Adding stateful failover to running configuration

Hi,
I have failover pair of ASA boxes without configuration of stateful failover. There is only basic LAN failover.
I want to add stateful failover configuration using dedicated interface of ASA. Is this with downtime zero when I will add command for stateful failover?
Thanks
Peter

As far as I know it won't affect traffic flow and there's not gonna be any downtime.

CBAC Stateful Failover HA: ¿can it be used for three segments?

Hello team.
I need to protect three segments (inside, outside, DMZ) with two routers running CBAC and Stateful Failover High Availability.
I would like to know if the concept shown with two sample segments (inside, outside) in the documentation (http://www.cisco.com/en/US/prod/collateral/routers/ps5855/white_paper_c11_472858.html) can be extended for routers with three interfaces, each one attached to the segments I need to protect.
If this is a supported scenario, I would appreciate your pointing me to a sample configuration.
Thank you very much in advance.

Rogelio,
Basicamente seria HSRP groups asi como el ASA usa el stateful link, el Router establece una asociacion con un IPC group que se configure por HSRP group:
Mira el siguiente link:
Step 6
ipc zone default
Example:
Router(config)# ipc zone default
Configures the interdevice communication protocol, Inter-Process Communication (IPC), and enters IPC zone configuration mode
Use this command to initiate the communication link between the active router and standby routers.

Error while running Configuration Wizard in SharePoint 2013: Exception in RefreshCache. Exception message :The '?' character, hexadecimal value 0x43A0, cannot be included in a name. Line 1, position 5694.

Hi Friends,
I was trying to run configuration wizard in SharePoint 2013 Central Administration and I got below error:
Exception in RefreshCache. Exception message :The '?' character, hexadecimal value 0x43A0, cannot be included in a name. Line 1, position 5694.
Yesterday my SharePoint server was running fine and today when I try to update a SharePoint solution (wsp) I got same error. Even if I try to do any operation
in Central administration like adding new WSP, Updating WSP , I get same error.
Does any one have any Idea?

PO for LAN failover and stateful failover link?

Hi.. We have 2 x ASA 5520s running ver 9.0. We plan to aggregate the 2 interfaces used for LAN failover and stateful failover into a lacp PO. So both the ASAs are connected to each other directly using these 2 interfaces and then we logically make it a one PO. We then assign the PO intface an ip. Is this supported?

You can use any unused interface (physical, redundant, or EtherChannel) as the failover link. (Source)
That said, It would be an uncommon implementation. I almost always see them on separate physical interfaces.

Slow stateful failover for mission critical applications

I have two CSS running vip redundancy,ip interface redundancy and redundant-index on a ASR active-backup model.
They are attached to separate 3750 which share vlan info via a port channel.
When the master fails, we see the VRIR negotiation and mastership of VIPs occurs normally but the script that we run to validate our services fails and the services go to a down state.
Since the gateway for the reals is a redundant VIP that stays alive always based on a DUMMY service, we believe this could be a mac address table update on the 3750.
Traffic back from the reals is still sent to the "old" port where the gateway used to live.
Failover takes several minutes and TCP sessions timeout defeting stateful failover.
Any ideas???
Thanks

ER: expand Java Options field in run configurations dialog

Hello -
Any chance the Java Options field (in the "Launch Settings" panel of the "Edit Run Configurations" dialog) could become a multiple-line text box?
I add several options to this field for my projects and it is inconvenient to check the values when there are enough to scroll off the edge of the field.
Thanks.

[ There original post I made is incorrect. The classes/shared libraries need only to be available to the server - they do not need to be available to ALDSP Studio, since the database is access via the server. Double check that the required classes/shared libraries for your jdbc driver are available to your server ]
I searched our CR database for the stacktrace/error that you have and found serveral CR. Most of them indicate the problem was jar file(s) for the jdbc driver were not present in the client classpath. So - whatever you added to the server classpath (and PATH - if there were also shared object libraries) - we need to add those to the ALDSP Studio (eclipse) classpath (PATH).
you can put the jar(s) in
aldsp_3.0\eclipse-plugins\dsp\eclipse\plugins\com.bea.dsp.ide.external_3.0.0
and modifying
aldsp_3.0\eclipse-plugins\dsp\eclipse\plugins\com.bea.dsp.ide.external_3.0.0\META-INF/manifest.mf.
There are two places in manifest.mf you will need to add the jar file - once under Bundle-Classpath and once under Export-Package.

