pdu_size
Specifies the maximum payload size (in octets) of the GTPP packet as an integer from 1024 to65400. The
payload includes the CDR and the GTPP header.
payload includes the CDR and the GTPP header.
Caution:
This command is effective only when GTPP single-source is configured, otherwise this command has
no effect.
Usage
The GTPP packet contains headers (layer 2, IP, UDP, and GTPP) followed by the CDR. Each CDR contains
one or more volume containers. If a packet containing one CDR exceeds the configured maximum payload
size, the system creates and send the packet containing the one CDR regardless.
The larger the packet data unit (PDU) size allowed, the more volume containers that can be fit into the CDR.
The system performs standard IP fragmentation for packets that exceed the system’s maximum transmission
unit (MTU).

Important:
The maximum size of an IPv4 PDU (including the IPv4 and subsequent headers) is 65,535. However,
a slightly smaller limit is imposed by this command because the system’s max-pdu-size doesn't include the IPv4 and
