SNMP::Info::Layer2::Bay - SNMP Interface to old Bay Network BayStack Switches

This module is Depricated. Please use Layer2::BayStack instead.

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.

 my $bay = new SNMP::Info::Layer2::Bay(...);

SYNOPTICS-ROOT-MIB
S5-ETH-MULTISEG-TOPOLOGY-MIB
Inherited classes: MIBs required by SNMP::Info::Layer2 and its superclasses.

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

Or http://www.oidview.com/mibs/detail.html under Synoptics. Check also www.mibdepot.com

These are methods that return scalar value from SNMP

$bay->vendor(): Returns 'bay' :)
$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
$bay->cdp_id(): Returns the IP that the device is sending out for its Nmm topology info.; (s5EnMsTopIpAddr)
$bay->cdp_run(): Returns if the S5-ETH-MULTISEG-TOPOLOGY info is on for this device.; (s5EnMsTopStatus)

See documentation in SNMP::Info::Layer2 for details.

These are methods that return tables of information in the form of a reference to a hash.

$bay->interfaces(): Returns reference to map of IIDs to physical ports.; Currently simply returns the ifIndex
$bay->i_ignore(): Returns reference to hash of IIDs to ignore.; Simply calls the SNMP::Info::Layer2::i_ignore() fn for this.
$bay->i_mac(): Returns the 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.

All entries with port=0 are local and ignored.

$bay->c_if(): Returns referenece to hash. Key: port.1 Value: port (iid)
$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.
$bay->port(): Returns reference to hash. Key: port.1 Value: port
$bay->platform(): Returns reference to hash. Key: port.1 Value: Remote Device Type

$bay->bay_topo_slot(): Returns reference to hash. Key: Table entry, Value:slot number; (s5EnMsTopNmmSlot)
$bay->bay_topo_port(): Returns reference to hash. Key: Table entry, Value:Port Number (interface iid); (s5EnMsTopNmmPort)
$bay->bay_topo_ip(): Returns reference to hash. Key: Table entry, Value:Remote IP address of entry; (s5EnMsTopNmmIpAddr)
$bay->bay_topo_seg(): Returns reference to hash. Key: Table entry, Value:Remote Segment ID; (s5EnMsTopNmmSegId)
$bay->bay_topo_mac (s5EnMsTopNmmMacAddr): Returns reference to hash. Key: Table entry, Value:Remote MAC address
$bay->bay_topo_platform: Returns reference to hash. Key: Table entry, Value:Remote Device Type; (s5EnMsTopNmmChassisType)
$bay->bay_topo_localseg: Returns reference to hash. Key: Table entry, Value:Boolean, if bay_topo_seg() is local; (s5EnMsTopNmmLocalSeg)
