Can you post the code for the device you are connecting to? Are you sure you properly passed in a hostname/IP address? The above error doesn't show the hostname or IP address (which makes me think that it is missing). |

Hi,
I am new to python network automation and I am trying to use NAPALM to connect to Cisco switches , I can connect to switches with IOS 15 , but when i try to connect to switch with IOS 12.2(25)SEE3 i get this error :
Traceback (most recent call last):
File "C:\Users\automation\AppData\Roaming\Python\Python39\site-packages\netmiko\base_connection.py", line 1046, in establish_connection
self.remote_conn_pre.connect(**ssh_connect_params)

raise NetmikoTimeoutException(msg)
netmiko.exceptions.NetmikoTimeoutException: TCP connection to device failed.
Common causes of this problem are:
Device settings: cisco_ios
During handling of the above exception, another exception occurred:

raise ConnectionException("Cannot connect to {}".format(self.hostname))
napalm.base.exceptions.ConnectionException: Cannot connect to
is it related to the CISCO IOS and is there anyway to mitigate this issue
