FMC local and static Hostname to IP mapping table.

servio.lara — Mon, 06 Sep 2021 20:49:22 GMT

Is there any place in the FMC to set an IP to hostname static mapping for DNS resolution?

Best regards.

Yes, login to FMC CLI and go to expert mode. Then after sudo su, edit the
hosts file (vi /etc/hosts).

If you know VI editor in linux then start adding hosts entries. This is
pure linux configuration and not specific to FMC.

@servio.lara ,

If you mean the FMC itself add static dns entry for local use then access FMC in expert mode with sudo su privilege and type : echo " ip domain" >> /etc/hosts

Example :
echo "192.168.40.2 lab.ccie-security.com" >> /etc/hosts

root@FMC178:/Volume/home/admin# ping lab.ccie-security.com
PING lab.ccie-security.com (192.168.40.2) 56(84) bytes of data.
64 bytes from lab.ccie-security.com (192.168.40.2): icmp_req=1 ttl=128 time=0.245 ms
64 bytes from lab.ccie-security.com (192.168.40.2): icmp_req=2 ttl=128 time=0.305 ms
64 bytes from lab.ccie-security.com (192.168.40.2): icmp_req=3 ttl=128 time=0.383 ms

64 bytes from lab.ccie-security.com (192.168.40.2): icmp_req=5 ttl=128 time=0.386 ms

If it is not the query you asked for, please let me know!

Hope that helps!

in FMC under system/configuration/ management interfaces ( network ) you
may assign the fqdn of the fmc then in the related DNS zone create its A
record to map the FMC’s name to the resolved IP.
