SNMP::Info::Layer7 - SNMP Interface to network devices serving Layer7 only.

# Let SNMP::Info determine the correct subclass for you. my $l7 = new SNMP::Info( AutoSpecify => 1, Debug => 1, DestHost => 'myswitch', Community => 'public', Version => 1 ) or die "Can't connect to DestHost.\n"; my $class = $l7->class(); print "SNMP::Info determined this device to fall under subclass : $class\n"; # Let's get some basic Port information my $interfaces = $l7->interfaces(); my $i_up = $l7->i_up(); my $i_speed = $l7->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"; }
This class is usually used as a superclass for more specific device classes listed under SNMP::Info::Layer7::* Please read all docs under SNMP::Info first.
Provides abstraction to the configuration information obtainable from a Layer7 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 $l7 = new SNMP::Info::Layer7(...);
MIBs required for "Required MIBs" in SNMP::Info
See "Required MIBs" in SNMP::Info for its MIB requirements.
These are methods that return scalar value from SNMP
Cross references $l7->id() with product IDs.
Tries to discover the vendor by looking up the enterprise number in sysObjectID.
sysObjectID
See documentation in "GLOBALS" in SNMP::Info for details.
These are methods that return tables of information in the form of a reference to a hash.
Returns reference to the map between IID and physical Port.
Returns reference to hash. Increments value of IID if port is to be ignored.
Ignores loopback, other, and cpu
See documentation in "TABLE METHODS" in SNMP::Info for details.
