- Oracle 12c Enterprise Edition (Conventional)—(Nonpluggable installation)

Note

Cisco DCNM Release 10.4(2) does not support Oracle 12c pluggable database version installation.

- Oracle 12c RAC (nonpluggable installation)

Note

The Cisco DCNM database size is not limited, and increases according to the number of nodes and ports that the DCNM manages with Performance Manager Collections enabled. You cannot restrict the database size. If you choose Oracle database, we recommend that you use Oracle SE or Enterprise edition, instead of Oracle XE due to table space limitations.

Note

Customers are responsible for all the support associated with the Oracle databases, including maintenance, troubleshooting, and recovery. We recommend that customers perform regular database backups, either daily or weekly, to ensure that all the data is preserved.

Cisco DCNM Release 10.4(2) supports ISO installation on bare-metal server (no hypervisor) on the following server platform:

- Cisco UCS C240M4 12G / 100G 4-CPU Cores with Cisco hardware RAID Controller [UCSC-MRAID12G-1GB/2GB] for RAID operation.

Cisco DCNM Release 10.4(2) supports the running of the Cisco DCNM Server on the following hypervisors:

- VMware ESXi 6.0

- VMware ESXi 6.5

- VMware ESXi 6.7

- VMware ESXi 6.7 U1

- VMware vCenter 6.0

- VMware vCenter 6.5

- VMware vCenter 6.7

- VMware vCenter 6.7 U1

Note

- vCenter server is mandatory to deploy the Cisco DCNM OVA Installer.

- When you log into the VMware vSphere Web Client, the Adobe Shockwave Flash crashes with the latest Google Chrome 62.0.3202.62 (64-bit), Mozilla Firefox 56.0.1 (64-bit) and Internet Explorer 8.0.7601.17514. Hence you cannot install Cisco DCNM on VMware ESX using VMware vSphere Web Client. This is a known issue with Adobe Shockwave Flash version 27.0.0.159.

Cisco DCNM Server resources for various installers are summarized in the following table:

Server Resources for LAN or Programmable Fabric and SAN

LAN: 25 Switches and up to 1000 Ports

Note

- If there are multiple devices in the SNMP unreachable state, or if the Elasticsearch is running, Cisco DCNM (with 12GB memory) may run out of memory. This might happen when you use the Temperature monitoring or the Endpoint Locator features since both applications use Elasticsearch. In this case, you need to add an additional 12 GB memory.

- Although it is not mandatory, we recommend that you register the server system with Domain Name Service (DNS) servers.

Client Requirements

Cisco DCNM SAN desktop client and Cisco Device Manager support Windows 7, Windows 2008, Windows 2012, Windows 10, and Red Hat Linux. The following table lists the minimum hardware requirements for these client systems.

Chapter 3. Guidelines and Limitations

This section lists guidelines and limitations that are related to Cisco DCNM 10.4(2)11.0(1).

- When configuring LDAP for remote AAA, the role assignments are case-sensitive.

- For deployments that require PIM border leaf and multi-site, use Cisco DCNM 10.4(2) or later. vPC and PIM Border leaf cannot coexist in the same fabric. If IP for Media (IPFM) vPC is required, use Cisco DCNM 10.3(2).

- Though deletion of the IP for Media (IPFM) hosts is possible in the DCNM for Media Controller solution, it is recommended that you should use this option with extreme caution, understanding that manual effort is needed to bring the solution back in sync.

- The Cisco non-blocking multicast (NBM) crashes on Cisco Nexus 9000 Series switch that runs NX-OS Release 7.0(3)F3(1). This is a known issue with Cisco Nexus 9000 Series switch that runs NX-OS Release 7.0(3)F3(1). The cleanFlow API might be used for cleaning the stale flows in Cisco DCNM, and that may trigger the issue with Nexus 9000 Series switch that runs NX-OS Release 7.0(3)F3(1).

- The icons or fonts on Cisco DCNM GUI may not appear correctly on Microsoft Windows 10 browsers. This problem can occur if your Windows 10 is set to block untrusted fonts or some security or mitigation options. Microsoft's Internet Explorer Browser Support team has provided with the following steps to address this issue.

- You need to configure the Allow Font Downloads Internet Explorer Setting on the Internet Zone and Restricted Sites Zone (enabled by default). Perform the following steps:

1. Search for Group Policy Editor in Control Panel.

2. Choose Computer Configuration > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Security Page > Internet Zone > Allow Font Downloads.

