Cisco Application :: ACE 4710 - Monitoring Real Server Showing N / A?

Jun 25, 2012

I recently installed a Cisco ACE 4710 version A4(2.0) into our test network. Load balancing across a number of web servers appears to be working ok and serving pages to users. However, when i tried to check the real time stats via device manager (Monitor> virtual contexts> context > Real servers) a number of fields specifically "current connections", "total conns", "failed conns" etc were showing N/A. Do I need to enable this somehow i.e. polling, if so how?

Cisco Application :: ACE 4710 Webpage Very Slow To Load When Going To ACE

Aug 13, 2012

Experienced the same sort of behaviour with an ACE 4710 version A3 (2.5). When trying to connect to a webpage on port 443, the pages over 1 minute to download fully. I have timed the download using the plug-in firefox. What is strange is that the browser successfully makes the connection, 200OK etc,  but each 'get' takes a very long time to transfer. If I go directly to the server and don't pass via the ACE the page takes between .7 and 1 second to transfer.Is there a way to speed this transfer up, I am currently looking at connection maps.

Cisco Application :: ACE 4710 - Internet Explorer Cannot Display Webpage Randomly

Mar 20, 2013

We have a ACE 4710 with a basic config, When clicking on a tab from a window within Interent explorer we occasionally get an issue with it returning: "Internet Explorer cannot display the webpage" The details show "Access is denied" accessing a particular line of a java script file.
 
We have put one web server out of service in the farm to make sure that this isn't a result of stickyness not quite working. We have tested extensively by going directly to the web server directly without the load balancer and cannot reproduce the problem but we can produce the issue within a few minutes when going to the load balanced address.

Cisco Application :: C6500 CSM Real Server Cannot Ping Its VIP

Oct 25, 2011

I've been running into an issue with Cisco CSM for a number of years, but always found a way around it.  Im attempting to get to the bottom of this to find out once and for all, if this is infact a limitation of the device, or a config issue/work around is possible.
 
Here is my situation.  My CSM's are configured in bridging mode.  Traffic works great, traffic bridges across vlans correctly.  Everything works and have many instances of smilar configurations running in production.  Every once and a while, a client requests that a "real" server (ie LWCMW-021)
cannot ping its VIP address (10.95.88.68).  I am assuming this is related to the NAT Server, but not 100% sure.  Clients have requested this functionality for some type of application based purpose, but Im unaware if CSM in bridging mode can provide this or not.

Cisco Application :: ACE 4710 Server In Multiple Server Farms

Jul 23, 2012

I put multiple rservers in multiple server farms?
 
So for example rserver1 and rserver2 are put in serverfarm production1 and are in use with particular sticky and load balancing settings.
 
Can I then create serverfarm test_production and put both rserver1 and rserver2 in it?  Then play around with the sticky and load balancing settings as a test without affecting the production serverfarm.

Cisco Application :: ACE 4710 Take An Action When A Server Goes Down

Jun 2, 2011

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?

Cisco Application :: ACE 4710 SIP - Server Initiated Traffic?

Aug 7, 2012

I have a Cisco ACE 4710 A5(1.2). Scenario: Inbound call from PSTN to SIP Phone. Call comes into the VIP and then load balances to sip server, the server then routes the call out via WAN to the SIP phone as below:

PSTN SIP Providor >(router)> ACE4710 > sip_server(s) > ACE4710 > (router) >SIP Phone
 
Note: Router is Cisco 3925 with "ip nat service sip udp port 5060" and Port 5060 mapped to the VIP of the ACE.If I put the sip server directly behind the router it works fine. From behind the ACE:
 
If I turn on sip inspect on the VIP the call setup (INVITE) and termination (BYE) work fine but the audio loops on the PSTN side from the mic to the speaker.If I turn OFF sip inspect then the audio is fine and mapped correctly but the call terminaton (SIP BYE) hits the VIP from the PSTN but never reaches the sip server.For ease and dianostics, I have turned off all sip servers except one meaning the load-balancer has only one server to choose from.SIP Call_id sticky is setup and seems to work, though irrelevent with one server only on test.How do I get the ACE to accept 'server initiated traffic' with sip inspect so it knows about the pending BYE when it comes back from the IP phone via the VIP?Config below, image attached. Bridged mode (also get the same result in routed mode)
 
access-list everyone line 8 extended permit ip any anyaccess-list everyone line 16 extended permit icmp any any

Cisco Application :: Unable To Access Server Through VIP (ACE 4710)

