Cisco LMS 4.0 Layer 2 device discover problem

Please follow the attach file for network diagram.

All devices are configured successfully. Network is running successfully. Now I am facing problem in Cisco LMS 4.0.

I have successfully installed the software and it is running smoothly. But the problem is given below:

1. I successfully add the following devices:

     Core_router1

     Core_router2

     Core_switch1

     Core_switch2

     ASA1

    But I cannot add the access layer switches. Here this access layer switches are layer 2. So I try to add this switches using CDP but because of firewall cdp does not pass through firewall I think so. Now how can I add these switches into LMS?

Can add Server into LMS?

For LMS to manage the access switches, you will have to:

  • ensure the necessary ports for network management are allowed throught the ASA. Depending on the functions you wish to exercise and the granularity of your security policy, this can be a rather long list. Please refer to the LMS port usage page (specifically the "server to device" entries) for more details.
  • add the devices manually since, as you correctly note, CDP (a layer 2 broadcast-based protocol) will not pass throught the ASA firewalls. Here is a link to the procedure.

Hope this helps.
