=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $n1600 = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
DestHost => 'myswitch',
|
|
Community => 'public',
|
|
Version => 1
|
|
)
|
|
or die "Can't connect to DestHost.\n";
|
|
|
|
my $class = $n1600->class();
|
|
|
|
print "SNMP::Info determined this device to fall under subclass : $class\n";
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from a Nortel
|
|
N16XX 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.

=head1 GLOBALS
|
|
|

These are methods that return scalar value from SNMP
|
|
|
|

|
|
|
|
Return C<1>. Bulkwalk is currently turned off for this class.

|
=item $n1600->model()
|
|
|
|
Returns model type. Checks $n1600->id() against the
|
|
F<RAPID-CITY-MIB> and then parses out C<rcA>.
|
|
|
|
=item $n1600->vendor()

Returns os version extracted from C<sysDescr>.

|
|
|
|
Required by SNMP::Info::SONMP. Number representing the number of ports
|
|
reserved per slot within the device MIB.
|
|
|
|
Returns 64 since largest switch has 48 ports. Since these switches can
|
|
not stack, the only requirement to reserve more than the max number of ports.

|
|
|
Returns reference to hash of interface names to iids.
|
|
|
|
Places a 1 in front of index number. This is required for compatibility with
|
|
SNMP::Info::SONMP.

Returns reference to hash of interface administrative link duplex status.
