SNMP::Info::Layer2::Baystack - SNMP Interface to Nortel Baystack Switches

|
|
|
|
=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $baystack = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly on to SNMP::Session
|
|
DestHost => 'myswitch',
|
|
Community => 'public',
|
|
Version => 2
|
|
)
|
|
or die "Can't connect to DestHost.\n";

|
|
|
my $class = $baystack->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
|
|
Baystack 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 $baystack->vendor()
|
|
|

Returns 'nortel'

|
|
|
|
Cross references $baystack->id() to the SYNOPTICS-MIB and returns
|
|
the results. 303s and 304s have the same ID, so we have a hack
|
|
to return depending on which it is.

Removes sreg- from the model name

=item $baystack->os()
|

Returns 'baystack' or 'boss' depending on software version.

Returns the firmware version extracted from B<sysDescr>.

=item $baystack->index_factor()
|
|
|
|
Required by SNMP::Info::SONMP. Number representing the number of ports
|
|
reserved per slot within the device MIB.
|
|
|
|
Index factor on the Baystack switches are determined by the formula: Index
|
|
Factor = 64 if (model = 470 or (os eq 'BoSS' and operating in pure mode))
|
|
or else Index factor = 32.
|
|
|
|
Returns either 32 or 64 based upon the formula.

=item $baystack->interfaces()
|
|
|
|
Returns reference to the map between IID and physical Port.
|
|
|
|
Slot and port numbers on the Baystack switches are determined by the formula:
|
|
|
|
port = (Interface index % Index factor)
|
|
slot = (int(Interface index / Index factor)) + Slot offset
|
|
|
|
The physical port name is returned as slot.port.
|
|
|
|
=item $baystack->i_ignore()
|
|
|
|
Returns reference to hash of IIDs to ignore.
|
|
|
|
=item $baystack->i_mac()
|
|
|
|
Returns the B<ifPhysAddress> table entries.
|
|
|
|
Removes all entries matching '00:00:00:00:00:00' -- Certain
|
|
revisions of Baystack firmware report all zeros for each port mac.
|
|
|
|
=item $baystack->i_name()
|
|
|
|
Crosses ifName with ifAlias and returns the human set port name if exists.
