SNMP::Info::Layer3::C3550 - SNMP Interface to Cisco Catalyst 3550 Layer 2/3 Switches running IOS

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 "Cant 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(...);



    Inherited Classes

SNMP::Info::CiscoStack
SNMP::Info::Layer3::CiscoSwitch

    Required MIBs

Inherited Classes’ MIBs See Required MIBs in SNMP::Info::CiscoStack for its own MIB requirements.

See Required MIBs in SNMP::Info::Layer3::CiscoSwitch for its own MIB requirements.

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.

See documentation in GLOBALS in SNMP::Info::CiscoStack for details.

See documentation in GLOBALS in SNMP::Info::Layer3::CiscoSwitch for details.

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, $if_map{FastEthernet0/1})
        or die "Couldnt change port duplex. ",$c3550->error(1);
