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.

IS srsenb run on IPv6?

Issue Description

Setup Details

srsENB configuration file

eNB configuration

enb_id: 20-bit eNB identifier.

note: When enabling MBMS, use the sib.conf.mbsfn configuration file which includes SIB13

rr_config: Radio Resources configuration file

rb_config: SRB/DRB configuration file

RF configuration

dl_earfcn: EARFCN code for DL (only valid if a single cell is configured in rr.conf)

tx_gain: Transmit gain (dB).

rx_gain: Optional receive gain (dB). If disabled, AGC if enabled

Optional parameters:

dl_freq: Override DL frequency corresponding to dl_earfcn

ul_freq: Override UL frequency corresponding to dl_earfcn (must be set if dl_freq is set)

device_name: Device driver family

Supported options: "auto" (uses first driver found), "UHD", "bladeRF", "soapy", "zmq" or "Sidekiq"

device_args: Arguments for the device driver. Options are "auto" or any string.

Default for UHD: "recv_frame_size=9232,send_frame_size=9232"

Default for bladeRF: ""

time_adv_nsamples: Transmission time advance (in number of samples) to compensate for RF delay

from antenna to timestamp insertion.

Default "auto". B210 USRP: 100 samples, bladeRF: 27

For best performance in 2x2 MIMO and >= 15 MHz use the following device_args settings:

USRP B210: num_recv_frames=64,num_send_frames=64

And for 75 PRBs, also append ",master_clock_rate=15.36e6" to the device args

For best performance when BW<5 MHz (25 PRB), use the following device_args settings:

USRP B210: send_frame_size=512,recv_frame_size=512

Example for ZMQ-based operation with TCP transport for I/Q samples

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.

enable: Enable MAC layer packet captures (true/false)

filename: File path to use for LTE MAC packet captures

nr_filename: File path to use for NR MAC packet captures

s1ap_enable: Enable or disable the PCAP.

s1ap_filename: File name where to save the PCAP.

mac_net_enable: Enable MAC layer packet captures sent over the network (true/false default: false)

bind_ip: Bind IP address for MAC network trace (default: "0.0.0.0")

bind_port: Bind port for MAC network trace (default: 5687)

client_ip: Client IP address for MAC network trace (default: "127.0.0.1")

client_port Client IP address for MAC network trace (default: 5847)

Log configuration

Log levels can be set for individual layers. "all_level" sets log

level for all layers unless otherwise configured.

Format: e.g. phy_level = info

In the same way, packet hex dumps can be limited for each level.

"all_hex_limit" sets the hex limit for all layers unless otherwise

configured.

Format: e.g. phy_hex_limit = 32

Logging layers: rf, phy, phy_lib, mac, rlc, pdcp, rrc, gtpu, s1ap, stack, all
