Hello, I have a playbook and inventory list. I will run a task for only one host from inventory list. Is there any way to do this? - hosts: eos\_switches connection: local tasks: - name: Gather Show Version Facts eos\_command: commands: - ‘show version’ register: showvers - debug: var: showvers - name: Create vlan eos\_vlan: vlan\_id: 4091 name: CONNECTION-P2P state: present - name: configure interface eos\_interface: name: ethernet1 description: CONNECTION-P2P speed: 100full mtu: 1500 - name: Ensure Ethernet1 is a trunk port eos\_l2\_interface: name: Ethernet1 mode: trunk native\_vlan: 1 trunk\_allowed\_vlans: 4091 - name: Set ethernet1 IPv4 address eos\_l3\_interface: provider: host: eos\_switches[‘192.168.81.139’] transport: eapi use\_ssl: yes validate\_certs: no username: eapi password: icantellyou name: vlan4091 ipv4: 192.168.0.1/30 - name: Set ethernet1 IPv4 address\_2 eos\_l3\_interface: provider: host: eos\_switches[‘192.168.81.140’] transport: eapi use\_ssl: yes validate\_certs: no username: eapi password: icantellyou name: vlan4091 ipv4: 192.168.0.2/30 ---

I guess eos\_switches is a group? Instead of using the group, just use the name of the switch - hosts: my\_lonely\_switch ---

Hi Kai, Some tasks will play for all hosts that are in in my host file. But some tasks will play per host. For example, I am using IP assignment to hosts. HOST A will take 192.168.0.1/24 and host B 192.168.0.2/24. So tasks should be run seperately for those hosts. Should I create another playbook for per host? Or is there any way to send spesific task for spesific host in one playbook?

If everything is the same but only some parameters is different I would use the same playbook, and put the differences in variables. Ansible has the possibility to have variables many places[1], inventory, host\_vars, group\_vars, play and so on. So instead of hard coding the variables in the play/playbook use variable instead, and have different values in the variables for different switches.
