to a hash.

|

=item $tasman->i_duplex_admin()
|
||
|
||
Returns reference to hash of iid to administrative duplex setting.
|
||
|
||
First checks for fixed gigabit ports which are always full duplex. Next checks
|
||
the port administrative speed (C<portAdminSpeed>) which if set to
|
||
autonegotiate then the duplex will also autonegotiate, otherwise it uses the
|
||
reported port duplex (C<portDuplex>).
|
||
|
||
=item $tasman->i_speed_admin()

Returns reference to hash of iid to administrative speed setting.

=head2 Pseudo F<ENTITY-MIB> information

entities sharing the same parent.

Returns reference to hash. Key: IID, Value: Type of component/sub-component.

|
||
|
||
Returns reference to hash. Key: IID, Value: The value of e_index() for the

entity which 'contains' this entity. A value of zero indicates this entity
|

is not contained in any other entity.
