NAME ^

SNMP::Info::Layer1 - SNMP Interface to network devices serving Layer1 only.

AUTHOR ^

Max Baker

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)

Table Methods imported from SNMP::Info

See documentation in "TABLE METHODS" in SNMP::Info for details.
