Hi Tenaro,
Thank you for your question.
At current, we do not setup CUCM in a multi-tenant configuration. Each HCS end-customer gets their own unique CUCM cluster, the same goes for Unity Connection and Unified Presence.
There are a few pieces of software that are unique to HCS
1) HCM - F - This component is used to automate the upgrades of the UC applications, produce bundle-based billing reports from the configuration domain, and also automatically provision/configure the Service Assurance architecture so as you deploy HCS to end customers, the monitoring of those configurations is automatically done for you.
2) Prime Central for HCS Assurance - This component is responsible for provides lots of functionality in regards to monitoring the HCS solution. It aggregates data from CUOM, CUSM, DCNM, and vCenter and can display all the events/errors/alarms that those components are reporting. It also has the ability to normalize these errors and forward them to an exisitng alarm management or ticketing system via SNMP traps. It also includes a reatures like fault correlation (root cause analysis) and service impact analysis which allows you to see what services are affected based on the error information that is being reported.
3) This last item is not really a piece of software, but more an advantage over using UC on UCS as opposed to HCS. Within HCS we allow the over subscription of your UCS resources for some of the smaller OVAs where in UC on UCS you would be required to map a vCPU to an entire core. This allows for much greater denisty. Also, the HCS licensing scheme allows for the SP to pool licenses and transfer between the customers as needed where in UC on UCS, these licenses are bound to customers, once purchased.
To answer your last question, we sell HCS to service providers and partners. Partners may need to have customers bring their own PSTN connectivity or partner with an SP to provide PSTN access, but either way, partners are just as capable of providing this service.
Hope that helps. Thanks again Tenaro!

Hi J,
The process of creating a new customer is not yet fully automated, but we are working on vCenter integration that may eventually automate this process. With HCS, you would build a "golden template" of the UC apps that your customers would be consuming.
The golden template is essentially an image of the UC App (UCM Pub, UCM Sub, UCxN, and CUP) that has parameters and configurations that you think every customer will be using. There are some caveats to what you configure since the provisioning tool, Cisco Unified Communications Domain Manager (UCDM), will be provisioning the system for you after you create the customer instances.
Once you have your golden templates, you are ready to start rolling out customers. You would clone the golden templates to create your new customer instance. Then you run what are called the "new identity" scripts on the cloned VMs. This new Identity script is built into the UC application (From 8.0 and later). It essentially involves you using the Answer File Generator on cisco.com to create an answer file for the application of interest and then you mount this answer file via a floppy image to your newly cloned VM. Once the floppy is mounted, you can go ahead and run the new identity script "utils import config" from the CLI of the UC app. It will rename, re-IP, change DNS servers, and lots of other platform information about the system that you can configure. Finally, it will reboot the system. Some of this process can also be automated using VMware's vMA toolset using scripts that the HCS team can provide.
Once the new identity script has been run, you have a new install for your new customer. Then you would input the new address information into UCDM and begin the bulk provisioning of the system. The UCDM would be bulk creating users, phones, VM accounts, partitions, CSS's, and just about everything else for the UC environment.
Once again, stay tuned for some future automation enhancements in this area, but at current (HCS 8.0.2 and soon to be 8.6.1) this is the method for provisioning a new customer from scratch in VMware.

Cisco Prime Collaboration Deployment with BE7K and VMWare license

Hello, I am looking for some help trying to figure out if Cisco Prime Collaboration Deployment can be used to upgrade our existing 7.1.5 cluster. From what I have read there is a API problem with the VMWare license that comes with the BE7K. But after reviewing the BOM/quote from my VAR it lists the foundation license which based of the release notes is supported.
UCSS-U-VMW-FND-5-1
UCSS Cisco UC Virt. Foundation Five Year - 1 server
Has anybody out there had expericne with PCD and BE7K'?
This is from release notes of PCD
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/rel_notes/10_5_1/CUCM_BK_P139675A_00_pcd-rns-1051/CUCM_BK_P139675A_00_pcd-rns-1051_chapter_010.html
Search for “Business Edition 7000” and it will state it is not supported with PCD. It is because the licenses that the BE 6k and 7K are shipped with don’t enable certain VMware APIs that PCD needs.
“Virtualization Software License Compatibility
Cisco Prime Collaboration Deployment is not compatible with all license types of VMware vSphere ESXi, as some licenses do not enable required VMware APIs.
The following are compatible with Cisco Prime Collaboration Deployment:
Cisco UC Virtualization Foundation (appears as "Foundation Edition" in vSphere Client)
VMware vSphere Standard Edition, Enterprise Edition, or Enterprise Plus Edition
Evaluation mode license
The following are not compatible with Cisco Prime Collaboration Deployment:
Cisco UC Virtualization Hypervisor (appears as "Hypervisor Edition" in vSphere Client)-preloaded on Cisco Business Edition 6000 and Business Edition 7000
VMware vSphere Hypervisor Edition
Any help would be appreacted.
JP

