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_index()
95           Default SNMP IID to Interface index.
96
97           ("nsIfIndex")
98
99       $netscreen->i_lastchange()
100           The value of "sysUpTime" when this port last changed states
101           (up,down), maps from "ifIndex" to "nsIfIndex".
102
103           ("ifLastChange")
104
105       $netscreen->i_mac()
106           MAC address of the interface.  Note this is just the MAC of the
107           port, not anything connected to it.  Uses "nsIfMAC" if available,
108           "ifPhysAddress" if not.
109
110       $netscreen->i_mtu()
111           INTEGER. Interface MTU value, maps from "ifIndex" to "nsIfIndex".
112
113           ("ifMtu")
114
115       $netscreen->i_name()
116           Interface Name field.
117
118           ("nsIfName")
119
120       $netscreen->i_speed()
121           Speed of the link, maps from "ifIndex" to "nsIfIndex".
122
123       $netscreen->i_type()
124           Interface type.  Maps from "ifIndex" to "nsIfIndex".
125
126           ("ifType")
127
128       $netscreen->i_up()
129           Link Status of the interface.  Typical values are 'up' and 'down'.
130
131           ("nsIfStatus")
132
133       $netscreen->i_up_admin()
134           Administrative status of the port.  Checks both "ifAdminStatus" and
135           "nsIfStatus".
136
137       IP Address Table
138
139       Each entry in this table is an IP address in use on this device.
140
141       $netscreen->ip_index()
142           Maps the IP Table to the IID
143
144       $netscreen->ip_table()
145           Maps the Table to the IP address
146

152           ("nsIfNetmask")
153
154       Forwarding Table
155
156       Uses "nsIpArpTable" to emulate the forwarding table.
157
158       $netscreen->fw_index()
159           Maps the Forwarding Table to the IID
160
161       $netscreen->fw_mac()
162           Returns reference to hash of forwarding table MAC Addresses.
163
164       $netscreen->fw_port()
165           Returns reference to hash of forwarding table entries port
166           interface identifier (IID).
167
168       $netscreen->bp_index()
169           Returns reference to hash of bridge port table entries map back to
170           interface identifier (IID).
171
172   Arp Cache Table
173       $netscreen->at_index()
174           Returns reference to hash.  Maps ARP table entries to Interface
175           IIDs
176
177           If the device doesn't support "ipNetToMediaIfIndex", this will try
178           the proprietary "nsIpArpIfIdx".
179
180       $netscreen->at_paddr()
181           Returns reference to hash.  Maps ARP table entries to MAC
182           addresses.
183
184           If the device doesn't support "ipNetToMediaPhysAddress", this will
185           try the proprietary "nsIpArpMac".
186
187       $netscreen->at_netaddr()
188           Returns reference to hash.  Maps ARP table entries to IP addresses.
189
190           If the device doesn't support "ipNetToMediaNetAddress", this will
191           try the proprietary "nsIpArpIp".
192
193       Wireless Information
194
195       $dot11->i_ssidlist()
196           Returns reference to hash.  SSID's recognized by the radio
197           interface.  Remaps from "ifIndex" to "nsIfIndex".
198
199           ("dot11DesiredSSID")
200
201       $dot11->i_80211channel()
202           Returns reference to hash.  Current operating frequency channel of
203           the radio interface.  Remaps from "ifIndex" to "nsIfIndex".
