if changing the DNS IP leads to restart, is it only for cisco tomcat or the entire server.

please suggest where to find the path to cisco tomcat service..

Note : i am using 12.x.

Thanks & Regards

Hi,

Please find the path for tomcat.

Cisco Unified Serviceability--> Tools--> Control Center - Network Services

And you can do via CLI

Hi,

I had few times this error "WARNING: DNS unreachable" on the cli after updating DNS.

The best approach for me to update DNS is to start with PUB, SUB then TFTP

replace the {{}} with your IP

delete dns {{CURRENT OLD IP DNS}}
delete dns {{CURRENT OLD IP DNS}}
set network dns primary {{NEW IP DNS}}
utils diagnose test
set network dns secondary {{NEW IP DNS}}
utils diagnose test

for example

delete dns 1.1.1.1
delete dns 2.2.2.2
set network dns primary 3.3.3.3
utils diagnose test
set network dns secondary 4.4.4.4
utils diagnose test
