SYNOPSIS

13           #Let SNMP::Info determine the correct subclass for you.
14
15           my $netscreen = new SNMP::Info(
16                                 AutoSpecify => 1,

20                                 Version     => 2
21                               )

DESCRIPTION

29       Provides abstraction to the configuration information obtainable from a
30       Juniper Netscreen devices through SNMP.
31
32       For speed or debugging purposes you can call the subclass directly, but
33       not after determining a more specific class using the method above.

TABLE METHODS

83       These are methods that return tables of information in the form of a
84       reference to a hash.
85
86   Overrides
87       Interface Information
88
89       $netscreen->interfaces()
90           Creates a map between the interface identifier (iid) and the
91           physical port name.
92
93           Defaults to "insIfDescr" if available, uses "nsIfName" if not.
94
95       $netscreen->i_description()
96           Description of the interface. Uses "insIfDescr" if available,
97           "nsIfName" if not.
98
99       $netscreen->i_ignore()
100           Returns without defining any interfaces to ignore.
101
102       $netscreen->i_index()
103           Default SNMP IID to Interface index.
104
105           ("nsIfIndex")
106
107       $netscreen->i_lastchange()
108           The value of "sysUpTime" when this port last changed states
109           (up,down), maps from "ifIndex" to "nsIfIndex".
110
111           ("ifLastChange")
112
113       $netscreen->i_mac()
114           MAC address of the interface.  Note this is just the MAC of the
115           port, not anything connected to it.  Uses "nsIfMAC" if available,
116           "ifPhysAddress" if not.
117
118       $netscreen->i_mtu()
119           INTEGER. Interface MTU value, maps from "ifIndex" to "nsIfIndex".
120
121           ("ifMtu")
122
123       $netscreen->i_name()
124           Interface Name field.
125
126           ("nsIfName")
127
128       $netscreen->i_speed()
129           Speed of the link, maps from "ifIndex" to "nsIfIndex".
130
131       $netscreen->i_type()
132           Interface type.  Maps from "ifIndex" to "nsIfIndex".
133
134           ("ifType")
135
136       $netscreen->i_up()
137           Link Status of the interface.  Typical values are 'up' and 'down'.
138
139           ("nsIfStatus")
140
141       $netscreen->i_up_admin()
142           Administrative status of the port.  Checks both "ifAdminStatus" and
143           "nsIfStatus".
144
145       IP Address Table
146
147       Each entry in this table is an IP address in use on this device.
148
149       $netscreen->ip_index()
150           Maps the IP Table to the IID
151

170           Returns reference to hash of forwarding table MAC Addresses.
171
172       $netscreen->fw_port()
173           Returns reference to hash of forwarding table entries port

175
176       $netscreen->bp_index()
177           Returns reference to hash of bridge port table entries map back to

197
198           If the device doesn't support "ipNetToMediaNetAddress", this will
199           try the proprietary "nsIpArpIp".

202
203       $dot11->i_ssidlist()
204           Returns reference to hash.  SSID's recognized by the radio
