Connecting to a different vendor

You can choose between supported vendors:

• SSHConnect.CISCO
• SSHConnect.HP
• SSHConnect.HUAWEI

os_type is associated with device prompt (# for Cisco, > for HP/Huawei) and it sends the appropiate commands for disable scrolling after establishing connection.

from devnet_ssh import SSHConnect

session = SSHConnect(host="192.168.213.231",user="huawei",pwd="huawei",os_type=SSHConnect.HUAWEI)

console = session.send_command("display ip routing-table")
for line in console:
    print(line)
