=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from an

Enterasys device through SNMP.

=head1 TABLE METHODS
|
|
|
|
These are methods that return tables of information in the form of a reference
|
|
to a hash.
|
|
|
|
=head2 Overrides
|
|
|
|
=over
|
|
|
|
=item $enterasys->interfaces()
|
|
|
|
Mapping between the Interface Table Index (iid) and the physical port name.
|
|
|
|
=item $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()
|
|
|
|
=item $enterasys->i_duplex()
|
|
|
|
See documentation for mau_i_duplex() in L<SNMP::Info::MAU/"TABLE METHODS">.
|
|
|
|
=item $enterasys->i_duplex_admin()
|
|
|
|

|
|
L<SNMP::Info::MAU/"TABLE METHODS">.

|
|
|
|
=head2 Time Filter Table Index Overrides
|
|
|
|
The time filter C<TimeFilter> implementation continuously increments when
|
|
walked and we may never reach the end of the table. This behavior can be
|
|
modified with the C<"set snmp timefilter break disable"> command,
|
|
unfortunately it is not the default. These methods are overridden to
|
|
supply a partial value of zero which means no time filter.
