Cisco :: Monitoring Catalyst 3560 Health Using MIB / SNMP

May 23, 2011

I'm a C# programmer and as part of my software I need to monitor some Cisco Catalyst 3560V2 24 switches using SNMP (By reading MIB/S data).Apparently this switch supports more than 50 different MIBs.My question is which MIB/MIBS contains general health data (parameters) that may determine if the switch is OK, Degraded or Malfunctioned.

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 - 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 :: Health Probe For RDP Farm 3389

Aug 19, 2012

I have an RDP server farm that lost a disk. The RDP service was still running but users were unable to log in. I'd like to create a health probe that does maybe a combination of TCP probe for port 3389 and something that can determine if the drive that stores user profiles is available.
 
I cannot add any new service (http or ftp) to the server. Is there any way I can check SNMP mibs on the windows server or maybe WMI through TCL?

Cisco Application :: ACE4710 To Perform SSL End-to-end Configuration

May 31, 2012

I am attempting to configure an ACE4710 to perform SSL end-to-end confguration. i.e. SSL termination - load balance - SSL initiate to backend server.The configuration appears to work fine in a test lab using any old web server, however when I peform the same configuration in the production environment it does not work. It appeatrs from a capture run on the ace that the ace is reseting the tcp connections after communicating with the back end server. The main difference I can think of in this environment is that the cert and key pair the ace is using where exported from the backend server, i.e. both the ace and the backend server have the same certificates and keys. Is this allowed? how to troubleshoot why the ace resets the connection.

Cisco :: Monitoring Raid Status On SRE-910 Module In 3945 Router

Feb 7, 2013

We just recently purchased a 3945 ISR G2 router and have a SRE-910 module (with two hard drives) configured in a Raid 1.  We are running a stand-alone version of ESXi on the service module and I'm trying to figure out how to monitor the status of the Raid on the drives (along with other health issues).  SNMP has revealed nothing so far and even opening a support case for which MIB's to use has proved fruitless.  All the documents I find on monitoring the modules say to use LMS which is now Cisco Prime.  I've downloaded the trial copy, put in the SNMP settings and scanned the router.  I get device results and it shows that I have the SRE-910 module installed, but I get no other configuration / device informaiton from the module itself.
 
I tried to create a new Monitoring template using the NAM health as the base template (which I'm assuming this is the correct template).  Unfortunately, when I actually try to deploy the template against the discovered router, I get an 'Unexpected end of list' error which makes me assume I'm still doing something wrong.

Cisco Application :: PAT Limits And Monitoring - ACE 20?

Dec 14, 2011

How to confirm the PAT limit on the ACE-20s. I initially read it as 1 million (the NAT limit), however I have since read that for PAT, its 4 million as it uses the connection record information and not xlate.

I've always wondered why the xlate line under 'show resource usage' is zero. If PAT does use the connection record then this would explain why, however its confusing as when running a 'show xlate' command you do see all the current PAT entries.

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 :: Monitor TPS Value For ACE-SSL-05K-K9 Module

Sep 1, 2011

I recently installed the license ACE-SSL-05K-K9  on ACE10 with multicontext solution.The license provides 5000 Maximum number of SSL transactions per second (TPS).The customer would like to track this to find out the correct size and in the case of services https upgrade licenses.Can I do it so through particular output or it's necessary monitoring with snmp service? In the second case, can you tell me the oid string to use?
 
In case the module should receive a higher number of connections to that provided by the license, what's the issue for new https connections?

Cisco Application :: ACE 3.0 Module URI Rewriting?

We are using a Ace module running version 3.0?We do have a service which can now be reached by a url like https://www.xxx.com/yyy/ < notice the last /This is running via the Ace which terminates SSL and so on..
 
So now our client wants an url like  https://www.yyy.com . The backend realservers and place of virtual dirs on IIS stays the same.

So now /yyy/ needs to be added to the backend realserver request, so the correct virtual dir is used. Therfore I need to add this Uri towards the realserver.

Cisco Application :: ACE 30 Module Configured For 250 Context?

Mar 28, 2012

I Just deployed some of these new modules and running A4.x code. How to configure an ACE with the maximum context?
 
We run in tranparrent mode with 110 Contexts, we found that with a base config for each context(80 lines of code) this would only leave us with 7% of available RAM. The Device begins to shut down services @ 5%.  like SSH and others.
  
So, Is this even possible to configure 250 contexts and still manage the device.

Whatever a NAT is supported for ACE-20 module? I do need to convert working CSM(SLB) config to ACE configuration and I am not quite sure if the configuration below is correct. ACE module should be configured in bridge mode with two vlans - vlan 36 (client) and vlan 436 (server) - bridged with interface bvi 36. NAT on ACE configurad as "nat dynamic 1025 vlan 436" into corresponding "policy-map type loadbalance".

Cisco Application :: Keep Alive Limitations On ACE 4710 And Module

I wanted to find out how many times can I apply a healthcheck in a single context. I have 50 farms that are using the same port and instead of creating 50 different healthchecks, I want to just create 1 healthcheck for the 50 farms and apply it to each farm. I also need to know if the same limitations (whatever they may be) is the same for the 4710, ACE20 and ACE30.

Cisco Application :: 6509 - ACE Module In Bridge Mode?

May 16, 2011

We have a 6509 with an ACE module. For reasons I don't fully understand the ACE is running using a BVI in bridge mode. It has loads of secondary interfaces.

[Code]...

I can ping all of the IPs on the BVI, but only servers in Subnet 10.7.42/42 can ping out of the the layer 3 on the 6509. I have all the routes configured properly on the 6509 pointing to the ACE for these subnets. The question is though the config has been excepted, is there a limit to the number of secondary on a BVI.

Cisco Application :: ACE30 Module - Popup Windows

May 30, 2012

we use ACE30 module, ver. A4(1.0) for access to intranet application. The https connection from client is terminated on ACE module, LB algorithm is used and new SSL connection is initiated to the server. Standard operation works without problems.
 
But when user generates a .xls od .pdf report in the application, it should open in a new popup window. Problem is, that it does not (but on the server, the report is generated and stored). The PC and browser are configured fine, when accessing the application from the same PC directly (bypassing the ACE module), the popup window appears.
