-sv <mop_version> Specifies which MOP version protocol to use. If 3, then MOP V3
(DECNET Phase IV) packet format is used. If 4, then MOP V4
(DECNET Phase V IEEE 802.3) format is used.
-to <loop_time> Specifies the time in seconds allowed for the loop messages to be
returned. The default is 2 seconds.
-w <wait_time> Specifies the time in seconds to wait between passes of the test.
The default is 0 (no delay). The network device can be very CPU
intensive. This option will allow other processes to run.
Environment Variables
e*a*_loop_count Specifies the number (hex) of loop requests to send. The default is
0x3E8 loop packets.
e*a*_loop_inc Specifies the number (hex) of bytes the message size is increased
on successive messages. The default is 0xA bytes.
e*a*_loop_patt Specifies the data pattern (hex) for the loop messages. The
following are legitimate values.
0 : all zeros
1 : all ones
2 : all fives
3 : all 0xAs
4 : incrementing data
5 : decrementing data
ffffffff : all patterns
loop_size Specifies the size (hex) of the loop message. The default packet
size is 0x2E.
