SNMP::Info::Layer1(3pm)

Usage

 # Let SNMP::Info determine the correct subclass for you.
 my $l1 = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        )
    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";
 }

Overview

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 "REQUIREMENTS" in SNMP::Info

See "REQUIREMENTS" in SNMP::Info for its MIB requirements.

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 "USAGE" 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")
