ACE 4710 Long Timeout

I have a redundant set of ACE4710's and if a user is connected to a particular host behind the LB's and I take that host manually out of service via the LB the client is unable to reconnect to one of the oter servers serving the same application for some time (approx 2-5 minutes). Is there a way to expidite this so as soon as a host is taken online the other hosts will take up future connections from the client?
Thank you in advance,
Matt

From : http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A1/configuration/slb/guide/rsfarms.html#wp999576
The no inservice command instructs the ACE to do the following:
•Tear down existing non-TCP connections to the server
•Allow existing TCP connections to complete before taking the server out of service
•Disallow any new connections to the server

ACE 4710 - show stats connection questions

Hi,
I have three questions regarding the "show stats connection" command in the ACE 4710:
1. What is the criteria for a connection to be added to the "Total Connections Failed" counter?
2. What is the criteria for a connection to be added to the "Total Connections Timed-out" counter?
3. Is there a command to get more information why the connection was failed or timed-out (e.g. to/from which IP, url accessed etc.)?
Thanks in advance for your help!
Best regards,
Harry

Harry,
a connection failed if the server did not respond or resonded with a RST.
As long as the connection gets establised, it is counted as a success.
The connection timeout counter is incremented when the connection is idle for the configured timeout value or for L7 connections if it does not complete the 3-way handshale within the embryonic timeout interval.
Since this is clear why those counters are incrementing, the only way to get more information is to capture a sniffer trace to verify if the conditions above are met.
Gilles.

ACE 4710 in bridge mode not working

I am trying to configure ACE 4710 bridge mode and I am stuck up in physical interface configuration. I have configured gig1/2 of ACE as trunk port and on layer 2 switch I have assigned that interface (gig1/2) to VLAN 11. I tried trunk port also but it got disabled due to BPDU error.
I am not able to ping servers as well as gateway. Below are the topology and context configuration:

ACE     (int gig1/2)

" I tried trunk port also but it got disabled"   <----- if your L2 config is not correct, nothing will work.
What is the setup on the switch ? Trunk or access vlan ?
What is the status of the interface ? up ? down ?
Do you see something in your arp table ?

ACE 4710 HTTP Probes

Using the ACE 4710 for loadbalancing a Sharepoint site.
We currently have a HTTP probe setup to check the port 80 status of the rserver.
Is there anyway to get the HTTP probe to check a DNS entry for each of the application sites? For instance http://info vs http://site are two different web sites running on the same IP. One site could have a problem but the actual port 80 for the IP may be still alive.
Thanks for any information.

Has anyone figure this out? I am tring to get healthchecks/probes setup in this same fashion. I have 2 servers with 1 IP but have many sites. I want to probe each side and ensure I get a 200 code. I also have to provide credentials to the site. It seems that if i open IE I can log in just fine to the site with the credentials. However there is an active x control box that is wanting to be installed. When I set this up on my ACE it seems I am getting a http 401 unauthorized error. I have done a wireshark capture while I was browsing and I see the 401 however it also reports a 200 code after that. Do you think this is a problem because of the active x control wanting to be downloaded? Or is this an issue with the first http code that is recieved by the probe, that being the 401 and then the 200? Below is my config (cleaned of course).

ACE 4710 - Internet Explorer cannot display the webpage randomly

We have a ACE 4710 with a basic config, (see below).
When clicking on a tab from a window within Interent explorer we occasionally get an issue with it returning: "Internet Explorer cannot display the webpage" The details show "Access is denied" accessing a particular line of a javascript file.
We have put one web server out of service in the farm to make sure that this isn't a result of stickyness not quite working.
We have tested extensively by going directly to the web server directly without the load balancer and cannot reproduce the problem but we can produce the issue within a few minutes when going to the load balanced address.
Thanks in advance for any advice.

SIP load balancing issue with ACE 4710

SIP Load balancing Issue with ACE 4710
I have a Cisco ace 4710 with vesion Version A4(2.2). i configued simple SIP load balancing first without stickiness. without stikeiness we are having a problem because bye packet at the was not going to the same server all the time that left our port in used even though user hang up the phone. its happen randmly. i have a total 20 licenced ports and its fill out very quickly. so i dicided to use the stickiness with call-ID but still same issue. below is the config

I mean there should be one more statement-
class-map type sip loadbalance match-any CIN_VOX_LB_SIP_POLICY
match sip header Call_ID header-value sip:
and that will be called under-
policy-map multi-match GLOBAL_DMZ_POLICY
   class CIN_VOX_SIP_L4_CLASS
    loadbalance vip inservice
    loadbalance policy CIN_VOX_LB_SIP_POLICY
    loadbalance vip icmp-reply
is that missing in your config ?

ACE 4710 Pls need help

Hi,
Pls can you help me find out where is my error in the below:
I have an ACE 4710. Also I have 2 Bluecoat Proxy SG working in proxy mode. I want the ACE to be the Load Balancer for these 2 Proxy SG. I configure the ACE as below and put the vip-address in the Internet Explorer LAN Settings but it did not work. Also I configure Policy-based Routing on the Core Switch (for any http or https traffic going through core apply set ip next-hop vip-address).