Oct 3, 2012

configure Cisco Ace 4710 ?Note :- Just a testing face I need to access my one server(192.168.1.11 : 80) through VIP :- 10.13.77.10 ,    I have only one Cisco Router 2800 and One L2 Cisco Switch 2960 and Cisco Ace 4710 . So I already configured 2 Different VLANS in Switch (Vlan 10 & Vlan 100) and by router I given the ip address of that Vlans with Inter Routing Vlan. My Connectivity is like this :-- Router Ethernet 0/0 --- 10.13.77.1/24 with vlan 10) & Router Ethernet 0/1 ---- 192.168.1.1/24 with vlan 100 ) connected with switch after that I configured ACE LB and connect the ACE interface with switch Like that ---- Connect to ACE Interface 2/3 vlan10 with switch vlan10(Ethernet port  2-12) and  Connect to ACE Interface 3/3 vlan100 with switch vlan100(Ethernet port  13-24) .Testing to access server from Switch Vlan10 to Vlan 100 where my server is there.
 
Configuration :---

ACE>  client side Vlan10 (10.13.77.4/24) , VIP :- 10.13.77.10, SM-- 255.255.255.255
 ACE>  server side Vlan100 (192.168.1.5/24), Web server -- 192.168.1.11 with 80 port
 ACE> Managment Vlan 1000 (172.16.6.5/24) ,
 ip  route 0.0.0.0 0.0.0.0 10.13.77.1
 
 I already Configured in Routed mode but From Vlan10 ip subnet example like 10.13.77.12(Client or User PC) tried to access server 192.168.1.11 with VIP http://10.13.77.10 but not responding , if i access server with real IP then accessible (why boz there is inter vlan routing)?

Nov 2, 2011

We are using a sticky serverfarm with 2 real servers, one server was down for maintenance for an extended period of time. When it came inservice again it was not getting any connections. is it because all the connections had stuck to the other server ?  we want sessions to be sticky but we also want to LB?I got it working by bouncing the server that had been online all the time. things started to LB then.BTW  the ACE 4710 is running 4.2.1

Cisco Application :: ACE 4710 No Access To Any Server To Do File Transfer

Jan 26, 2013

I ma having issues trying to import a .PEM file into an ACE 4710. The original file was a PCKS12 file that was converted to a set of .PEM files as I have no access to any server to do a file transfer. This has worked in the past. the error I get is "Error: File not of recognized types - PEM, DER or PKCS12, import failed". I am not sure what is exactly failing. The cert was converted to a .PEM and the ACE imported that fine.

Cisco Application :: ACE 4710 - Configuring Backend Server Monitoring?

Apr 6, 2013

Currently running an ACE 4710, which is handling all of our inbound SSL connections and then forwarding requests thru to backend web servers. This all works fine.
 
My question is this..Right now we are not load balancing any of the backen web servers. But I now have a requirement that should a web server crash or become unavailable I need to redirect that backend connection to another web server.
 
Scenario is more like I have 2 web servers both serving same content, but I want one server to take all the connections unless it fails, at that point have all the connections forwarded to 2nd server.Is there a way to setup the load balancing where the 1st server gets all the connections until a failure happens ?

Cisco Application :: ACE 4710 Load Balance Only If Primary Server Fails

Oct 14, 2012

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?

Cisco Application :: ACE 4710 Prevent Failback To Primary Server When Probe Fail

Feb 26, 2011

I want to configure my ACE so that if a probe fails, it fails over to the backup rserver, BUT it won't failback to the primary rserver until manual intervention is complete. The problem is we don't want an rserver to fail and failover to secondary, then failback to primary, repeat... (flip-flopping).   I want to be able to have time to get on the server and find out what may have caused the probes to fail before it fails back.

Cisco Firewall :: ASA 5510 Real Time Logs Showing Incorrect Ports

Oct 17, 2012

I have an issue on an ASA 5510 that I have noticed today, when I am using the log viewer all of the information recorded only shows the high end source and destination ports.  For example
 
Source IP 10.10.4.69
Source Port 59886
 
Destination IP 8.8.8.8
Destination Port 59866
 
So what seems to be happening is that I am seeing only half of the connection in the log viewer, I see the side with the high end ports and not the side with the ports the application uses, this example was done with a ping. All my services are working correctly and the client sending the ping gets the response expected, it just seems I have lost the logging display?

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.

Cisco Application :: ACE 4710 Lic Performance

Mar 19, 2012

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
 
 or
 
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
