Cisco Application :: ANM 4.2 Fails To Add ACE20-MOD
Jun 2, 2011
I have been trying to addACE20-MOD-K9 in ANM 4.2 (0) but when I try to import it times out and I get
""Failed to import ACE configuration: Device discovery failed: Connection timed out.""
I have double-checked credentialn and access rules on the module and they seem OK. I am trying to add the module with the Admin credentials and ssh/telnet access is permited.
Is this the right way or I'm missing something. Module version is A2(3.2a)

Everytime I make a config change to one of the contexts on our ACE20, I get this message: Config Application in Progress. This command is queued to the system
If I run show download info, I get:
context : context1
Interface Download-status
--------------------------------------------------------------
187 In Progress
199 Pending
Regex download optimization status : Couldn't get status[TNRPC Timed out]
It eventually seems to complete, but it takes a very, very long time. We are running Version A2(3.5) [build 3.0(0)A2(3.5)].

I want to route gre traffic through an ACE20, but it doesn't seem to work. The only thing I configured was an ACL with gre enabled, but the ACE20 seems to drop the gre packtes. The gre traffic is entering via the vlan 561 interface and should be send out via the vlan 472 interface. Source 10.94.32.212, destination 10.94.132.39. The tunnel control traffic on port tcp/1723 is working fine. In the service-policies is nothing configured for the gre traffic.

We are using an ACE engine module(ACE20-MOD-K9) provide loading balancing service for two WEB servers and configured cookie for stickness. Below is the current configuration and it seems working fine now.
The problem I was facing is before use parameter-map change the http header length to 8k the stickness doesn't really working properly. User complains that their working session constantly be kicked out and redirect them to login page. By tracing traffic from a client we found that sometime ACE fails or stop insert the configured cookie, after increase the header length ACE start getting work.
how does the header length setup effect ACE to insert a cookie? Will the cookie insert attmpt fail if the header is longer then the maximum length configured on ACE? [code]

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

I have a ACE20 module with a performance of 4 Gbps. I want to upgrade the performance from 4 Gbps to 8 Gbps. Is correct the following SKU for the upgrade?
ACE30-UPG-08-K9=ACE10 or ACE20 to ACE30 Upgrade for 8 Gbps Throughput
And if i want to upgrade the performance to 16Gbps is correct the sku?
ACE30-UPG-16-K9=ACE10 or ACE20 to ACE30 Upgrade for 16 Gbps Throughput
I noticed that the price list of both codes is the same....
Is it right for the SKUs listed I get the new module with the performance ACE30 requested?

I would like to add a vlan to a second context on a pair of redundant ACE modules. As soon as I open up that shared vlan box we will expose ourselves to mac conflicts until the shared-vlan-hostid commands can be implemented and the module reloaded. Adding the commands is not a big deal but I may not be able to schedule a reload until next week. What I would like to do is confirm the mac pools in use by each module right now. My hope is that they grabbed unique pools when they last booted and a conflict will not be a concern now.

I have an ACE20-MOD-K9 with version A2_3_6a, and i am having problems in cookie persistency. the setup contains 4 servers using round-robin algorithm and cookie persistency and that receive http traffic on port 9090. I have been receiving complains that the users are getting disconnected randomly while accessing the web application through ACE. Below is part of the config, when setting the timeout of the cookie to default or something equal to hours, the disconnection/complains gets worse.

We have a pair of ACE20-MOD-K9 in Fault Tolerant mode. They are running multiple contexts and we have a problem with one particular context which is running SSL off-loading. Despite the config being identical on both (accept for the peer addresses obviously) and both having the same SSL Key and Cert files loaded on both, the configuration will not sync between them. [code] All the Crypto files are identical as I copied them from one ACE to the other.

We are currently running a ACE20 with 11 contexts. Recently we have seen that one of the contexts is being 'starved' of resources, especially Concurrent Connections, Bandwidth and Throughput.
Whilst we know how to address this situation by reallocating resources from less busy contexts, I was wondering if there was a more scientific way of looking at the resources being used and calculating the best way to allocate them across the ACE other than just looking at the 'show resource usage' and 'show resource allocated' commands?
Has Cisco or any other 3rd party developed a handy tool to monitor the the ACE resources which will possibly assist with calculating the optimum resource allocations across all contexts?

I have 2 Cat 6509-E switches in VSS configuration with 2 ACE modules. One in each Cat6k.
The ACE modules are running the following:
Software
loader: Version 12.2[120]
system: Version A2(3.2a) [build 3.0(0)A2(3.2a)]
We have only 2 contexts, the Admin and another one that we redirect traffic to WAAS equipment. The ANM soft running is only used for stats about the ACEs. It is version 5.2.
Since last week, the standby ACE module reboots on it own. It rebooted between 10 and 15 times until we had to leave the module PwrDown due to the constant reboots.
I tried to find any bug in the soft but I could not find anything related to that.

I tried to create a L7 class-map for blocking the clients with ciphes strength less than 128 in ACE20 running with Software version A2(2.3).But there were no command inside the L7 class-map called cipher for matching the cipher strength 128. Command Tried to issue was host1/Admin(config-cmap-http-lb)#match cipher less-than 128 So I want to know whether this is possible on ACE 20 and SW version A2(2.3). Kindly suggest a way to acheive this.
I have seen some other configuration using the parameter-match, But I dont know the Cipher Names which to allow. I want to drop all the connections with less than 128 bits cipher strength.

is there a way to reset/clear a particular context's configuration?
I see there is a 'wri erase' within a context, but no reload/reset - neither from the context itself nor from the Admin... puzzling...
I dont want to reload an entire blade just to clear one of the context's configs.

