SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $vtp = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";

device's VLAN and VTP Domain membership.
Use or create in a subclass of SNMP::Info. Do not use directly.
Inherited Classes
None.
Required MIBs
CISCO-VTP-MIB
CISCO-VLAN-MEMBERSHIP-MIB
CISCO-VLAN-IFTABLE-RELATIONSHIP-MIB
MIBs can be found at ftp://ftp.cisco.com/pub/mibs/v2/v2.tar.gz

TABLE METHODS
Your device will only implement a subset of these methods.
$vtp->i_vlan()
Returns a mapping between "ifIndex" and assigned VLAN ID for access ports and the
default VLAN ID for trunk ports.
$vtp->i_untagged()
An alias for "i_vlan".
$vtp->i_vlan_membership()
Returns reference to hash of arrays: key = "ifIndex", value = array of VLAN IDs.
These are the VLANs which are members of enabled VLAN list for the port.
Example:
my $interfaces = $vtp->interfaces();
my $vlans = $vtp->i_vlan_membership();
foreach my $iid (sort keys %$interfaces) {
my $port = $interfaces->{$iid};
my $vlan = join(',', sort(@{$vlans->{$iid}}));
print "Port: $port VLAN: $vlan\n";
}
$vtp->i_vlan_membership_untagged()
Returns reference to hash of arrays: key = "ifIndex", value = array of VLAN IDs.
These are the VLANs which are members of the untagged egress list for the port.

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