Hi all.
I've a little problem with my PI 3.3
Some devices are properly displayed with the dns-name. Some not ...
The DNS-entries are correct. The ip domain-name is also defined.
Here is the Show running from the CLI
hostname PRIME01
!
ip domain-name XXXXXXX.YZ
!
interface GigabitEthernet 0
ip address 10.0.0.12 255.255.255.0
ipv6 address autoconfig
!
ip name-server 10.0.0.30 10.0.0.116 10.16.0.4
!
ip default-gateway 10.0.0.1
!
clock timezone CET
!
ntp server 10.250.0.45
!
username admin password hash. role admin
!
service sshd
!
repository NTM
url ftp://10.0.0.49/
user admin password hash
repository defaultRepo
url disk:/defaultRepo
!
password-policy
lower-case-required
upper-case-required
digit-required
no-username
disable-cisco-passwords
min-password-length 6
!
logging localhost
logging loglevel 6
!
cdp timer 60
cdp holdtime 180
cdp run GigabitEthernet 0
!
icmp echo on
!
The DNS-Servers are accessible (ping, traceroute)
All ideas what the problem could be, are welcome :)
Regards
Markus

Prime infrastructure uses DNS to resolve names to IP addresses, but also does reverse lookup's where it tries to resolve and IP address to a name.
Check for the devices where you see issues, if it works both ways and adjust your DNS if it doesn't.
You can open a root shell and test with dig or nslookup

The DNS-Servers are working as DNS and also as Reverse-DNS.
I've tested this from the PI-Server and from several devices as well. It works.
Some other ideas?

Well, guys .... I've solved the problem by deleting the devices and a new add (manually) of them.
I don't know why .... but it works ...
Never the less, the main problem is not solved completely.
Viewing to the performance data dashboard (e.g. Top-N Server), the end-hosts are displayed by IP-Address.
I've enabled:
Administration > Settings > System Settings > Client and User > Client > Lookup client host names from DNS server
Should I do additional things to display the names?
