Cisco Prime Infrastructure FTP Backup failure after update to 3.9
I thought I might save someone a bit of grief by explaining an issue I had. Recently we updated Cisco Prime Infrastructure from 3.8 to 3.9, prior to that FTP backups worked flawlessly. I noticed that 3.9 complained about backups not performing, and I thought that was odd as nothing had changed except the update to 3.9.
Prime Infrastructure 3.9 has brought security to DNS traffic by implementing DNS Security Extensions (DNSSEC). This is enabled by default and can be controlled through new Admin CLI option - 'ip dnssec'.
Follow-up to DNSSEC option. We were upgrading our Prime Infrastructure from 3.7 to 3.9 and afterwards could not SYNC our WLC's. On the PI, we dropped into the shell and could not ping or nslookup e.g. our WLC. Solution found while comparing the running-cfgs of 3.7 to 3.9 and realised that "ip dnssec" was defaulted in the config. removing with "no ip dnssec" FIXED the PROBLEM and SYNc on WLC's was then SUCCESSFUL. Maybe this helps you guys as well. Now, I can report back to our open TAC-CASE, that we found the problem. HTH, Scottie
