Cisco Application :: 6509E - Standby ACE20-MOD-K9 Reboots On Its Own

Jul 15, 2012

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 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.

Cisco Application :: Cookie Insert On ACE20-MOD-K9

Nov 13, 2012

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]

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 :: Show Active Mac Pool On ACE20?

Oct 26, 2011

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.

Cisco Application :: Monitoring And Allocating Resources On ACE20-MOD-K9

May 16, 2012

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?

Cisco Application :: Weak Cipher Blocking In ACE20?

Jan 27, 2012

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.

Cisco Application :: ACE20 / Configuring Timeout For IP Address Stickiness

Jan 18, 2012

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?

Cisco Application :: ACE20 To ACE30 Migration - Restore All Not Restoring SSL

All the crypto certs/keys are exportable and are present in the backup .tgz file.

Cisco Application Networking :: ACE20-MOD-K9 HTTPS Probe Failing Randomly

May 13, 2013

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.

Cisco Application :: CAT 6509E - ACE End To End Encryption With IDSM

Aug 16, 2011

We want to provide an end to encryption service using an ACE02 in a CAT 6509E. This is covered in the ACE config guide so should be OK. The issue is that we want to include traffic inspection using an IDSM2 so we need to seperate the decrypt and encryption stages and send cleartext traffic to the IDMS2. The Security and Virtualization in the Data Center pdf page 18/19 suggests that it might be possible. The design depicted there though is only doing SSL termination, then sending the clear text onto a WAF, and onto IPS but it does say end-to-end encryption is also possible.So in essence what we want to do is have traffic from clients destined for the server farm decrypted by the ACE and sent to the IDS. We then want the traffic to return from the IDS to the ACE to be encrypted and sent onto the server farm.

Cisco Application :: Standby ACE-4710 Lost Its Configuration After Reload?

Oct 20, 2009

I have two ACE-4710 in active/standby mode, running code A3(2.2). Four contexts are configured. Both devices were functional without problem, until I reload the standby unit. After reload, the standby unit completely lost its configuration with exception of the FT vlan and the FT peer configuration in the Admin context... Both units recognized each-other and I can still ping the primary unit on the FT vlan, but nothing else. Contexts are lost and interfaces are shutdown! Nothing changed at the software level, both devices run exactly the same image and the same licences are installed (it worked well before the reload).
 
So, I decided to reconfigure the basics on the standby unit in order to trigger a config sync from the primary. And here arrives the problem : I reconfigure the FT vlan, the FT peer, I check the peer state and everything is OK.
 
Then, I try to ping the primary unit from the standby unit with success :
 
switch/Admin# ping 192.168.16.1
Pinging 192.168.16.1 with timeout = 2, count = 5, size = 100 ....
Response from 192.168.16.1 :  seq 1 time 0.000 ms
