NAME
SNMP::Info::Layer2 - SNMP Interface to network devices serving Layer2 only.AUTHOR
Max BakerSYNOPSIS
# 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::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 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"
- $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
