Paramiko Timeout issue

[WindfuryARS]

I got a problem regarding "paramiko.buffered_pipe.PipeTimeout". My script could have expected output while I'm executing it on my MAC

from netmiko import ConnectHandler
from datetime import datetime
import time
import getpass


def getPTPstate(username,pw):
    cisco = {
        'device_type': 'cisco_nxos',
        'host': "10.122.164.139",
        'username': username,
        'password': pw
    }
    all_device = [cisco]
    
    for i in all_device:
        net_connect = ConnectHandler(**i)
        output1 = net_connect.send_command("show ptp clock | in Identity | awk  '{print $4}'").strip("\n")
        output2 = net_connect.send_command('show switchname').replace(" ","").strip()
        print(output2 + "'s PTP GM is " + output1)


getPTPstate("admin","cisco!123")

$ python3 /Users/hancai/Desktop/ptplogin.py
F340.09.16-93180YC-FX-CD1_N93-1's PTP GM is 00:de:fb:ff:fe:fa:47:87

Somehow, it would return incorrect output if I was running same script in another server. I suppose there is performance issue in server, do we have any way to extend Timeout value?

$ python3 ptplogin.py

What's netmiko ? this code is only tested with paramiko...
