path ds1|e1 loopback
Syntax
path pathChannel { ds1 | e1 } tributaryIdentifier loopback
{ local | network { line | payload } }
no path pathChannel { ds1 | e1 } tributaryIdentifier loopback
path pathChannel ds1 tributaryIdentifier loopback remote
{ line fdl { ansi | bellcore } | payload [ fdl ] [ ansi ] }
no path pathChannel { ds1 | e1 } tributaryIdentifier loopback remote
Release Information
Command introduced before JUNOSe Release 7.1.0.
Description
Configures a loopback at the DS1/E1 over SONET/SDH VT layer on channelized
SONET and SDH interfaces. The
no version turns off the loopback.
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
■
local—Loops the router output data back toward the router at the T1/E1 framer;
on supported line modules also sends an alarm indication signal (AIS) out toward
the network.
■
network { line | payload }—Specify the line keyword to loop the data back
toward the network before the T1/E1 framer and automatically set a local
loopback at the HDLC controllers. Specify the
payload keyword to loop the
payload data back toward the network at the T1/E1 framer and automatically
set a local loopback at the HDLC controllers.
■
remote line fdl ansi (T1 line only)—Sends a repeating 16-bit ESF data link code
word (00001110 11111111) to the remote end requesting that it enter into a
network line loopback. Specify the
ansi keyword to enable the remote line FDL
ANSI bit loopback on the T1 channel, according to the ANSI T1.403 specification.
■
remote line fdl bellcore (T1 line only)—Sends a repeating 16-bit ESF data link
code word (00010010 11111111) to the remote end requesting that it enter into
a network line loopback. Specify the
bellcore keyword to enable the remote line
