Performance Monitoring and Overhead Bytes
The VCoP smart SFP supports the performance monitoring counter to maintain the path quality of the link.
You can view the statistics or error count generated on the VCoP smart SFP, if you have the configuration that is described:
enable
configure terminal
controller SONET 0/0/8
threshold b1-tca 8
threshold b2-tca 8
framing sonet
overhead j0 6
overhead s1s0 2
!
sts-1 1
overhead c2 2
threshold b3-ber_sd 8
threshold b3-ber_sf 8
overhead 1 message PATH_TRACEj
threshold b3-tca 8
mode unframed
cem-group0 cep
!
The following parameters affect SONET configuration:
•
Overhead - Sets the SONET overhead bytes in the frame header to a specific standards requirement, or to ensure interoperability
with equipment from another vendors.
◦
J0 - Sets the J0/C1 byte value in the SONET section overhead.
1 byte, 16 bytes, and 64 bytes are the supported values for J0.Note
◦
J1 - Path Trace Byte
◦
C2- Path Signal label
◦
S1S0 - Sets the SS bits value of the H1 byte in the SONET line overhead
•
Alarm Reporting - Enables reporting for all or selected alarms.
◦
B1 - Section BIP Error (SF/SD)
◦
B2 - Line BIP Error (SF/SD)
◦
B3 (SF/SD) - STS Path BIP Error
◦
sd-ber - Sets Signal Degrade BER threshold
◦
sf-ber - Sets Signal failure BER threshold
The performance monitoring result is displayed using the show controller command. The following snippets are the performance
monitoring details when the show controller command is executed.
Router# show controller sonet 0/0/8
SONET 0/0/8 is up.
Hardware is 12xGE-4x10GE-FIXED
