NAME

SNMP::Info::Layer2::Baystack - SNMP Interface to Avaya Ethernet Switch (Baystack) and VSP 7000 series switches

SYNOPSIS



 # Let SNMP::Info determine the correct subclass for you.
 my $baystack = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => myswitch,
                          Community   => public,
                          Version     => 2
                        )
  or die "Cant connect to DestHost.\n";

 my $class = $baystack->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";



DESCRIPTION

Provides abstraction to the configuration information obtainable from an Avaya Ethernet Switch (formerly Nortel/Bay Baystack) and VSP 7000 series 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 $baystack = new SNMP::Info::Layer2::Baystack(...);

    Inherited Classes

SNMP::Info::SONMP
SNMP::Info::NortelStack
SNMP::Info::RapidCity
SNMP::Info::LLDP
SNMP::Info::Layer3

    Required MIBs

BAY-STACK-PETH-EXT-MIBB

    Inherited MIBs

See Required MIBs in SNMP::Info::SONMP for its MIB requirements.

See Required MIBs in SNMP::Info::NortelStack for its MIB requirements.

See Required MIBs in SNMP::Info::RapidCity for its MIB requirements.

See Required MIBs in SNMP::Info::LLDP for its MIB requirements.

See Required MIBs in SNMP::Info::Layer3 for its MIB requirements.

GLOBALS

These are methods that return scalar value from SNMP
$baystack->vendor() Returns ’avaya’
$baystack->model() 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.

Returns BPS for Business Policy Switch

For others extracts and returns the switch numeric designation.

$baystack->os() Returns ’baystack’ or ’boss’ depending on software version.
$baystack->os_bin() Returns the firmware version extracted from sysDescr.
$baystack->stp_ver() Returns the particular STP version running on this device.

Values: nortelStpg, pvst, rstp, mstp, ieee8021d

(s5AgSysSpanningTreeOperMode)

    Overrides

$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.

TABLE METHODS

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

    Overrides

$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.



$baystack->i_ignore() Returns reference to hash of IIDs to ignore.
$baystack->i_mac() Returns the 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.

$baystack->i_name() Crosses ifName with ifAlias and returns the human set port name if exists.
$baystack->peth_port_ifindex() Maps the pethPsePortTable to ifIndex by way of the ENTITY-MIB.
$baystack->peth_port_power() Power supplied by PoE ports, in milliwatts

(bspePethPsePortExtMeasuredPower)

ENTITY-MIB Information

For older devices which do not support ENTITY-MIB, these methods emulate Physical Table methods using S5-CHASSIS-MIB. See TABLE METHODS in SNMP::Info::NortelStack for details on ns_e_* methods.
$baystack->e_index() If the device doesn’t support entPhysicalDescr, this will try ns_e_index(). Note that this is based on entPhysicalDescr due to implementation details of SNMP::Info::Entity::e_index().
$baystack->e_class() If the device doesn’t support entPhysicalClass, this will try ns_e_class().
$baystack->e_descr() If the device doesn’t support entPhysicalDescr, this will try ns_e_descr().
$baystack->e_name() If the device doesn’t support entPhysicalName, this will try ns_e_name().
$baystack->e_fwver() If the device doesn’t support entPhysicalFirmwareRev, this will try ns_e_fwver().
$baystack->e_hwver() If the device doesn’t support entPhysicalHardwareRev, this will try ns_e_hwver().
$baystack->e_parent() If the device doesn’t support entPhysicalContainedIn, this will try ns_e_parent().
$baystack->e_pos() If the device doesn’t support entPhysicalParentRelPos, this will try ns_e_pos().
$baystack->e_serial() If the device doesn’t support entPhysicalSerialNum, this will try ns_e_serial().
$baystack->e_swver() If the device doesn’t support entPhysicalSoftwareRev, this will try ns_e_swver().
$baystack->e_type() If the device doesn’t support entPhysicalVendorType, this will try ns_e_type().
$baystack->e_vendor() If the device doesn’t support entPhysicalMfgName, this will try ns_e_vendor().

    Layer 2 Forwarding Database

These methods try to obtain the layer 2 forwarding database entries via the normal bridge methods as well as SPBM entries via rapid city methods.
$baystack->fw_mac() Returns reference to hash of forwarding table MAC Addresses
$baystack->fw_port() Returns reference to hash of forwarding table entries port interface identifier (iid)
$baystack->qb_fw_vlan() Returns reference to hash of forwarding table entries VLAN ID
$baystack->fw_status() Returns reference to hash of forwarding table entries status
