DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide Usage Guideline This command is used to delete the stored link-trace response data that has been initiated by the specified MEP. Example This example shows how to delete received link-trace responses. Switch# clear cfm linktrace mepid 1 ma name op-ma1 domain op-domain1 Switch# 15-24 ais This command is used to enable and configure the parameters of the Alarm Indication Signal (AIS) function. Use the no form of this command to disable the AIS function. ais [period PERIOD] [level LEVEL] no ais [period | level] Parameters period PERIOD level LEVEL (Optional) Specifies the transmitting interval of the AIS PDU. It can be either 1second or 1 minute. (Optional)Specifies the client MD level to which the MEP sends the AIS PDU. The range is from 0 to 7. Default By default, this option is disabled. The default period is 1 second. Command Mode CFM MEP Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is used to enable and configure the parameters of the AIS function on a MEP. If no optional parameter is specified, it will enable the AIS function. If the client level is not designated, it will equal the MD level that the most immediate client layer MIPs and MEPs exist on. This default client maintenance domain level is not a fixed value. It may change when creating or deleting a higher level maintenance domain and MA on the device. Upon detecting a defect condition the MEP can immediately start transmitting periodic frames with ETH-AIS information at the client level. A MEP continues to transmit periodic frames with ETH-AIS information until the defect condition is removed. Upon receiving a frame with ETH-AIS information from its server (sub) layer, a client (sub) layer MEP detects AIS condition and suppresses alarms associated with all peer MEPs. A MEP resumes alarm generation upon detecting defect conditions once AIS condition is cleared When the most immediate client layer MIPs and MEPs do not exist, the client MD level cannot be calculated. If the client MD level cannot be calculated and the user does not designate a client level, the AIS PDU cannot be transmitted. 190
