Is WAAS Central Manager needed for SRE?

Hello experts,
We're planning to deploy just WAAS SRE in 3945 routers at multiple sites? Do we need to buy WAAS central manager? also can WAAS SRE be configured from command line and able to save the config to text file just like on router's IOS?
Thanks

Hi,
For your setup to be supported, you need to have all of your WAAS devices registered to a Central Manager.
Will it optimise connections if you don't? Yes it will but if you run into any issues with it, you will be on your own...
Regarding the configuration, you need to have the module imported into a CM but you can do all of the config from the CLI if you prefer and only use the CM for statistical reporting.

WAAS Central Manager - Procedure for changing FQDN and ip address

Software version 4.1.1c
I have the need to change my waas central manager hostname, doamin name and ip settings. What is the proper procedure to do this in order to keep the cm synchronized with the waes. I seem to have them out of sync now. Do you deregister all the waes first, change and reboot the cm, then register them again?

Advice for WAAS Central Manager?

Hello,
We are building a WAAS lab (not production) for a customer and we recently discovered that we can't use the NME-WAE-502-K9 as the central manager which was very affordable. So we are very disappointed about this. The other equipment are Cisco ISR 2811 (very affordable for building WAAS) with NME-WAE-502-K9 running WAAS 4.1.1 acting as the application accelerators. I have some questions and asking for some advice about some alternative options for us to consider:
What is the cheapest/smallest WAAS option we can use for the WAAS central manager? The only thing I could find is the WAE-512-K9, but maybe there is something else that is smaller and cheaper for consideration.
From what I read, after WAAS software version 4.1.1 it requires the Enterprise and Transport Licencing. Does the WAAS central manager have a 30,60, or 90 day trial that the CM can run before a license is required like most of the Cisco Unified Communications products today?
Thanks in advanced!

A central manager is required to managed all of your accelerators properly in a supported configuration. You don't necessarily need a physical appliance though. There is also the virtual form factor (vWAAS is the accelerator version and vCM is the manager version) that can run on a ESXi hypervisor.

Renewing Self Signed Certificate for WAAS Central Manager

Hi,
We would like some help from you about the following: We have an WAAS Central Manager which its self-signed certificate validity has expired as showed below:
Validity
Not Before: Jul 7 00:47:06 2009 GMT
Not After : Jul 6 00:47:06 2014 GMT
We have used its certificate to install some other remote WAAS Express routers.
We would like to know the following:
1. is it possible to renew this certificate? or
2. do we need to reinstall another certificate on CM and replicate this new one on these waas express remote devices?
If affirmative for at least one of them, please, could you share any document that describe how to do it?
I have attached some output commands from our CM.
Thanks,
Marcelo

Https certificate on WAAS Central Manager

Hi,
I wanting to know if it is possible to authenticate the WAAS central manager with a different certificate/key pair than the self-signed certificate/key pair.
I can't find any information about installing my own certificate/key pair.
Thanks in advance

We do have an option for the same:
First you may generate a CSR using:
http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v531/command/reference/execmds.html#wp2773266
Once done you can get the cert and import cert and keys on Central Manager using admin option
http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v531/command/reference/execmds.html#wp2773369
"admin"
Specifies that the certificate and key are for the Central Manager admin service. This option can be used only on the Central Manager.
The Central Manager admin service uses a self-signed certificate and key by default. You can use the crypto import pkcs12 admin command to import a custom certificate and key in PKCS12 or PEM format. If you delete the custom certificate and key, the self-signed certificate and key again become active.
Hope this helps,
Swati

Cisco WAAS Central Manager

Can someone tell me how to deploy Cisco WAAS Central Manager to manage 100 WAE devices over WAN? Is there any additional devices need to setup redundant design and any license cost included here per device basis to monitor? I need detailed solution to manage WAE devices centrally.

Vinod,
There is no need to buy additional licenses or no need to add per device license on the central manager. You can go with the 294-4G or the 474 device , these can support upto 250 devices. However would suggest you to go with a higher model so in future if you expand , you might want to replace the CM that time.
Also a central manager cannot work as a inline or wccp device nor it can do any optimization.

