|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#Let SNMP::Info determine the correct subclass for you.
|
|
|
|
my $cyclades = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly to SNMP::Session
|
|
DestHost => 'myswitch',
|
|
Community => 'public',
|
|
Version => 2
|
|
)
|
|
|
|
or die "Can't connect to DestHost.\n";
|
|
|
|
my $class = $cyclades->class();
|
|
print "SNMP::Info determined this device to fall under subclass : $class\n";
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from a
|
|
Cyclades device through SNMP.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not
|
|
after determining a more specific class using the method above.

=item $cyclades->i_index()
|
|
|
|
Returns reference to map of IIDs to Interface index.
|
|
|
|
Extended to include serial ports. Serial ports are indexed with the
|
|
alternative labeling system for the serial port, the listening socket port
|
|
B<cySPortSocketPort> to avoid conflicts with B<ifIndex>.
|
|
|
|
=item $cyclades->interfaces()

Returns reference to map of IIDs to physical ports. Extended to include

|
serial ports, B<cyISPortTty>.
|
|
|
|
=item $cyclades->i_speed()
|
|
|
|
Returns interface speed. Extended to include serial ports, B<cyISPortSpeed>.
|
|
|
|
=item $cyclades->i_up()
|
|
|
|
Returns link status for each port. Extended to include serial ports,
|
|
B<cyISPortSigCD>.
|
|
|
|
=item $cyclades->i_description()
|
|
|
|
Returns description of each port. Extended to include serial ports,
|
|
B<cyISPortName>.
|
