=head1 DESCRIPTION
|
|
|
|
SNMP::Info::EtherLike is a subclass of SNMP::Info that supplies
|
|
access to the F<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.
