=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $n1600 = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly on to SNMP::Session
|
|
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.

See classes listed above for their required MIBs.

MIBs can be found on the CD that came with your product.
|
|
|
|
Or, they can be downloaded directly from Nortel regardless of support
|
|
contract status.

|
Go to http://www.nortel.com Techninal Support, Browse Technical Support,
|

After installation, all mibs are located under the install directory under mibs
|
|
and the repspective product line.

=head1 GLOBALS
|
|
|
|
These are methods that return scalar value from SNMP
|
|
|
|
=over
|
|
|
|
=item $n1600->bulkwalk_no
|
|
|
|
Return C<1>. Bulkwalk is currently turned off for this class.
|
|
|
|
=item $n1600->model()
|
|
|
|
Returns model type. Checks $n1600->id() against the
|
|
RAPID-CITY-MIB and then parses out rcA.
|
|
|
|
=item $n1600->vendor()
|
|
|
|
Returns 'nortel'
|
|
|
|
=item $n1600->os()
|
|
|

Returns 'passport'

|
|
|
|
=item $n1600->index_factor()
|
|
|
|
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 requirment to reserve more than the max number of ports.

=head1 TABLE METHODS
|
|
|

|
to a hash.

|
=item $n1600->interfaces()
|
|
|
|
Returns reference to hash of interface names to iids.
|
|
|
|
Places a 1 in front of index number. This is required for compatibilty with
|
|
SNMP::Info::SONMP.
|
|
|
|
=item $n1600->i_duplex()
|
|
|
|
Returns reference to hash of interface operational link duplex status.
|
|
|

=item $n1600->i_duplex_admin()
|
|
|
|
Returns reference to hash of interface administrative link duplex status.
