SNMP::Info::Layer3::Foundry - Perl5 Interface to Foundry Network Devices
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This module provides limited functionality from older Foundry devices.
|
|
Specifically designed for a FI4802
|
|
|
|
Data comes RFC1213 and FOUNDRY-SN-ROOT-MIB
|
|
|
|
Inherits all methods from both SNMP::Info and SNMP::Info::Bridge
