Most of the time, a packet capture (PCAP) file is the first thing we look to while troubleshooting an issue, because we find that solves the problem in most cases. Corrective action is what is required next, which shouldn’t be much of an issue.
A PCAP is a file that contains the network’s voice and data traffic as it happens in your environment with real-time network activity and traffic. This makes the PCAP helpful in most troubleshooting cases as it closely simulates the real-time traffic in your network.
You could use Wireshark to get a packet capture.
Or, if you’d prefer to keep it simple, you need do no more than just type a line of command. Our built-in sniffer tool does this job well. Navigate to your <VQManager_Home>/bin directory and execute this one-liner.
sniffer.exe -i=<Exact interface where VQManager listens> -cap.file=test.pcap -filter=”tcp || udp || vlan” -p=true -packet.count=10000
In case, you are running VQManager on a Linux machine, try this.
./sniffer -i=<Exact interface where VQManager listens> -cap.file=test.pcap -filter=”tcp || udp || vlan” -p=true -packet.count=10000
You will have the test.pcap file ready in an instant. This will be present in the current directory(bin). Send it to us for analysis and we will get back to you promptly with the required corrective measure.
Should you face a more serious problem, we may ask you for more information. Well, that’s for another post.
