Python For Network Engineers 2

(1) Create switch VLANs using loops

Ubuntu-1

• Create VLAN using loop function (Figure 1)
  • Use “for” to create loop
  • Notice that there is an error when we try to run the script, can’t mix “str” and “int” objects
• Fix the error (Figure 2)
  • Change integer to string using str(n)
• Connect to multiple switches (Figure 3)
  • Use “for” to create loop

(2) Opening Files and spacing importance

Ubuntu-1

• Read the list of Switch IP addresses from a file
  • Create new text file: myswitches (Figure 1)
  • Use “open()” function to open file (Figure 2)
• White spacing makes different logic
  • Using the same level of spacing groups the line of codes together under the loop function (Figure 3)
  • We don’t want the “end”, “wr”, and “exit” to be inside the loop (Figure 4)
• Script link
