## SYNOPSIS

```
 # Let SNMP::Info determine the correct subclass for you.
 my $cisco = new SNMP::Info(
                        AutoSpecify => 1,
                        Debug       => 1,
                        # These arguments are passed directly to SNMP::Session
                        DestHost    => 'myswitch',
                        Community   => 'public',
                        Version     => 2
                        )
    or die "Can't connect to DestHost.\n";
 my $class      = $cisco->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";
```

## GLOBALS

These are methods that return scalar value from SNMP

- $cisco-\>**eigrp\_id()**

  (`"cEigrpAsRouterId"`)

- $switch-\>**cisco\_comm\_indexing()**

  Returns 1 when the device is likely to need vlan indexing. Determined by checking `"vtpVersion"`.
