The commands shown in this chapter apply to the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010. Where an entire command or certain attributes of a command have values specific to a particular switch, an exception is indicated by the following callouts:
To enable the functionality of generation and detection of the yellow alarm in the system, use the yellow interface configuration command. To disable the functionality, use the no form of this command.
yellow {generation | detection}Syntax Description
generation | If set, yellow alarm is generated in the event of frame loss. |
detection | If set, yellow alarm is detected in the event of the remote end experiencing frame loss and transmitting yellow. |
Both generation and detection are enabled.
Interface configuration
If the received signal has been lost the yellow alarm should be generated to indicate a frame loss event, thus ensuring that the alarm is sent to the remote end.
When the remote end is transmitting a yellow alarm indicating a frame loss event, the yellow alarm detection must be enabled to detect the alarm condition.
Disable the yellow alarm gereration and detection depending upon the circumstances. Enabling yellow detection would be useless if the remote end has yellow genration disabled.
The following example shows how to enable the generation and detection of yellow alarm.
Switch(config)# interface atm 0/1/0 Switch(config-if)# yellow generation Switch(config)# interface atm 0/1/0 Switch(config-if)# yellow detection
The following examples shows how to disable the generation and detection of yellow alarm
Switch(config)# interface atm 0/1/0 Switch(config-if)# no yellow generation Switch(config)# interface atm 0/1/0 Switch(config-if)# no yellow detection
