Cisco Application :: Ace 4710 Response Sticky Only

Dec 15, 2011

I've been using my pair of ACE-4710s for quite some time and have usually stuck to the Class C Subnet sticky settings, as that's what we migrated from in Windows NLB.  In one instance of load balancing I'm trying to create an L4 inspection policy that looks for a certain payload (much like a http header) and would like to persist on this.  The problem is that the client portion of the conversation starts with a 'SessionID' of 0, and the server responds with a unique 'SessionID'.  If I setup the sticky policy with 'Enable Sticky For Response', I get entries populated in the sticky database, but they all go to the same server as there is a sticky session setup for the SessionID = 0.  Is there a way to setup sticky entries on server response only.Currently using ACE DM v4(1.0).

Cisco Application :: ACE 4710 SSL Cannot Configure Backup Sticky Network

Sep 24, 2012

I'm looking for some documentation I can share with a customer to explain why I can't configure them a back-up sticky server farm when we're not terminating SSL on the the ACE (we pass SSL from the client through to the rservers, sticking the client to the rserver by source IP address).  I've not been able to find anything that addresses this particular scenario in my googling so far.  I remember discussing this in my training class with the instructor, but I can't find any reference to it.  Have any of you run into this and have a link they can share?

Cisco Application :: ACE 4710 / Sticky Serverfarm / All Connections On One Server?

Nov 2, 2011

We are using a sticky serverfarm with 2 real servers, one server was down for maintenance for an extended period of time. When it came inservice again it was not getting any connections. is it because all the connections had stuck to the other server ?  we want sessions to be sticky but we also want to LB?I got it working by bouncing the server that had been online all the time. things started to LB then.BTW  the ACE 4710 is running 4.2.1

Cisco Application :: ACE 4710 Shows Over Weeks Dramatically Increasing Sticky Entries

Jan 24, 2013

I have a strange effect at my ACE 4710. I loadbalances normally reliable only 14 WEB-Services.
 
It's running on SW A3.25. Since several weeks I regognized a dramatical increase of Sticky entries. So when running in limitations (the stolen for reuse counter increased then) (show np 1 me-stats "-slb -v") gave more and more resources for sticky ... last it was at 65% and ran again into limits at round 650500 Sticky entries.
 
So I began to find out what of the services was affected with most sticky database entries and could Identify it. There were really to see round about640000 entries for that specific service.
 
The sticky for that service was defined to look at a specific cookie in the http header and the timeout defined is 120 minutes.
 
So round about 45000 Entries was to see with a "show sticky databse group Cookie_Sticky"  with a time-to-expire value of   zero   in the database like the follwing examüple shows:
 
timeout      : 120           timeout-activeconns : FALSE  sticky-entry          rserver-instance                 time-to-expire flags  ---------------------+--------------------------------+--------------+-------+  13765297814690832647 

[Code]....

When I modified my Sticky definition  with the command "timeout activeconns"   all the Zero-Entries were kicked out and the rsources used for Stickywent back to 5% of usage...

We want to mask part of the path prefix to hide development content: For example: the site(s) are: [URL]However we don't want anything with acme showing...so we would want the loadbalanced url to be: [URL] ...for requests and responses. I think this would be an http re-write request/response scenario?Is this possible to configure this on the ACE Device? We've got the load balance configuration down...not sure how to do this re-write type scenario?

