SetIPChecksum

SetIPChecksum Element Documentation

NAME

SetIPChecksum — Click element; sets IP packets' checksums

SYNOPSIS

SetIPChecksum()

Batching: Batching natively supported
Ports: 1 input, 1 output
Processing: agnostic

DESCRIPTION

Expects an IP packet as input. Calculates the IP header's checksum and sets the checksum header field.

You will not normally need SetIPChecksum. Most elements that modify an IP header, like DecIPTTL, SetIPDSCP, and IPRewriter, already update the checksum incrementally.

SEE ALSO

CheckIPHeader, DecIPTTL, SetIPDSCP, IPRewriter
