Cisco Virtual Network Management Center 2.1 Release Notes
June 3, 2013
This document describes the features, bugs, and limitations for the Cisco Virtual Network Management Center (VNMC) 2.1 release.
Use this document in combination with the documents listed in the "Related Documentation" section.
This document includes the following sections:
VNMC is a virtual appliance, based on Red Hat Enterprise Linux, that provides centralized device and security policy management of Cisco virtual services. Designed for multiple-tenant operation, VNMC provides seamless, scalable, and automation-centric management for virtualized data center and cloud environments. With both a built-in UI and an XML API, VNMC enables centralized management of Cisco virtual services by an administrator or through an API.
VNMC is built on an information model-driven architecture in which each managed device is represented by its subcomponents (or objects), which are parametrically defined. This model-centric approach enables VNMC to provide a secure, multiple-tenant virtualized infrastructure with Cisco Adaptive Security Appliance 1000V (ASA 1000V) and Cisco Virtual Security Gateway (VSG) virtual services.
Table 1 describes the primary features of VNMC.
Table 2 identifies VNMC system requirements.

To disable default Adobe flash players in Chrome:
Step 1 In the Chrome URL field, enter chrome://plugins.
Step 2 Click Details.
Step 3 Locate the Flash player plugins, and disable each one.
Step 4 Download and install Adobe Flash player version 11.3.300.265.
Step 5 Close and reopen Chrome before logging into VNMC 2.1.
Performance and Scalability
Table 3 lists the performance and scalability data for VNMC 2.1.
NTP Requirements for Deploying and Operating VNMC
You must do the following for proper VNMC operation with VMware, ASA 1000V, VSG, and VSM:
1. Before you deploy the VNMC OVA, configure Network Time Protocol (NTP) servers on all ESXi servers that run VNMC, ASA 1000V, VSG, and VSM to ensure proper operation.
For information, see Configuring Network Time Protocol (NTP) on ESX/ESXi 4.1 and ESXi 5.0 hosts using the vSphere Client at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2012069.
2. Before you perform any operation on VNMC after you deploy the OVA, configure NTP servers for VNMC, ASA 1000V, VSG, and VSM. If you do not do so, ASA 1000Vs, VSGs, and VSMs will not be able to register with VNMC. See Configuring NTP.
Before you perform any operation in VNMC, configure NTP on ASA 1000V, VSG, and VSM. If you do not do so, ASA 1000Vs, VSGs, and VSMs will not be able to register with VNMC.
To configure NTP in VNMC, ASA 1000V, VSG, and VSM:
Configuring NTP in VSM
To configure NTP, enter the following CLI command from the VSM console:ntp server x.x.x.x
where x.x.x.x is the NTP server IP address.
Configuring NTP in VSG
To configure NTP, enter the following CLI command from the VSG console:ntp server x.x.x.x
where x.x.x.x is the NTP server IP address.
Note The ntp server command will not be available in the VSG console if you have installed the VNMC policy agent. To configure NTP in VSG, you must uninstall the VNMC policy agent.
Configuring NTP in ASA 1000V
Before you install ASA 1000V in VNMC, ensure that you have configured NTP on all ESXi servers that run ASA 1000V. For information, see Configuring Network Time Protocol (NTP) on ESX/ESXi 4.1 and ESXi 5.0 hosts using the vSphere Client at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2012069.
After installation, ASA 1000V receives the Real Time Clock (RTC) value from the VMware ESXi host.
Configuring NTP in VNMC
To synchronize VNMC with the NTP Server:
Step 1 In your browser, enter https://vnmc-ip where vnmc-ip is the VNMC IP address.
Step 2 If you receive a certificate warning, choose to continue to the VNMC login window.
Step 3 In the VNMC login window, enter the username admin and the admin user password.
Step 4 From the VNMC GUI, to set the time zone:
a. Choose Administration > VNMC Profile > root > VNMC Profile > default.
b. In the General tab, select the time zone.
c. Click Save.
Step 5 From the VNMC GUI, to add an external NTP server as time source:
a. Choose Administration > VNMC Profile > root > VNMC Profile > default.
b. In the Policy tab, select Add NTP Server.
c. Enter the hostname or IP address and click OK.
d. Click Save.
