Hello,


I am adding ASA5520 ver 7.x to LMS3.1, It is discovered but unreachable. I configred SNMP to access the firewall and use cdp also to reach the device.

I can ping the interface of the firewall but cannot discover.


Please help me to solve this issue.


thank you

If the device is unreacable via Discovery that means the LMS server is not able to communicate with it via SNMP.  Have you verified that you can manually query this device using SNMP from the LMS server (i.e. using the SNMP Walk utility in Device Center)?

Go to Device Center and enter the IP of your ASA.  Under the Tools section, you'll see an SNMP Walk tool.  Launch it, and enter the ASA's community string.  Use a starting OID of "system".  You should get back a successful response of the system branch.  If you get a timeout, then the LMS server is not able to poll the ASA (e.g. it is blocking SNMP access from the LMS server's IP).

I will check it again tomorrow morning.

This is my firewall configuration regarding the snmp.(note only one line)

You also need a line like:


snmp-server host INTF x.x.x.x poll community abcd


Where INTF is the interface on which the LMS server is located and x.x.x.x is the IP address of the LMS server.
