At the moment we are updating our Datacenter Fabric Environment. Coming from DCNM 11.5.1 we've installed Nexus Dashboard 2.1.2d and NDFC 12.0.2f. After installation we've Installed the Backup from the Original DCNM successfull.
Nexus Switch Software Version is 9.3.3
The complete Management via the NDFC was fine there
As the next Step we've updated the ND & NDFC to 2.3.2d & 12.1.2e and now we see ssh Problems .
The Fabric doesn't become "green" and we are seeing critical Alarms with "Switch SSH Unreachable". And that toggeling, sometimes a Switch becomes "green" somtimes the Alarm happened. When you look into the Switch Logs the Log says:
pam_aaa:Authentication failed from a.b.c.d
fatal: PAM: pam_setcred(): Authentication failure - dcos_sshd[1395]
LAN Credentials Management seems to be ok, all Validations there are ok.
Are there changed Setting that we have to consider.
Solved! Go to Solution.

We've solved that problem. it was our Freeradius that has a limited amount of LDAP Sesions behind. The NDFC seems to do all logins parallel.