Caution We recommend that you do not set the time zone after you add the NTP server.
New Features in VNMC 2.1
The following sections describe the new features introduced in the VNMC 2.1 release.
For more information about these features, see the VNMC documentation, available on cisco.com at http://www.cisco.com/en/US/products/ps11213/tsd_products_support_series_home.html.
Microsoft Hyper-V Support
VNMC can be installed on the VMWare Provisory and the Microsoft Hyper-V Hypervisor. The following are some of the VNMC features that are not supported when VNMC is installed on Hyper-V Hypervisor.
When you are adding a rule to create the ACL policy:
•The option to match any one rule is disabled. The only available option is to match all the rules.
•The service condition is disabled.
•When you are setting source or destination conditions, the VM attribute type is not supported.
When you are adding an object group:
•When the attribute type is Network, the attribute name Service is not supported.
•The VM attribute type is not supported.
When you are working with vZones, the option to match any one rule is disabled. The vZone must match all the conditions.
You can create a clone for an organization, policy, or policy set at a VNMC destination of your choice. The hierarchy of an organization's clone and the names of the elements in it cannot be changed. Once created, a clone cannot be renamed or moved to another location.
You can search for instances of organizations in VNMC using the search tab in the policy management, tenant management, and resource management tabs.
When you enter an organization name as a pattern or a regular expression in the search text box, the search result is displayed. From the search result, you can expand the organization's hierarchy and launch devices and polices in that organization.
Condition Match Criterion in vZone
You can now choose a condition match criterion when you add a vZone. This option enables you to choose all conditions or any one condition to be applied on the vZone.
Service Attribute in Object Group
You can group different types of objects within the same field; for example, you can group port and protocols. The service attribute in the ACL rule enables you to configure protocol and destination port in a single condition.
The following topics describe the limitations in VNMC 2.1:
VNMC 2.1 SSH service has multiple vulnerabilities. For more information, see OpenSSH Security at http://www.openssh.com/security.html.
VNMC VM Manager and VMware vCenter Server Connections
VNMC VM Manager automatically connects to the VMware vCenter server on HTTP port 80. A vCenter extension file is required to establish a connection between VM Manager and vCenter. The extension file is exported from VNMC and linked on the VM Managers tab. You install it as a plugin on all vCenter servers to which you want to connect.
For more information on installing and registering the vCenter extension file, see the Cisco Virtual Network Management Center 2.1 GUI Configuration Guide.
Upgrading vCenter to a New Version
If you upgrade vCenter to a new version and use the same IP address, vCenter attributes are not updated in VNMC. For example, the vCenter attributes for VMs and hosts on the upgraded vCenter are not updated.
To resolve this issue, add the vCenter to VNMC again by choosing Resource Management > Resources > Virtual Machines > VM Managers and clicking Add VM Manager.
Characters in Names Retrieved from vCenter
If you choose Resource Management > Resources > Virtual Machines, the following characters are not allowed in names that are retrieved from vCenter:
" ' ^ & ` < > ? = \ "
If a name that is retrieved from vCenter contains any of these characters, VNMC does not recognize the characters.
Names that can be affected include:
•VM DNS name
•VM parent application name
•VM resource pool name
•Hypervisor cluster name
As a result of this behavior, VNMC attribute names do not display correctly in the UI and might be evaluated differently when these attributes are used in policy conditions.
Value Displayed in Parent App or Resource Pool Field
The VM Properties pane displays Parent App and Resource Pool fields, but only one field contains a value at any time. For example, if the parent application name is displayed, the resource pool name is not displayed. This situation occurs because a VM can be part of a parent application or part of a resource pool, but not both simultaneously.
You can view the VM Properties pane by choosing Resource Management > Resources > Virtual Machines > VM Managers > vm-manager > host-ip-address > vm where:
•vm-manager is a vCenter.
•host-ip-address is the ESXi host IP address in dotted-decimal format (x.x.x.x)
•vm is a specific VM.
Searching for Organization Names
If an organization name contains special characters, it will not be searchable.
The open bugs for VNMC are available in the Cisco Bug Toolkit. The Cisco Bug Toolkit enables you to search for a bug by identifier or product and version, and can provide additional details about the bug, such as more information or that the bug has been fixed.
