=head1 SYNOPSIS
|
|
|
|
This module is Depricated. Please use Layer2::BayStack instead.
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from a
|
|
Bay 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.

|

|
|
|
|
Bay MIBs can be found on the CD that came with your product.
|
|
|
|
Or, if you still have a service contract they can be downloaded at
|
|
www.nortelnetworks.com
|
|
|
|
They have also been seen at : http://www.inotech.com/mibs/vendor/baynetworks/synoptics/synoptics.asp
|
|
|
|
Or http://www.oidview.com/mibs/detail.html under Synoptics. Check also www.mibdepot.com
|
|
|
|
=head1 GLOBALS
|
|
|
|
These are methods that return scalar value from SNMP
|
|
|
|
=over
|
|
|
|
=item $bay->vendor()
|
|
|
|
Returns 'bay' :)
|
|
|
|
=item $bay->model()
|
|
|
|
Cross references $bay->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 $bay->cdp_id()
|
|
|
|
Returns the IP that the device is sending out for its Nmm topology info.
|
|
|
|
(B<s5EnMsTopIpAddr>)
|
|
|
|
=item $bay->cdp_run()
|
|
|
|
Returns if the S5-ETH-MULTISEG-TOPOLOGY info is on for this device.
|
|
|
|
(B<s5EnMsTopStatus>)

|
|
|
|
=head1 TABLE ENTRIES
|
|
|
|
These are methods that return tables of information in the form of a reference
|
|
to a hash.

|
|
|
=head2 Overrides
|
|
|
|
=over
|
|
|
|
=item $bay->interfaces()
|
|
|
|
Returns reference to map of IIDs to physical ports.
|
|
|
|
Currently simply returns the B<ifIndex>
|
|
|
|
=item $bay->i_ignore()
|
|
|
|
Returns reference to hash of IIDs to ignore.
|
|
|
|
Simply calls the SNMP::Info::Layer2::i_ignore() fn for this.
|
|
|
|
=item $bay->i_mac()
|
|
|
|
Returns the B<ifPhysAddress> table entries.
|
|
|
|
Removes all entries matching '00:00:00:00:00:00' -- Certain
|
|
older revisions of Bay 303 and 304 firmware report all zeros
|
|
for each port mac.
|
|
|
|
=back
|
|
|
|
=head2 Psuedo CDP information
|
|
|
|
All entries with port=0 are local and ignored.
|
|
|
|
=over
|
|
|
|
=item $bay->c_if()
|
|
|
|
Returns referenece to hash. Key: port.1 Value: port (iid)
|
|
|
|
=item $bay->c_ip()
|
|
|
|
Returns referenece to hash. Key: port.1
|
|
|
|
The value of each hash entry can either be a scalar or an array.
|
|
A scalar value is most likely a direct neighbor to that port.
|
|
It is possible that there is a non-bay device in between this device and the remote device.
|
|
|
|
An array value represents a list of seen devices. The only time you will get an array
|
|
of nieghbors, is if there is a non-bay device in between two or more devices.
|
|
|
|
Use the data from the Layer2 Topology Table below to dig deeper.
|
|
|
|
=item $bay->port()
|
|
|
|
Returns reference to hash. Key: port.1 Value: port
|
|

|
Returns reference to hash. Key: port.1 Value: Remote Device Type
