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

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_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";
      }

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_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);
