Testing Connectivity
Use the path overhead j1 command to check for connectivity between the router
and a SONET/SDH device at the other end of the line. This command
defines:
- A message that the router sends from the specified interface
to the SONET/SDH device at the other end of the line.
- A message that the router expects to receive on the specified
interface from the SONET/SDH device at the other end of the line.
When you define a message that the interface sends,
you must monitor receipt of that message at the remote end.
When you define a message that the interface expects
to receive, you should configure the remote device to transmit the
same message to the interface. You can then use the show
controllers sonet command to compare the expected and
received messages.
path overhead j1
- Use to define messages that the router sends to or expects
to receive from a SONET/SDH device connected to a cOCx/STMx interface.
- Specify a path identifier between 1 and 2,147,483,648
for a cOCx/STMx interface.
- Specify the keyword msg for
a message that the router transmits for this path.
- Specify the keyword exp-msg to define a message that the router expects to receive on this path.
- Define a message of up to 62 characters for SONET or up
to 15 characters for SDH.
- Configure the remote device to send the same message that
the router expects to receive on this path. You can then compare the
expected and received messages in the display of the show controllers sonet command.
- Example for cOCx/STMx interface:
- host1(config-controller)#path 2 overhead j1
exp-msg goodbye
- Use the no version to restore
the default situation, in which all the characters in the transmitted
or expected message are zeros.
- See path overhead j1.
