TABLE METHODS

78       These are methods that return tables of information in the form of a
79       reference to a hash.
80
81   Overrides
82       Interface Information
83
84       $netscreen->interfaces()
85           Creates a map between the interface identifier (iid) and the
86           physical port name.
87
88           Defaults to "insIfDescr" if available, uses "nsIfName" if not.
89
90       $netscreen->i_description()
91           Description of the interface. Uses "insIfDescr" if available,
92           "nsIfName" if not.
93
94       $netscreen->i_ignore()
95           Returns without defining any interfaces to ignore.
96
97       $netscreen->i_index()
98           Default SNMP IID to Interface index.
99
100           ("nsIfIndex")
101
102       $netscreen->i_lastchange()
103           The value of "sysUpTime" when this port last changed states
104           (up,down), maps from "ifIndex" to "nsIfIndex".
105
106           ("ifLastChange")
107
108       $netscreen->i_mac()
109           MAC address of the interface.  Note this is just the MAC of the
110           port, not anything connected to it.  Uses "nsIfMAC" if available,
111           "ifPhysAddress" if not.
112
113       $netscreen->i_mtu()
114           INTEGER. Interface MTU value, maps from "ifIndex" to "nsIfIndex".
115
116           ("ifMtu")
117
118       $netscreen->i_name()
119           Interface Name field.
120
121           ("nsIfName")
122
123       $netscreen->i_speed()
124           Speed of the link, maps from "ifIndex" to "nsIfIndex".
125
126       $netscreen->i_type()
127           Interface type.  Maps from "ifIndex" to "nsIfIndex".
128
129           ("ifType")
130
131       $netscreen->i_up()
132           Link Status of the interface.  Typical values are 'up' and 'down'.
133
134           ("nsIfStatus")
135
136       $netscreen->i_up_admin()
137           Administrative status of the port.  Checks both "ifAdminStatus" and
138           "nsIfStatus".
139
140       IP Address Table
141
142       Each entry in this table is an IP address in use on this device.
143
144       $netscreen->ip_index()
145           Maps the IP Table to the IID
146
147       $netscreen->ip_table()

160
161       $netscreen->fw_index()
162           Maps the Forwarding Table to the IID
163
164       $netscreen->fw_mac()
165           Returns reference to hash of forwarding table MAC Addresses.
166
167       $netscreen->fw_port()
168           Returns reference to hash of forwarding table entries port
169           interface identifier (IID).
170
171       $netscreen->bp_index()
172           Returns reference to hash of bridge port table entries map back to
173           interface identifier (IID).
174

177           Returns reference to hash.  Maps ARP table entries to Interface
178           IIDs
179
180           If the device doesn't support "ipNetToMediaIfIndex", this will try
181           the proprietary "nsIpArpIfIdx".
182
183       $netscreen->at_paddr()
184           Returns reference to hash.  Maps ARP table entries to MAC
185           addresses.
186
187           If the device doesn't support "ipNetToMediaPhysAddress", this will
188           try the proprietary "nsIpArpMac".
189
190       $netscreen->at_netaddr()
191           Returns reference to hash.  Maps ARP table entries to IP addresses.
192
193           If the device doesn't support "ipNetToMediaNetAddress", this will
194           try the proprietary "nsIpArpIp".
195
196       Wireless Information
197
198       $dot11->i_ssidlist()
199           Returns reference to hash.  SSID's recognized by the radio
200           interface.  Remaps from "ifIndex" to "nsIfIndex".
201
202           ("dot11DesiredSSID")
203
204       $dot11->i_80211channel()
205           Returns reference to hash.  Current operating frequency channel of
