The "pcap trace ..." debug cli shown below is not current. Which vpp release / branch are you using?

I can see two options. But one of them is not working for multi-core. And another is not allowing me to capture packets based on a tcpdump filter. Option # 1 vpp# pcap tx trace on intfc GigabitEthernet0/11/0 file gige_tx.pcap I am not able to make that work for multi-core use-case. Also, it captures rx and tx using different commands. Optiojn # 2 The other option that I found is creating a span to mirror packets. vpp# create packet-generator interface p vpp# packet-generator capture pg0 pcap /tmp/mycap.pcap vpp# set interface span GigabitEthernet0/11/0 destination pg0 vppctl> set interface state pg0 up However, I am not able use tcpdump filters in this case. Any ideas?