I see that you used:

Where is the nat pool on Vlan 57 ?
May be you can try to assign that and that should help.
Something like below:

Rservers initiated traffic not sourcing the traffic as VIP in Ace 4710

One of the feature of our application is that our Application Server initiate text message to our devices sourcing from UDP 1120 and device need to see the message come from a specific pubic IP (2.2.2.2) with UDP port 1120 and reply back with the same Public IP (2.2.2.2) with UDP port 1120.The problem is we can make that happen if we have only one server in our ACE Serverfarm when we do a SNAT the real servers with the VIP address (10.1.246.32) but it does not work when we have more than one server in the Serverfarm. Since we have 2 servers, i cannot nat the real servers with the VIP address, if I do a PAT, obviously it is changing the source port of the request.
Note: This setup is working fine with the Cisco Content Switch module running on chasis 6509. When I sniff the traffic initiated from the server coming the CSM load balancer, it is sourcing the traffic as the VIP and the source port remains the same by default but this is not the case with ACE 4710
Traffic flow as follows

I see in CSS, they are able to nat the source ip address with VIP and port-mapping diabled. How do I implement
portmap disable in ACE 4710
Disabling Port Mapping
By default, the CSS NATs source IP addresses and PATs source ports for a configured source group. If you configure the portmap disablecommand in a source group, the CSS performs NAT on the source IP addresses but does not perform PAT on the source ports of UDP traffic that matches on that source group.
For UDP applications with high-numbered assigned ports (for example, SIP and WAP), we recommend that you preserve those port numbers by configuring destination services in source groups instead of using the portmap disable command. Destination services cause the CSS to NAT the client source ports, but not the destination ports. For information about configuring destination services,

Access Server through VIP (ACE 4710) but very slow

Re: Access Server through VIP (ACE 4710) but very slow
Hi Shiva
Kindly Help .....Accessing the server very slow.., Plz check my real configuration... this configuration is for application server and after this i have to configure more serverfarm for different server like webmail etc. in this ACE 4710. I have only one ACE 4710 .

Hi Shiva,
plz guide i'm new with ACE LB, also find my n/w design for connected ace to server. but server accessing very very slow, but when i connect through my old server software LB (with two interface)then accessing very fast. I just replace my old serverLB(with two interface) to ACE4710 and connect the same scenario then why not server accessing smoothly with VIP .Reply soon only I connect ACE's two interface with switch.....

Prem

Xchange 2010 and ACE 4710

Currently testing our new xchange servers behind our ACE 4710 in qa..
I have 2 xchange servers in 1 server farm behind the ACE. No SSL being used.
All seems to be working thru the mapi client, but the OWA web connection seems to be timing out quickly.
Any ideas on what could be causing this timeout ?
Do I have to configure a timeout period for these connections ?
Any help would be appreciated.
Cheers
Dave

can you share your config ?

Need help to Configure Cisco ACE 4710 Cluster Deployment

Dear Experts,
I'm newbie for Cisco ACE 4710, and still I'm in learning stage. Meanwhile I got chance at my work place to deploy a Cisco ACE 4710 cluster which should load balance the traffic between two Application Servers based on HTTP and HTTPS traffic. So I was looking for good deployment guide in Cisco SBA knowledge base then finall found this guide.
http://www.cisco.com/en/US/docs/solutions/SBA/February2013/Cisco_SBA_DC_AdvancedServer-LoadBalancingDeploymentGuide-Feb2013.pdf
This guide totally fine with my required deployment model. I have same deployment environment as this guide contains with ACE cluster that connects to two Cisco 3750X (Stack) switches. But I have some confusion places in this guide
This guide follow the "One-armed mode" as a deployment method. But when I go through it further I have noticed that they have configured server VLAN as a 10.4.49.0/24 (all servers reside in it) and Client side VIP also in same VLAN which is 10.4.49.100/24 (even NAT pool also).
My confusion is, as I have learned about Cisco ACE 4710 one-armed mode deployment method, it should has two VLAN segments, one for Client side which client request come and hit the VIP and then second one for Server side. which means besically two VLANs. So please be kind enough to go through above document then tell me where is wrong, what shoud I need to do for the best. Please this is an urgent, so need your help quickly.
Thanks....!

