DESCRIPTION

class Net::Packet::ICMP

is Net::Packet::Base

Attributes

.decode($frame, Net::Packet::Base $parent?) returns Net::Packet::ICMP

    $icmp.id = ...
    my $id = $eth.id.

.sequence_number() returns Proxy is rw
  Returns a Proxy for the sequence number of this packet. Only valid for specific
  combinations of $.type and $.code, as per ICMP specification, else it dies.
  Usage:
    $icmp.sequence_number = ...
    my $id = $eth.sequence_number.
