SYNOPSIS¶

    my $aruba = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',

                          Version     => 2
                        )

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. For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

 my $aruba = new SNMP::Info::Layer3::Aruba(...);

$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¶

These methods emulate the POWER-ETHERNET-MIB Power Source Entity (PSE) Port Table "pethPsePortTable" methods using the WLSX-POE-MIB Power over Ethernet Port Table "wlsxPsePortTable".

$aruba->peth_port_ifindex()

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.

$aruba->peth_port_admin()

Administrative status: is this port permitted to deliver power?

"wlsxPsePortAdminStatus"

$aruba->peth_port_status()

Current status: is this port delivering power.

$aruba->peth_port_class()

Device class: if status is delivering power, this represents the 802.3af class of the device being powered.

$aruba->peth_port_neg_power()

The power, in milliwatts, that has been committed to this port. This value is derived from the 802.3af class of the device being powered.

$aruba->peth_port_power()

Power Over Ethernet Module Table¶

These methods emulate the POWER-ETHERNET-MIB Main Power Source Entity (PSE) Table "pethMainPseTable" methods using the WLSX-POE-MIB Power over Ethernet Port Table "wlsxPseSlotTable".

$aruba->peth_power_consumption()

How much power, in watts, this power supply has been committed to deliver.

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".
