prompt not stripped on some hp procurve switches #1699

Closed sliddjur closed 4 years ago

sliddjur commented 4 years ago

For instance, the show lldp info remote device does not strip the prompt from the command. This causes some headache when using textfsm.

Here is log from lldp = con_procurve.send_command("show lldp info remote-device")

@sliddjur What is the issue? Your output looks correct:


  LocalPort | ChassisId          PortId             PortDescr SysName           
  --------- + ------------------ ------------------ --------- ------------------

Note, you are pretty printing the output (on a string) which makes it harder to read.

sliddjur commented 4 years ago

Yes I missed it on that log. It seems it only happens on some cases. I was able to reproduce it once, but that time I didn't have logging on. I restart my session with logging on, and then the prompt was stripped. Same device, same commands.

ktbyers commented 4 years ago

Okay, yeah would need to capture a log-file for me to help much. You could try increasing global_delay_factor and set it 2 or 4 (in case it is a timing issue). This sounds possible/likely given what you have described.

sliddjur commented 4 years ago

I dont know if this perhaps is related to stripping prompts. But occasionally when running a script on my devices I get error.

This is the error code I got in ipython3.8

I suppose it was from this part of my script. Which sometimes failed, but mostly succeeded. lldp = con_procurve.send_command("show lldp info remote-device", use_textfsm=True)

ktbyers commented 4 years ago

So the issue here is this:

DEBUG:netmiko:[find_prompt()]: prompt is 65432p-swi004-new-office-2etg# 65432p-swi004-new-office-2etg#

It came back with the prompt twice instead of once (on the find_prompt call)

And strangely with no newline/enter between the prompts.

Probably easiest fix is to explicitly terminate the command using expect_string:

lldp = con_procurve.send_command("show lldp info remote-device", expect_string=r"#")

It is going to be hard to fix if HP doesn't put an enter between the prompt. I guess we could also try global_delay_factor=2 (or 4) and slowing down the SSH session.

ktbyers commented 4 years ago

Updated fix here:

https://github.com/ktbyers/netmiko/pull/1827

Most of the work done by @brasswood (as it is based on his original PR)

ktbyers commented 4 years ago

Should be fixed in #1827
