SYNOPSIS

# 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
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $c3550->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

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 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.

 my $c3550 = new SNMP::Info::Layer3::C3550(...);

GLOBALS

These are methods that return scalar value from SNMP

$c3550->vendor()

Returns 'cisco'

$c3550->model()

Will take the translated model number and try to format it better.

 355048 -> 3550-48
 355012G -> 3550-12G

$c3550->ports()

Tries to cull the number of ports from the model number.

TABLE METHODS

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

Overrides

$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 SNMP::Info::Etherlike for el_duplex() method and SNMP::Info::CiscoStack for its i_duplex() method.

$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 SNMP::Info::CiscoStack for its i_duplex() and p_duplex() methods.

$c3550->set_i_duplex_admin(duplex, ifIndex)

Sets port duplex, must be supplied with duplex and port "ifIndex".

Speed choices are 'auto', 'half', 'full'.

Crosses $c3550->p_port() with $c3550->p_duplex() to utilize port "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);
