ap_ctl.py

#!/usr/bin/python3
'''

NAME:
ap_ctl.py

PURPOSE:
Script that logs into an AP via Serial, SSH, or Telnet to read data or execute commands

EXAMPLE:

./ap_ctl.py --scheme "serial" "--tty "Serial port for accessing AP" --prompt "#" --dest <ip if using SSH or Telnet> --port <port , none for serial>  --user <user name>
        --passwd <password> --action <command>

In a program: 
ap_info= subprocess.run(["./ap_ctl.py", "--scheme", ap_dict['ap_scheme'], "--prompt", ap_dict['ap_prompt'],"--dest", ap_dict['ap_ip'], "--port", ap_dict["ap_port"],
                                                        "--user", ap_dict['ap_user'], "--passwd", ap_dict['ap_pw'],"--action", "powercfg"],stdout=subprocess.PIPE)
                                
NOTES: 

LANforge 192.168.100.178
Controller at 192.168.100.112 admin/Cisco123
Controller is 192.1.0.10
AP is on serial port /dev/ttyUSB1 or /dev/ttyUSB2  9600 8 n 1 

make sure pexpect is installed:
$ sudo yum install python3-pexpect

You might need to install pexpect-serial using pip:
$ pip3 install pexpect-serial

$ sudo pip3 install pexpect-serial

''' NOTES for AP DFS

#############################

1. Do "show AP summary" on the controller to see the list of AP's connected.
2. Now, check the channel configured on the AP using the commend "show ap  channel <AP-Name>"

3. Check for the current channel and Channel width for Slot id 1. See the output of this command.

4. Before making any changes, please connect at least 1 client to this AP in 5GHz radio. 
Keep running the ping traffic to the default gateway of the AP.

4. Now, configure dfs channel for this AP with 20MHz as channel width.

6. After CAC Expiry, Client should connect back - Verify the pings are passing through or not.
Note time:  
"show logging" in the AP will show the CAC timer details. You can grep for "DFS CAC timer enabled time 60" and "changed to DFS channel 52, running CAC for 60 seconds.
Wait for 60 sec and check for this log "CAC_EXPIRY_EVT: CAC finished on DFS channel 52"

[*07/07/2020 23:37:48.1460] changed to DFS channel 52, running CAC for 60 seconds.
[*07/07/2020 23:38:48.7240] CAC_EXPIRY_EVT: CAC finished on DFS channel 52

"make a note of the time and check the CAC timer expired in 60-61 seconds.

7. Now, trigger the radar on Channel 52. AP should move to another channel.
 Also, When the radar is triggered, capture the CSA frames and verify the CSA count is set to 10 or not.

 8. Now, verify the black-list time of the channel for this AP.  : show ap auto-rf 802.11a <AP-Name>
 In the controller, give the command "show ap auto-rf 802.11a <AP-Name>" under Radar information you should see the "Detected Channels and Blacklist Times" . 
Black list time will be 1800 seconds which is 30 minutes.
