NAME

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

AUTHOR

Eric Miller (eric@jeneric.org)

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(...);

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.

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->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)
