SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $stack = new SNMP::Info(
                    AutoSpecify => 1,
                    Debug       => 1,
                    # These arguments are passed directly on to SNMP::Session
                    DestHost    => 'myswitch',
                    Community   => 'public',
                    Version     => 2
                    ) 
    or die "Can't connect to DestHost.\n";

 my $class = $stack->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

SNMP::Info::NortelStack is a subclass of SNMP::Info that provides an interface to S5-AGENT-MIB and S5-CHASSIS-MIB. These MIBs are used across the Nortel Stackable Ethernet Switches (BayStack), as well as, older Nortel devices such as the Centillion family of ATM switches.

Use or create in a subclass of SNMP::Info. Do not use directly.

Inherited Classes

None.

Required MIBs

S5-AGENT-MIB
S5-CHASSIS-MIB
S5-ROOT-MIB and S5-TCS-MIB are required by the other MIBs.

GLOBAL METHODS

These are methods that return scalar values from SNMP

$stack->os_ver(): Returns the software version extracted from (s5AgInfoVer)
$stack->os_bin(): Returns the firmware version extracted from (s5AgInfoVer)

$stack->tftp_result(): Returns the status of the latest action as shown by $stack->tftp_action().; (s5AgInfoFileStatus)
$stack->ns_auto_pvid(): Returns the value indicating whether adding a port as a member of a VLAN automatically results in its PVID being set to be the same as that VLAN ID.; (s5AgSysAutoPvid)
$stack->tftp_file(): Name of the binary configuration file that will be downloaded/uploaded when the $stack->tftp_action() object is set.; (s5AgSysBinaryConfigFilename)
$stack->tftp_host(): The IP address of the TFTP server for all TFTP operations.; (s5AgSysTftpServerAddress)

$stack->ns_cfg_time(): Returns the value of sysUpTime when the last configuration change (other than attachment changes, or physical additions or removals) in the chassis was detected.; (s5ChasGblConfLstChng)

TABLE METHODS

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

Agent Interface Table (`s5AgMyIfTable`)

$stack->i_cfg_file(): Returns reference to hash. Key: Table entry, Value: Name of the file; (s5AgMyIfCfgFname)

$stack->ns_store_idx(): Returns reference to hash. Key: Table entry, Value: Index of the storage area.; (s5ChasStoreIndx)
$stack->ns_store_type(): Returns reference to hash. Key: Table entry, Value: Type; (s5ChasStoreType)
$stack->ns_store_size(): Returns reference to hash. Key: Table entry, Value: Size; (s5ChasStoreCurSize)
$stack->ns_store_ver(): Returns reference to hash. Key: Table entry, Value: Version; (s5ChasStoreCntntVer)

Pseudo ENTITY-MIB information

These methods emulate ENTITY-MIB Physical Table methods using S5-CHASSIS-MIB.

$stack->ns_e_index(): Returns reference to hash. Key: IID, Value: Integer, Indices are combined into a six digit integer, each index is two digits padded with leading zero if required.
$stack->ns_e_class(): Returns reference to hash. Key: IID, Value: General hardware type (s5ChasGrpDescr).; Group is stripped from the string. Values may be Supervisory Module, Back Plane, Board, Power Supply, Sensor, Fan, Clock, Unit.
$stack->ns_e_descr(): Returns reference to hash. Key: IID, Value: Human friendly name; (s5ChasComDescr)
$stack->ns_e_name(): Returns reference to hash. Key: IID, Value: Human friendly name
$stack->ns_e_hwver(): Returns reference to hash. Key: IID, Value: Hardware version; (s5ChasComVer)
$stack->ns_e_vendor(): Returns reference to hash. Key: IID, Value: nortel
$stack->ns_e_serial(): Returns reference to hash. Key: IID, Value: Serial number; (s5ChasComSerNum)
$stack->ns_e_pos(): Returns reference to hash. Key: IID, Value: The relative position among all entities sharing the same parent.; (s5ChasComSubIndx)
$stack->ns_e_type(): Returns reference to hash. Key: IID, Value: Type of component/sub-component as defined under s5ChasComTypeVal in S5-REG-MIB.

$stack->ns_e_swver(): Returns reference to hash. Key: IID, Value: Software revision.; Value of s5ChasStoreCntntVer for entries with ``flash'' in s5ChasStoreType.
$stack->ns_e_parent(): Returns reference to hash. Key: IID, Value: The value of ns_e_index() for the entity which 'contains' this entity. A value of zero indicates this entity is not contained in any other entity.

Data Munging Callback Subroutines

$stack->munge_ns_grp_type(): Munges s5ChasGrpType into an ENTITY-MIB PhysicalClass equivalent.
