## SYNOPSIS

```
 # Let SNMP::Info determine the correct subclass for you.
 my $c4000 = 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";

## DESCRIPTION

Abstraction subclass for Cisco Catalyst 4000 Layer 2/3 Switches.

### Inherited Classes

- SNMP::Info::Layer3::CiscoSwitch

  - SNMP::Info::MAU

  ### Required MIBs

- Inherited Classes' MIBs

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

  See "Required MIBs" in SNMP::Info::MAU for its own MIB requirements.

## GLOBALS

These are methods that return scalar value from SNMP

### Overrides

- $c4000-\>**fan()**

  Returns fan status

### Globals imported from SNMP::Info::Layer3::CiscoSwitch

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

### Globals imported from SNMP::Info::MAU

See documentation in "GLOBALS" in SNMP::Info::MAU for details.

## TABLE METHODS

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

### Overrides

- $c4000-\>**i\_duplex()**

  Parses mau\_index and mau\_link to return the duplex information for interfaces.

- $c4000-\>**i\_duplex\_admin()**

  Parses `"mac_index"`,`"mau_autostat"`,`"mau_type_admin"` in order to find the admin duplex setting for all the interfaces.

  Returns either (auto,full,half).

- $c4000-\>**i\_speed\_admin()**

  Returns administrative speed for interfaces.

- $c4000-\>set\_i\_speed\_admin(speed, ifIndex)

  Sets port speed, must be supplied with speed and port `"ifIndex"`.

  Speed choices are '10', '100', '1000', 'auto'.

- $c4000-\>set\_i\_duplex\_admin(duplex, ifIndex)

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

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