Cisco Application :: ACE10-6500-K9 / How Static Entry Under Sticky Performs

Jul 26, 2011

how a static entry under a "sticky" performs Configuring Static IP Address Sticky Table Entries Cisco Documentation Says When you configure a static entry, the ACE enters it into the sticky table immediately. Configuring the ACE Action on Server Failure failaction purge # The purge keyword specifies that the ACE remove the  connections to a real server  if that real server in the server farm  fails after you enter the  command. The ACE sends a reset (RST) to both  the client and the server  that failed. Cisco Documentation Says If you do not configure this command, the ACE takes no action when a server fails
 
sample config
sticky ip-netmask 255.255.255.240 address source STICKY1
timeout 180   replicate sticky   serverfarm SERVERFARM1   8 static client source 192.168.12.15 rserver SERVER1
  
Question1 - What happens if SERVER1 fails?
 
a) Does the ACE let the connections to SERVER1 timeout(default behaviour) and then load-balance new connections coming in deom 192.168.12.15 to another server in SERVERFARM1

ORb)  Does the ACE reset the connections to SERVER1  immediately and starts  load-balancing new conenction coming in from  192.168.12.15 to other  servers in SERVERFARM1 ?

ORc) Does the ACE just drop the current and new connections from 192.168.12.15 till SERVER1 comes back up ?

OR d) Is it dealt differently?
 
Question2 - Now what happens if the failed server(SERVER1) comes back up after some time?
 
e) Does the ACE reset any current connections from 192.168.1.15 and starts sending them to SERVER1 ?

ORf)  Does the ACE leave the current connections from 192.168.1.15 to other  servers in SERVERFARM1 as they are and send any new connections
from 192.168.1.15 to SERVER1?

ORg) Is it dealt differently?
 
My guess is Question1 -> a) and Question2 -> e)
 
ACE model =  ACE10-6500-K9
Version =  A2(3.3)

Cisco Switching/Routing :: Track Down An Application Response

I am trying to track down an application response problem on my network (the traffic goes through a 6509 and FWSM).I noticed in one of my WireShark captures, that the client at times seems to be sending ackowledgements (ACKs) over and over again, and I'm not sure if this indicates a problem/ retransmission.
 
 Basically, a web server is delivering images to the client, but end users are complaining of slowness and freezes.Wire-Shark has not flagged this as a problem (comes up "green")

Cisco Application :: DNS Rewrite On ACE 4710?

Aug 26, 2012

I have an issue with a customer that wants to update a server behind the ACE. The problem is that when the application wants to update the server it does it with the name.Doing some research I found that you can rewrite the record DNS based on the static NAT you set up on the ACE. The feature is called DNS inspection. Is the same feature as the ASA (DNS doctoring).I apply it to the outside interface and it did not work.

Cisco Application :: ACE 4710 Lic Performance

Mar 19, 2012

With the current (A5) ACE 4710 lic setup, does the "X gigabit per second appliance throughput" that is licensed affect: -
 
A)  Only "appliance" i.e. load balancing traffic, any other normal routed traffic is not included in the limit
 
 or
 
B) Is it an overall throughput limit on the interfaces i.e. includes all traffic not only load balancing traffic but also normal routed traffic crossing the appliance
 
Looking at a scenario where the lic size I need for HTTP load balanacing would be one size if  A) but would need to be much larger is B) to accomodate out of hours routed backup traffic crossing the ACE 4710

Cisco Application :: ACE 4710 - SSL Over Port 80

Aug 11, 2012

I've got a web app that the owners want to run over port 80, but also using SSL to secure private data in transit.  The architecture is an ACE 4710 in SSL termination mode->Apache (port 2000)->Back-End app server.
 
I've got two VIPs set up already - one on port 443 and one on 2000 - both of which do the SSL termination quite nicely, but using the 3rd VIP set up on port 80, the connection steadfastly refuses to be HTTPS (i.e. doesn't show the padlock).
 
I've done all the set-up through the web interface so far, can this be done? If so, how?

Cisco Application :: ACE 4710 A3 (5) Logging New Connections?

Jul 31, 2011

We have recently transitioned one of our Ecommerce products to a new data center, at which we now use a one-armed load balancing approach rather then the routed load balancing approach we used previously. This is casuing us some issues as we generally log the source IP address a user comes in on when he fills out an application. Now the logs only show the natted ip address recieved by the load balancer, which does us no good. Any way to log the source IP address when a new connection is created to a particular vip?

