only.

SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $l1 = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 1
)
or die "Can't connect to DestHost.\n";
my $class = $l1->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
# Let's get some basic Port information
my $interfaces = $l1->interfaces();
my $i_up = $l1->i_up();
my $i_speed = $l1->i_speed();
foreach my $iid (keys %$interfaces) {
my $port = $interfaces->{$iid};
my $up = $i_up->{$iid};
my $speed = $i_speed->{$iid}
print "Port $port is $up. Port runs at $speed.\n";
}
DESCRIPTION
This class is usually used as a superclass for more specific device
classes listed under SNMP::Info::Layer1::* Please read all docs under
SNMP::Info first.
Provides abstraction to the configuration information obtainable from a
Layer1 device through SNMP. Information is stored in a number of MIBs.
For speed or debugging purposes you can call the subclass directly, but
not after determining a more specific class using the method above.
my $l1 = new SNMP::Info::Layer1(...);
Inherited Classes
SNMP::Info
Required MIBs
SNMP-REPEATER-MIB
MIBs required for "Required MIBs" in SNMP::Info
See "Required MIBs" in SNMP::Info for its MIB requirements.
SNMP-REPEATER-MIB needs to be extracted from
ftp://ftp.cisco.com/pub/mibs/v1/v1.tar.gz
GLOBALS
These are methods that return scalar value from SNMP
$l1->ports_managed()
Gets the number of ports under the interface mib
("ifNumber")
Overrides
$l1->model()
Cross references $l1->id() with product IDs.
For HP devices, removes 'hpswitch' from the name
For Cisco devices, removes 'sysid' from the name
$l1->vendor()
Tries to discover the vendor from $l1->model() and $l1->vendor()
$l1->ports()
Adds the values from rptr_ports() and ports_managed()
$l1->slots()
Number of 'groups' in the Repeater MIB
("rptrGroupCapacity")
Global Methods imported from SNMP::Info
See documentation in "GLOBALS" in SNMP::Info for details.
TABLE METHODS
These are methods that return tables of information in the form of a
reference to a hash.
Overrides
$l1->interfaces()
Returns reference to the map between IID and physical Port.
$l1->i_up()
Returns reference to map of IIDs to link status.
$l1->i_up_admin()
Returns reference to map of IIDs to administrative link status.
Repeater MIB
$l1->rptr_ports()
Number of ports in each group.
("rptrGroupPortCapacity")
$l1->rptr_port()
Port number in Group
("rptrPortIndex")
$l1->rptr_slot()
Group (slot) Number for given port.
("rptrPortGroupIndex")
$l1->rptr_up_admin()
("rptrPortAdminStatus")
$l1->rptr_up()
("rptrPortOperStatus")
$l1->rptr_last_src()
("rptrAddrTrackNewLastSrcAddress")
