Using WCCPv2 for inter-site redundancy

Hello,
I would like to use WCCP to enable dynamic redundancy between Web proxies located in two data centers separated by an L3 link.
Is this possible?
Thanks in advance,
Ade

Hello Dan,
I thought this (your concept) would be fine as well but the WCCP configuration guide for the Catalyst 4500 switch states that the cache engines should not be separated by a Layer 3 hop. That's the part that confuses me.
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/46sg/configuration/guide/wccp.html#wp1000978
Restrictions for WCCP
The following limitations apply to WCCP:
â¢A service group can comprise up to 32 content engines and 32 routers.
â¢All content engines in a cluster must be configured to communicate with all routers servicing the cluster.
â¢Up to 8 service groups are supported at the same time on the same client interface.
â¢The L2 rewrite forwarding method is supported, but GRE encapsulation is not.
â¢Direct L3 connectivity to content engines is required; L3 connectivity of one or more hops away is not supported.

Since using cloudflare for my site I'm having troubles with Firefox cache

Hello,
Since I'm using CloudFlare for my Site I'm having a weird trouble occurring only with Firefox (version 16.0.2 / Mac OsX.6.8), but not with Chrome or Safari.
When I navigate from the main page of my Wordpress Site to a single post, then back to the main page, then to another single post and back again to the main page, the browser displays a binary file instead of the normal page. After emptying Firefox cache the page loads again properly.
When I pause CloudFlare the trouble disappears.
I just ask here because this does not happen with other browsers.
The config of the site is : Wordpress 3.4.2 with W3 Total Cache Plugin and the browser caching enabled.
If disabling the plugins the problem remains the same.
Thanks in advance to anyone who could help.

Hi,
This is not a solution but one way you could try to troubleshoot this is through the [https://developer.mozilla.org/en-US/docs/Tools/Web_Console Web Console] opened via '''Tools''' ('''Alt''' + '''T''') > '''Web Developer'''. You need to have it open before loading/reloading etc. Clicking on GET, POST links provides detailed info including Content-Type, encoding etc. You can also right-click and select '''Log Request and Response Bodies''' to view the transferred data. Hopefully you would be able to find the cause and resolve it.

Can I use SRST for multiple sites wit separate 911 lines

Is it possible to use an SRST (like a 2911 CME/SRST) to support multiple sites.
We have two sites next door to each other. They are connected by fiber with Cisco switches (vlans) at box sites.
Can I use a single SRST and have two separate 911 POTS lines setup so that each site has it's own unique 911 associated with it?
I can create two separate Voice vlans for the two sites and I could have both 29xx interfaces in use (one for each VLAN), but can I separate the dialing out function so that each vlan uses a unique POTS line this way?
Any other solutions other than two SRSTs?

We have to keep the 911 dialing the same at all sites since I already had an idea like that ...but we use 911, 9911 and 8911 for everyone to reach 911 so that they are not confused during an outage.
We will just have to bite the bullet and order 2901 SRSTs for all our small remote sites.

How to use SSO for some sites

I have one SSO certificate provided in IE and some of my corresponding sites refer to this SSO while logging in.
This works perfectly well in chrome as well, however same sites do not recognize SSO certificate and prompt for Logon credentials while accessing in firefox

Hi Daniel,
Yes, you can use SSO for your purpose. One of the over-looked features of SSO is to use as configuration store. Especially for storing the credentials for accessing your external
systems.
Create an
affiliate application in SSO and save your credentials in there. And in send port, under security tab you can select the affiliate application to use the credentials.
Read this article on this topic. This article gives you the detailed information starting from access required to create affiliate application, ways to read data
from SSO.

Using SPSiteDataQuery for multiple Site Collections

Hi All,
I would like to query five contact lists on multiple site collections. I can query the lists using SPSiteDataQuery if they are within the same site collection, but I can not query the lists over multiple site collections.
Is there a method like SPSiteDataQuery that I can use to query lists over multiple Site Collections?
Many Thanks,
Colin

Hi,
As you have mentioned that: SPSiteDataQuery which can query multiple webs within the same site collection, but not across multiple site collections. You can't accomplish that easily.
The solution evolves from first using the SPSiteDataQuery class to run a query upon each site collection and then aggregating the results.
For detailed information, refer to the following article:
https://oidatsmyleg.wordpress.com/2009/08/13/cross-site-collection-query-almost/
Besides, here is a similar requirement post, you can take a look at:

Config for using 1242 for site survey

Hello, i'm helping a coworker, we have a 1242 and would like to use it for a site survey, but we are not able to activate the radio using conf t it is in light weight, are we missing something? were can i find a config example to use for this purpose?

Hi Alfred,
Converting a Lightweight Access Point Back to Autonomous Mode
You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.
Using a TFTP Server to Return to a Previous Release
Note This section does not apply to Cisco C3201WMIC and Cisco C3201LAP.
Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:
Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.
Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.
Step 3 On the PC where the TFTP server is located, perform these steps:
a. Disable any software firewall products, such as Windows firewall, ZoneAlarm firewall, McAffee firewall, or others.
b. Ensure all Windows files are visible. From Windows Explorer, click Tools > Folder Options > View > Show hidden files and folders.
Step 4 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, c1240-k9w7-tar.default for a 1240 series access point, and c1250-k9w7-tar.default for a 1250 series access point.
Step 5 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 6 Disconnect power from the access point.
Step 7 Press and hold MODE while you reconnect power to the access point.
Step 8 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.
Step 9 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.
Step 10 After the access point reboots, reconfigure it using the GUI or the CLI.

