# Using non-standard SSH port for IOS router
Verify Ansible playbook using non-standard SSH port to an IOS router.
## Configure the router

```
csr1000v-1#config t

ip ssh port 2222 rotary 1

line vty 0 4
 login local
 rotary 1

exit
```

## Enable debug

Verify the control host is using port 2222

```
csr1000v-1#debug ip tcp transactions port 2222
```

## Configure Ansible inventory
Create a group or host with the following configuration:

```
    sshport2222:
      hosts:
        csr1000v-1.sandbox.wwtatc.local: {}
      vars:
        ansible_connection: network_cli
        ansible_network_os: ios
        ansible_become: yes
        ansible_become_method: enable
        ansible_ssh_user: admin
        ansible_port: 2222
```
