Introduction

Cisco Prime DCNM combines the management of Ethernet and storage networks into a single dashboard to help network and storage administrators manage and troubleshoot health and performance across the following product families that run Cisco NX-OS software. DCNM 7.0 specifically addresses the deployment of Cisco Dynamic Fabric Automation (DFA). The following devices are supported for DFA deployments:

  • Cisco Nexus 5000, 6000, and 7000 Series Switches
  • Cisco Nexus 2000 Series Fabric Extenders

System Requirements

This section lists the tested and supported hardware and software specifications for Cisco DCNM server and client architecture. The application has been tested in English locales only.

This section includes the following topics:

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 7.0(1) 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 7.0(x) supports running the Cisco DCNM server on the following hypervisor:

Deployment Best Practices

Observe the following guidelines when deploying Cisco DCNM:

  • Database

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:

SQL> GRANT CONNECT,RESOURCE,UNLIMITED TABLESPACE TO username IDENTIFIED by password;
Grant succeeded.
SQL> select username,password from dba_users where username=’username’;
SQL> ALTER PROFILE DEFAULT LIMIT
2 FAILED_LOG_ATTEMPTS UNLIMITED
3 PASSWORD_LIFE_TIME UNLIMITED;
Profile altered.
SQL> EXIT
  • Network Time Protocol

We recommend that the Cisco DCNM server run the Network Time Protocol (NTP) to synchronize its clock with those of the managed devices.

  • General Guidelines

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).

Installation Notes

The following installation notes apply to Cisco DCNM Release 7.0:

  • The Cisco DCNM virtual appliance includes the Cisco DCNM server and clients, Device Manager, PostgreSQL, Cisco XCP, OpenLDAP, RabbitMQ, DHCPD, all of which are installed on a 64-bit CentOS.
  • Upgrade support is not available from any previous versions of DCNM.

For information about installing Cisco DCNM Release 7.(x), see the Cisco DCNM Installation Guide. You can find this publication on Cisco.com at this location:

http://www.cisco.com/en/US/products/ps9369/tsd_products_support_series_home.html

New Features and Enhancements in Cisco DCNM Release 7.0

DCNM 7.0 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

  • DCNM 7.0 release provides DCNM as an Open Virtual Applianc (OVA), that can be deployed on VMware vSphere infrastructure. DCNM 7.0 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:

Switch name

Real-time End Host Virtual/Physical Machine association (Tenant-awareness)

Org/Partition defined in LDAP.

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:

  • Network database

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.

  • Message broker

Internal or external Advanced Message Queuing Protocol (AMQP) server to monitor any creation/update/deletion of auto-configuration elements.

  • IP address management

Local DHCPD packaged by default where user can define DHCP scopes to be used by DHCP requests coming from the Leaf.

  • Extensible messaging

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

Web Services API

DCNM Provides REST based API for the following operations:

  • Authentication
  • Auto-Config
  • POAP
  • Cable Plan

For more details on actual usage guidelines and request/response samples, please refer to the Web Services API Guide.

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.

Caveats

This section includes the following topics:

Open Caveats—Cisco DCNM Release 7.0

This section lists caveats that apply to both Cisco DCNM-LAN and Cisco DCNM-SAN.

  • CSCum13457

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.

  • CSCuf73759

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.

  • CSCul88797

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.

  • CSCul07068

Symptom : When a switch is discovered, the mgmt0 interface is not shown in the Interface listing page for the switch.

Conditions : Always.

Workaround : There is no workaround.

  • CSCum62685

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

  • CSCum80871

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.

  • CSCum55604