Cisco Application :: ACE 4710 Take An Action When A Server Goes Down

Jun 2, 2011

If we use an ACE4710 to load balance two real servers, obviously it will use health checks to determine if a server is down.When it detects a server is down, it will not send it any more traffic.But can we also have it take any other action?  For example maybe email an admin, or send an SNMP trap?  Or better yet, can we use a custom TCL script to do other things, like launch some custom activities?

Cisco Application :: ACE 4710 To Manage The Ports

Jan 24, 2012

I am new to the 4710 appliance.Apart from the 4 GE 'data' ports, there are 2 Ethernet 'management' ("console") ports.  I find the description in the "quick start guide"somewhat confusing. URL, Is a first-time serial connection (at least to run the initial config. script) mandatory?  Or can you obtain the same result via one of the 2 Ethernet management ports and using a default ip address (192.168.1.10 ? When running the initial config. script (only possible from the serially connected console i suppose), you have to select your management port. Why does the system in step 5 proposes  you 4 ports, and not just 2? I suppose the intended port for management is one of the 2 management ports, not one of the 4 data ports?

When i access the website using https everything works fine and i can login to my account in https mode.When i access the website through http and login to my account the URL is redirected to https...normal because i am using action-list to rewrite the http into https. But when i exit the browser and access the website again using http it is not redirected to https(although i see that i am still login into my account i can see all the inforamtion in my account).

Cisco Application :: ACE 4710 - Management Only Interface?

Apr 25, 2012

Am trying to replicate the managment interface functionality of a CSS on ACE 4710 but have problem with it being treated as a general routed interface.
 
Scenario
On ACE 4710 I have a front-end interface for client facing VIPS and a back-end interface facing a server farm, taking care of load balancing flows
 
Non load-balance system traffic for the back-end servers also flows through these two ACE interfaces, following a default route path (the back-ends use the ACE as default gateway) i.e. dns requests from the servers flow through the ACE egressing the front-end interface to hit a firewall and route to an internal dns server.
 
Issue
If I add a "management interface" to the ACE 4710 and give it an IP address for management access, the interface by default assumes 'routed' mode and as the ACE treats this as a general interface it will route traffic out of it. For example if the IP address of this management interface is on the same network as the internal dns server, it breaks that connectivity. This as the ACE will see the "management" interface as best route to directly connected network and send traffic to dns server over that, however dns server response traffic will follow its defult route path via firewall and ACE front-end interface to get reply to back-end server. The firewall will block this traffic as traffic is asymmetrically routed and firewall not seen the initial dns request packet.
 
Question
Is there a way of making an ACE interface a 'non routed' management only interface for out of band management use? That is ACE will not attempt to route general traffic through the interface
 
I realise I could achieve this with multiple contexts but want to have a single context for various reasons - i.e. to have a kind of like for like CSS replacement using ACE 4710

Cisco Application :: ACE 4710 And HA On Stackable 3750

Nov 8, 2011

I am running 4.2.1a and my topology is one subnet only so using one-arm thereby management svi, VIP, ft interface, and host server are all on same subnet.
 
With above scenario, is the ACE 4710 HA support on 3750 stack?
 
On 3750, I use port channel 10. Likwise channel 10 is config on both ACE and HA WILL NOT WORK
 
On 3750, I then use port channel 10 and 11. Thereby, channel 10 is on primary ACE and channel 11 on standby ACE and it works but with following observation:
 
-  standby ACE is configured channel 11 and it syncs up but replace 11 with channel 10 then shutdown 10 and all interface has "channel-mode 11" removed. I have to put "channel-mode 10" on each interface instead of 11 and then unshut the "inter port-channel 10" - then add "ft-port vlan xxx" to get it to work
 
- standby ACE has "switch/admin" default hostname but I expect after sync that it would have the hostname I defined "ACE-COLO/Admin" instead
 
Looking for other discrepency as this is my lab environment before I implement into production as to decrease downtime.
