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.
Monitoring Interfaces
To display statistics for channelized SONET and SDH interfaces, use the
show controllers
sonet
command. The following section describes some of the options for the command
and shows some sample displays.
From User Exec mode, use the following
show
commands to monitor and display the
T3, T1/E1, and HDLC serial data channel information:
•
Display E1 or T1 statistics for E1 or T1 over a VT.
host1#
show controllers sonet 2/0 e1
•
Display T3 statistics.
host1#
show controllers sonet 2/1 ds3
•
Display statistics for the section, line, path, and tributary layers.
host1#
show controllers sonet 2/1 section
•
Display the configuration for channelized SONET and SDH interfaces.
host1#
show controllers sonet 2/0 configuration
•
Display statistics for serial interfaces.
host1#
show interfaces serial 2/0:1/1/1/1/1
