no path pathChannel { ds1 | e1 } tributaryIdentifier bert
Release Information
Command introduced before JUNOSe Release
7.1.0.
Description
Enables bit error rate tests using the specified
pattern at the DS1/E1 over SONET/SDH VT layer on channelized SONET
and SDH interfaces. The no version stops
the test that is running.
Options
pathChannel—Number, in the
range 1–2147483648, that identifies the path
tributaryIdentifier—Specifier
for the tributary in the format pathChannel { ds1 | e1 } pathPayload/tributaryGroup/tributaryNumber
pathPayload—Payload number
for the path; value is 1 for SONET and in the range 1–3 for
SDH
tributaryGroup—Number, in
the range 1–7, that identifies the group within the path
tributaryNumber—Number of
the tributary within the tributary group; the value is in the range
1–4 if the tributary type is vt15 or tu11 and in the range 1–3
if the tributary type is tu12
pattern—One of the following
test patterns:
2^11—Pseudorandom test pattern, 2,047 bits long
2^15—Pseudorandom test pattern, 32,767 bits long
2^20-O153—Pseudorandom test pattern, 1,048,575 bits
long
time—Duration of the test,
in the range 1–1440 minutes
unframed—Test bit pattern occupies all bits on the
link, overwriting the framing bits. If you do not specify this keyword,
the test bit pattern occupies only T1/E1 payload bits.
