spending too much time to deal with low level expect buffering, exception
catching and pattern matching, especially when you have a mixed vendor
environment, python module "paramiko"/"netmiko" works much better, just
search github.

发帖数: 806 | 11 Good suggestion. But still like pexpect to have the flexibility, esp. with
jump host in between.

这个只support ssh，不支持telnet和console，的确是奇怪

发帖数: 1055 | 14 You have no reason to support telnet in your network, problem with console
is that you may need multiple authentications (first authenticate with
console server, second authentication with device itself), you should only
need console during rare situations, ie device bringup/software upgrade etc.
Production network device management should go through inband or outband
network connections via ssh, snmp, netconf etc.

发帖数: 700 | 15 The world is not perfect. If you need to monitor standby management module,
or a glass room like route servers, or maybe a quick show command or testing
, you need telnet/console.
at least i know, in some tire-1 sp network, they still use telnet to access
routers.
etc.

发帖数: 858 | 21 In modern network telnet is banned because of security concerns. SSH is the
main method to access networking devices remotely.
For Cisco IOS, I am using Python Paramiko(SSH) to access CLI and get the txt
output.
Cisco IOS is not very native with Python and the output is purely txt. It is
very annoying to parse interested values from the output if you want to do
any further analysis.
