Use to define messages that the router sends to or expects to receive from a
SONET/SDH device connected to one of its SONET interfaces.
Do not specify a path identifier for unchannelized SONET interfaces.
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 unchannelized SONET interfaces:
host1(config-controller)#path overhead j1 msg hello
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.
You can monitor interface statistics and APS/MSP settings.
NOTE: The E120 and E320 routers output for monitor and show commands
is identical to output from other E Series routers, except that the E120 and
E320 routers output also includes information about the adapter identifier
in the interface specifier (slot/adapter/port).
You can set statistics baselines for the section, line, and path layers using the baseline
interface sonet commands.
To display statistics for SONET and SDH interfaces, use the show controllers sonet
commands. Use the delta options to display statistics with the baseline subtracted.
Use to set a statistics baseline for the SONET/SDH line layer.
The router implements the baseline by reading and storing the MIB statistics at the
time the baseline is set and then subtracting this baseline whenever baseline-relative
statistics are retrieved.
