Python Script for Network Devices

I have a script using Paramiko that logs into network devices and runs some arbitrary command. I need to enhance and upgrade this script. It needs to do the following: - Login to switches (read in from csv or txt file, doesn't matter). - Run a command: "show int status | in connected.*716" The output to that command will look something similar to: switch1#show int status | in connected.*716 Fa2/0/3 connected 716 a-full a-100 10/100BaseTX Fa2/0/38 connected 716 a-full a-100 10/100BaseTX Fa2/0/45 connected 716 a-full a-100 10/100BaseTX Fa3/0/28 connected 716 a-full a-100 10/100BaseTX Fa3/0/37 connected 716 a-full a-100 10/100BaseTX Fa3/0/38 connected 716 a-full a-100 10/100BaseTX switch1# Second Step= I need to take each interface and run the following command: "show mac address-table | in $INTERFACE" Expected output: switch1#show mac address-table | in Gi1/0/22 716 0040.1234.5678 DYNAMIC Gi1/0/22 switch1# Third Step= Also for each interface, I need to run this command: "show interfaces counters errors | in $INTERFACE" Expected Output: switch1#show interfaces counters errors | in Gi1/0/22 Gi1/0/22 0 32 0 33 0 9 Gi1/0/22 0 0 0 0 0 0 0 switch1# (I only need the first line of that output.) Lastly, it all needs to go into a CSV. It should have: switch1, interface, mac address, columns of numbers from the third step. Example: switch1, Gi1/0/22, 0040.1234.5678,0,32,0,33,0,9 Should be a line for each interface on each switch. I will be hitting 50+ switches so multithreading or multiple process at once would be ideal. I have attached the static script I use now as a reference, in no way does it need to be used. I would like a 24 hour turn around if possible. Please ask ANY questions before getting started. I will have to test for you as I cannot allow outside access to my production network.
