# SNMP::Info::Layer3::Scalance(3pm)

SNMP Interface to Siemens Scalance Switches

## NAME

SNMP::Info::Layer3::Scalance - SNMP Interface to Siemens Scalance Switches

## AUTHOR

Christoph Handel

## SYNOPSIS

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

## Change Log

## GLOBALS

These are methods that return scalar value from SNMP

- $scalance-\>**layers()**

  Overwrite snmp value, we support 1-3

- $scalance-\>**os()**

  Returns scalance

- $scalance-\>**vendor()**

  Returns siemens

- $scalance-\>**model()**

  extract a meaningful name from description

- $scalance-\>**mac()**

  use the dot1dBaseBridgeAddress

- $scalance-\>**os\_ver()**

  clean up os\_version string

- $scalance-\>**i\_description()**

  siemens returns a description including firmware, switch serial, etc clean it up. Try to use anything past VLAN or Port. And if this fails  past the last comma

- $scalance-\>**lldp\_ip()**

  simatic does not implement lldpRemManAddrIfSubtype but remote system names are available try to resolve them via DNS and use that

### Globals imported from SNMP::Info::Layer3

See documentation in "GLOBALS" in SNMP::Info::Layer3 for details.

### Globals imported from SNMP::Info::MAU

See documentation in "GLOBALS" in SNMP::Info::MAU for details.

## TABLE METHODS

These are methods that return tables of information in the form of a reference to a hash.

### Overrides

- $scalance-\>**lldp\_ip()**

  Returns reference to hash of ports to remote ips.

  simatic does not implement lldpRemManAddrIfSubtype but remote system names are available try to resolve them via DNS and use that.

### Table Methods imported from SNMP::Info::Layer3

See documentation in "TABLE METHODS" in SNMP::Info::Layer3 for details.

### Table Methods imported from SNMP::Info::MAU

See documentation in "TABLE METHODS" in SNMP::Info::MAU for details.
