Cisco Global Site selector Issue

Hi all ,
I have a cisco GSS-4492R-K9 in my network . Currently when I am trying to do any changes it is giving me a following error .
Couls anybody pls let me know why it is happening
GSS#copy run sta

your help is highly appreciable .
Rgds,

Most likely the storage device has become corrupted thus you see the filesystem working in read only mode.
There was a similar thread posted in the Application Networking forum about a year ago which suggested some remedies. Please see this link.

Cisco Global Site Selector

Hello
Looking at the datasheet for the Cisco ACE GSS 4492R GSS device, under Global Traffic Management
" The Cisco GSS 4492R can be deployed as a standalone global traffic manager that globally load balances client requests across distributed data centers using network performance metrics such as content use, round-trip time (RTT) between client and the closest data center, routing topology, and any device performance values that are available through SNMP."
The part that interrests me is the RTT between client and closest data center. Looking at the config guide and other documentation I can see how make balancing decisions based on the client DNS server and find nothing based on actual client.
So the question - Is it possible to make balancing decisions based on round-trip time (RTT) between the actual client and the closest data center.

Hi Neil,
The feature you are referring to is Network Proximity. The documentation could be a bit confusing because the "client" is relative. To you and me, the client is the person (or application) making the original DNS request. To the GSS, the client is that person's (or application's) local D-Proxy (DNS server).
When an application makes a DNS request to it's local D-Proxy, the D-Proxy will then attempt to resolve the request, but will source the request with it's own IP address, not the actual client's. Therefore, by the time the request reaches the GSS, the GSS has no information on the original "client" or application that originated the DNS request. It only knows the source IP address of the requesting D-Proxy and the domain it is requesting resolution for. So to answer your question, no, the GSS cannot make a load balancing decision based on RTT between actual "client" and data center because it does not have sufficient data to make such a decision.
In most cases, each actual client will be using a D-Proxy that is local to them, so the effect is the same as what you are asking for. But if the D-Proxy is remote to the actual client, then you could get unexpected results.
Hope this helps,
Sean

Ask the Expert: Global Site Selector Configuration and Troubleshooting

Welcome to this Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about configuring and troubleshooting the Global Site Selector (GSS) with expert Swati Chopra.
GSS devices represent the next generation of application switches and global server load balancing (GSLB) appliances. Working together with the Cisco ACE Module and Cisco ACE 4710 appliance, these devices form an application-fluent networking solution that improves availability, acceleration, and security for data center applications.
The primary role of Cisco GSS is to implement the business continuance and disaster recovery policies of a business by optimizing and securing the Domain Name System (DNS) infrastructure of the data center. It does this by integrating with the DNS infrastructure and responding to the client DNS requests, thereby directing the client to the site that is best able to serve its needs.
Swati Chopra is a CCNA, CCNP, and VCP certified customer support engineer for content switching, covering technologies such as Cisco Application Control Engine, Cisco Wide Area Application Services, Global Site Selector, Cisco Content Services Switches, and Digital Media Suite. She has been with Cisco for more than three years and has worked with most of the high-end customers on content-related complex cases.

Hi Sarah,
The load balancing mechanism for GSS requests is done via different methods. We can use these methods to define how the load is shared for different balance clauses within the same rule. The 6 methods we use are:
–round-robin—The GSS cycles through the list of answers that are available as requests are received. Each resource within an answer group is tried in turn. The GSS cycles through the list of answers, selecting the next answer in line for each request. This is the default.
eg: if we have 2 answers in answer group then GSS will provide them alternatively.
–least-loaded—The GSS selects an answer based on the load reported by each VIP in the answer group. The answer reporting the lightest load is chosen to respond to the request.The least-loaded option is available only for VIP-type answer groups that use a KAL-AP or Scripted keepalive, as they provide the GSS with detailed information on the SLB load and availability.
eg: if one answer has higher load than the other, than first answer will not be provided until its load goes down the other answers
–ordered—The GSS selects an answer from the list based on precedence; answers with a lower order number are tried first, while answers further down the list are tried only if preceding answers are unavailable to respond to the request.
for eg: answer with ordered number 1 will be provided first till it becomes unavailable. Once it is unavailable then answer with ordered list number 2 will be provided
–weighted-round-robin—The GSS cycles through the list of answers that are available as the requests are received, but sends requests to favored answers in a ratio determined by the weight value assigned to that resource.
eg: if one answer has more weight(80%) than the other answer(20%), then it will be used 8 times out of 10.
–hashed— When the GSS uses the hashed balance method, elements of the client's DNS proxy IP address and the requesting client's domain are extracted to create a unique value, referred to as a hash value. The unique hash value is attached to and used to identify a VIP that is chosen to serve the DNS query.
The use of hash values makes it possible to "stick" traffic from a particular requesting client to a specific VIP, ensuring that future requests from that client are routed to the same VIP. This type of continuity can be used to facilitate features, such as online shopping baskets, in which client-specific data is expected to persist even when client connectivity to a site is terminated or interrupted.
The GSS supports the following two hashed balance methods. You can apply one or both hashed balance methods to the specified answer group.
• By Source Address—The GSS selects the answer based on a hash value created from the source address of the request.
• By Domain Name—The GSS selects the answer based on a hash value created from the requested domain name.
for eg: a user using same source ip will get the same answer from GSS if we do source address hashing.
-DNS Race (Boomerang) Method-The GSS supports the DNS race (boomerang) method of proximity routing, which is a type of DNS resolution initiated by the GSS to load balance 2 to 20 sites.
The boomerang method is based on the concept that instantaneous proximity can be determined if a CRA within each data center sends an A-record (IP address) at the exact same time to the client's D-proxy. The DNS race method of DNS resolution gives all CRAs (Cisco content engines or content services switches) a chance at resolving a client request and allows for proximity to be determined without probing the client's D-proxy. The first A-record received by the D-proxy is, by default, considered to be the most proximate.
Use case is mainly with CRA's.
Hope this helps. Please feel free to revert if you have follow-up questions.
Thanks,
Swati

