SYNOPSIS

#Let SNMP::Info determine the correct subclass for you.
my $bayhub = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $bayhub->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

Provides abstraction to the configuration information obtainable from a Bay hub device through SNMP. Also provides device MAC to port mapping through the proprietary MIB.

For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

my $bayhub = new SNMP::Info::Layer1::Bayhub(...);

Inherited Classes

SNMP::Info::Layer2

SNMP::Info::NortelStack

SNMP::Info::SONMP

Required MIBs

S5-ETHERNET-COMMON-MIB

S5-COMMON-STATS-MIB

Inherited MIBs

See ``Required MIBs'' in SNMP::Info::Layer2 for its MIB requirements.

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

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

GLOBALS

These are methods that return scalar value from SNMP

$bayhub->vendor()

Returns 'avaya'

$bayhub->os()

Returns 'bay_hub'

$bayhub->model()

Cross references $bayhub->id() to the SYNOPTICS-MIB and returns the results.

Removes either Baystack Hub, 5000, or 5005 depending on the model.

Overrides

$bayhub->layers()

Returns 00000011. Class emulates Layer 2 functionality through proprietary MIBs.

$bayhub->index_factor()

Required by SNMP::Info::SONMP. Number representing the number of ports reserved per slot within the device MIB. Returns 256.

$bayhub->slot_offset()

Required by SNMP::Info::SONMP. Offset if slot numbering does not start at 0. Returns 0.

TABLE METHODS

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

Overrides

$bayhub->i_index()

Returns reference to map of IIDs to Interface index.

Since hubs do not support "ifIndex", the interface index is created using the formula (board * 256 + port).

$bayhub->interfaces()

Returns reference to map of IIDs to physical ports.

$bayhub->i_duplex()

Returns half, hubs do not support full duplex.

$bayhub->i_duplex_admin()

Returns half, hubs do not support full duplex.

$bayhub->i_speed()

Returns interface speed.

$bayhub->i_up()

Returns ("s5EnPortLinkStatus") for each port. Translates on/off to up/down.

$bayhub->i_up_admin()

Returns ("s5EnPortPartStatus") for each port.

$bayhub->set_i_up_admin(state, ifIndex)

Sets port state, must be supplied with state and port "ifIndex"

State choices are 'up' or 'down'

Example:
  my %if_map = reverse %{$bayhub->interfaces()};
  $bayhub->set_i_up_admin('down', $if_map{'1.1'}) 
      or die ``Couldn't change port state. '',$bayhub->error(1);

$bayhub->bp_index()

Simulates bridge MIB by returning reference to a hash containing the index for both the keys and values.

$bayhub->fw_port()

Returns reference to map of IIDs of the "S5-COMMON-STATS-MIB::s5CmSNodeTable" to the Interface index.

$bayhub->fw_mac()

("s5CmSNodeMacAddr")

Pseudo ENTITY-MIB Information

These devices do not support ENTITY-MIB. These methods emulate Physical Table methods using S5-CHASSIS-MIB. See ``TABLE METHODS'' in SNMP::Info::NortelStack for details.

$bayhub->e_index()

Returns ns_e_index().

$bayhub->e_class()

Returns ns_e_class().

$bayhub->e_descr()

Returns ns_e_descr().

$bayhub->e_name()

Returns ns_e_name().

$bayhub->e_fwver()

Returns ns_e_fwver().

$bayhub->e_hwver()

Returns ns_e_hwver().

$bayhub->e_parent()

Returns ns_e_parent().

$bayhub->e_pos()

Returns ns_e_pos().

$bayhub->e_serial()

Returns ns_e_serial().

$bayhub->e_swver()

Returns ns_e_swver().

$bayhub->e_type()

Returns ns_e_type().

$bayhub->e_vendor()

Returns ns_e_vendor().
