I have a not-so newly installed LMS4.2 Linux appliance. Here is my configuration archive summary:
Config Archival Status
No. of Devices
Configuration Never Collected
So I look up a device in the Device Center, here is its Reachability Status:
Which is no different from that of a device that failed. An example of the description of those failures would read like this:
SSH: Failed to establish SSH connection to 22.214.171.124 - Cause: Authentication failed on device 3 times. TELNET: Failed to establish TELNET connection to 126.96.36.199 - Cause: Connection refused. PRIMARY-STARTUP config Fetch Operation failed for TFTP.
Which seems to mean that SSH does not work, which is false as I manually connects to the device from the LMS host successfully. Network devices access is authenticated against ACS servers using TACACS+ so there should be no problem with credential discrepency here.
Any suggestions for how I could further troubleshoot this? Thanks in advance!
[EDIT] -- The devices that LMS did succeed in archiving their configs are all ACE modules -- not sure if that makes a difference.
It turns out that the failed "SNMPv2c Write" was the cause of the problem. Somehow, the SNMP R/W string that I believe that I have configured in my default credential set was not applied to the discovered devices.
Re-enter the SNMP write string into all devices in the DCR fixed it.
I didn't suspect the SNMP write failure because when I did a credentials checking succeeded on the failed devices, which turned out not to be real "successes". LMS simply did nothing when there is no credential configured and declairedit the check a success.
