FAQPage Schema

How do I capture network traffic on a Cisco Modeling Labs link?▼

To capture network traffic on a Cisco Modeling Labs (CML) link, you can start a packet capture directly on a specified link within your running lab, apply filters, and then download the pcap file for offline analysis.

Can I download pcap files from CML for Wireshark analysis?▼

Yes, you can download pcap files from CML. After stopping a packet capture on a lab link, retrieve the captured data for offline inspection and use it with analysis tools like Wireshark or tshark.

What is the best way to troubleshoot BGP peering issues in a CML environment?▼

The best way to troubleshoot BGP peering issues in CML is to start a packet capture on the relevant link, download the pcap file, and analyze the BGP messages for errors or misconfigurations using integrated packet analysis tools.

Does CML packet capture support filtering specific protocols like OSPF and ICMP?▼

Yes, CML packet capture supports filters for specific protocols. You can apply packet counts and protocol filters during capture to isolate traffic like OSPF and ICMP for detailed performance analysis and troubleshooting.

How do I start and stop packet captures on CML lab links?▼

You can start and stop packet captures on CML lab links by specifying the target link in your running lab. Initiate the capture to begin recording traffic, then stop it to finalize and download the pcap file.
