SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you.
 my $info = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        )
    or die "Can't connect to DestHost.\n";
 my $class      = $info->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

The SNMP::Info::IPv6 class implements functions for mapping IPv6 addresses to MAC addresses, interfaces and more. It will use data from the IP-MIB, IPV6-MIB, or the CISCO-IETF-IP-MIB, whichever is supported by the device.

This class is inherited by Info::Layer3 to provide IPv6 node tracking across device classes.

For debugging purposes you can call this class directly as you would SNMP::Info

 my $info = SNMP::Info::IPv6->new(...);

Inherited Classes

none.

Required MIBs

IP-MIB
IPV6-MIB
CISCO-IETF-IP-MIB

GLOBALS

none.

TABLE METHODS

These are methods that return tables of information in the form of a reference to a hash.

Internet Address Table

$info->ipv6_n2p_addr()
$info->ipv6_n2p_if()
$info->ipv6_n2p_mac()
$info->ipv6_n2p_state()
$info->ipv6_n2p_type()
$info->ipv6_index()

Maps an IPv6 address to an interface "ifIndex"

$info->ipv6_type()

Maps an IPv6 address to its type (unicast, anycast, etc.)

$info->ipv6_pfx_origin()

Maps an IPv6 prefix with its origin (manual, well-known, dhcp, etc.)

$info->ipv6_addr_prefix()

Maps IPv6 addresses with their prefixes

$info->ipv6_addr_prefixlength()

Maps IPv6 addresses with their prefix length

$info->ipv6_addr()

Maps a table instance to an IPv6 address

Internet Address Translation Table

$info->c_inet_phys_address()

Maps an address of type "cInetNetToMediaNetAddressType" on interface "ifIndex" to a physical address.

MUNGES

munge_physaddr()

Takes an octet stream (HEX-STRING) and returns a colon separated ASCII hex string.

parse_inetaddress

Parses an InetAddress as defined by INET-ADDRESS-MIB.

Returns a hashref with the type as defined by InetAddressType, the textual address and optionally the zone_identifier.
