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(...);

MIBs required for ``Required MIBs'' in SNMP::Info
See ``Required MIBs'' 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 ``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")
