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.
Why do my connection not clear when my service goes to a down state. The only way I can get the connections to clear is by bouncing my content rule. CSS11503 version 08.20.4.05s - SSL all the way to the server --- I also have flow permanent port3 443 configured, but I don't understand why the other two servers go to zero while server01 never goes to zero. If I remove the flow permanent port3 all the counters go to zero, but I would think if the servers goes down then the connections should go to zero regardless of the flow permanent port configuration. [code]
I know that it's possible on the CSS to handle multiple incoming HTTP requests that terminate on the same IP address and port and balance them to various servers based on the url. For instance, I can set up URL at the same 192.168.35.12 address in DNS, and set up two different content rules:
content cats vip address 192.168.35.12 port 80 url "//www.cats.com/*" add server cats1 add server cats2 active
content dogs vip 192.168.35.12 port 80 url "//www.dogs.com/*" add server dogs1 add server dogs2 active.
Easy and straightforward.
But what if I want to add SSL handling for URl. I'm not sure how to create the ssl-proxy-list where one content rule (ip address/port) combination needs to pass through the ssl module and get matched with the proper ssl certificate.
Can this be done? Can one associate multiple certs and keys with a single ssl-server entry and a single ssl accelerator service? Or do I have to create multiple ssl-proxy-lists for cats and dogs and build multiple ssl services each referring to a unique ssl-proxy-list, and then use the url parameter in the https content rule to determine which ssl service (and therefore which key/cert pair) gets the traffic?
This is a newbie question regarding CSS11500 series loadbalancers as I trying to get up to speed with managing them as part of my job. I noticed that there are a couple of CSS "clustered together" since I see they are managed using a single ip address.
My question is around how to establish a session to each individual device in this cluster, if at all possible? If is not possible, how do manage the secondary device in this cluster to perform tasks such as copying new software to it, backing it up, etc.?
In my lab I have only one ESX server. On this server I am running VSM and vCenter (appliance).I am trying to get 1000v working however everytime I try to migrate my ports I get the following error:Network configuration change disconnected the host '192.168.0.10' from vCenter server and has been rolled back.fault.NetworkDisruptedAndConfigRolledBack.summaryIt seems that it doesn't like the fact that vCenter lives on the same ESX host as I'm trying to migrate. How I could get this to work?
I have a single cisco 11503 load balancer.There is a single Banner student information system which is load balanced on it with Virtual ip 10.3.20.101 which is working fine without any issues .I am now trying to add an Oracle ERP application with virtual IP 10.3.20.230 and physical ips 10.3.19.22 and 10.3.19.23 all on port 8003.When I just make the group ERP-Apps-Grp active , the vitual ip address 10.3.20.230 is pingable , but when I make the the content Erp_IAT active it stops pinging.

How can i change AP host name for LAP via CLI? I got the error 'command is disabled' when i try to use command 'capwap ap hostname <>'
I try to disconnect LAP from WLC, factory default, clear all private-configure and clear all files in nvram: but not working (still got error). I cannot change via WLC GUI for CAP2602I series. I don't know why.
I checked bug CSCsy17745 but current in use software is fixed.
I want to deploy a high availability solution for web servers in two data centers. In the primary data center I have deployed a group of web server and I want two deploy additional servers in a secondary data center for disaster recovery and high availability. Reviewing the documentation, looks like the GSS4492 is the solution for my company needs but I am not sure if I have to implement just the GSS or if I need a ACE4700 integrated with the GSS?.
I have a GSS 4490 but only want it to be authoratative for certain hosts. Sysadmins don't want to lose control of their DNS records.How do I point active directory to the GSS to look up the host?I need to keep the AD domain as authorative for the DNS records, but to pass on DNS requests to the GSS for certain hosts.
The below is the display that I get on the screen when i boot the device.There are two error's one is when the daughter card is found and device give us login access after which it reboot’s. The second is stated below (this is a screen copy of the error)

I'm working on a small scale Cisco WAAS deployment. I want to know if it's possible to use the entry level Cisco WAVE-294-K9 as Central Manager.Also about licensing, does this appliance model come with the enterprise level license
Do you know if it is possible in ACE 4710 appliance to configure a SIP TLS ?The SIP probe we have in the configuration guide it is only for clear text. for Lync 2013 we need to establish first a TLS session and then within it, send an SIP request..IS it possible in any version? I tried also to configure a HTTPS probe but it fails as it sends a GET which the Lync SIP server doesn't understand.
I want to use the ACE blade in CAT6500 to loadbalancing SYSLOG events towards (SIEM) collectors. Servers and network devices will sent there syslog messages to different collectors after being loadbalanced by ACE. I was just wondering, since a lot of clients are going to sent there complete syslog events to the VIP and thus introducing a high connection rate. (+/- 200.000 CPS) According to the specs, the ACE blade has a limitation of 325.000 connection per second. I suppose this is a limitation at device level. (not on a per context basis, and does that include both TCP and UDP packets?) Could the UDP BOOST feature might come in handy allowing very high rate UDP syslog packet loadbalancing?
We are evaluating the one-arm design for the ACE 4700 and need some clarifications:
1. Are there any limitations in the one-arm design and the SSL offloading
2. Can the ACE be configured with an IN and an OUT vlan to the router
CLIENT -> Router -> ACE IN -> ACE OUT -> Router -> Server Vlan
so that the SSL and the clear text traffic is in a separate Vlan?
3. In some sample configuration i saw SNAT configuration on the ACE to modify the client IP. This i assume is for instructing the return traffic from the server to go through ACE? Using SNAT we eliminate the requirement for NAT or PBR on the router? Will i still be able to insert the client IP address after the SSL offload?
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.
One of our ACE-20's crash recently with little info as to why - fortunately it was the FT standby module so service wasn't impacted but obviously keen to determine the cause of the crash, and potential resolution.
Running A2 (3.5).

I need to setup new ACE 4710 device , after referring to "Establishing a Console Connection on the ACE" i had managed to set up initial console connection. During installtion i had configured vlan (default vlan 1000) , interface ip adess& subnet mask.
Post initial config i understand i should be able to open' Device Manager GUI Login Window' but it is not opening.I also need inputs on setting 4710 for the telnet connection
We have a CSS11503 that is currently being used to accept incoming HTTPS and SSH connections on a specific VIP and then PAT those client connections. I understand that it also PATs the server initiated connections. [code]
ACE A2(3.4). Is it possible to set a rate-limit connections per sec from any source IP. For example, if a client is trying to GET a web page 10 time per sec I will send a reset or drop that connection.
How do I apply the connection parameter map in a configuration like this to the service policy int827? Do I need to define the traffic? Can I specify only one source destination flow to apply the set tcp half-closed TCP normalization against?

For server load balancing, does the ACE4710 support custom protocols? We'll be using HTTP for server health monitoring, and to determine if a server is up or down. But the client/server application is custom, and includes a lot of non-standard ports. Can the server VIP handle generic TCP connections? For example client1 connects to the VIP on http, but then later client1 switches to using tcp842 (a custom protocol, not http).
I am configuring a load balancer from cisco, a ACE 4710.Load blancing is completely new to me, and i am unexpereinced in this field. It has to be configured for a customer that want to load balance HTTP and RTSP traffic over 4 application servers (Back-end),I searched alot on google for possible solutions, and got RTSP in some way to work, but http wont work says my customer.