3. Double click and choose the Enabled radio button.

4. Click OK.

5. Choose Computer Configuration > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Security Page > Restricted Sites Zone > Allow Font Downloads.

6. Double click and choose the Enabled radio button.

7. Click OK.

8. Restart the computer so that the new setting takes effect.

- The Cisco DCNM Virtual Machine Manager integration does not display in topology when the PKCS12 certificate is used. The REST API call to the Elasticsearch fails, and hence the Compute visualization feature does not work. This is because Elasticsearch uses the same SSL, and when you create a new self-signed SSL, you have to maintain the same version with Elasticsearch as well. Therefore the issue is with creating a self-signed SSL and then having the old one at /usr/elasticsearch/fmserver.jks. To address this issue, use JKS keystore format and do not use pkcs12 certificate. Make sure that the same JKS file is copied to both JBoss and Elasticsearch locations.

- POAP Dynamic Breakout—Beginning with Cisco NX-OS Release 7.0(3)I4(1), POAP dynamically breaks out ports in an effort to detect a DHCP server behind one of the broken-out ports. Previously, the DHCP server used for POAP had to be directly connected to a normal cable because breakout cables were not supported. POAP determines which breakout map (for example, 10gx4, 50gx2, 25gx4, or 10gx2) brings up the link that is connected to the DHCP server. If breakout is not supported on any of the ports, POAP skips the dynamic breakout process. After the breakout loop completes, POAP proceeds with the DHCP discovery phase as normal.

Cisco DCNM leverages dynamic breakout to simplify fabric setup by retaining successful breakout configuration. Since dynamic breakout requires the other side of the link to be active, there are circumstances where you need to manually breakout interfaces, or may notice breakout in places which are not desired. In those situations, the user should adjust the ports on the Interfaces page before performing Save and Deploy in the Fabric Builder.

- If you want to perform an In-Service Software Upgrade (ISSU), you need to configure both IPv4 and IPv6 addresses on the switch.

- To support IPv6 addressing in Nexus 9000 Leaf template, the custom template needs to be configured with the IPv6 address field and the IPv6 gateway without IPv4 fields. The BUM Multicast Replication fields need to be added to specify correct RP Group and anycast IP address.

- Depending on how a switch handles the cdp enable CLI command (enabled or disabled by default), sometimes Cisco DCNM shows this as config difference, although the Save and Deploy operation is performed to correct it. This depends on the default behavior of the switch image (that is, whether the "show running-config" shows the CLI or not). To address this issue, the respective policy_template applied on the interfaces can be updated so that this CLI is ignored during the compliance check.

- When you edit a template in Cisco DCNM 10.4(2) while it is in use, the template changes are saved on the DCNM Web UI but not on the disk. If this setup is upgraded to Cisco DCNM 11.0(1), the template changes made in 10.4(2) are not retained since backup reads content from disk. To address this issue, ensure that the content on DCNM Web UI matches with the content on disk. If it does not match, you must manually edit these templates in 10.4(2) on disk before taking the backup of the content.

- During the installation if EPL eth2 adapter is used when eth0 and eth1 adapters are configured, the virtual machine needs to come up first. If the virtual machine does not come up before eth2 adapter is configured, the eth1 adapter will not come up, because of the incorrect mac-address assignment by installer.

- You should create a free-form configuration on all the white box switches that are managed by Cisco DCNM as shown below, and deploy them on all the switches before the final Save and Deploy operation.

line console
speed 115200
stopbits 2

This is only applicable to the Cisco DCNM LAN Fabric mode.

- On Microsoft Windows 2016 Standard server, you need to run the Cisco DCNM installation EXE file as as administrator. Cisco DCNM installation will not start on Microsoft Windows 2016 Standard server unless you set the EXE file as an administrator. To start the installation EXE file, you can right-click on the EXE file, and choose "Run as administrator."

- When the NX-OS Virtual Switches are cloned, they might use the same serial number. Since Cisco DCNM will discover them using the same serial number, the device discovery operation will fail.

- You must undeploy everything before border provisioning. However, Cisco DCNM allows you to change the roles from Leaf to BorderLeaf and Leaf to BorderGateway, or vice versa. Cisco DCNM also allows you to enable VRF-Lite and Multisite Domains with active deployments. You must ensure that the Border provisioning is enabled on the switch before deployment.

