UDP Checksum is shown zero in Subscriber Data Packets #224

Closed DharmendraShetty closed 6 months ago

DharmendraShetty commented 7 months ago

Description:

UDP Checksum is shown zero in Subscriber Data Packets

Upstream datapackets of PPPoE subscribers captured, and if we observe the pcap file, in udp header, the udp checksum is shown as zero.

Feature Ask:

We need a support of IPv4 & UDP checksum calculation as well as verification

Snapshot of PCAP attached:

UDP_Checksum_Zero_InDataPkts

Thanks, Dharmendra