Inter chassis Redundancy License

Hi,
Could anyone tell me that I am having 2 Cisco ASR 1002 and I want to do Inter chassis Redundancy between these devices.
As per Cisco doc I found that Inter chassis Redundancy is available for ASR1002 but it is for Firewall/NAT configuration Replication.
And it need Cisco IOS XE 3.7S for inter chassis Redundancy and we need this license FLASR1-FWNAT-RED(=) for Replication of Firewall/NAT configuration.
These are links where I found this:
Inter chassis Redundancy on ASR 1002
http://www.cisco.com/c/en/us/td/docs/routers/asr1000/configuration/guide/sbcu/2_xe/sbcu_2_xe_book/sbc_interHA.pdf
Firewall/nat replication
http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_nat/configuration/xe-3s/asr1000/nat-xe-3s-asr1k-book/iadnat-stateful-int-chass.html
but I want to confirm that can it will replicate the IP data traffic as we doesn't have any Firewall/nat configuration or any other traffic except IP data.
OR
If I purchase this license mentioned before than it will replicate the Data configuration or not.
we also have to run VRFs, BGP and QOS also on these devices.
Please let me know if anybody know this.
Thanks & Regards

Hello Leo Laohoo
I know Rahul Chhabra. But my answer is not there where you told me to go.
As you told him to use HSRP, we don't want to use this protocol. Because this is configured on the interface level. If we will use this protocol we need the same number of ip addresses as the interfaces we are having on the routers. Thats why we prefer Inter-chassis Hardware Redundancy between 2 ASR 1002 routers, in this case we require only two IP addresses for the both the routers.
Now i want to know that we want to enable only routing on the ASR routers, for this do we need any license or not. If yes then which one license we have to purchase?
If not then please tell me the link from where have you seen that we don't require any link.

Should I use flex for my website

Hey, I am having trouble figuring out if I should be using
flex for a site similar to the BBC site:
http://www.bbc.co.uk. I have
started the site in flex but I am running into a lot of problems.
It could be that I am a newbie to Flex, but wanted to make sure if
I should still be going a head with this in Flex. Any advice would
be appreciated.
Thank you,
Vinny

I would say that if you don't know the answer to that
question, then the
answer is probably no. You need to have a pretty firm
understanding of how
sites like that work under the hood before trying to build
one in Flex.

Inter-site replication and KCC, when migrating from 2008 SP1 to 2012 R2

Hello,
We have a very simple AD infrastructure, two sites. I have built out a 2012 R2 server, extended the AD schema and promoted it to a domain controller. Reviewing the existing AD replication topology, we currently have a 2008 SP1 server as a DC
designated as the source/destination for inter-site replication, which appears to have been decided by KCC.
I will be decomming this 2008 SP1 server, having migrated off the FSMO roles to a few other DCs.
Will KCC automatically know to adjust the replication topology when the 2008 SP1 DC is offline? Should I demote it after migrating off the FSMO roles?
Thanks,
Matt

Hi,
Thanks for your post.
By default, the KCC reviews and makes modifications to the Active Directory replication topology every 15 minutes to ensure propagation of data, either directly or transitively, by creating and deleting connection objects as needed. The KCC recognizes
changes that occur in the environment and ensures that domain controllers are not orphaned in the replication topology.
For more detail information, you could refer to:
http://technet.microsoft.com/en-us/library/cc961781.aspx
For the migration, you could transfer the Flexible Single Master Operations (FSMO) Role and remove the Windows 2008 R2 domain controller, please refer to:

I am running 10.6.8 and using iweb for my web site. After several SEO analysis they all indicate I need H1-6 header tags. After looking at the source code I see there are none in iweb. Is it necessary to add? If so, how do I add H Tags to iweb.

I am running 10.6.8 and using iweb for my web site. After several SEO analysis they all indicate I need H1-6 header tags. After looking at the source code I see there are none in iweb. Are they necessary to add? Why would one add these tags and how do I add H Tags to iweb? And are there examples to look at? I am slowly learning about simple web design and assumed that iweb was stand alone without having to write code. Is this one of the reasons iweb is no longer supported? Thanks for looking at this!

A simple text page like this:
Heading
    sub heading
          text paragraph ....
Is traditionally represented by html tags like:
<h1>Heading</h1>
     <h2>sub heading</h2>
          <p>text paragraph ... </p>
I would guess that the use of h1-h6 tags helps search engines to understand the structure of a page as the tags imply a certain structure.
This can be compared to more generic tags like <div> that could represent any kind of content - and may be what iWeb uses (you'll have to check yourself).
I would generally recommend that you use some kind of up to date blog/site building tool, perhaps Wordpress or Squarespace (I haven't used either one myself) that support current web technologies - this should reduce your SEO issues and make it easier to properly support mobile/tablet users.

I have been using Safari for years and have always kept it on "private." Starting two days ago, I suddenly found myself unable to log onto my blog and many other sites that I normally log onto when private is set. This so annoying, I just switched to Firefox. I don't like Firefox nearly as much as I like Safari. What is happening? How do I fix the problem?
Thank you.

Might be a corrupted database ...
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
