I recently "inherited" a CSS 11503 - I've only used ACEs before - and I want to get HTTP keepalives working.To start, I created a test service:
lb-1# show run service sunbird-http-7025-test
!************************** SERVICE **************************
service sunbird-http-7025-test
port 7025
ip address 141.211.229.168
[code].....
I need to configure a keepalive that check an url in a server (http in port 9500 not in port 80) and check the port 443 in the same server. If any of them not response . the service should go down.
View 1 Replies View RelatedI have a number of web sites that are currently being load balanced by CSS 11503s runninng 8x code. I was recently requested to configure HTTP --> HTTPS redirects on the CSS for every site. In the past, I have only configured the redirects for sites that had a requirement. Now it appears that the server teams want all content encrypted.
1) What impact will this have on the CPU?
2) What impact will this have on Memory utilization?
3) Is there a maximum nubmer on redirects?
4) Are there other things I should be concerned about?
I'm trying to design a CSS configuration that allows servers in the same vlan to be the source and destination of load-balanced traffic. My thought is to add two new vlans, one for the VIPs and one for the servers, then NAT the source IPs going from the LB to the servers.
Is this the right way to do it?I've never NATted using CSSs, so I wanted to verify what I'm thinking.Our current config trunks the vlans -
interface 1/1
trunk
vlan 1
default-vlan
vlan 555

I have already raised this discussion on "LAN, Switching and Routing" group. But I guess this is the right group for my queries. So I am sending my queries in this group again.
We are using CSS 11503 with one 16FE line card. We have connected 3 servers with redundant link. So FE1-2 in Server1, FE 3-4 in Server2 and FE5-6 in Server3. Our system team has configured APA in their servers as they are using HP-Ux.
1) Do we need to do any configuration at line card.
2) Do we need to do ether-channel at loadbalancer end. if yes, can you share me any cisco doc on how to do it.
I have a WRVS4400N router in a remote office. I have connectivity to the office and computers there. But the web interface for the router is failing to come up. This happens once every few days or so. Is there any utility or something that I can use to remotely reset the router without making use of the webinterface or having physical access to the router?
View 4 Replies View RelatedWe 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.
I've got an issue with a CSS 11501 where, if *any* change is made to a global keepalive (active), the device reboots. The code is 08.10.2.05. I'm unable to search the TAC archive or I would've gone there first.

I have a request from an application group where I have 3 rserver in the server farm but they want all traffic to only go to the first server unless that server fails. If the first server fails, only then do they want traffic to go to the 2nd server instead and if that fails, then traffic goes to the 3rd.
I've read through the documentation but haven't figured out a way to do this. What to do this type of failover configuration?

We had an incident in our network where a layer 2 loop caused some high traffic through the CSS' and had to shutdown some network gear(including the CSS) to clear the problem. When the CSS' were powered back up, the SSL service was suspended, why this would occur? There rest of the config appeared normal. I am the only person on these boxes, the configs were written, and I have never had a reason to suspend the ssl service.

View 2 Replies View RelatedWe have several pairs of CSS11501 and 11503 in our network.This issue affects only one pair of CSS11503 in one of our data centres. [code] We use vrrp in one-armed mode for load balancing and they units have performed great for a number of years. We're obviously going to be migrating to ACE ... but not just yet.We have started to experience a problem with replicating the configurations between two CSS11503 in a pair.When running the commit-VipRedundConfig, it starts off happily enough, though slowly.Ending with "working" and the spinning cursor, even after 1 hour the script hasn't completed.We noted on the backup CSS that the APP configuration disappears during the process and I can't remember if this is normal behaviour.
Re-adding the app session configuration seems to interrupt the process, and when checking the configuration on the backup CSS approximately half of it is missing. Everything after the first owner is gone.
1. Configuration is too large, or just large enough to make the commit script take too long for realistic service.
2. Software bug?
3. Combination of both.
4. From now on manually add config to both CSS's and maintain it by process management.
I only have configured load balancing on apache with a very simple setup. I have to deploy 2 applications on my clients environment that run inside jboss. One of these applications needs session to be sticky to work properly. The other does not.
In apache I can configure is the sticky parameter is true or false, based on the url, like /appA/* is sticky and /appB/* is not sticky. Can I do that in a CSS 11503? My client insists that it is impossible. That the CSS is only ip based.
I copied the configuration below from the manual: owner arrowpoint # content ruleWapSticky

