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
                    )

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 Avaya/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.

    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.