WAAS Central Manager Replacement

I have need to replace a WAAS Central Manager (4.4.x). The replacement would have a new IP address. The planned path of migrating is first to setup the replacement as standby and once sync'ed promote to primary. I will then manually update the WAE devices with new IP address.
OLD CM:
WAE# configure
WAE(config)# central-manager role primary
WAE(config)# cms enable
On the standby device, execute the following CLI commands:
WAE# configure
WAE(config)# central-manager role standby
WAE(config)# central-manager address new IP
WAE(config)# cms enable
Is this idea the best approach?
Any idea if the SSL certificates would have to be revoked and re-issued (whether self signed or otherwise)?

Hi,
The steps to replace a CM hardware have been documented under the following bug:
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtz47138
Basically, the steps are the following:
If the CM will be using the same hardware and IP you can restore the CMS database.
If the CM will be using a new name or IP, use the workaround provided by CSCsi59886:
1- Add new CM as standby
2- Make it primary
3- deactivate former CM in new CM GUI
4- delete former CM from new CM GUI (and make sure it s gone from the DB)
5- 'cms deregister' on former CM CLI
7- rename former CM, change its mode and reload.
8- rename the new primary and change its IP address
9- Change the IP and mode of former CM and register it

Can I create a report at WAAS central manager based on server IP address

Hi,
I have two distinct applications running at port 8080 for which I would like to have separated performance reports at Central Manager. Is there any mean to do that by using server ip address for example? If so how? Do I need to change policy? If so is that the only way?
Thanks
Wilhelm

Hi Rulix,
The latest version of CR Server is 2008. Therefore I'm assuming you are using CR Server 2008.
New in CR 2008 is the .NET report modification software development kit (SDK). The report application server (RAS) SDK is now available for users of Crystal Reports .NET API without the use of a RAS server. Report modification such as changing, adding, or removing database providers, or adding, removing, or creating report objects, parameters, formulas, and sections can be achieved by accessing the RAS SDK through the Crystal Reports .NET SDK.
Java developers however receive the JRC and Java SDK documentation through the free Crystal Reports for Eclipse download. This product will be updated on a separate schedule from Crystal Reports.
Further Information and samples are available in our [Developer Library|https://www.sdn.sap.com/irj/sdn/businessobjects?rid=/webcontent/uuid/5001d5de-f867-2b10-00bf-8d27683c85a0]
Kind regards,

WAAS Central Manager version 4.1

Hello,
I have to prepare a design of a WAAS deployment for my customer. I have an issue with the 4.1 version: Does i have to use an appliance dedicated for the management or i can use an WAE-512 with entreprise licence for managament and for WAN optimization features?
Thank you in advance

In any version of WAAS the supported configuration is to have a minimum of 2 application accelerators and one central manager. You cannot run the Central Manager and Application Accelerator on the same device.
The enterprise license unlocks specific features, notably CIFS acceleration but will not influence the number of required WAE's.

Re: WAAS/Central Manager, do WAVE594 NEED connectivity to CM for optimization to another WAV594? can i install CM later?

Can I install the End WAVE appliances and have optimization working, and install CM later?

Hi Matt,
It should be possible for you to do that - running with default optimization policies, which are on pr. default in a WAVE/WAE appliance.
Check by doing a show run on the WAVE-594 ... you should see a lot of class-maps etc.
You might end up with slightly better optimization results, when you can trigger the policy to your specific needs and enable some non-default features.
Best regards

Adobe application manager needed for CS5

I just d/l and installed 3 updates for AI, ID, PS from the Adobe site. The update application isn't working. After d/l and trying to install Adobe Bridge 5.02 twice, I've gotten the same error message:
Adobe Application Manager is needed to resolve this problem, however it is missing or damaged. Download a new copy of Adobe Application Manager or install this product again.
It must have been working to do the other updates. I just d/l the Applications Manager for CC, which says it works for CS5, but to only run if I get one of 2 error messages:
Adobe Application Manager is needed to update your product.
Adobe Application Manager is needed to start your trial.
My error message is different but to me, implies the same thing. Should I install it?
I'm on a mac 10.9
thank you

Thank you for the response Jeff. I had just installed the Adobe software on a brand new computer that had just had a clean install done by Apple less than 48 hours earlier. I don't use Adobe Cloud or any of the online services. The Adobe Updater appeared after I opened ID for the first time.
"The tool removes installation records for prerelease installations of Creative Cloud or Creative Suite applications. It does not affect existing installations of previous versions of Creative Cloud or Creative Suite applications."
Does this mean that there were some prerelease installation files on my CDs? This just doesn't make sense to me unless it's possible that something traveled with a document from my previous computer. I never had any trouble with CS4 and CS5 existing together before.
Does this change your thinking at all?
Thank you!

