## Examples:

Create a dictionary representing the device.

Supported device_types can be found here, see CLASS_MAPPER keys.

from netmiko import ConnectHandler

cisco_881 = {
    'device_type': 'cisco_ios',
    'ip':   '10.10.10.10',
    'username': 'test',
    'password': 'password',
    'port' : 8022,          # optional, defaults to 22
    'secret': 'secret',     # optional, defaults to ''
    'verbose': False,       # optional, defaults to False
}

#### Establish an SSH connection to the device by passing in the device dictionary. ```py net_connect = ConnectHandler(**cisco_881) ```
#### Execute show commands. ```py output = net_connect.send_command('show ip int brief') print(output) ``` ``` Interface IP-Address OK? Method Status Protocol FastEthernet0 unassigned YES unset down down FastEthernet1 unassigned YES unset down down FastEthernet2 unassigned YES unset down down FastEthernet3 unassigned YES unset down down FastEthernet4 10.10.10.10 YES manual up up Vlan1 unassigned YES unset down down ```
#### For long-running commands, use `send_command_expect()`

send_command_expect waits for the trailing prompt (or for an optional pattern)

net_connect.send_command_expect('write memory')

Building configuration...
[OK]

#### Enter and exit enable mode. ```py net_connect.enable() net_connect.exit_enable_mode() ```
#### Execute configuration change commands (will automatically enter into config mode) ```py config_commands = [ 'logging buffered 20000', 'logging buffered 20010', 'no logging console' ] output = net_connect.send_config_set(config_commands) print(output) ``` ``` pynet-rtr1#config term Enter configuration commands, one per line. End with CNTL/Z. pynet-rtr1(config)#logging buffered 20000 pynet-rtr1(config)#logging buffered 20010 pynet-rtr1(config)#no logging console pynet-rtr1(config)#end pynet-rtr1# ```