Thanks Jamie for repsonding, we haven't made any purchase's yet but I wanted to ensure we are purchasing a solution that won't lead to a lot of frustration. We only have 1000 phones so we are pretty small and the BE7K seems to be a good fit and value.
Cheers,

Influxis to Host Collaboration Service

Dear LCCS Customer,
I’m pleased to announce Adobe and its partner Influxis have reached an agreement resulting in a hosted collaboration service offering based on Adobe’s LiveCycle Collaboration Service (LCCS) code. The new service will be known as Influxis Collaboration Service and is targeted to be up and running by early November, 2012. Influxis has been a trusted Adobe partner for 6 years, starting as a Flash Media Service hosting company and is now a leading interactive media delivery provider specializing in video solutions. Learn more about Influxis at http://ics.influxis.com/.
Influxis Collaboration Service will be built to support the same framework and offer the same feature set currently available via LCCS. Influxis welcomes all Adobe LCCS customers to migrate to Influxis Collboration Service. Initial services will include dedicated servers for enterprise customers and others interested in having their own personal server environment. Shared server hosting will soon follow and be in place by December 2012.
In order to minimize impact and in an attempt to make the transition from Adobe to Influxis as seamless as possible, Adobe will continue to run its LCCS service in parallel until December 31, 2012. During this time, Adobe will also provide Influxis with ramp-up support as needed.
Transition planning is well underway. Influxis has already begun working with Adobe LCCS customers to exchange ideas on how best to achieve a successful transition. If you are interested in talking to Influxis about their service offering please contact Wesley Daggett at 661-775-3936 or via e-mail [email protected]. In the coming weeks Adobe and Influxis will provide additional detail about the specific transition plans on the LCCS Forum - http://forums.adobe.com/community/livecycle/lccs.
Adobe and Influxis are excited about this new opportunity and will work together to ensure a successful transition for customers who choose to make the move from LCCS to Influxis Collaboration Service.
Regards,
Jeff Stanier
Group Product Manager - LiveCycle

Jeff,
Is there anyway that I can get a LCCS account to develop with whilst there is this limbo period before Influxis comes online with their paid service?
I am literally just trying to get the skeleton working while waiting.
Any help or insights from the community as well are welcome! :-)

Hosted Voice Solution

Hi Guys,
Any one of you have worked on hosted voice solution? Can you please let me know what kind of hosted solution is available and it positive and negetive aspect?

Cisco's formal HCS offering, supplied by approved partners*, is the only official one these days. There used to be partners offering other options where multiple customers would co-exist on one CUCM cluster but the CSS/partitions would keep them separated. To my knowledge, these are all deprecated since the HCS announcement. Of course, there are non-Cisco offerings out there too.
The HCS offering is actually pretty decent, mostly because it's the same CUCM/CUC/IM&P/etc. products that customers can install on-premise. There are essentially two differences:
The required infrastructure to setup an HCS pod is prohibitively expensive for anyone except the big players. It's mostly carrier-grade equipment that an end customer would never buy.
The products are abstracted behind a provisioning/billing application (telecom parlance calls this Operations Support System or OSS). Last I checked this was Voss product that Cisco was OEMing. This is the only difference that really matters to you because it sets up the dial plan and such with some assumptions that you wouldn't otherwise be confined to if programming CUCM directly.
Editorial comment: Whether this is good or bad depends on the customer. CUCM is very flexible because it has such a huge install base across so many market sizes/verticals. It can be shaped to fit most custom requirements; however, the OSS toolset takes a far more cookie-cutter approach.
Other than the OSS toolset, it's essentially a normal Cisco UC deployment: they simply connect the VRF instance for you as a tenant in HCS into your WAN. After that it's effectively a Centralized Call Processing model. Normal voice gateway/SRST options at the offices and IP phones or Jabber for users.
*Full disclosure: my employer is one of those partners.

