=head1 DESCRIPTION
|
|
|
|
SNMP::Info::EtherLike is a subclass of SNMP::Info that supplies
|
|
access to the ETHERLIKE-MIB used by some Layer 3 Devices such as Cisco routers.
|
|
|
|
See RFC 1398 for more details.
|
|
|
|
Use or create a subclass of SNMP::Info that inherits this one. Do not use directly.
|
|
|
|
=head2 Inherited Classes
|
|
|
|
