Cisco Application :: ACE 4710 Active Using Virtual Partitions
Feb 14, 2012
I am completely new to the Cisco ACE devices but have been asked to look at deploying them. I have read the ACE virtual partioning paper which covers the ACE module, and it mentions the following;"In an active/active high-availability design, both the primary and backup Cisco ACE modules are active simultaneously. The active virtual partitions are distributed across both modules, such that approximately half are active on the primary module and the remaining are active on the backup module."does the same resilience model work the same using the Cisco 4710 appliances? I.e. can we split virtual partions across two physical devices thereby having an active/active scenario.
We have an ACE 4710 that has two web servers in an active/passive scenario. The issue is that if node 1 fails and node 2 takes over connections to node 2 stay active even if node 1 becomes available again. Is there are way to ensure that node one is not placed back into service if it becomes available again.
how active/passive failover shoudl be configured, so I can make sure I have it set up correctly;
I have a problem in the ACE 4710. In view of the connections of a web environment. When I view connections on Config> Operations> Real Servers, Conns column values appear very high connections (Example. 1606317769078).Already in Config> Operations> Virtual Server the number of connections appear normal. Version 4710 ACE Device manger A4 (2.1a)
Report run via Individual Web server URL’sThe report takes less than 20 minutes (average 15 minutes) to fetch and return the data. This is observed 9 out of 10 times.Report run via ACE Load Balanced URLThe report keeps on running for more than 20 minutes and never completes. The front end keeps showing report is running.The data in general when tested directly by running queries against the database (bypassing the platform) completes in 15-18 minutesThe network connectivity for each and every ports involved (Loadbalancer/Servers) have been throulgly checked.
We have an ANM Virtual Appliance, version 5.2, were we login and can go no further. This was working for fine for approximately two and half weeks. We created a backup and re-loaded the system via CLI with the same result. We logged in again via SSH and we have noted the following:
cscoanmsa/admin# sh disk temp. space 4% used (141244 of 4951688) disk: 7% used (353916 of 5935604) Internal filesystems: warning - /var is 100% used (89219000 of 89258112) cscoanmsa/admin# sh application status ANM
Is there any way to access and clean out the /var directory from the CLI. is this achieved simply via the "delete" command with the full path ?
The upgrade process for ANM virtual appliance 4.2 involves doing a backup and restore as root user. I have looked through the documentation and have even reinstalled the virtual appliance to see if the install script gives away the root password for the OS but without luck.
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. [code]
I'm trying to set up a load balancer within an OVH (hoster) infrastrcture, I've followed their instructions [URL] I'm using a RIPE block (5.135.193.xxx/28) and would like the first 8(5.135.193.xxx/29) to be used as the virtual server.vlan 2676 is the local one, and vlan 1227 is the public one.After all the config steps, none of these IPs are responding to a ping, nor a direct http request.
the full configuration is :
============================================= ssh maxsessions 1 access-list ANY line 8 extended permit icmp any any access-list ANY line 16 extended permit ip any any probe tcp PROBE_TCP passdetect interval 30
i'm looking for a recommendation for a setup guide including ft i've had a quick look a wiki and i can get basics but i'm not sure about if i need to setup additional contexts etc when i'm the only one using the appliance?
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.
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
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
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?
I am currently running A3(2.6) and evaluate the possibility of upgrading to A4(2.1). The Instal & Upgrade Guide A4(2.0) mentions that A4(2.0) does not include all features of A4(1.1). Does this apply to A4(2.1)? The Release Notes mentions a list of features merged from A4(1.1) to A4(2.1) but does not clarify if there any features not merged.
we configued An ACE 4710 with SSL termination on Oracle Aplication Server 10g (10.1.2.0.2) ,so that SSL termination is done on the ACE and HTTP reaches the Oracle Aplication Server 10g (10.1.2.0.2) then we configure the ACE to enabled client authentication with Pkcs#11 smart card token certificate and this don succfully my problem need do this client certificate authentication for only the [URL] not for all SSL proxy service how can do that.
I am in the process of configuring load balancing on ACE module but struggling to configure virtual IP address for ACE module. I'm working on ACE30 module and using software version A5 (1.2). ACE module is in slot of Catalyst 6504 switch.
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?
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?
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?
I have a pair of ACE 4710s with 12 contexts sharing the load, running A4(2.1). esterday 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
ACE# sh script code NORDICID_PROBE.Error: Called API is invalid or non-existant.Hardware is ACE-4710-K9 and software A3(2.7)The probe itself is functioning ok according to show probe detail.However show script script_name probe_name -counters all remain at zero for some reason. This wasn't the case on the previously use ACE software.To my recollection the command show script code has worked successfully before on the same ACE software. Not 100% sure though, but it definitely worked on the previous software we ran on the ACE.
We have two pairs of ACE 4710s, one pair running A3(2.4) and the other pair A3(2.0). We plan to upgarde the second pair so that they are running the same image as the first pair (we know they are not the latest, but this is the first step in a larger rollout plan, and to aid some troublshooting for a major issue we are seeing.)
I have details of the upgrade steps, but my question is with regards to the licenses which are now enforced after (2.0). We currently have the following on the first pair, but are these part of the default licenses for (2.4) or would we need to purchase these as well?
