AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly to SNMP::Session
DestHost => 'myswitch',
Community => 'public',
Version => 2
)

=head1 GLOBALS
These are methods that return scalar values from SNMP
=over
=item $arista->vendor()
Returns 'Arista Networks, Inc.'
=item $arista->model()
Tries to reference $arista->id() to one of the product MIBs listed above
Removes 'arista' from the name for readability.
=item $arista->os()
Returns 'EOS'
=item $arista->os_ver()
Grabs the os version from C<sysDescr>

=item $arista->lldp_if()
Returns the mapping to the SNMP Interface Table.
=item C<agg_ports>
Returns a HASH reference mapping from slave to master port for each member of
a port bundle on the device. Keys are ifIndex of the slave ports, Values are
ifIndex of the corresponding master ports.
