for the below function code def bras_command(channel, command, max_wait=5, buffer_size=9999): channel.send(command + '\n') output = b'' total_wait = 0 # Wait up to `max_wait` seconds for data to appear while not channel.recv_ready() and total_wait < max_wait: sleep(1) total_wait += 1 if not channel.recv_ready(): print("⚠️ No output received from BRAS.") return '' # Once output starts arriving, keep reading until delay hits sleep(1) # let full command execute last_chunk_time = time() while True: if channel.recv_ready(): chunk = channel.recv(buffer_size) output += chunk last_chunk_time = time() else: if time() - last_chunk_time > 1.5: # 1.5s of silence = end break sleep(0.2) decoded = output.decode("utf-8", errors="ignore") print(decoded) return decoded i am trying to excute the command command = 'show interfaces descriptions | match 13-3-13-90' but when the function excutes, it gives no output, after many trials i found that this is because when human do it, it should be like typing 'show interfaces desc' and when pressing space it will wait a while then the word desciptions appear, hence '| ' which will wait a second or so, then pressing on 'm' hence space and wait a shorter time than desc hence the word match appear then tryping the string '13-3-13-90' and pressing enter to excute i couldn't simulate it by all means. can anyone help me? here is the output @CMG03-ATO> show interfaces descriptions | match 13-3-13-90 here is what should be expected when excuted @CMG03-ATO> show interfaces descriptions | match 13-3-13-90 ae1114.3182 up up 13-3-13-90-ZHRPC90-ZHRP-ATO-T3182-L1798-P33 ae1114.3186 up up 13-3-13-900-ZHRPC900-ZHRP-ATO-T3186-L1799-P33 Continue reading...
