Using the ANM Plug-In With Virtual Data Centers
This appendix describes how to integrate ANM sever with VMware vCenter Server, which is a third-party product for creating and managing virtual data centers. Using VMware vSphere Client, you can access ANM functionality and manage the ACE real servers that provide load-balancing services for the virtual machines in your virtual data center.
Note When naming ACE objects (such as a real server, virtual server, parameter map, class map, health probe, and so on), enter an alphanumeric string of 1 to 64 characters, which can include the following special characters: underscore (_), hyphen (-), and dot (.). Spaces are not allowed. If you are using ANM with an ACE module or ACE appliance and you configure a named object at the ACE CLI, keep in mind that ANM does not support all of the special characters that the ACE CLI allows you to use when configuring a named object. If you use special characters that ANM does not support, you may not be able to import or manage the ACE using ANM.
This appendix includes the following sections:
This section describes how you can integrate ANM server into a VMware virtual data center environment. This feature enables you to access ANM functionality from within the VMware environment to provision the application delivery services that the ACE real servers provide.
ANM version 3.1and later includes the ANM plug-in for vCenter Server that enables the integration of ANM with the VMware environment as shown in .
Figure 22-1 ANM Integrated With VMware vCenter Server and vSphere Client
From the ANM GUI, you register the ANM plug-in by specifying a VMware vCenter Server and ANM server attributes that enables ANM to communicate with VMware vCenter Server and vSphere Client using HTTPS and default port 443. When the plug-in is registered, the VMware vSphere Client GUI displays the Cisco ACE SLB tab when you select a virtual machine (VM) from the client GUI.
You click on the Cisco ACE SLB tab to log into ANM from the VMware vSphere Client and perform the following tasks:
Define a virtual machine (VM) as a real server on ANM and associate it with an existing ACE virtual context and server farm.
Monitor application traffic flow for virtual machines through the ACE.
Activate and suspend application traffic flows through the ACE for the associated real servers.
Add or delete real servers from the list of servers associated with a VM.
Note In addition to ACE devices, the Cisco ACE SLB tab also displays services on the Content Services Switch (CSS) and real servers on the Cisco Content Switching Module (CSM) devices associated with a virtual machine. For these device types, from the Cisco ACE SLB tab, you can activate or suspend the services or real servers but you cannot add or delete these items.
For information about how ANM maps real servers to VMware virtual machines, see the .
For more information about the Cisco ACE SLB tab, see the
This section describes the components of the Cisco ACE SLB tab that display in vSphere Client when you choose a VM from the VM tree (see ).

For more information about these function buttons, see the following topics:
The prerequisites for integrating ANM with VMware vCenter Server and vSphere Client are as follows:
You must use ANM version 3.1 or later with VMware vSphere 4 or vSphere 5.
You must register the ANM plug-in from within ANM to enable communication between the two applications (see the ).
If you are running VMware vSphere Client on a Windows Server 2003 or 2008 operating system, make sure that the following Internet security options (Internet options & Security setting) are enabled:
– Allow META REFRESH
– Allow scripting of Internet Explorer web browser control
These options are not enabled by default. If they are disabled, the ANM plug-in will not allow you to log in to ANM for security reasons or you may encounter refresh problems with the Cisco ACE SLB tab.
Note We recommend that you have VMware Tools installed on the guest OS of each VM to allow ANM to match a real server with a VM based on the IP address rather than a server name (see the ).
Follow these guidelines and restrictions when integrating ANM with VMware vCenter Server and vSphere Client:
There are no shared logins or trust established between ANM and vCenter Server when you open a session between the two servers.
You can configure both ANM and vCenter Server to use Active Directory for authentication.
From ANM, you must register the ANM plug-in before you can see the Cisco ACE SLB tab from VMware vSphere Client (see the ). When you register the plug-in, the VMware vSphere Client display refreshes and displays the Cisco ACE SLB tab.
ANM supports one registered ANM plug-in instance only, which means that you can register only one plug-in at any given time.
For example, if you register the plug-in from ANM Server A and then register the plug-in from ANM Server B, the following actions occur:
– The ANM Server A plug-in is unregistered.
– Any VMware vSphere Client that was running when the ANM Server B plug-in was registered will continue to display ANM Server A’s information in the Cisco ACE SLB tab. You must restart VMware vSphere Client to access and display ANM Server B’s information.
If you are going to uninstall ANM from the ANM server, make sure that you unregister the ANM plug-in before you uninstall ANM. If you do not unregister the plug-in before the uninstall, from VMware vSphere Client, the plug-in will display as registered but will fail to load.
For information about unregistering the ANM plug-in, see the . For information about uninstalling ANM, see one of the following guides depending on your ANM application:
Note This feature requires the admin role for ANM.
This section describes how to register the ANM plug-in from ANM, which allows you to access ANM ACE real server functionality from VMware vSphere Client. Registering the plug-in provides the client with a URL to access ANM and retrieve the required XML definition file. ANM uses HTTPS for communication with VMware vCenter Server.
You can also unregister the ANM plug-in from ANM.
Note Unregistering the ANM plug-in does not prevent access to the ANM server or remove the Cisco ACE SLB tab from any VMware vSphere Client display that was running when you unregistered the plug-in. You must restart the client to remove the Cisco ACE SLB tab from the display. A VMware vSphere Client restart is also required when you unregister a ANM plug-in from one ANM server and register another plug-in from a second ANM server.
Guidelines and Restrictions
When registering the ANM plug-in, you specify the VMware vCenter Server and ANM server. If you specify the servers using server names rather than IP addresses, the names must be in DNS and must be consistent throughout the network. If the server names reside only in local /etc/host files, then use IP addresses in place otherwise, the ANM server and vCenter Server may not be able to communicate and errors may occur, including the inability to enable the plug-in or the inability for real server mapping (empty tables).
Step 1 From ANM, choose
ANM Management
Virtual Center Plugin Registration.
The VMware Virtual Center PlugIn Registration window appears.
Step 2 Register or unregister the ANM plug-in using the information in .

