=head1 TABLE METHODS
|
|
|
|
These are methods that return tables of information in the form of a reference
|
|
to a hash.
|
|
|
|
=over
|
|
|
|
=item $juniper->qb_fdb_index()
|
|
|
|
Returns reference to hash: key = FDB ID, value = VLAN ID.
|
|
|
|
=item $juniper->v_index()
|
|
|
|
Returns (C<jnxL2aldVlanTag>) or (C<jnxExVlanTag>) depending upon switch
|
|
software version
|
|
|
|
=item $juniper->v_name()
|
|
|
|
Returns (C<jnxL2aldVlanName>) or (C<jnxExVlanName>) depending upon switch
|
|
software version
|
|
|
|
=item $juniper->v_type()
|
|
|
|
Returns (C<jnxL2aldVlanType>) or (C<jnxExVlanType>) depending upon switch
|
|
software version
|
|
|
|
=item $juniper->i_trunk()
|
|
|
|
(C<jnxExVlanPortAccessMode>)
|
|
|
|
=item $juniper->i_vlan()
|
|
|
|
Returns a mapping between C<ifIndex> and the PVID or default VLAN.
|
|
|
|
=item $juniper->i_vlan_membership()
|
|
|
|
Returns reference to hash of arrays: key = C<ifIndex>, value = array of VLAN
|
|
IDs. These are the VLANs which are members of the egress list for the port.
|
|
|
|
=item $juniper->i_vlan_membership_untagged()
|
|
|
|
Returns reference to hash of arrays: key = C<ifIndex>, value = array of VLAN
|
|
IDs. These are the VLANs which are members of the untagged egress list for
|
|
the port.
|
|
|
|
=item $juniper->peth_port_ifindex()
|
|
|
|
Returns reference to a hash: key= PowerEthernet MIB interface number,
|
|
value = C<ifIndex>. As Juniper does not provide a mapping function,
|
|
this does it manually.
|
|
For example, ge-0/0/1 registers as PowerEthernet interface '1.2'
|
|

|
|
|
|
=head2 Pseudo F<ENTITY-MIB> information
|
|
|
|
These methods emulate F<ENTITY-MIB> Physical Table methods using
|
|
F<JUNIPER-MIB> and F<JUNIPER-VIRTUALCHASSIS-MIB>.
|
|
|
|
=over
|
|
|
|
=item $juniper->e_index()
|
|

|
|
if required.
|
|
|
|
=item $juniper->e_class()
|

|
|
|
Returns reference to hash. Key: IID, Value: Serial number
|
|
|
|
=item $juniper->e_pos()
|
|
|
|
Returns reference to hash. Key: IID, Value: The relative position among all
|
|
entities sharing the same parent.
|
|
|
|
=item $juniper->e_type()
|
|
|
|
Returns reference to hash. Key: IID, Value: Type of component/sub-component
|
|
as defined in F<JUNIPER-CHASSIS-DEFINES-MIB>.
|
|
|
|
=item $juniper->e_parent()
|
|
|
|
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.
|
|
|
|
=item $entity->e_fru()
|
|
|
|
BOOLEAN. Is a Field Replaceable unit?
