# SNMP::Info::Layer3::CiscoSwitch(3pm)

Base class for L3 Cisco switches

## NAME

SNMP::Info::Layer3::CiscoSwitch - Base class for L3 Cisco switches

## AUTHOR

Eric Miller

## SYNOPSIS

```
 # Let SNMP::Info determine the correct subclass for you.
 my $switch = 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      = $switch->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";
```

## DESCRIPTION

Base subclass for Cisco Layer 2/3 Switches.

These devices have switch specific characteristics beyond those in traditional routers covered by SNMP::Info::Layer3::Cisco. For example, port security interface information from SNMP::Info::CiscoPortSecurity.

For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

```
 my $swich = new SNMP::Info::Layer3::CiscoSwitch(...);
```