SAP LDAP Connector / UME LDAP and Global Site Selector (GSS)

Hi,
I'm wondering if SAP LDAP Connector / UME LDAP will work with Global Site Selector service, such as CISCO GSS 4400 Series, so that GSS can provide load-balancing for LDAP access.
If it works, is there a specific configuration on the SAP side?
Thanks in advance.
-denny-

Hey Denny,
Wondering if you ever sorted this out. I'm trying the same thing right now and UME is failing (and portal won't start) when I use the FQDN of the GSS. Behavior is strikingly similar to using the FQDN of the Active Directory domain. The only way I found to use AD as an LDAP source is to list individual DCs in the UME config. I'm hoping to use GSS instead.

Global Site Selector (GSS) support DNSSEC ?

Hi all,
When will GSS support DNSSEC ?
Thanks
Eric

Last I heard GSS currently does not support DNSSEC. It is a feature that is being
discussed for inclusion in a future release.
You should contact your sales contact at Cisco to get more information and/or express your need for this feature.

Anyone used the Global Site Selector yet ?

I believe it came out a couple of months ago. I'm looking at one versus the F5 3DNS boxes. Any thoughts ?

I haven't used it yet, but I am also interested if anyone else has some info on it.
I guess it would be a good idea to use if Cisco devices such as CSS 11000,Local directors, CSM etc. are deployed in the network.

On GSS(global site selector)network max configurable the number of backup?

HI..
I would like to know the max backup gss number when we configure gss network.
I did two gss when I configure gss topology. there are no problem when I configure two gss to active and the other standby.
but I read the cco document that the gss cluster is being max up to 8 gss box.
is it possible topology?
when I configure two more gss on one cluster, I occered the err log on primary gss.

ACE 4710- Global Site load-balancing

Does the 4710 have a feature like global site load balancing like the CSS?
We have a site that will have 2 ISPs but we don't have our own block of IP addresses to advertise so we would need to use the ISPs IP blocks. We've had issues in the past advertising one ISPs IP block out another ISP so I was wondering if there was a way we could configure the ACE similar to the way the CSS did global site load balancing. Basically have the ACE act as a DNS server and respond back with the IP address of whichever ISP we wanted the end user to come in on and use a probe to ping the ISPs remote WAN IP to verify the circuit is passing traffic and resolve the correct IP if it's not.
Thanks

ACE does not have DNS server functionality.
And these methods are not supported on the CSS anymore.
The solution we offer is to install a Cisco GSS (Global Site Selector) which can interact with the ACE or CSS or CSM to determine which vip is up or down.

Issues Working with Results of GetWebAnalyticsReportData(Global.Site,Global.ReportLevel,"TopPageForPageReport",$B4,$B5)

I created a custom Web Analytics Report in SharePoint. I went into the associated Excel file and tried to perform a vlookup to modify the report. No matter what I do, all references to any cell in the result ALWAYS end up as 0. I tried just doing a direct
reference to a cell and the result is 0. I tried changing the value to TEXT and it still is a 0.
So for example:
The returned array covers A31 to D2030. If I go to some random cell in the workbook and enter "=A32" instead of returning the value in the cell (or even the formula), it returns 0. It doesn't matter what is in the cell, whether text or number.
The formula in the cells are "=IFERROR(GetWebAnalyticsReportData(Global.Site,Global.ReportLevel,"TopPageForPageReport",$B4,$B5),$A31:$D2030)
The value in A32 is the URL of a aspx page.
I wanted to use a VLOOKUP to make the chart more readable since the URL is quite long and I wanted to strip out the common portion of the URL

Hi,
According to your description, Excel formula not working in the web analytics report.
I tried to open a “Site Web Analytics Reports - Top Visitors” report in the desktop Office application, select an empty cell, input something like “=D4”, it is populated
with the value of D4 cell immediately.
By default, SharePoint Web Analytics Service produce the analytics data and save it in an Excel file, then we should be able to manipulate this Excel file with its
data as what we do in a normal Excel file.
To narrow down the issue, I would suggest you create a new Excel file with some data in your local machine or other machines, test some simple formulas on it to see
if it is an issue of the desktop Office application.
Feel free to reply if there any progress.
Thanks

IOS 12.4(15)XW not available from Cisco Web site

Can anyone please tell me why this version is not available from Cisco Web site as I am trying to download it to test on a cisco 2851 series router .The documnet below in page 7 & 10 describe the requirement for this version. What is the replacement version for this if that is not available?