WAAS Central Manager Policy Definitions across several device groups

Hi there,
I am trying to find a way to apply a custom application policy(s) to multiple device groups. ( not the AllDevicesGroup).
I have not found a way to export or import the policy.
Any help would be appreciated.
Todd

I have my "Core" WAE's in a separate device group to prevent them from recieving a policy or setting intended for Edge WAEs. For example, If someone sets the assignment method to hash, I certianly dont want that pushed to my Core, ( using Mask assignment)
However, a custom application definition WILL need to be applied to both Core and Edge WAE's. Therefore I need a way to create the policy for all devices group and copy out and apply selected custom policies to the Core device group as well.
Problem: I have QUALYS Vulnerability Scanners that wreak havoc on WAE's by opening 1000's of sessions and not propoerly closing them, causing TFO Overload conditions, throughout the network.
Solution: create a custom policy to set Scanner IP action to pass-through. there are 30+ scanners so the match condition is lenthy and woudl be painful to build manually for each device group.
new Problem: need to apply this to multiple device groups.

Linux WWAN manager needed for Satellite M505-S4945

I am searching software wwan manager M505 -S4945 for a Linux. Because my modem is not detect in ubuntu. If you can soft for Linux..i really needed...thank's

Hello
From Toshiba there is no software for Linux because only Windows is supported but maybe external programs will work and you can find something for your modem and Ubuntu.
Everything what I have found is an article about useful Linux websites. Maybe its useful:

WaaS Central Manager - device serial number report available?

Hi folks,
just wondering if anyone knows a quick/easy way to talk to the WAAS database to pull serial number information for all of my WAE's installed. i have 35 devices scattered around 7 states and I'm hoping for an easy way to collect serial number info.
I was hoping the platform report from the CM would do it, but it does not provide serial numbers of each chasis, only model and software version.
My thought is the CM probably has this data somewhere? I'm hoping to avoid having to manually telnet to 35 appliances and run the command 'show inventory' to find the appliance I am looking for.
anyone have a good shortcut?
also - anyone know what the database format is? mysql? postgres?

The best way to collect serial # remotely from a WAAS device (WAE) is by executing 'show hardware'. You may write a script to get it.
CM don't provide this info currently.
Can you please unicast me at '[email protected]' so that I will be able to understand your requirements.
thanks
Nat

WAAS installed without Central Manager. not compressing traffic

Hi,
I installed 2 SRE modules in 2 ISR G2 router and configure them without Central Manager, but they are not doing compression, Traffic is going to Branch to Head Office but without compression.
My configuration is similar to this link
http://2and2is5.wordpress.com/2011/03/30/configuring-cisco-waas-on-a-sre/
I want to compress http, exchange and cifs traffic.
I don't have Central Manager, could WAAS works without Central Manager ?
Can anyone help me with that.
Thanks in Advanced.

Hi Arslan
WAAS requires a Central Manager however once they are setup it doesn;t technically require one in order to continue to to optimise traffic. If your WAAS environment is setup correctly and is intercepting the traffic http and CIFS should automatically been compressed with LZ compression. WAAS can accelerate Exchange however it depends on how your Exchange environment is setup and whether it is encrypted? If its encrypted via SSL you will need a WAAS Central manager to accelerate it.
To check if you WAE's are running correctly type in "show cms info" on the WAAS and you will probably see your WAE is status is not online:
WAE2#sh cms info
Device registration information :
Device Id                            = 3107921
Device registered as                 = WAAS Application Engine
Current WAAS Central Manager         = ##.##.##.##
Registered with WAAS Central Manager = ##.##.##.##
Status                               = Online
Time of last config-sync             = Mon Sep 24 13:18:51 2012
CMS services information :
Service cms_ce is running
You can check the accelerator status with the below command:
WAE2#sh accelerator
Accelerator     Licensed        Config State    Operational State
cifs            Yes             Enabled         Running
epm             Yes             Enabled         Running