How long I have to wail the Stateful Failover on CSS 11154 ?

Somebody knows when the next Webns release is expected to implent the TCP Stateful Failover on CSS with VIP redundancy configuration.
At the begining of the year, the Product manager said that will be available on the WebNs V6.
For information: Alteon WEBOS v8 has released this feature for more one year ago.

Show running configuration of Service Instance

What is the command to see running configuration of a service instance in 7600 router.

Hi Girish,
You do not have to add URLs. Adding URLs is for monitoring other unrelated instances.
Just add the agates to the instances and make sure they become visible in the left-hand-side pane of the ADM (on both machines).
This will enable you to go to the other ADM (on the other machine) with the link "Go to Native ADM"
Now if you want to display the instances of the other machines in your overview also, you have to add a Proxy ADM.
On both machines, add a proxy-ADM. This proxy-ADM points to the ADM on the other machine.

Is GSS do stateful failover

Hi,
Is GSS cabaple of doing stateful failover. Lets say if i have 2 ACE VIPs configured in GSS in Active-Standby mode. What will happen of existing connections in Active if it goes down?

Good morning,
The GSS is a DNS server, so it makes no sense to talk about connections on it.
In the setup you described, if the primary ACE VIP fails, the GSS will stop returning that VIP in the DNS replies and use the secondary instead.
What will happen to the connections on the ACE will depend on what made the VIP go down (and then we would be getting into the ACE topic), if for example the server went down, then, I'm afraid all connections will break. If however, just connectivity between the ACE and the GSS was lost, then, the connections will continue to work normally.

CSS 11051 Stateful Failover

We have received a note concerning stateful failover of the CSS series of products, where the CSS 110XX series doesn't support stateful failover, however the CSS 115XXX will. Here is the digest of the message;
On 3/6, Hosting Engineering and Operations issued an alert regarding the
CSS 11000 load balancer. This is an update to that alert.
Since that time, we have experienced another hardware failure of this
model device.
In response to this situation, the following has occured:
* Platform Engineeringis in the process of removing the CSS 11000
from the SOE. Itis on target to be removed in April.
* Operations hasre-inforced our escalation procedures with CISCO.
Qwest is to beissued a RMA immediately for this model.
* For newconfigurations including a CSS 11000, CCAR will require
an Individual CaseBasis (ICB) review and approval.
* For existing premiumand above customers whoes configurations
include a CSS 11000, HostingOperations is planning to replace them with
compatible device. These changes have been pre-approved by CCAR as long
as:
* the networktopology remains the same
* redundancy ispreserved
* CCAR gets notifiedof the replacement model so we can update our
records
* For existing basicand enhanced customers, we are drafting a
communique that alerts them tothe performance issues exerienced by Qwest
and providing suggestedalternative solutions.
In response to recent questions from the field.....
Stateful failover with redundant CSS 11000 Series Load Balancers:
The Bottom Line: Cisco CSS 11000 Series Load Balancers do not support
stateful
failover.
Will Cisco ever support this?: Yes, this is supported in the CSS 11500
Series,
known as Adaptive Session Redundancy (ASR)
I need this today, what can I do?: Choose an alternative product. The
F5 BIG-IP
load balancers support this functionality.
What is stateful failover anyhow?
Stateful failover is a technology that can maintain state information
between
the active load-balancer and the standby load-balancer. This state
information
can include: persistence mapping, telnet sessions, ftp sessions, tcp
session
state, etc...
Why should I be concerned?
Without state synchronization applications can break if there is a
failover from
the active to standby unit. FTP Sessions will be broken, Telnet
sessions will
be broken, and most importantly persistence state mapping will be lost.
What do I need to listen for to determine if stateful failover is
important?
1. E-commerce applications that require persistence mapping.
Persistence
mapping will keep a client session mapped to the same server for a
specified
amount of time. This is often important with shopping cart and other
e-commerce
applications.
2. Long-lived sessions. Whether they are planning to transfer large
files via
FTP or long-lived telnet sessions. Anytime a connection will be
required for a
long time and starting over is not an acceptable condition, then
stateful
failover is important.
Does this sound correct or is this a bunch of hot air?

