=head1 DESCRIPTION
|
|
|
|
SNMP::Info::NortelStack is a subclass of SNMP::Info that provides an interface
|
|
to C<S5-AGENT-MIB> and C<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.