We are using an ACE20 module running version A2(3.2).I have a question regarding IP stickyness and the timeout parameter.I found this in the "Server load balancing configuration guide" (in a section entitled: "Configuring a Timeout for IP Address Stickiness"):
"The sticky timeout specifies the period of time that the ACE keeps (if possible) the IP address sticky information for a client connection in the sticky table after the latest client connection terminates. The ACE resets the sticky timer for a specific sticky-table entry each time that the module opens a new connection or receives a new HTTP GET on an existing connection that matches that entry."
The parts in bold seem to point to the fact that the timeout is an "inactivity timeout" as the counter is reset on every new connection.The next section in the documentation is entitled: "Enabling an IP Address Sticky Timeout to Override Active Connections" and says:
"By default, the ACE ages out a sticky table entry when the timeout for that entry expires and no active connections matching that entry exist. To specify that the ACE time out IP address sticky table entries even if active connections exist after the sticky timer expires, use the timeout activeconns command."
This seems to contradict the previous statement.So my question is: is the IP stickyness timeout an "inactivity timeout" or not?

My ACE module rebooted itself and after the reboot it lost all the config and it has been booted with factory default setting.
[code]....
I would like to know the reason for the same. Is this due to firmware bug? or with the Hardware? I am bit dissatisfied that all of my config vanished without any reason after the reboot of ACE.

I've run into an interesting problem trying to migrate my production config from my redundant ACE20's (A2(3.4)) to the new ACE30's (Tried (A4(1.0) and A5(1.0)). Everything on the ACE30 is working fine with a base config, but when the restore all is run from the ACE20 backup (backup all), the SSL files are not restored and return errors. All the contexts are restored correctly, along with the startup-config, but the running config fails due to no SSL.
All the crypto certs/keys are exportable and are present in the backup .tgz file.

I have an HTTPS probe that sometime fail, sometimes does not fail.
[code]....
The probe that sometimes fails is the TEST-HTTPS. The TCP_443 probe works perfectly well.The ACE is configured in bridge mode.Is it possible to capture the PROBE traffic on the ACE side?

I have a physical server running behind the ACE module ACE20-MOD-K9. The Server has several virtual machines. One of that virtual machines, has a WEB SERVER running virtual https servers. For example, server with IP address 10.0.0.20/24, has serveral virtual HTTPs servers as of urll... So, if you nslookup the servers, they all respond with 10.0.0.20 IP address. So if I do url...goes to 10.0.0.20 and read the VIRTUAL SERVER config and replies back to the request.Now, I am trying to verify that the TCP connection (443) and the HTTPS server itself is up and running but only for the url... site and not for the other 2.The problem that I am facing is tha the HTTPS probe fails randomly. The TCP probe works fine.

During high throughput times (nightly, when backup runs) we see packet drops on the network. We think it's the ACE module that drops. We use 2 ACE 20-MOD-K9 with base licenses in a FT configuration in Layer2 Mode.Now I found an interesting statistic on the ACE: [code] How to reset this counter?

I've done a lot of ACE work over the years but this is the first time this has ever come up.
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?

I work at a hospital and one of our department uses specialized software created by Varian Medical Systems. It has been brought to my attention that one of those applications has trouble opening during the day. I had the users demonstrate the issue and from what they explained to they are supposed to be able to open the application, log in, and be presented with a list of radiology images to choose from. Unfortunately, during the day this fails often and they have to try 3 or 4 times before it actually works. It behaves differently after 4 pm, and seems to work after the 1st or 2nd time at that time of the day. According to what I've been told this has been an issue as long as they can remember.
Varian has told me that they have done a number of things on their side to rule out their software and they think it is a network issue. We used Solar winds Engineer's Tool set (specifically the Network Performance Monitor) to monitor their switch and it is reporting no errors and the utilization graphs show that the ports involved have very little utilization. The most heavily utilized port is hovering between 10 and 5 person (Fa0/40). I've included a network diagram, but basically we have 1 10/100 Cisco 3350 switch (c3550-ipservices-mz.122-25.SEB4.bin), 4 clients, and 2 servers involved. They all are connected to the same switch at A-Full/A-100mbps. Although the Network Performance Monitor doesn't show any errors or over utilizaton of the ports in the the CLI I do see 35 output buffer failures and 35 under runs on the port connected to one of the servers (Fa0/40). They were a little higher and I cleared them about two weeks ago and then rebooted the switch, because I found that it could alleviate these types of errors.
They say the software use ports 5000, 55000, 55010, and 55020. We tried a packet capture, but I didn't have enough experience/knowledge to get anything useful out of it. I also checked the event logs on the clients and servers and nothing there indicates a issue in the software. They want us to replace the switch with a gigabit switch, but we have a REALLY limited budget and I would rather not if it isn't necessary. What I could try in order to rule out the network?

I have bought and installed a 2048bit certificate from Thawte on a ACE20-MOD-K9 module. The appliance can't use it and gives the following error: "This certificate cannot be verified up to a trusted certfication authority."I have contacted Thawte about this and they suggest to install an intermediate certificate from Thawte on the module, but I can't find such a certicicate for Cisco on their site. Also I'm not sure how to go about implementing such an intermediate certificate on the ACE.

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.