Yes. Stateful failover, or ASR as it is sometimes called, is available on the CSS 11500 and Catalyst 6500 Content Switch Modules (CSM) load balancing platforms. It is not supported on the CSS 11000 due to architectural limitations of that platform.
Stateful failover is available on these Cisco platforms today.

Ipsec Stateful Failover issue with Dynamic-Map

Hi all, I have an issue with a couple of Cisco ISR 2921 in Ha Ipsec Stateful Failover configuration.
With static crypto-map, stateful works good, Ipsec sessions are correctly trasmitted from Cisco Active router to Cisco Standby router.
With dynamic-map and profile, stateful fails, Ipsec sessions are not correctly trasmitted from Cisco Active router to Cisco Standby router.
I tried different IOS version:152-1.T3, 152-3.T2 and 153-1.T but I have the same behavior.
Could you help me?
Marco

Yes it is supported. It is supprted on VAM, VMA2, VAM2+.

The Cluster Service function call 'ClusterResourceControl' failed with error code '1008(An attempt was made to reference a token that does not exist.)' while verifying the file path. Verify that your failover cluster is configured properly.

I am experiencing this error with one of our cluster environment. Can anyone help me in this issue.

Errors in few of the step while running configuration wizard for PI 7.0

hi all,
i have installed Netweaver 2004s (PI 7.0) quality. during installation i had chosen sld option to be my development system as i wanted to use just single SLD.
now for the post installation steps i had run Configuration wizard. i haven't yet implemented Note : 939592 : PI Usage configuration versus Central SLD as it says first i need to perform all CTC steps.
now in this i got error in few steps:
STEP1 : PI_00_This wizard will execute Postinstall steps of technical configuration for the PI Usage
the error was: CIM_ERR_FAILED: Object manager is not activated
PI_05_This wizard will configure the integration server for sld.
The error was:
Error: CIM_ERR_FAILED: User credentials are invalid or user is denied access
PI_09_This wizard will configure Role of Integration server
Not able to load function SXMB_SET_ROLE_TO_IS( Connect to SAP gateway failed).
What should i do?
Regards,
Priyanshu Srivastava

Hi Priyanshu,
"Object manager is not activated" simply means, that the SLD server is not started. So, please, first of all navigate to the SLD URL http://<host>:<httpport>/sld, login with an administrative SLD user -> Admininstration and push the star button.

This is in the category of "dumb" questions. I am adding a new iMac running

This is in the category of "dumb" questions. To my home office that includes
a 2003 power pc G5 running system 10.4.11, I am adding a new iMac running
Lion. Question - can you share files back and forth (e.g., a Word file, camera images) by simply
coupling the two computers through USB ports? As opposed, for example, by burning
a DVD and using that in the other computer.

Why wouldn't you just use the network to share files, then? Simply set up a folder on one of your systems (I would recommend the Lion system) for sharing, turn sharing on, and then connect to it from the other system.

Solaris 10 hangs on Running configuration assistant.

Hi all,
Yesterday I patched solaris using updatemanager (solaris 10 3/05 for x86 on a fujitsu scenic pc)
when i was finished i rebooted, goes down fine but when starting up it hangs att Running configuration manager/assistant and i can't get further.
I have tried to remove all hardware except the bootdisk and graphic-card from the machine, also tried to disable everything in bios that is not needed to boot ie serialports and so on but it stops at the exact same place, the same second as config manager starts the machine freezes.
Since i have had this installation for a while and have patched it before i draw the conclusion that it's something wrong in the latest patches..
Anybody else had similar problems???
Best Regards
Henrik