Well, maybe I am missing something but I do not see a 12.4(15)XW release on CCO for the 2851 platform. I see references to it in documentation but I don't see actual release notes or a download link. So, where exactly did you see this particular version for this platform?
Based on the PDF provided by the OP I think he is trying to add a fax module. In the PDF it is stated a few times that you can use 12.4(15)XW or 12.4(20)T. What this basically means is that these are minimum IOS version levels that you need to use that module. You would not want to run the minimum in most cases because software defects are abundant and seem to be endless. IOS release trains are somewhat over complicated in my opinion but here is my quick take. The XW is a early deployment release. These releases are "one offs". Usually added to incorporate a new piece of hardware. Sometime after these releases come out (again, to get the product to market) the code is incorporated in a T-train (in this case, 12.4(20)T). The idea is that the T-train code is used to introduce features/hardware/etc. that will be rolled into the next main-line release (in our world that is 15.0).
Back to your issue. I can't find 12.4(15)XW but apparently p.bevilacqua has been able to find it. Maybe he would be willing to provide the link. If that doesn't pan out, I suggest that you look at releases after 12.4(20)T (including the latest service release for 12.4(20)T). They go up to 12.4(24)T. T-trains are touchy so you have to do your research and testing. I have had decent success with 12.4(20)T until recently (MGCP and T.38 fax, no joy). I have also used 12.4(24)T with OK success thus far. I know that p. bevilacqua doesn't like the 12.4T train "because its buggy". My opinion is all of this software is buggy. You have to identify the minimum release that will work with your hardware. Go to the latest minor/service release and research the bug toolkit. Oh, and always test.
OK. Down the rabbit hole I go.
HTH.

Bill

DOM Based Cross-Site Scripting issue in RoboHelp 10

We're using a WebHelp system originally deplyed using RoboHelp 9.0.2.271, and a recent security scan revealed the DOM based cross-site scripting issue.
I recently upgraded to RoboHelp 10, migrated my help system to this version, and redeployed the system, but our security scan is still detecting the cross-scripting vulnerability in WebHelp. Wasn't this issue resolved in RoboHelp 10?
Thanks

Hi,
I’m not a security expert, but this script reads the URL of the current topic and redirects to the current topic with a bookmark. This is needed for when the same topic is used in multiple locations in the TOC.
I’ll ask around about this security issue.

LiveCycle ES2, Guides, SSL and IE 8/9 Cross Site Scripting Issue

I have a guide that is being served up in the workspace.
This guide works fine in all of the different browser versions provided they go through port 8080.
If however you enable SSL on your server (port 8443) and serve up the guide in the workspace, the end user can fill the entire form out only to have the browser identify the submit process as a Cross Site Scripting issue.
This is the result:
The data is essentially lost and guide disappears. I had a theory that maybe the submit process might be using the default server port for data submissions (8080) and created a customized submit process with the hardcoded targetURL.
I tried to test my theory and got the same result. I then modified my custom submit process to essentially do nothing (Started and ended the process with an abstract activity), and got the same result.
The only other thing that I could think of, is that the automatically generated action script classes might be hard coded to use default port instead of the SSL port.
Suggestions?!

Where can I download the scripts from cisco web site

hello :
I need some IVR scripts for my AS5350 but I cannot find them on cisco web site.
anybody can tell me where and what files, thank you

Hi,
unfortunately the TCLWare pack is not available in public. It can be downloaded only through the CCO. So, you need a CCO account in order to login inside and download it.

Module_data where clause using globals.site.dateNow

I'm trying (and failing) to get a list of blog posts that are excluding the not yet released posts, here is what I have:
{module_data resource="blogposts" version="v3" fields="id,siteId,blogId,postTitle,createBy,releaseDate,createDate,lastUpdateDate,enabled ,deleted,disableComments,slug,postUrl,metaBlogPostTitle,metaBlogPostDescription" skip="0" limit="10" where="\{'blog.releaseDate':\{'$lt':'{{globals.site.dateNow}}'\}\}" order="-id" collection="myData"}
The "query" works but it ignores the globals.site.dateNow and displays everything (including posts greater than today).
If I do a greater than (in testing), it doesn't display anything, it should have only displayed the unreleased blog posts.
Bug? User error? Formatting incorrect? Any tips would be great.

Hi Rich,
In your 'where' filter above, you are using, 'blog.releaseDate', if you want to filter the data based on the blog posts' release date then use 'releaseDate' only. Like this -
where="\{'releaseDate':\{'$lt':'{{globals.site.dateNow}}'\}\}"
Let me know if you need more clarification on this.
