SYNOPSIS

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

DESCRIPTION

Abstraction subclass for routers running Nortel BayRS.

For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

 my $bayrs = new SNMP::Info::Layer3::BayRS(...);

GLOBALS

These are methods that return scalar value from SNMP

$bayrs->model()

Returns the model of the BayRS router. Will translate between the MIB model and the common model with this map :

    C<%MODEL_MAP = ( 
        'acefn'     => 'FN',
        'aceln'     => 'LN',
        'acecn'     => 'CN',
        'afn'       => 'AFN',
        'in'        => 'IN',
        'an'        => 'AN',
        'arn'       => 'ARN',
        'sys5000'   => '5000',
        'freln'     => 'BLN',
        'frecn'     => 'BCN',
        'frerbln'   => 'BLN-2',
        'asn'       => 'ASN',
        'asnzcable' => 'ASN-Z',
        'asnbcable' => 'ASN-B',
        );>
$bayrs->vendor()

Returns 'nortel'

$bayrs->os()

Returns 'bayrs'

$bayrs->os_ver()

Returns the software version extracted from sysDescr

$bayrs->serial()

Returns (wfHwBpSerialNumber) after conversion to ASCII decimal

$bayrs->root_ip()

Returns the primary IP used to communicate with the router.

Returns the first found: CLIP (CircuitLess IP), (wfOspfRouterId), or undefined.

TABLE METHODS

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

Note: These methods do not support partial table fetches, a partial can be passed but the entire table will be returned.

Overrides

$bayrs->interfaces()

Returns reference to the map between IID and physical Port.

The physical port name is stripped to letter and numbers to signify port type and slot port (S11) if the default platform naming was maintained. Otherwise the port is the interface description.

$bayrs->i_name()

Returns (ifDescr) along with VLAN name (wfDot1qTagCfgVlanName) for VLAN interfaces.

$bayrs->i_duplex()

Returns reference to hash. Maps port operational duplexes to IIDs for Ethernet interfaces.

$bayrs->i_duplex_admin()

Returns reference to hash. Maps port admin duplexes to IIDs for Ethernet interfaces.

$bayrs->i_vlan()

Returns reference to hash. Maps port VLAN ID to IIDs.

Pseudo ENTITY-MIB information

These methods emulate ENTITY-MIB Physical Table methods using Wellfleet-HARDWARE-MIB and Wellfleet-MODULE-MIB.

$bayrs->e_index()

Returns reference to hash. Key and Value: Integer. The index is created by combining the slot, module, and position into a five or six digit integer. Slot can be either one or two digits while the module and position are each two digits padded with leading zero if required.

$bayrs->e_class()

Returns reference to hash. Key: IID, Value: General hardware type. This class only returns container and module types.

$bayrs->e_descr()

Returns reference to hash. Key: IID, Value: Human friendly name.

$bayrs->e_name()

Returns reference to hash. Key: IID, Value: Human friendly name.

$bayrs->e_hwver()

Returns reference to hash. Key: IID, Value: Hardware version.

$bayrs->e_vendor()

Returns reference to hash. Key: IID, Value: nortel.

$bayrs->e_serial()

Returns reference to hash. Key: IID, Value: Serial number.

$bayrs->e_pos()

Returns reference to hash. Key: IID, Value: The relative position among all entities sharing the same parent.

$bayrs->e_type()

Returns reference to hash. Key: IID, Value: Type of component/sub-component as defined in Wellfleet-HARDWARE-MIB for processors and link modules or Wellfleet-MODULE-MIB for hardware modules.

$bayrs->e_fwver()

Returns reference to hash. Key: IID, Value: Firmware revision. Only available on processors.

$bayrs->e_swver()

Returns reference to hash. Key: IID, Value: Software revision. Only available on processors.

$bayrs->e_parent()

Returns reference to hash. Key: IID, Value: The value of e_index() for the entity which 'contains' this entity. A value of zero indicates this entity is not contained in any other entity.