View 3 Replies View RelatedI currently have a content group as follows;
content My_Group
add service blade1
add service blade2
add service blade3
vip address 1.2.3.4
advanced-balance arrowpoint-cookie
[code]...
So I have 3 blades which are proxy servers and user go first to an MS ISA server then the VIP of the CSS and then the rules processes them give them a blade and chuck them out onto the Internet.
I want to leave the above rule, but remove one blade create an additional content group with that blade and have it process requests for a particular site so, I would create the following
content My_Group2
add service blade3
vip address 1.2.3.4
advanced-balance arrowpoint-cookie
[code]...
So my question is can I do that having the same VIP's etc so if a request comes in and it matches www.thewebsite.com that the second content rule matches it 'better' and therefore processes it or would it still be caught by the "/*" content group. I don't want to create more VIPS as I have a real ache getting firewall rules done.
I'm not sure if my terminology is correct when using hairpinning but i was wondering if there is any special config needed when you try to access a content rule VIP from a server that's configured as a member of a source group on the same CSS?
So say i have a content rule with a VIP 20.20.20.20 and i also have two servers 192.168.1.1 and 192.168.1.2 that are part of a source group with VIP of 20.20.20.21. My problem at the moment is if from the servers 192.168.1.x i try to ping the other VIP 20.20.20.20 that's configured on the same CSS then it doesn't work and ping fails. The same happens with HTTP traffic to the 20.20.20.20 VIP.
I would have thought that the NAT of the source group would happen before the routing so the 192.168.1.x IP's would be natted to 20.20.20.21 and then passed over for routing where the CSS would see that the VIP 20.20.20.20 is local and it would send it on it's way.
I thought it might be ACL related but i increased the verbosity of acl logging and couldn't see anything in the logs.The source group works fine on it's own and from the CSS itself i can ping the 20.20.20.20 VIP fine. It just seems that from the source group members i can't ping the VIP.
what is the OID for See the hit status of the spefic VIP and RIP coming under the VIP .apeart from this CSS box having any module to moniter the hit status or VIP's and RIP's
View 2 Replies View RelatedI have a CSS 11503 with a basic content rule for TCP 10000 going to a few backend servers. I was looking into the default timeout values for flows and when testing using telnet the flow didn't terminate as expected?
For example, i have no 'timeout multiplier' specified in the config and when i look at the output of 'show flow-timeout default' it tells me the default 16 seconds timeout is in effect for *. With that in mind, i telnet to the content rule vip on TCP 10000 and on the backend server using wireshark i can see the TCP threeway handshake. With no data passing i'd expect the CSS to terminate this flow after 16 seconds.. yet it takes exactly 128 seconds before wireshark shows the RST and the flow is terminated. 128 being 8 times the default 16 second flow timeout.
If i try to force the connection to close early by specifiying 'flow-timeout-multiplier 2' in the content rule, or even a multiplier of 40, it still waits 128 seconds to close the telnet connection.
Is it possible on the CSS11503 to create a layer 5 content rule that matches a url "/*/_edit".
View 3 Replies View RelatedWe have a pair of CSS 11503 installed in our DC. Stickiness is configured for one of the application since long back and was working pretty fine till last couple of months. Since last two months, we observed that CSS is not distributing sessions the way it suppose to be. Mostly, it forwards the session to same server even though request is coming from different sources. Once we refresh the sessions manually, it starts working fine. We have to do this exercise manually every alternate day.

For a CSS with a SSL module (performing SSL termination) - is it possible to impliment a redirect on https URL to send to equivalent http URL.If my understanding is correct, the CSS will do SSL termination and then use an http content rule on the resultant http stream as it is recursively handled by the CSS ? This would mean that the SSL module has no way of seeing/acting on layer 5 and above data (i.e. picking up on a specific URL) and can not itself issue a redirect - i.e. you could not associate a redirect statement or service with the following ssl content rule ? [code]The CSS would instead rely on a http content rule to impliment a redirect - i.e. you would have to associate a redirect statement or service to the following http content rule instead?
But if the CSS is already handling traffic for existing url... traffic that is going to cause a loop when a client goes direct to. url...I realise the requirment is uncommon / a bit convoluted, its one of those don't ask type scenarios - aimed at achieving a specific requirement.Would the ACE 4710 be able to handle such a scenario any differently ?
