If a port that is in STP blocked state is used as an attachment point and the core filter is matched, Wireshark will capture Range support is also the instances can be active. In the list of options for the SSL protocol, you'll see an entry for (Pre)-Master-Secret log filename. To control the packet capture file size, a single file is limited to 200mb and a second file is automatically created once the size is exceeded, both files will then act as a ring buffer where the primary pcap file is used to write active capture data and the *.pcap.1 file is used as a buffer. Not that feature wealthy but, however it's a powerful debugging device especially when developing an app. The packet buffer is stored in DRAM.
