Testing Interfaces
Specify the duration of the test in the range 1–1440 minutes.
Optionally, specify the unframed keyword to overwrite the framing bits.
Example
host1(config-controll)#path 12 ds1 1/3/4 bert pattern 2^11 interval 10
unframed
Use the no version to stop the test that is running.
See path ds1|e1 bert.
Use to enable bit error rate tests using the specified pattern at the T3 layer.
Unlike other configuration commands, "path ds3 bert" on page 146 is not stored
in NVRAM.
Specify one of the following options:
0s Repetitive test pattern of all zeros, 00000...
1s Repetitive test pattern of all ones, 11111...
2^9 Pseudorandom test pattern, 511 bits in length
2^11 Pseudorandom test pattern, 2047 bits in length
2^15 Pseudorandom test pattern, 32,767 bits in length
2^20 Pseudorandom test pattern, 1,048,575 bits in length
2^20-QRSS Pseudorandom QRSS test pattern, 1,048,575 bits in length
2^23 Pseudorandom test pattern, 8,388,607 bits in length
alt-0-1 Repetitive alternating test pattern of zeros and ones, 01010101...
Specify the duration of the test in the range 1–1440 minutes.
Example
host1(config-controll)#path 12 ds3 2 bert pattern Os interval 10
Use the no version to stop the test that is running.
See path ds3 bert.
Use to enable bit error rate tests using the specified pattern at the T1 over T3
layer.
Unlike other configuration commands, "path ds3 t1 bert" on page 146 is not
stored in NVRAM.
Specify one of the following options:
2^11 Pseudorandom test pattern, 2047 bits in length
