NAME
Net::CDP::Address - Cisco Discovery Protocol (CDP) port address
SYNOPSIS
use Net::CDP::Address qw(:protos);
# Constructors
$address = new Net::CDP::Address($ip);
$address = new Net::CDP::Address($protocol, $packed);
$cloned = clone $address;
# Object methods
$protocol = $address->protocol;
$address = $address->address;
$packed = $address->packed;
DESCRIPTION
A Net::CDP::Address object represents a single addres in the Addresses field of a CDP packet. Net::CDP::Address objects are immutable.
CONSTRUCTORS
- new
-
$address = new Net::CDP::Address($ip) $address = new Net::CDP::Address($protocol, $packed)
Returns a new Net::CDP::Address object.
If only one argument is provided,
new
will attempt to parse it as an IPv4 or IPv6 address.Otherwise, you must specify the protocol and the bytes that comprise the address.
$protocol
should be one of the following constants:CDP_ADDR_PROTO_CLNP CDP_ADDR_PROTO_IPV4 CDP_ADDR_PROTO_IPV6 CDP_ADDR_PROTO_DECNET CDP_ADDR_PROTO_APPLETALK CDP_ADDR_PROTO_IPX CDP_ADDR_PROTO_VINES CDP_ADDR_PROTO_XNS CDP_ADDR_PROTO_APOLLO
These constants can be exported using the tag
:protos
. See Exporter.$packed
must be a string consisting of the bytes that make up the address in network order. You may find thepack
function useful in generating this string. - clone
-
$cloned = clone $packet
Returns a deep copy of the supplied Net::CDP::Address object.
OBJECT METHODS
- protocol
-
$protocol = $address->protocol()
Returns this address's protocol.
- address
-
$ip = $address->address()
If this is an IPv4 or IPv6 address, returns its standard string representation, otherwise
undef
. - packed
-
$packed = $address->packed()
Returns this address as a string consisting of the bytes that comprise it in network order.
