=head1 MODE
=over 8
=item B<--interface>
Set the interface (number expected) ex: 1,2,... (empty means 'check all interface').
=item B<--name>
Allows to use interface name with option --interface instead of interface oid index (Can be a regexp)
=item B<--speed>
Set interface speed (in Mb).
=item B<--skip-speed0>
Don't display interface with speed 0.
=item B<--filter-status>
Display interfaces matching the filter (example: 'up').
=item B<--use-adminstatus>
Display interfaces with AdminStatus 'up'.
=item B<--oid-filter>
Choose OID used to filter interface (default: ifName) (values: ifDesc, ifAlias, ifName).
=item B<--oid-display>
Choose OID used to display interface (default: ifName) (values: ifDesc, ifAlias, ifName).
=item B<--display-transform-src>
Regexp src to transform display value. (security risk!!!)
=item B<--display-transform-dst>
Regexp dst to transform display value. (security risk!!!)
=item B<--add-extra-oid>
Display an OID.
Example: --add-extra-oid='alias,.1.3.6.1.2.1.31.1.1.1.18'
or --add-extra-oid='vlan,.1.3.6.1.2.1.31.19,%{instance}\..*'
=item B<--add-mac-address>
Display interface mac address.
