Routing

Hi In order to send a batch of commands correctly to router, we could use script to send command line by line in Putty. Anyone can give some suggestions how to do that? The below is link for CRT. Do you think Putty has similar way to do that? Thank you

Hi eesunj,

I don't know anything regarding this for Putty, but an alternative solution could be using "load set terminal" instead of just pasting commands in configuration mode. That way commands are only evaluated after finished the load via the ctrl+D. Example with only two commands but it can easily be 100 of set commands.

jh@fw# load set terminal
[Type ^D at a new line to end input]
delete security
delete interfaces
<hit ctrl+d>
load complete

[edit]
jh@fw#

This way you avoid issues with flow control 🙂

Hope this helps.

Great! Thank you

it improve a lot that way, but occassionally it does not work well. It means it still send some error commands. 

Try adding  crt.sleep <>

I used to add 1000's of lines without any issues.

"Try adding  crt.sleep <> .."

Can you explain it in detail? Thanks 

I was trying to say; please add sleep in the script used to push the config. Example,

crt.sleep 3000000 <---- VBScript.
sleep NUMBER[SUFFIX] <---- Bash Script Sleep

Moreover this is a flow control issue. To overcome this if the config changes are much big; please change the script to ftp the config changes to the box and later merge it with

user@host# load merge filename relative

SAMPLE SCRIPT

#$language = "VBScript"
#$interface = "1.0"

Sub main

Dim i
i = 1000000


Do While i > 10

crt.Screen.WaitForString ">"
crt.Screen.Send "show arp no-resolve expiration-time " & chr(124) & " match " & chr(34) & " 10.67.5.33 " & chr(124) & " 10.67.5.34 " & chr(124) & " 10.74.13.144 " & chr(124) & " 10.74.13.145 " & chr(124) & " 10.74.13.147 " & chr(124) & " 10.84.6.34 " & chr(124) & " 10.84.37.20 " & chr(124) & " 10.84.128.20 " & chr(124) & " 10.84.136.36 " & chr(124) & " 10.166.36.4 " & chr(124) & " 10.166.36.12 " & chr(124) & " 10.166.36.20 " & chr(124) & " 10.166.36.28 " & chr(124) & " 10.166.36.36 " & chr(124) & " 10.166.36.44 " & chr(124) & " 10.166.36.52 " & chr(124) & " 10.166.36.60 " & chr(124) & " 10.166.36.68 " & chr(124) & " 10.166.36.76 " & chr(124) & " 10.166.36.84 " & chr(124) & " 10.166.36.92 " & chr(34) & " " & chr(124) & " no-more " & chr(13)

crt.sleep 3000000

i = i - 1

Loop

crt.Screen.WaitForString "#"
crt.Screen.Send "commit" & VbCr

MsgBox "Done" & VbCr

End Sub
