 | |
| =head1 Class Variables (options)
 | |
| 
 | |
| =over
 | |
| 
 | |
| =item $SNMP::Info::Layer3::Altiga::int_include_vpn
 | |
| 
 | |
| Variable to modify behavior of "interfaces" subroutine.
 | |
| 
 | |
|   * When set to 0, "interfaces" returns only fixed interfaces from the IF-MIB,
 | |
|   * When set to 1, "interfaces" returns fixed interfaces from IF-MIB and
 | |
|     LAN-to-LAN tunnels from ALTIGA-SESSION-MIB (default)
 | |
| 
 | |
| =back
 | |
| 
 | |
| =head1 GLOBALS
 | |
| 
 | |
| These are methods that return scalar value from SNMP
 | |
| 
 | |

 | |

 | |
|

| Returns 'altiga'
 | |
| 
 | |
| =item $altiga->os_ver()
 | |
| 
 | |
| Tries to determine OS version from the C<sysDescr.0> field. Returns version or C<sysDescr.0>
 | |
| 
 | |
| =item $altiga->fan()
 | |
| 
 | |
| Combines results from C<fan1_alarm>, C<fan2_alarm>, and C<fam3_alarm> methods.
 | |
| 
 | |
| =item $altiga->ps1_status()
 | |
| 
 | |
| Combines C<ps1_3v_alarm> and C<ps1_5v_alarm> methods.

| =head1 TABLE METHODS
 | |
| 
 | |
| These are methods that return tables of information in the form of a reference
 | |
| to a hash.
 | |
| 
 | |
| =over
 | |
| 
 | |
| =item $altiga->interfaces()
 | |
| 
 | |
| This method overrides the interfaces() method inherited from SNMP::Info.
 | |
| It provides a mapping between the Interface Table Index (iid) and the physical 
 | |
| port name, adding a port number to the port name to prevent duplicate names.
 | |
