Parameters
service-instance instance-id
: Specifies a service instance by its ID in the range of 1 to
32767.
mep mep-id
: Specifies the source MEP by its ID in the range of 1 to 8191.
target-mac mac-address : Specifies the target MEP by its MAC address, which is in the format
of H-H-H.
target-mep target-mep-id
: Specifies the target MEP by its ID in the range of 1 to 8191.
number number : Specifies the number of sent TST frames. The value range for the number
argument is 1 to 10, and the default is 5.
length-of-test length : Specifies the length of the Test TLV (Type/Length/Value) in the TST
frame. The value range for the length argument is 4 to 1400, in bytes. The default value is 64.
pattern-of-test { all-zero | prbs } [ with-crc ]
: Specifies the pattern of the Test TLV
in the TST frame:
•
all-zero
(all-zero value without CRC-32), which is the default pattern.
•
prbs
(pseudo random bit sequence without CRC-32).
•
all-zero with-crc
(all-zero value with CRC-32).
•
prbs with-crc
(pseudo random bit sequence with CRC-32).
Usage guidelines
The TST function detects bit errors between the source and target MEPs by using TST frames.
To view the TST test result, use the
display cfd tst
command on the target MEP.
Examples
# Enable the TST function to test the bit errors between source MEP 1101 and target MEP 1003 in
service instance 1.
<Sysname> cfd tst service-instance 1 mep 1101 target-mep 1003
5 TSTs have been sent. Please check the result on the remote device.
