DESCRIPTION

Provides abstraction to the configuration information obtainable from Juniper (Trapeze) Wireless Controllers through SNMP.

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.

Overrides

$trapeze->i_index(): Returns reference to map of IIDs to Interface index.
Extends "ifIndex" to support thin APs and WLAN virtual interfaces as device interfaces.
$trapeze->interfaces(): Returns reference to map of IIDs to ports. Thin APs are implemented as device interfaces. The thin AP MAC address and Slot ID trapeze_apif_slot() are used as the port identifier.
$trapeze->i_name(): Returns reference to map of IIDs to interface names. Returns "ifName" for Ethernet interfaces and trapeze_ap_name() for thin AP interfaces.
$trapeze->i_description(): Returns reference to map of IIDs to interface types. Returns "ifDescr" for Ethernet interfaces, trapeze_ap_name() for thin AP interfaces.
$trapeze->i_type(): Returns reference to map of IIDs to interface descriptions. Returns "ifType" for Ethernet interfaces and 'capwapWtpVirtualRadio' for thin AP interfaces.
$trapeze->i_up(): Returns reference to map of IIDs to link status of the interface. Returns "ifOperStatus" for Ethernet interfaces and trapeze_apif_admin() for thin AP interfaces.
$trapeze->i_up_admin(): Returns reference to map of IIDs to administrative status of the interface. Returns "ifAdminStatus" for Ethernet interfaces and trapeze_apif_admin() for thin AP interfaces.
$trapeze->i_mac(): Returns reference to map of IIDs to MAC address of the interface. Returns "ifPhysAddress" for Ethernet interfaces.
$trapeze->bp_index(): Simulates bridge MIB by returning reference to a hash mapping i_index() to the interface iid.

$trapeze->fw_mac(): Extracts the MAC from the trapeze_sta_serial() index.

Pseudo ARP Cache Entries

The controller snoops on the MAC->IP mappings. Using this as ARP cache data allows us to get MAC->IP mappings even for stations that only communicate locally. The data is gathered from trapeze_sta_ip().

$trapeze->at_paddr(): Returns reference to hash of Pseudo Arp Cache Entries to MAC address
$trapeze->at_netaddr(): Returns reference to hash of Pseudo Arp Cache Entries to IP Address

$trapeze->e_index(): Returns reference to hash. Key: IID and Value: Integer. The index for APs is created with an integer representation of the last three octets of the AP MAC address.
$trapeze->e_class(): Returns reference to hash. Key: IID, Value: General hardware type. Return ap for wireless access points.
