path ds1|e1 bert
Syntax
path pathChannel { ds1 | e1 } tributaryIdentifier bert
pattern pattern interval time [ unframed
]
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.
