nullpdu
Syntax
nullpdu {
protocol (ID-0x0000 | ID-0xFFFF);
}
Hierarchy Level
[edit security sctp]
Description
Use the nullpdu function to configure the Stream Control Transmission Protocol (SCTP) null protocol data unit (PDU) value. If you set the null PDU value to 0xFFFF, then the payload protocol identifier value is replaced with 0xFFFF and the user data field is not modified. If you set the null PDU value to 0x0000, then the payload protocol identifier value is replaced with 0x0000 and the first four bytes of the user data field is replaced with zeroes. If all chunks in a packet are null PDUs, the SCTP firewall drops the packet.
From Junos OS Release 20.4R1 onwards, the [edit security gprs sctp]
hierarchy level is replaced by [edit security sctp].