- Cisco DCNM allows you to view and purge the various events between the Host and Flow. The Events are recorded on Media Controller > Events. When you click Purge to remove the old or unwanted events, the DCNM server restarts, by default a maximum of 5000 event entries are retained for 6 hours..

- Though deletion of PMN hosts is possible in the Cisco DCNM for Media Controller solution, it is recommended that you should use this option with extreme caution, understanding that manual effort is needed to bring the solution back in sync.

- On the border leaf switch, ethernet interfaces are configured as sender and receiver WAN interfaces to transport multicast traffic between the switch and remote hosts. PIM policies are enabled on the sender and receiver WAN interfaces.

Chapter 4. New Features and Enhancements

Cisco Data Center Network Manager (DCNM), Release 10.4(2) includes the new features, enhancements, and hardware support that are described in the following section:

- New Features and Enhancements in Cisco DCNM, Release 10.4(2)

New Features and Enhancements in Cisco DCNM, Release 10.4(2)

This section includes information about the new features, enhancements, and hardware support for Cisco DCNM, Release 10.4(2).

PIM Router

The PIM Router feature introduced in the 10.4(2) release enables multicast traffic flow between DCNM managed and external fabrics. This is for IP Fabric for Media and therefore this feature supports the exchange of media flows between an DCNM managed IP fabric for media and external systems. A border leaf switch facilitates multicast traffic between the fabric’s hosts and remote hosts.

For more information about this feature, see the DCNM Web Client Online Help.

Inline Upgrade

The Standalone Inline Upgrade and DCNM Native HA Inline Upgrade methods have been introduced as alternatives to the existing upgrade methods for OVA and ISO. Users can now upgrade with a fewer number of steps for these upgrade methods. For more information about the inline upgrade methods, see the Standalone Inline Upgrade for OVA/ISO section of the Cisco DCNM Installation Guide, Release 10.4(2).

LAN Fabric Provisioning Enhancements

This release supports multi-select, separation of VRF and Network deployment, and L2 and L3 extension via Border devices. For more information about this feature, see the Cisco DCNM Web Client Online Help.

NFM to DCNM Overlay Migration

Cisco Nexus Fabric Manager (NFM) provides a simple point-and-click approach to build and manage both the underlay spine-leaf topology and the VXLAN overlay. Since it is fully fabric aware, it understands how the fabric should operate and can autonomously configure and maintain fabric health throughout its lifecycle. You can migrate your existing Cisco NFM deployments to Cisco DCNM to gain additional capabilities.

Cisco DCNM 10.4(2) provides a migration assistant to read and migrate the NFM-generated configurations of a switch into the LAN Fabric Provisioning functions of Cisco DCNM. For more information about this feature, see the Cisco DCNM Web Client Online Help.

Network Operator View for Config Archive

The Switch dashboard has a new tab that shows archives for the selected device.

Preview Features

In Cisco DCNM Release 10.4(2), the following two features have been introduced for preview for LAN deployments. The idea behind the preview features is to allow customers to provide some early feedback that can then be incorporated into the General Availability (GA) release of these features. The preview features have not been qualified for any scaled environments.

- Compute Visibility with VMware Virtual Center (vCenter)

- Environmental Metrics visibility via streaming telemetry

These features are only available in the OVA form factor for DCNM 10.4.2. The installer options in which these features are supported are:

- VXLAN Fabric

- LAN, SAN, Auto-Config

For more information about this feature, see the Cisco DCNM Web Client Online Help.

Chapter 8. Caveats

Caveats describe unexpected behavior in a product. The Open Caveats section lists open caveats that apply to the current release and may apply to previous releases. A caveat that is open for a prior release and is still unresolved applies to all future releases until it is resolved.

To view the details of the software bugs pertaining to your product, perform the following task:

- Click the Caveat ID/Bug ID number in the table.

The corresponding Bug Search Tool window is displayed with details of the Caveat ID/Bug ID.

The Bug Search Tool (BST), which is the online successor to the Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting. The BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data, such as bug details, product, and version. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.

To view the details of a caveat whose ID you do not have, perform the following procedure:

1. Access the BST using your Cisco user ID and password at:
https://tools.cisco.com/bugsearch/

2. In the Bug Search window that is displayed, enter the necessary information in the corresponding fields.

For more information about how to use the Cisco Bug Search Tool effectively, including how to set email alerts for bugs and to save bugs and searches, see Bug Search Tool Help & FAQ.

This chapter lists the Open and Resolved Caveats in Cisco DCNM, and contains the following section:
