SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $l2 = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $l2->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
# Let's get some basic Port information
my $interfaces = $l2->interfaces();
my $i_up = $l2->i_up();
my $i_speed = $l2->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::Layer2::* Please read all docs under
SNMP::Info first.
Provides abstraction to the configuration information obtainable from a
Layer2 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 $l2 = new SNMP::Info::Layer2(...);
Inherited Classes
SNMP::Info
SNMP::Info::Bridge
SNMP::Info::Entity
Required MIBs
Inherited Classes
MIBs required by the inherited classes listed above.
MIBs can be found in netdisco-mibs package.
GLOBALS
These are methods that return scalar value from SNMP
Overrides
$l2->model()
Cross references $l2->id() with product IDs in the Cisco MIBs.
For HP devices, removes 'hpswitch' from the name
For Cisco devices, removes c<'sysid'> from the name
$l2->vendor()
Tries to discover the vendor from $l2->model() and
$l2->description()
$l2->serial()
Returns serial number if available through SNMP

Globals imported from SNMP::Info::Bridge

Globals imported from SNMP::Info::Entity
See documentation in "GLOBALS" in SNMP::Info::Entity for details.
TABLE METHODS
These are methods that return tables of information in the form of a
reference to a hash.
Overrides
$l2->interfaces()
Creates a map between the interface identifier (iid) and the
physical port name.
Defaults to "ifDescr" but checks and overrides with "ifName"
$l2->i_ignore()
Returns reference to hash. Increments value of IID if port is to
be ignored.
Ignores ports with "ifType" of loopback, propvirtual, other, and
cpu
