Cisco Application :: ACE 4710 Load Balancer Usage

Dec 13, 2011

We are using Cisco ACE 4710 for load balancing the servers. The predictor used is 'least connections'.Have observed the below;The number of connections for a particular server in a serverfarm is 15 in the Cisco ACE.The actual number of users in that server is 6.All the users access using the VIP.Still i couldn't understand why there is difference in the number of users in the server and the load balancer statistics.

Cisco Application :: How To Capture Packet In Load Balancer CSS11501

Jan 15, 2012

how to capture the incoming and outgoing packets on the balancer?The load balancer is connected in between the customer DCN and cisco switches 2960.The reason of capturing both incoming and outgoing packets on the balancer is to prove to our customer that there is no packet loss issue on the balancer, and it could be some issue on their DCN network.Since it is a production server, I will need to ensure that there is no impact to the incoming and outgoing traffic on the balancer and other networking equipments as well.

Cisco Application Networking :: CSS 11500 Responds For Any Port

Dec 21, 2011

We have multiple CSS 11500 clusters.  We have found that on all of them, if you try to open a session on any port to an IP address on the backend of the CSS, the CSS will complete the SYN-ACK-ACK session with the client.  This happens regardless of whether there is something on that IP address or not.
 
Coming from any IP, if I try to telnet to ANY IP on the 10.2.2.0 subnet (whether or not there is an actual server on that IP) on any port (whether or not that port is open or not), the CSS will complete the initial connection.  I have verified this using telnet to numerous ports and viewing the transaction in a packet capture.
 
Is there any way to shut this off?  This is causing some licensing issues for our security folks that use a vulnerability scanner licensed on number of IP addresses.

Cisco Application :: CSS 11500 - Accessing Virtual IP From Server Vlan

Jan 5, 2011

I have a question regarding CSS loadbalancer. Let's say there are 2 vlans in CSS:

1. Vlan 10: 10.1.1.0/24 as external interface, interface where most of the clients are coming from.

2. Vlan 20: 10.1.2.0/24 for real server vlan.
 
Virtual IP 10.1.1.10 is created in CSS on behalf of two real servers (10.1.2.11 & .12) in Vlan 20. Client from Vlan 10 can http access to 10.1.1.10 successfully.
 
In Vlan 20 there's also few clients which need to access servers via virtual IP. Vlan 20 Client PC (10.1.2.101) can ping 10.1.1.10, but can't access 10.1.1.10 http service.
 
Is there any way for CSS to forward service request coming from Server vlan to be send back to the same segment?

Can't Load Particular Website?

Sep 6, 2011

Up until a few weeks ago I was playing the beta version of the pokemon trading card game online [url]... but then for no apparent reason I could not load the webpage & every time I tried I got the same "The connection has timed out" "The server at Pok�mon Trading Card Game Online is taking too long to respond." page. I tried 3 different browsers & I tried unplugging my modem & leaving it off all night to reset it but nothing seems to work. I thought maybe the website was down but then I was able to log in at the library so I thought maybe I was banned & they blocked my IP address so I downloaded a program that hides my IP address & I was able to load the site but not play the game. Just today tho I took my laptop to school & got on wifi & played it with no problem without even using the hide my IP program. So I am absolutely stumped! This is the only web page my computer will not load & I really want to play the game again.

TP-Link Dual-Band Wireless :: Unable To Load Website Hosted Behind WDR4300 At Times?

Jan 15, 2013

Region : Canada
Model : TL-WDR4300
Hardware Version : V1
Firmware Version : 3.13.23 Build 120810 Rel.44064n
ISP : Bell Canada

We have a WDR4300 router that works well about 98% of the time. We have a static IP address from our ISP configured through PPPoE in the router and are hosting our own email and web server at local IP 192.168.1.200 behind the router. Port forwarding is enabled and working beautifully.

At some times throughout the day, any computer behind the router on our local network is unable to browse to our own website by our domain name (e.g. www.xyz.com) nor by the static IP it is attached to. We also get e-mail errors with mail client configured to use the domain name or the static IP it is attached to as the outgoing mail server. When this happens, I am still able to browse any other site on the internet without problem... just not our own. Also, I have verified that while this is happening (internal computers can access the internet but not our own website):

1) I can browse to our website just fine from a computer outside of our network (e.g. a proxy or a computer controlled remotely from my home)

2) a computer from within the office that cannot reach our website using the domain name or the static IP it is attached to can still reach the website by browsing to the local IP address of the web server (192.168.1.200)

3) the problem seems to resolve itself sometime within 45 minutes of noticing it is occurring if we do nothing. We can make the problem resolve itself sooner by restarting the router.

I have the impression that this problem MIGHT start occurring when users are downloading files from our website. Of course, if this is the case, we cannot simply restart the router to fix the problem because then we are cutting off their download.

Cisco Application :: ACE20 Load Balancing

Apr 26, 2011

I have a problem with the ACE 20 load balance
 
To start with following is our architectural request flow:

Load Balancer --> Webseal /(reverse proxy) --> HTTP Server --> Portal Server

We have Hardware Load Balancer Cisco ACE20. When we access our portal from Webseal server it works totally fine without any issue, but when we access the same application using ACE we face the following issues:

1) Some of the links on do not work. For eg: We have a link "subscribe" which points to [URL], whenever we click on this link, the request is directed to [URL] i.e homepage

2) URL redirection does not work We have some links which have a url forwarding or redirection for example when we open [URL] it forwards the requests to [URL] opendocument....., but this redirection fails and again the request is thrown to homepage i.e., [URL]

3) The response of the request and the overall portal when accessed via ACE is very sluggish and it takes 20 seconds for homepage to load, whereas the homepage loads in 4 secs when accessed via webseal.

Below is the ACE details.

Hardware Product Number: ACE20-MOD-K9  Card Index:     207  Hardware Rev:   2.3  Feature Bits:   0000 0002  Slot No. :      7  Type:           ACE
Software  loader:    Version 12.2[120]  system:    Version A2(1.4) [build 3.0(0)A2(1.4) adbuild_11:54:12-2009/03/05_/auto/adbu-rel2/rel_a2_1_4_throttle/REL_3_0_0_A2_1_4]  system image file: [LCP] disk0:c6ace-t1k9-mz.A2_1_4.bin  installed license: ACE-SEC-LIC-K9

Cisco Application :: ACE 4710 Webpage Very Slow To Load When Going To ACE

Aug 13, 2012

Experienced the same sort of behaviour with an ACE 4710 version A3 (2.5). When trying to connect to a webpage on port 443, the pages over 1 minute to download fully. I have timed the download using the plug-in firefox. What is strange is that the browser successfully makes the connection, 200OK etc,  but each 'get' takes a very long time to transfer. If I go directly to the server and don't pass via the ACE the page takes between .7 and 1 second to transfer.Is there a way to speed this transfer up, I am currently looking at connection maps.
