|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $c3550 = new SNMP::Info(
|
|
AutoSpecify => 1,
|

Debug => 1,

# These arguments are passed directly to SNMP::Session

|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Abstraction subclass for Cisco Catalyst 3550 Layer 2/3 Switches.
|
|
|
|
These devices run IOS but have some of the same characteristics as the
|
|
Catalyst WS-C family (5xxx,6xxx). For example, forwarding tables are held in
|
|
VLANs, and extended interface information is gleaned from F<CISCO-SWITCH-MIB>.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not
|
|
after determining a more specific class using the method above.

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

|
|
=head2 Overrides
|
|
|
|
=over
|
|
|
|
=item $c3550->i_duplex()
|
|
|
|
Returns reference to hash of iid to current link duplex setting.
|
|
|
|
Software version 12.1(22)EA1a or greater returns duplex based upon the
|
|
result of $c3550->el_duplex(). Otherwise it uses the result of
|
|
the call to CiscoStack::i_duplex().
|
|
|
|
See L<SNMP::Info::Etherlike> for el_duplex() method and
|
|
L<SNMP::Info::CiscoStack> for its i_duplex() method.
|
|
|
|
=item $c3550->i_duplex_admin()
|
|
|
|
Returns reference to hash of iid to administrative duplex setting.
|
|
|
|
Software version 12.1(22)EA1a or greater returns duplex based upon the
|
|
result of $c3550->p_duplex(). Otherwise it uses the result of
|
|
the call to CiscoStack::i_duplex().
|
|
|
|
See L<SNMP::Info::CiscoStack> for its i_duplex() and p_duplex() methods.
|
|
|
|
=item $c3550->set_i_duplex_admin(duplex, ifIndex)
|
|
|
|
Sets port duplex, must be supplied with duplex and port C<ifIndex>.
|
|
|
|
Speed choices are 'auto', 'half', 'full'.
|
|
|
|
Crosses $c3550->p_port() with $c3550->p_duplex() to utilize port C<ifIndex>.
|
|
|
|
Example:
|
|
my %if_map = reverse %{$c3550->interfaces()};
|
|
$c3550->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'})
|
|
or die "Couldn't change port duplex. ",$c3550->error(1);
