=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $dell = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
DestHost => 'myswitch',
|
|
Community => 'public',

|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from an
|
|
Dell Power Connect device through SNMP. D-Link and the IBM BladeCenter
|
|
Gigabit Ethernet Switch Module also use this module based upon MIB support.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not
|
|
after determining a more specific class using the method above.

=item $dell->interfaces()
|
|
|
|
Returns the map between SNMP Interface Identifier (iid) and physical port
|
|
name. Uses name if available instead of description since descriptions are
|
|
sometimes not unique.
|
|
|
|
=item $dell->i_duplex_admin()
|
|
|
|
Returns reference to hash of iid to current link administrative duplex
|
|
setting.
|
|
|
|
=item $dell->fw_mac()
|
|
|
|
Returns reference to hash of forwarding table MAC Addresses.
|
|
|
|
Some devices don't implement the C<BRIDGE-MIB> forwarding table, so we use
|
|
the C<Q-BRIDGE-MIB> forwarding table. Fall back to the C<BRIDGE-MIB> if
|
|
C<Q-BRIDGE-MIB> doesn't return anything.
|
|
|

|
|
|
|
Returns reference to hash of forwarding table entries port interface

|

|
Some devices don't implement the C<BRIDGE-MIB> forwarding table, so we use
|
|
the C<Q-BRIDGE-MIB> forwarding table. Fall back to the C<BRIDGE-MIB> if