Dear Kanwal,
I need quick help for you. Following are the Application LB requirements which I received from my clinet side.
Following detail required for configuring Oracle EBS Apps tier on HA:
LBR IP and Name required to configure EBS APPS Tier (i.e, ap1ebs & ap2ebs nodes)
Suggested IP and Name for LBR:
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm detail for LBR Setup
Following detail will be use for configuring the LBR:
LBR IP and Name :
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm Detail for LBR setup:
Server 1 (EBS App1 Node, ap1ebs):
IP : 172.25.45.19
Server Name: ap1ebs.xxxx.lk [ap1ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Server 2 (EBS App2 Node, ap2ebs):
IP : 172.25.45.20
Server Name: ap2ebs.xxxx.lk [ap2ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Since my client needs to access URL ebiz.xxxx.lk which should be resolved by IP 172.25.45.21 (virtual IP) via http (80) before they deploy the app on the two servers I just ran web service on both servers (Linux) and was trying to access http://172.25.45.21 it was working fine and gave me index.html page. Now after my client has deployed the application then when he tries to access the page http://172.25.45.21 he cannot see his main login page. But still my testing web servers are there on both servers when I type http://172.25.45.21 it will get index.html page, but not my client web login page. What can I do for this ?
Following are my latest config :

Cannot Telnet to ACE 4710 after upgrade to A4(2.3)

I have a pair of ACE 4710s with 12 contexts sharing the load, running A4(2.1). Yesterday I upgraded one of them to A4(2.3)
now I cannot telnet to the Admin context.Pings ok. I can telnet to other contexts on the box and everything seems to be working ok
when i do a " sh telnet"
comes back with
No Session Information is available
sh telnet maxsessions
telnet maxsessions 16
Can anybody help?

further this post, it was not a resource problem as had allocated 5% for the Admin context.
I up graded IOS Saturday evening, could not Telnet in, tried again on Sunday same result,
though this morning (Monday) Can now telnet in ok very strange
I was connecting via the AUX line of a 2851 router to the console port.
whe I disconnected this morning I saw the following message
INIT: id "T0" respawning too fast : disabled for 5 minutes
not sure if this is a 2851 message or an ACE message, but after getting that message is when I was able to Telnet in
was it a coincidence
anybody any ideas

ACE 4710: Possible to allow a user to clear counters but nothing else?

Hello all,
Using an ACE 4710 we have a user setup with the Network-Monitor role which allows the user to view config, interface status, etc. We would also like to allow this user to clear the interface error counters as well, but nothing else. Is this possible?
Thanks!

Hello Brandon-
Network-Monitor only lets you browse outputs, it is a not a role that allows a user to make any changes including clearing stats. You can create custom roles and domains to get closer to what you want, but you cannot zero in on a single command like that.
i.e.
ACE# conif t
ACE(config)# role MyRole
ACE(config-role)# rule 1 permit modify feature ?
AAA             AAA related commands
access-list     ACL related commands
connection      TCP/UDP related commands
fault-tolerant Fault tolerance related commands
inspect         Appln inspection related commands
interface       Interface related commands
loadbalance     Loadbalancing policy and class commands
pki             PKI related commands
probe           Health probe related commands
rserver         Real server related commands
serverfarm      Serverfarm related commands
ssl             SSL related commands
sticky          Sticky related commands
vip             Virtual server related commands
You can create a permit or deny rule, within that, create/debug/modify/monitor each feature seperately.
Domains allow you to create containers for objects. You can place specific rservers, serverfarms, etc. into it - then apply it to a role so that the user assigned to it can only touch those objects.

Chris Higgins

ACE 4710. Unable to clear ssh sessions

Hi.
Once in the CLI of an ACE 4710, using the command "clear ssh session id" I am unable to clear/kill any of the remote ssh sessions established.
According to the administration guide, the "clear ssh .." command must clear the sessions, but it does not, or maybe I am missing something?

ACE 4710 and mangled HTTP requests

After replacing a Cisco CSS/SSL Accelorator and PIX firewall with an ACE 4710 to do load balancing and SSL encryption behind an ASA firewall we started seeing mangled HTTP requests in the Apache access logs for the servers in the server farm. Here is one example:
XX.XX.XXX.XXX - - [21/Oct/2012:01:42:12 -0500] "heckoutFlag=true&verifyPassword=false&newsletter=false&emailaddress=&email2=&pass1=&pass2=&username=POST /register/LServlet HTTP/1.1" 501 3322 "https://www.ourwebsite.com/register/CServlet" "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)"
Rather than appearing just after the timestamp, the "POST /register/LServlet" is tacked on to header information that shouldn't even appear in the log. Also the first letter in that header information is always missing (heckoutFlag instead of checkoutFlag in this example).
The mangled request always shows up as a 501 HTTP error and shows up late in the Apache access logs (timestamp is out of chronogical order) and always appears with several duplicate POSTs:
XX.XX.XXX.XXX - - [21/Oct/2012:01:42:23 -0500] "POST /register/LServlet HTTP/1.1" 200 8537 "https://www.ourwebsite/register/CServlet" "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)"

This is occurring for several different URLs and not just the one above and for multiple web browsers.
The ACE load balances to servers running Tomcat 7 with Apache HTTP server v. 2.2.14.
A recent ACE software upgrade to A5(2.1) has not fixed the problem.
Has anyone seen this before?
Thanks for any insight you can provide.

Hi Kari,
Do you have a sample of the configuration which you got with the CSS?
What is the current configuration which you got on the ACE?
Can you shows this output: # show stats http?
