=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $c6500 = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly to SNMP::Session
|
|
DestHost => 'myswitch',

|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Abstraction subclass for Cisco Catalyst 6500 Layer 2/3 Switches.
|
|
|
|
These devices run IOS but have some of the same charactersitics as the Catalyst
|
|
WS-C family (5xxx). For example, forwarding tables are held in VLANs, and
|
|
extended interface information is gleened from 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.

=head1 TABLE METHODS
|
|
|
|
These are methods that return tables of information in the form of a reference
|
|
to a hash.
|
|
|
|
=head2 Overrides
|
|
|
|
=over
|
|
|
|
=item $c6500->i_duplex()
|
|
|
|
Returns reference to hash of iid to current link duplex setting.
|
|
|
|
Newer software versions return duplex based upon the result of
|
|
$c6500->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 $c6500->i_duplex_admin()
|
|
|
|
Returns reference to hash of iid to administrative duplex setting.
|
|
|
|
Newer software versions return duplex based upon the result of
|
|
$c6500->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 $c6500->set_i_duplex_admin(duplex, ifIndex)
|
|
|
|
Sets port duplex, must be supplied with duplex and port ifIndex.
|
|
|
|
Speed choices are 'auto', 'half', 'full'.
|
|
|
|
Crosses $c6500->p_port() with $c6500->p_duplex() to utilize port ifIndex.
|
|
|
|
Example:
|
|
my %if_map = reverse %{$c6500->interfaces()};
|
|
$c6500->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'})
|
|
or die "Couldn't change port duplex. ",$c6500->error(1);
