NAME
Net::SNMP::Mixin::Dot1qFdb - mixin class for 802.1-Q switch forwarding
databases

VERSION
Version 0.04

SYNOPSIS
use Net::SNMP;
use Net::SNMP::Mixin qw/mixer init_mixins/;

my $session = Net::SNMP->session( -hostname => 'foo.bar.com' );
$session->mixer('Net::SNMP::Mixin::Dot1qFdb');
$session->init_mixins();
snmp_dispatcher() if $session->nonblocking;
die $session->error if $session->error;

foreach my $fdb_entry ( $session->get_dot1q_fdb_entries() ) {
my $mac = $fdb_entry->{MacAddress};
my $fdb_id = $fdb_entry->{fdbId};
my $vlan_id = $fdb_entry->{vlanId};
my $port = $fdb_entry->{dot1dBasePort};
my $status = $fdb_entry->{fdbStatus};

print "$mac, $fdb_id, $vlan_id, $port, $status\n";
}

DESCRIPTION
A Net::SNMP mixin class for forwarding database info of 802.1-Q
compatible switches. The switches must support parts of the standard
Q-BRIDGE-MIB.

Sorry to disappoint you, Cisco isn't standard conform, but you knew this
already, for sure!

MIXIN METHODS
@fdb = OBJ->get_dot1q_fdb_entries()
Returns a list of fdb entries. Every list element is a reference to a
hash with the following fields and values:

{
MacAddress => 'XX:XX:XX:XX:XX:XX',
dot1dBasePort => Integer,
fdbId => Integer,
vlanId => Integer,
fdbStatus => Integer,
fdbStatusString => String,
}

MacAddress
MacAddress received, in normalized IEEE form XX:XX:XX:XX:XX:XX.

dot1dBasePort
The receiving bride-port for the MAC address.

fdbId
MacAddress is member of the FDB with this fdbId. dot1q bridges
support many forwarding databases.

vlanId
Every fdbId is related to a distinct vlanId.

fdbStatus
The status of this entry. The meanings of the values are:

1 = other
2 = invalid
3 = learned
4 = self
5 = mgmt

For more information please see the corresponding Q-BRIDGE-MIB.

fdbStatusString
The status of this entry in string form, see above.

INITIALIZATION
OBJ->_init($reload)
Fetch the fdb related snmp values from the host. Don't call this method
direct!

PRIVATE METHODS
Only for developers or maintainers.

_fetch_dot1q_fdbid()
Fetch some columns from the VlanCurrentTable once during object
initialization. MAC addresses in the forwarding database are related to
fbd ids and the fbd ids are related to vlan ids by this column.

_fetch_dot1q_tp_fdb_table()
Fetch the forwarding databases from the dot1qTpFdbTable once during
object initialization.

SEE ALSO
Net::SNMP::Mixin::Dot1dBase for a mapping between ifIndexes and
dot1dBasePorts.

REQUIREMENTS
Net::SNMP, Net::SNMP::Mixin
