Configuring the Attribute Discovery Timer
Because station attributes are communicated separately from topology and protection packets, there is a
separate timer to control the frequency at which these packets are sent. Attribute propagation is therefore
determined by the attribute discovery (ATD) timer. The default rate is one packet per second for each
ringlet.
Note Configure both ringlets with the same value.
To enable and configure the ATD, perform the following procedure, beginning in global configuration
mode:
Configuring the Reporting of SONET Alarms
The ML-Series card reports SONET/SDH alarms through the CTC alarm panel in the same manner as
other ONS cards. The ML-Series card can also report SONET/SDH alarms through the Cisco IOS
command-line interface (CLI). Configuring CTC reporting does not affect Cisco IOS CLI reporting or
vice-versa.
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 atd-timer
seconds
Specifies the time, in seconds, within which one
station attributes packet is sent for each ringlet.
The default is one packet for each ringlet per
second.
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.