Table 22-4 ACE Reals Table Fields
Name of real server on the ACE, CSS, CSM, or CSM-S. Although the Cisco ACE SLB tab is primarily used to monitor and manage ACE real servers, you can also monitor, activate, and suspend CSS, CSM, and CSM-S devices from this tab.
The real server name is a link that displays the Real Server Details popup window, which provides operating information about the server (see the ).
IP Address
Real server IP address.
Real server port number.
Admin State
Administrative state of the real server as follows:
In Service
Out Of Service
In Service Standby.
Note For CSM and CSM-S real servers, ANM infers the admin state based on the operational state that it receives through SNMP rather than the CLI, which may result in an admin state display that is not correct. For example, when you change the operational state of a CSM real server from Out of Service to Inservice, the admin state display should also change to In S however, the admin state display may remain set to Out of Service.
Oper State
Operational state of the real server as follows:
ARP Failed—Corresponding VLAN interface is not configured for the real server.
Failed—Server has failed and will not be retried for the amount of time specified by its retry timer.
Inband probe failed—Server has failed the inband Health Probe agent.
Inservice—Server is in use as a destination for server load balancing client connections.
Inservice standby—Server is the backup real server, which remains inactive unless the primary real server fails.
Operation wait—Server is ready to become operational but is waiting for the associated redirect virtual server to be in service.
Out of service—Server is not in use by a server load balancer as a destination for client connections.
Probe failed—Server load-balancing probe to this server has failed. No new connections will be assigned to this server until a probe to this server succeeds.
Probe testing—Server has received a test probe from the server load balancer.
Ready to test—Server has failed and its ret test connections will begin flowing to it soon.
Return code failed—Server has been disabled because it returned an HTTP code that matched a configured value.
Test wait—Server is ready to be tested. This state is applicable only when the server is used for HTTP redirect load balancing.
Testing—Server has failed and has been given another test connection. The success of this connection is not known.
Throttle: DFP— has lowered the weight of the serv no new connections will be assigned to the server until DFP raises its weight.
Throttle: max clients—Server has reached its maximum number of allowed clients.
Throttle: max connections—Server has reached its maximum number of connections and is no longer being given connections.
Unknown—State of the server is not known.
Number of concurrent connections.
Weight assigned to the real server.
Server Farm
Server farm that the real server is associated with.
Name of the Vserver.
ACE, CSS, CSM, or CSM-S on which the real server is configured.

You might enter a trouble ticket, an order ticket, or a user message.
Note Do not enter a password in this field.
Step 5 From the Suspend Real Servers Type drop-down list, choose one of the following:
Graceful —When executed on a primary server, the ACE gracefully shuts down the server with sticky connections as follows:
– Tears down existing non-TCP connections to the server
– Allows current TCP connections to complete
– Allows new sticky connections for existing server connections that match entries in the sticky database
– Load balances all new connections (other than the matching sticky connections mentioned above) to the other servers in the server farm
When executed on a backup real server, the ACE places the backup server in service standby mode.
Note For the CSS, when the device is in the In Service admin state and you perform a graceful suspend operation, ANM saves the last known non-zero service (or real server) weight, and then sets the weight to zero. ANM references the saved weight when performing an Activate operation. If the current weight is zero, and a non-zero weight has been saved for that service (or real server), the Activate operation also sets the weight to the saved value.To allow ANM to save and reset the weight value when gracefully suspending and then activating the CSS, you must have the device configured to permit SNMP traffic. For each device type, see the corresponding configuration guide to configure the device to permit SNMP traffic.When the CSS is in the In Service Standby admin state and you perform a graceful suspend operation, ANM does not set the weight to zero.
Suspend —The ACE resets all non-TCP connections to the server. For TCP connections, existing flows are allowed to complete before the ACE takes the real server out of service. No new connections are allowed. The ACE resets all Secure Sockets Layer (SSL) connections to the real server.
Suspend and Clear Connections —The ACE performs the tasks described for Suspend and clears the existing connections to this server.
Step 6 Do one of the following:
Deploy Now
to suspend the server and to return to the ACE Reals table. The server appears in the table with the status Out Of Service.
Cancel to exit this procedure without suspending the server and to return to the ACE Reals table.
Related Topics
You can modify the weight value assigned to a real server that defines the connection capacity of the server in relation to the other real servers. The ACE uses the weight value that you specify for a server in the weighted round-robin and least-connections load-balancing predictors. Servers with a higher configured weight value have a higher priority with respect to connections than servers with a lower weight. For example, a server with a weight of 5 would receive five connections for every one connection for a server with a weight of 1.
