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 "Cant connect to DestHost.\n";

 my $class = $vtp->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";



DESCRIPTION

SNMP::Info::CiscoVTP is a subclass of SNMP::Info that provides information about a Cisco 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

GLOBALS

$vtp->vtp_version() (vtpVersion)
$vtp->vtp_maxstore() (vtpMaxVlanStorage)
$vtp->vtp_notify() (vtpNotificationsEnabled)
$vtp->vtp_notify_create() (vtpVlanCreatedNotifEnabled)
$vtp->vtp_notify_delete() (vtpVlanDeletedNotifEnabled)
$vtp->vtp_trunk_set_serial() (vlanTrunkPortSetSerialNo)

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, $if_map{FastEthernet0/1})
    or die "Couldnt change port VLAN. ",$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, $if_map{FastEthernet0/1})
    or die "Couldnt change port default VLAN. ",$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, $if_map{FastEthernet0/1})
    or die "Couldnt add port to egress list. ",$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, $if_map{FastEthernet0/1})
    or die "Couldnt add port to egress list. ",$vtp->error(1);
