# Packet capture configuration
#
# MAC-layer packets are captured to a file in the compact format which can
# be decoded by Wireshark. For decoding, use the UDP dissector and the UDP
# heuristic dissection. Edit the preferences (Edit > Preferences >
# Protocols > DLT_USER) for DLT_USER to add an entry for DLT=149 with
# Protocol=udp. Further, enable the heuristic dissection in UDP under:
# Analyze > Enabled Protocols > MAC-LTE > mac_lte_udp and MAC-NR > mac_nr_udp
# For more information see: https://wiki.wireshark.org/MAC-LTE
# Configuring this Wireshark preferences is needed for decoding the MAC PCAP
# files as well as for the live network capture option.
#
# Please note that this setting will by default only capture MAC
# frames on dedicated channels, and not SIB. You have to build with
# WRITE_SIB_PCAP enabled in srsenb/src/stack/mac/mac.cc if you want
# SIB to be part of the MAC pcap file.
#
# S1AP Packets are captured to a file in the compact format which can
# be decoded by the Wireshark s1ap dissector with DLT 150.
# To use the dissector, edit the preferences for DLT_USER to
# add an entry with DLT=150, Payload Protocol=s1ap.
