Configuring Triggers for CRC Errors
To enable and configure the keepalives, perform the following procedure, beginning in global
configuration mode:
Configuring Triggers for CRC Errors
You can configure a span shutdown when the ML-Series card receives CRC errors at a rate that exceeds
the configured threshold and configured soak time.
Command Purpose
Step 1 Router(config)# interface rpr-ieee 0 Activates interface configuration mode to
configure the RPR-IEEE interface.
Step 2 Router(config-if)# rpr-ieee keepalive-timer
milliseconds [east | west]
Specifies the amount of time that can pass before
a keepalive event is triggered after not receiving a
fairness message from a neighboring station.
Values range from 2 to 200 milliseconds. The
default is 3 milliseconds.
(Optional) You can also specify the east or west
ringlet.
Step 3 Router(config)# no shut Enables the RPR-IEEE interface and changes the
mode from the default passthrough.
Step 4 Router(config)# end Returns to privileged EXEC mode.
Step 5 Router# copy running-config startup-config (Optional) Saves configuration changes to the
TCC2/TCC2P flash database.
