Configuring The Atm Clock; Configuring Cable Length; Controlling Atm Alarm Reporting - Cisco 10000 Series Configuration Manual

Chapter 2 8-Port E3/DS3 ATM Line Card Configuration

Configuring the ATM Clock

Use the atm clock internal command to configure the clock source as internal.
atm clock {internal | line}
no atm clock internal
The default clock setting is no atm clock internal, which means that clocking is derived from the line.
In the following example, clocking is set to internal.
Router(config)# interface atm 5/0/0
Router(config-if)# atm clock internal

Configuring Cable Length

The atm lbo command improves signal strength for losses associated with lengthy cables. To specify
whether the cable attached to the interface is short or long, use the atm lbo command in the following
format:
atm lbo {short | long}
Where:
short is for a cable that is less than 225 feet.
long is for a cable that is 225 feet or greater.
The default is short.
In the following example, the cable length is set to short:
Router(config)# interface 2/0/0
Router(config-controller)# atm lbo short

Controlling ATM Alarm Reporting

To control alarms so that they are logged to the console for an ATM interface, use the atm report
command in interface configuration mode.
atm report {los | oof | ais | ferf | lcd}
no atm report {los | oof | ais | ferf | lcd}
Where:
•
•
•
•
•
To disable logging of alarms, use the no form of this command.
Reporting an alarm means that the alarm can be logged to the console. Not all alarms are logged. The
alarm hierarchy rules dictate that only the most severe alarm of an alarm group is reported. Whether an
alarm is reported or not, you can view the current state of a defect by checking the Active Defects line
from the show controllers atm command output.
