AUTHOR

Eric Miller

SYNOPSIS

    my $aruba = new SNMP::Info(
			  AutoSpecify => 1,
			  Debug       => 1,
			  DestHost    => 'myswitch',
			  Community   => 'public',
			  Version     => 2
			)

    or die "Can't connect to DestHost.\n";

    my $class = $aruba->class();
    print " Using device sub class : $class\n";

DESCRIPTION

SNMP::Info::Layer3::Aruba is a subclass of SNMP::Info that provides an interface to Aruba wireless switches. The Aruba platform utilizes intelligent wireless switches which control thin access points. The thin access points themselves are unable to be polled for end station information.

This class emulates bridge functionality for the wireless switch. This enables end station MAC addresses collection and correlation to the thin access point the end station is using for communication.

Human-entered name for vlans.

$aruba->i_vlan()

Returns reference to map of IIDs to VLAN ID of the interface.

$aruba->i_vlan_membership()

Returns reference to hash of arrays: key = ifIndex, value = array of VLAN IDs. These are the VLANs for which the port is a member.

$aruba->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.

$aruba->bp_index()

Augments the bridge MIB by returning reference to a hash containing the index mapping of BSSID to device port (AP).

$aruba->fw_port()

Augments the bridge MIB by including the BSSID a wireless end station is communicating through (nUserApBSSID).

$aruba->fw_mac()

Augments the bridge MIB by including the wireless end station MAC (nUserApBSSID) as extracted from the IID.

$aruba->qb_fw_vlan()

Augments the bridge MIB by including wireless end station VLANs (nUserCurrentVlan).

Pseudo ENTITY-MIB information

These methods emulate ENTITY-MIB Physical Table methods using WLSX-WLAN-MIB and WLSX-SYSTEMEXT-MIB. APs are included as subcomponents of the wireless controller.

$aruba->e_index()

Power Over Ethernet Port Table

Creates an index of module.port to align with the indexing of the wlsxPsePortTable with a value of ifIndex. The module defaults 1 if otherwise unknown.

Arp Cache Table Augmentation

The controller has knowledge of MAC->IP mappings for wireless clients. Augmenting the arp cache data with these MAC->IP mappings enables visibility for stations that only communicate locally. We also capture the AP MAC->IP mappings.

$aruba->at_paddr()

Adds MAC addresses extracted from the index of nUserApBSSID.

$aruba->at_netaddr()

Adds IP addresses extracted from the index of nUserApBSSID.
