SNMP::Info::Entity3pm

Snmp interface to data stored in entity-mib. rfc 2737

Usage

 # Let SNMP::Info determine the correct subclass for you.
 my $entity = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        )
    or die "Can't connect to DestHost.\n";
 my $class      = $entity->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

Overview

ENTITY-MIB is used by Layer 2 devices from Brocade, Cisco, HP, and more.

See RFC 2737 for full details.

Create or use a device subclass that inherit this class. Do not use directly.

For debugging purposes you can call this class directly as you would SNMP::Info

 my $entity = new SNMP::Info::Entity (...);

Inherited Classes

none.

Required MIBs

ENTITY-MIB

Globals

none.

Table methods

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

$entity->entity_derived_serial(): Tries to determine the device serial number from the ENTITY-MIB. Only considers serial numbers for entries without a parent, or if they are of type chassis. Looks at "entPhysicalSerialNum" and then "entPhysicalDescr" for serial number.

$entity->entity_derived_os_ver(): Tries to determine the device OS version from the ENTITY-MIB. Only considers serial numbers for entries without a parent, or if they are of type chassis. Looks at "entPhysicalSoftwareRev" for the version.

Entity Table

$entity->e_index()

Index

("entPhysicalIndex")

$entity->e_alias()

Human entered, not usually used.

("entPhysicalAlias")

$entity->e_class()

Stack, Module, Container, Port ...

("entPhysicalClass")

$entity->e_descr()

Human Friendly

("entPhysicalClass")

$entity->e_fwver(): ("entPhysicalFirmwareRev")

$entity->e_fru()

BOOLEAN. Is a Field Replaceable unit?

("entPhysicalFRU")

$entity->e_hwver(): ("entPhysicalHardwareRev")

$entity->e_id()

This is human entered and not normally used.

("entPhysicalAssetID")

$entity->e_map()

See MIB.

("entAliasMappingIdentifier")

$entity->e_model()

Model Name of Entity.

("entPhysicalModelName")

$entity->e_name()

More computer friendly name of entity. Parse me.

("entPhysicalName")

$entity->e_parent()

0 if root.

("entPhysicalContainedIn")

$entity->e_port(): Maps Entity Table entries to the Interface Table ("IfTable") using $entity->e_map()

$entity->e_pos()

The relative position among all entities sharing the same parent.

("entPhysicalParentRelPos")

$entity->e_serial(): ("entPhysicalSerialNum")

$entity->e_swver(): ("entPhysicalSoftwareRev")

$entity->e_type()

This is an OID, which gets munged into the object name if the right MIB is loaded.

("entPhysicalVendorType")

$entity->e_vendor()

Vendor of Module.

("entPhysicalMfgName")
