Configuring Line and Section Overhead
To configure line and section overhead:
enable
configure terminal
controller sdh 0/0/16
overhead s1s0 2
overhead j0 expected length 16-byte
overhead j0 expected tracebuffer rx Message
overhead j0 tx length 1-byte
overhead j0 tx tracebuffer tx Message
end
To restore the system to its default condition, use the no form of the overhead j0 command.
Note
Threshold
Set the path BER threshold values.
• b1-tca — Enables Bit Error Rate (BER) threshold crossing alerts for B1.
• b2-tca — Enables BER threshold crossing alerts for B2.
• sd-ber — Enables the threshold of the Signal Degrade (SD) BER that is used to trigger a signal degrade
• sf-ber — Configures the threshold of the Signal Failure (SF) BER that is used to trigger a link state
Configuring Line and Section Threshold
To configure line and section threshold:
enable
configure terminal
mode sdh
controller sdh 0/0/16
threshold b1-tca 5
threshold b2-tca 5
threshold sd-ber 5
threshold sf-ber 5
end
To restore the system to its default condition, use the no form of the threshold command.
Note
Loopback
Sets a loopback to test the SDH port.
• local — Loops the signal from Tx to Rx path. Sends alarm indication signal (AIS) to network.
