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
- SNMP::Info::LLDP
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 SNMPOverrides
- $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

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"
