NAME

SNMP::Info::Layer1::Bayhub - SNMP Interface to Bay / Nortel Hubs

AUTHOR

Eric Miller

SYNOPSIS

     #Let SNMP::Info determine the correct subclass for you.
 
     my $bayhub = 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 = $bayhub->class();
     print "SNMP::Info determined this device to fall under subclass : $class\n";
 
 

DESCRIPTION

Provides abstraction to the configuration information obtainable from a Bayhub device through SNMP. Also provides device MAC to port mapping through the propietary 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::SONMP

Required MIBs

S5-ETHERNET-COMMON-MIB

S5-COMMON-STATS-MIB

Inherited Classes' MIBs

See SNMP::Info for its own MIB requirements.

See SNMP::Info::Bridge for its own MIB requirements.

See SNMP::Info::NortelStack for its own MIB requirements.

See SNMP::Info::SONMP for its own MIB requirements.

GLOBALS

These are methods that return scalar value from SNMP

$bayhub->vendor()

Returns 'nortel'

$bayhub->os()

Returns 'bay_hub'

$bayhub->model()

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

Removes sreg- from the model name

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.

Global Methods imported from SNMP::Info::SONMP

TABLE ENTRIES

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()

Currently returns 10 Mbps. The class does not currently support 100 Mbps hubs.

$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)