ARP Poisoning & Cisco IDS/IPS Solutions

I am trying to find out if someone familiar with Cisco's IDS/IPS (network and/or host-based) solutions can tell me if the product(s) can identify and/or prevent ARP poison routing attacks. If so, does it require customizing signatures or is there out of the box detection signatures?
Thanks for any information

There are some. Go here and do a search for "arp":
http://tools.cisco.com/security/center/search.x?search=Signature
Perhaps it goes without saying, but remember that the sensor has to see the relevant layer 2 traffic for these to work.

Cisco Prime Collaboration Deployment - Not able to mount NFS

Hi everybody,
We are trying to add an ESXi server to the PCD, but we are unable to succeed due to an error while mounting the NFS unit.
We get the following message:
"Failed to mount Cisco Prime Collaboration Deployments export as NFS store to the ESXi Host"
In the PCD we obtain the followings logs I attach the file.
We are using a VMware vSphere Enterprise Edition
The ESXi, has the VMkernel port map to a different subnet that the management subnet.
VMkernel: 10.11.202.75
VMmanagement: 10.11.200.75
To Add the ESXi host we are attacking the 10.11.200.75. Someone knows if the VMkernel must be in the same subnet for the NFS to mount?
2014-11-07 14:17:26,711 WARN [pool-1-thread-18] validation.ESXiValidation.isDSinESXiHost - Datastore PCD_NFS is NOT connected to ESXi Host 10.11.200.75

Thanks in advance.

Hi everybody,
Finally it turns it was a problem with the ASA. We apply a predefined rule in the ASA to allow NFS. We discover that the rule was not correctly defined, after creating a specific rule everything work just fine.

In general, the Trustsec design and deployment guides address the specific support for the various features of the 'whole' Cisco TS (and other security) solution frameworks. And then a drill-down (usually the proper links are embedded) to the specifc feature, and then that feature on a given device. TS 2.1 defines the use of ISE or ACS5 as the policy server, and confiugration examples for the platforms will include and refer to them.

Cisco Prime Collaboration Usage

Hi,
Many Asia costumers complain it is very difficult to maintain the Cisco Collaboration system.
So we are considering the Cisco Prime Collaboration system, see which can help or not.
I have few questions about the Cisco Prime Collaboration Provisioning (CPCP) for SME customer / Cisco Prime Collaboration Assurance (CPCA) for Big customer.
1. CPCP Standard version is free? one cluster? no adv. features? What is the adv. features on adv. versions?
2. I see the CPCP will deploy the new configurations into the CM clusters, that is fine on the new CM, but the existing CM will access the CPCP push into new configurations? Any impacts will happen on delopying the new CPCP into the existing CM?
3. CPCA lic. counted by every end devices, that is really expensive. Any cost effective methods to deploy the CPCA?
4. If we want to monitor the TP endpoints or DX video phones, I have to plug the lan to the 37XX or above switches? 29XX cannot?

