Cisco CML and Cisco VIRL-PE Cisco CML and Cisco VIRL-PE software releases 2.0 and later do not run the salt-master service. For Cisco CML and Cisco VIRL-PE deployed in standalone mode, administrators can check the status of the salt-master service and disable the service as shown in the following example: virl@virl:~$ sudo systemctl status salt-master ? salt-master.service - The Salt Master Server Loaded: loaded (/lib/systemd/system/salt-master.service; disabled; vendor preset: enabled) Drop-In: /etc/systemd/system/salt-master.service.d +-override.conf Active: active (running) since Thu 2020-05-28 17:55:10 GMT; 1s ago Docs: man:salt-master(1) file:///usr/share/doc/salt/html/contents.html https://docs.saltstack.com/en/latest/contents.html --- Output Omitted --- virl@virl:~$ sudo systemctl stop salt-master virl@virl:~$ sudo systemctl disable salt-master Synchronizing state of salt-master.service with SysV init with /lib/systemd/systemd-sysv-install...
