NAME

SNMP::Info::Layer3::Enterasys - SNMP Interface to Enterasys Network Devices

AUTHOR

Eric Miller

SYNOPSIS

  # Let SNMP::Info determine the correct subclass for you. 
  my $enterasys = new SNMP::Info(
                           AutoSpecify => 1,
                           Debug       => 1,
                           # These arguments are passed directly on to SNMP::Session
                           DestHost    => 'myswitch',
                           Community   => 'public',
                           Version     => 1
                         ) 
     or die "Can't connect to DestHost.\n";
 
 

  my $class = $enterasys->class();
 
 

  print "SNMP::Info determined this device to fall under subclass : $class\n";
 
 

DESCRIPTION

Provides abstraction to the configuration information obtainable from an Enterasys device through SNMP.

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

my $enterasys = new SNMP::Info::Layer3::Enterasys(...);

Inherited Classes

SNMP::Info::MAU

SNMP::Info::LLDP

SNMP::Info::CDP

SNMP::Info::Layer3

Required MIBs

ENTERASYS-OIDS-MIB

Inherited MIBs

See ``Required MIBs'' in SNMP::Info::MAU for its MIB requirements.

See ``Required MIBs'' in SNMP::Info::LLDP for its MIB requirements.

See ``Required MIBs'' in SNMP::Info::CDP for its MIB requirements.

See ``Required MIBs'' in SNMP::Info::Layer3 for its MIB requirements.

GLOBALS

These are methods that return scalar value from SNMP

$enterasys->model()

Returns model type. Checks $enterasys->id() against the ENTERASYS-OIDS-MIB.

$enterasys->vendor()

Returns enterasys

$enterasys->os()

Returns enterasys

$enterasys->mac()

Returns base mac

(dot1dBaseBridgeAddress)

Overrides

Globals imported from SNMP::Info::MAU

See documentation in ``GLOBALS'' in SNMP::Info::MAU for details.

Globals imported from SNMP::Info::LLDP

See documentation in ``GLOBALS'' in SNMP::Info::LLDP for details.

Globals imported from SNMP::Info::CDP

See documentation in ``GLOBALS'' in SNMP::Info::CDP for details.

Globals imported from SNMP::Info::Layer3

See documentation in ``GLOBALS'' in SNMP::Info::Layer3 for details.

TABLE METHODS

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

Overrides

$enterasys->i_ignore()

Returns reference to hash. Creates a key for each IID that should be ignored.

Currently looks for rs232, tunnel,loopback,lo,null from $enterasys->interfaces()

$enterasys->i_duplex()

See documentation for mau_i_duplex() in ``TABLE METHODS'' in SNMP::Info::MAU.

$enterasys->i_duplex_admin()

See documentation for mau_i_duplex_admin() in ``TABLE METHODS'' in SNMP::Info::MAU.

Topology information

Based upon the firmware version Enterasys devices may support Cabletron Discovery Protocol (CTRON-CDP), Cisco Discovery Protocol (CDP), Link Layer Discovery Protocol (LLDP), or all. This module currently supports CDP and LLDP, but not CTRON-CDP. These methods will query both CDP and LLDP and return the combination of all information. As a result, there may be identical topology information returned from the two protocols causing duplicate entries. It is the calling program's responsibility to identify any duplicate entries and de-duplicate if necessary.

$enterasys->hasCDP()

Returns true if the device is running either CDP or LLDP.

$enterasys->c_if()

Returns reference to hash. Key: iid Value: local device port (interfaces)

$enterasys->c_ip()

Returns reference to hash. Key: iid Value: remote IPv4 address

If multiple entries exist with the same local port, c_if(), with the same IPv4 address, c_ip(), it may be a duplicate entry.

If multiple entries exist with the same local port, c_if(), with different IPv4 addresses, c_ip(), there is either a non-CDP/LLDP device in between two or more devices or multiple devices which are not directly connected.

Use the data from the Layer2 Topology Table below to dig deeper.

$enterasys->c_port()

Returns reference to hash. Key: iid Value: remote port (interfaces)

$enterasys->c_id()

Returns reference to hash. Key: iid Value: string value used to identify the chassis component associated with the remote system.

$enterasys->c_platform()

Returns reference to hash. Key: iid Value: Remote Device Type