Hi,
Been out of the office but see that no one has yet responded to this. I can answer some of the questions.
1. CPCP Standard version is free?
CUCM 10+ users are entitled to use the Standard version.
one cluster?
Yes
no adv. features?
Not missing a lot, especially for smaller one cluster networks.
What is the adv. features on adv. versions?
The Standard and Advanced versions are pretty much the same except for the following:
Advanced can handle multi-cluster networks
Advanced allows administrator delegation. This means that different administrators can be assigned to different groups of end-users.
Standard does not have advanced workflows (Approver, MAC assigner, Shipper and Receiver).
Advanced provides a northbound API for integration to another network management application, HR system or custom UI.
2. I see the CPCP will deploy the new configurations into the CM clusters, that is fine on the new CM, but the existing CM will access the CPCP push into new configurations?
CPCP can push configurations to new or existing clusters. Changes made directly on a cluster will be pulled back to PCP so they stay in sync.
Any impacts will happen on deploying the new CPCP into the existing CM?
CPCP was designed to add to a UC network at any time. When added to an existing network, CPCP can use it's reverse sync process to import users and CM configurations.
3. CPCA lic. counted by every end devices, that is really expensive.
List price may appear really expensive but you need to work with a sales person to determine the actual price. There is also the option to have an enterprise license agreement which might be more cost effective if this is for a Big Customer.
Any cost effective methods to deploy the CPCA?
ELA as mentioned above, or use the free standard version. It the standard version provides enough functionality, it might be an option. Cost effective may be hard to define. If the product significantly lowers the cost to operate the network (faster fault resolution, less administrators, usage reports, resource utilization savings, etc.) it would be cost effective. I don't know how big the Big Customer is or what/how many endpoints/devices/apps are in the network so I cannot provide any better advice.
I am not sure how to answer the last question so will leave it for a TME or other expert on CPCA. It looks like a medianet question. CPCA is not completely dependent on medianet to monitor TP environments and can provide some call trace and performance without it. This is best answered by someone on the Assurance PM/TME team.

Cisco Prime Collaboration 9 cannot discover ipphone

Hi Folks
I am testing Cisco Prime Collaboration ver 9.0.24376 in my lab environment, Im using it to discover CUCM Cluster version 8.6.2 and successfully to obtain Server and Gateway information, but I can't see any endpoint that registered to CUCM shown on Cisco Prime Collab dashboard.
I am also test to discover my 2nd CUCM Cluster version 9.0.1 and also successful with CUCM Server component but not for the endpoint.
I follow this guide to ensure CUCM side already configure properly.

Cisco Prime Collaboration and SIP Codes

I am trying to position Cisco Prime Collaboration with a Cisco CUBE router and the client wants to know if Prime will be able to do the following:
1) Scan, index and alert on configurable SIP 4xx, 5xx, 6xx
2) Look at acive inbound/outbound calls

Hello Varda,
It seems as the 1040 sensors are not finding the TFTP server. The TFTP server list should not contain the ipaddress with values 32 or 92 in their octets,
1. The 1040 needs to learn of the TFTP by DHCP option 150.
2. Please make sure that it is set on your DHCP server.
3. To confirm that the 1040 sensor is receiving the TFTP IP open a web browser and type http:// and see if the TFTP address field is showing the IP.
4. If it is then you might also need to restart the TFTP service on the CUCM so that the 1040 can download the cnf and image files.
Attached is the userguide for 1040. Go through it and this should be able to resolve your issue.
This is a other method to check the sensor is fine
Fist step install download winagents tftp server ,
enter a Service Monitor Server   Configuration / sensor1040 and in TFTP server enter    ip address(winagents tftpserver) and go to SETUP
in setup   put you ip address in PRIMARY SERVICE MONITOR and push OK   you look the server write file in (TFTP server )
Next STEP
Go to MANAGEMENT   and add new sensor you need mac address remember second port in sensor is span port you can make a sencond file in the tftp server
Next STEP
go to service monitor server and copy file *.img CSCOpx/
Next STEP
Search you dhcp server switch     option 150 in put your ip address tftp server when sensor power off and power on the sensor search tftp server and search files to autoconfig and register to service monitor when test is ok
its time to upload change winagent tftp server to callmanager tftp server
Hope this helps
Thanks & Regards,

Hi
As long as this is new instalation I recommend you to use SIP on all of the end points where possible and integrate with CUCM using sip trunk this will give you two main benefits
- the transformation of the called and calling number from and to CUCM will be easier
-if have end point using H323 and communicating with other end using sip the vcs will do internetworking to this call and you will need license for each internetworked call plus the media path will go through the vcs not direct between end points for internetworking
If you use sip make the end point name/sip usri as [email protected] Calls from vcs to CUCM use search rules with trsformation so if end point dial 123456 only from vcs and the default call is sip vcs will send it to CUCM as 123456@sip domain.com you need to do transformation before sending it to CUCM and send it as 123456@cucmip.
This is just in brief and also using the expersss way you can have your sip domain registered over the Internet and configure dns srv record point sip ton the vcs public ip and Internet calls can come to your end point sip name directly no need to publish ip to others to dial you
