2) includes the new features, enhancements, and hardware support that are described in the following sections:
- Auto Instantiation of OSPF config profiles behind VPC+
- Service Automation
- DFA template/script support for In-band POAP and Management
- Migration from DCNM 7.0.(1) to DCNM 7.0.(2)
Auto Instantiation of OSPF config profiles behind VPC+
OSPF config behind vPC+ needs different IP addresses for VPC peering, primary switch and secondary switch need different gateway IP Address. In order to support this, a new field Secondary Gateway IP has been added to the Cisco DCNM Web Client at Config>Auto Configuration>network screen, in the Service Configuration Parameters area. Also, you must provide and receive this attribute when you use the DCNM REST API to create, update and get a network.
Service Automation
once the tenant and associated service segments are created, service virtual machines should be instantiated dynamically. In order to support this, in the Cisco DCNM Web Client, a new Network Role mandatory field has been added to the network screen at Config>Auto Configuration. The following values are available for the Network Role.
DFA template/script support for In-band POAP and Management
Updated DFA POAP templates are included with added options including In-band POAP and Management. This option allows POAP, as well as management through the fabric (rather than using an out-of-band management network connected to mgmt0 ports); also XMPP, LDAP, and VPC keep-alive traffic will be sent over a management VLAN.
Supported Cisco Platforms and Software Versions
For information about the software platforms and versions that Cisco DCNM supports, see the Cisco DCNM Release Compatibility Matrix.
Note For compatibility reasons, we recommend that you run the same version (or a later version) of Cisco DCNM as Cisco NX-OS software.

Open Caveats—Cisco DCNM Release 7.0.(1)
This section lists caveats that apply to both Cisco DCNM-LAN and Cisco DCNM-SAN.
Symptom : OVA gets deployed successfully, but the user is unable to login to DCNM Web UI or connect to XMPP. However, the user is able to login to the virtual appliance using SSH terminal.
Conditions : Either the administrative password or hostname entered while deploying the OVA does not conform to the expected format. The format is indicated in the help text shown in the vSphere client screen during deployment.
Workaround : Redeploy the virtual appliance using a proper password that conforms to the description in the help text and a hostname as a fully qualified domain name.
Symptom : The two layer VPC id is not shown on topology pane and links do not display correctly on Topology--> port channel and VPC view.
Conditions : When you discover the two n5k and n1k one by one with hop 0.
Workaround : Discover all the devices (2N5ks and 1 n1k) in one task Or rediscover the 2 uplink N5ks one by one.
Symptom : Connection between Fex and N1k not shown for 2 layer vPC.
Conditions : When using 2 layer vPC setup, the connection between the Fex and N1k is not shown. This is a rare occurrence.
Workaround : Discover the devices in 2 layer vPC serially, one after the other.
Symptom : When a switch is discovered, the mgmt0 interface is not shown in the Interface listing page for the switch.
Workaround : There is no workaround.
Symptom : From POAP definitions, if user edits a definition, goes through all the steps, and finally publishes it, and then tries to go to DFA topology, the screen becomes blank and unresponsive.
The same issue occurs when POAP definition is saved and published, then the user navigates to the DFA screen.
Conditions : When the POAP definition is saved or edited and published and the user goes to DFA topology screen.
Workaround : Doing a browser reload (clicking the reload button on the browser being used) fixes the issue.
Open Caveats—Prime NSC adapter Release 1.0.1
Symptom : Some tenants or networks are missing in NSC after addingVM-mgr for a deployment where VM-mgr has existing tenants or networks.
Conditions : When a VM-mgr is added to a Prime NSC instance where VM-mgr has tenants or networks already present. In some cases, all the tenants or networks are not synced to Prime NSC.
Workaround : Remove the NSC instance using nsc-adapter-mgr nsc remove <ip> comman and then add the NSC instance again using nsc-adapter-mgr nsc add <ip-address> <user-name> <password> command.
Symptom : Upon restarting the NSC adapter, the adapter connections command shows "initializing" state.
Conditions : This happens when one of the NSC instance specified in config.ini file is unreachable due to NSC load.
# /opt/nscadapter/bin/nsc-adapter-mgr adapter connections
Workaround : Using the GUI login, verify the NSC instance reachability. Identify the NSC instance where GUI is not reachable to find out if NSC is unreachable even though pingable. Then follow these steps:
Open Caveats—Cisco DCNM Release 7.0.(2)
This section lists caveats that apply to both Cisco DCNM-LAN and Cisco DCNM-SAN.

Workaround : Discover all the devices (2N5ks and 1 n1k) in one task Or rediscover the 2 uplink N5ks one by one.
Symptom : Connection between Fex and N1k not shown for 2 layer vPC.
Conditions : When using 2 layer vPC setup, the connection between the Fex and N1k is not shown. This is a rare occurrence.
Workaround : Discover the devices in 2 layer vPC serially, one after the other.
Symptom : While generating a POAP, the value of the last column in the array type parameters do not get modified.
Conditions : On opening the pop-up to modify the array type parameters, the last column still displays the default value. All the other columns and the non-array type parameters are updated with the modified values.
Workaround : Do not open the pop-up to modify the array type parameters, you can directly edit the parameters in-line.
Resolved Caveats—Cisco DCNM Release 7.0.(2)
This section lists caveats that apply to both Cisco DCNM-LAN and Cisco DCNM-SAN.
Symptom : From POAP definitions, when you edit a definition, follows all the steps, publishes it, and then tries to view the DFA topology, the screen is blank and unresponsive.
The same issue occurs when POAP definition is saved and published and, then you navigate to the DFA screen.
Conditions : When the POAP definition is saved or edited and published and, then you view the DFA topology screen.
Workaround : You must reload/refresh the browser to resolve this issue.
Symptom : When a switch is discovered, the mgmt0 interface is not shown in the Interface listing page for the switch.
