=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $c2900 = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly on to SNMP::Session
|
|
DestHost => 'myswitch',
|
|
Community => 'public',
|
|
Version => 2
|
|
)
|
|
or die "Can't connect to DestHost.\n";
|
|
|
|
my $class = $c2900->class();
|
|
print "SNMP::Info determined this device to fall under subclass : $class\n";
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from a
|
|
C2900 device through SNMP.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not after determining
|
|
a more specific class using the method above.
|

=head1 TABLE ENTRIES
|
|
|
|
These are methods that return tables of information in the form of a reference
|
|
to a hash.

|

|
|
|
|
=item $c2900->interfaces()
|
|
|
|
Returns reference to the map between IID and physical Port.
|
|
|
|
On the 2900 devices i_name isn't reliable, so we override to just the description.
|
|
|
|
Next all dots are changed for forward slashes so that the physical port name
|
|
is the same as the broadcasted CDP port name.
|
|
(Ethernet0.1 -> Ethernet0/1)
|
|
|
|
Also, any weird characters are removed, as I saw a few pop up.
|
|
|
|
=item $c2900->i_duplex()
|
|
|
|
Returns reference to map of IIDs to current link duplex
|

|
|
=item $c2900->i_duplex_admin()
|
|
|
|
Returns reference to hash of IIDs to admin duplex setting
