# Packet capture configuration
#
# Packet capture is supported at the MAC, MAC_NR, and NAS layer. 
# MAC-layer packets are captured to file a the compact format decoded 
# by the 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
# NAS-layer packets are dissected with DLT=148, and Protocol = nas-eps.
