=head1 NAME
SNMP::Info::CiscoVTP - SNMP Interface to Cisco's VLAN Management MIBs
=head1 AUTHOR
Max Baker
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $vtp = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly on to SNMP::Session
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $vtp->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
SNMP::Info::CiscoVTP is a subclass of SNMP::Info that provides
information about a Cisco device's VLAN and VTP Domain memebership.
Use or create in a subclass of SNMP::Info. Do not use directly.
=head2 Inherited Classes
None.

=head1 TABLE METHODS
Your device will only implement a subset of these methods.

=item $vtp->i_vlan()
Returns a mapping between ifIndex and assigned VLAN ID for access ports and the
default VLAN ID for trunk ports.

These are the VLANs which are members of enabled VLAN list for the port.

=head1 SET METHODS
These are methods that provide SNMP set functionality for overridden methods or
provide a simpler interface to complex set operations. See
L<SNMP::Info/"SETTING DATA VIA SNMP"> for general information on set operations.
=over
=item $vtp->set_i_vlan ( vlan, ifIndex )
Changes an access (untagged) port VLAN, must be supplied with the numeric
VLAN ID and port ifIndex. This method should only be used on end station
(non-trunk) ports.
Example:
my %if_map = reverse %{$vtp->interfaces()};
$vtp->set_i_vlan('2', $if_map{'FastEthernet0/1'})
or die "Couldn't change port VLAN. ",$vtp->error(1);
=item $vtp->set_i_pvid ( pvid, ifIndex )
Sets port default VLAN, must be supplied with the numeric VLAN ID and
port ifIndex. This method should only be used on trunk ports.
Example:
my %if_map = reverse %{$vtp->interfaces()};
$vtp->set_i_pvid('2', $if_map{'FastEthernet0/1'})
or die "Couldn't change port default VLAN. ",$vtp->error(1);
=item $vtp->set_add_i_vlan_tagged ( vlan, ifIndex )
Adds the VLAN to the enabled VLANs list of the port, must be supplied with the
numeric VLAN ID and port ifIndex.
Example:
my %if_map = reverse %{$vtp->interfaces()};
$vtp->set_add_i_vlan_tagged('2', $if_map{'FastEthernet0/1'})
or die "Couldn't add port to egress list. ",$vtp->error(1);
=item $vtp->set_remove_i_vlan_tagged ( vlan, ifIndex )
Removes the VLAN from the enabled VLANs list of the port, must be supplied
with the numeric VLAN ID and port ifIndex.
Example:
my %if_map = reverse %{$vtp->interfaces()};
$vtp->set_remove_i_vlan_tagged('2', $if_map{'FastEthernet0/1'})
or die "Couldn't add port to egress list. ",$vtp->error(1);
