DEPRECATED

Use the new modul Net::SNMP::Mixin::CiscoDot1qVlanStatic instead, it supports trunk- AND access-ports

NAME

Net::SNMP::Mixin::CiscoDot1qVlanStaticTrunks - mixin class for static Cisco IEEE-trunks info

VERSION

Version 0.04

SYNOPSIS

  use Net::SNMP;
  use Net::SNMP::Mixin;

  # initialize session and mixin library
  my $session = Net::SNMP->session( -hostname => 'foo.bar.com' );
  $session->mixer('Net::SNMP::Mixin::CiscoDot1qVlanStaticTrunks');
  $session->init_mixins;
  snmp_dispatcher();
  $session->init_ok();
  die $session->errors if $session->errors;

  # show VLAN IDs and corresponding names
  my $id2name = $session->cisco_vlan_ids2names();
  foreach my $vlan_id ( keys %{$id2name} ) {
      printf "Vlan-Id: %4d  => Vlan-Name: %s\n", $vlan_id,
	$id2name->{$vlan_id};
  }

  # show ports for vlan_id
  my $id2port = $session->cisco_vlan_ids2trunk_ports();
  foreach my $vlan_id ( keys %{$id2port} ) {
      printf "Vlan-Id: %4d\n", $vlan_id;
      printf "\tTagged-Ports:     %s\n",
	( join ',', @{ $id2port->{$vlan_id} } );
  }

  # show tagged vlans for port
  my $port2id = $session->cisco_trunk_ports2vlan_ids();
  foreach my $port ( keys %{$port2id} ) {
      printf "Port: %s\n", $port;
      printf "\tVLANs:     %s\n", ( join ',', @{ $port2id->{$port} } );
  }

DESCRIPTION

A mixin class for vlan related infos from the CISCO-VTP-MIB for IEEE-trunks. The mixin-module provides methods for mapping between vlan-ids and vlan-names und relations between trunk-ports and tagged vlan-ids.

MIXIN METHODS

OBJ->cisco_vlan_ids2names()

Returns a hash reference with statically configured vlan-ids as keys and the corresponing vlan-names as values:

{
  vlan_id => vlan_name,
  vlan_id => vlan_name,
  ... ,
}

OBJ->cisco_vlan_ids2trunk_ports()

Returns a hash reference with the vlan-ids as keys and tagged port-lists as values:

{
  vlan_id => [port_list],
  vlan_id => [port_list],
  ... ,
}

OBJ->cisco_trunk_ports2vlan_ids()

Returns a hash reference with the ifIndexes as keys and tagged vlan-ids as values:

{
  ifIndex => [vlan_id_list],
  ifIndex => [vlan_id_list],
  ... ,
}

INITIALIZATION

OBJ->_init($reload)

Fetch basic Cisco-VTP Dot1Q Vlan related snmp values from the host. Don't call this method direct!

PRIVATE METHODS

Only for developers or maintainers.

_fetch_vtp_vlan_tbl_entries($session)

Fetch selected rows from vtpVlanTable during object initialization.

_vtp_vlan_tbl_entries_cb($session)

The callback for _fetch_vtp_vlan_tbl_entries.

_fetch_vtp_vlan_trunk_port_tbl_entries($session)

Fetch selected rows from vlanTrunkPortTable during object initialization.

_vtp_vlan_trunk_port_tbl_entries_cb($session)

The callback for _fetch_vtp_vlan_trunk_port_tbl_entries_cb.

REQUIREMENTS

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