Check Defect Detection
The CFM service allows different types of defects to be detected in the network through the processing of CFM datagrams received on a network interface. The following scenarios show how, with different configurations, these defects are detected, and how to configure the service to avoid detecting certain defects.
Detect XconCCM Defect Due To Low Level
Description
In this scenario, a CFM service with domain level 6 is configured in DUT0. However, in DUT1 a CFM service with domain level 5 is configured. This causes CFM datagrams to be received in DUT0 with a domain level lower than its own and, consequently, XconCCM type defects are detected.
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.0.0.1/24
Step 2: Set the following configuration in DUT1:
set interfaces ethernet eth0 address 10.0.0.2/24
Step 3: Set the following configuration in DUT0:
set system alarm TEST_ALARM initial-state true set service cfm domain TEST_DOMAIN level 6 set service cfm domain TEST_DOMAIN service TEST_SERVICE alarm delay 2500 set service cfm domain TEST_DOMAIN service TEST_SERVICE alarm reset 2500 set service cfm domain TEST_DOMAIN service TEST_SERVICE sender-id chassis set service cfm domain TEST_DOMAIN service TEST_SERVICE continuity-check interval 1s set service cfm domain TEST_DOMAIN service TEST_SERVICE mep 10 interface eth0 set service cfm domain TEST_DOMAIN service TEST_SERVICE mep 10 alarm TEST_ALARM set service cfm domain TEST_DOMAIN service TEST_SERVICE mep 10 rmep 20
Step 4: Set the following configuration in DUT1:
set system alarm TEST_ALARM initial-state true set service cfm domain TEST_DOMAIN level 5 set service cfm domain TEST_DOMAIN service TEST_SERVICE alarm delay 2500 set service cfm domain TEST_DOMAIN service TEST_SERVICE alarm reset 2500 set service cfm domain TEST_DOMAIN service TEST_SERVICE sender-id chassis set service cfm domain TEST_DOMAIN service TEST_SERVICE continuity-check interval 1s set service cfm domain TEST_DOMAIN service TEST_SERVICE mep 20 interface eth0 set service cfm domain TEST_DOMAIN service TEST_SERVICE mep 20 alarm TEST_ALARM set service cfm domain TEST_DOMAIN service TEST_SERVICE mep 20 rmep 10
Note
After a few seconds, the CFM service of DUT0 should detect a DefXconCCM defect.
Step 5: Run command service cfm mep show at DUT0 and check if output matches the following regular expressions:
RDI bit: up FNG state: defect reported FNG current defect: DefXconCCM FNG last reported defect: DefXconCCM \s+20\s+failed\s+0\s+down\s+not available\s+not availableShow output

Note
After reconfiguring the CFM service with domain level 6 in DUT1, DUT0 will no longer receive CFM datagrams with a domain level lower than its own and, consequently, XconCCM type defects will no longer be detected.
Step 7: Set the following configuration in DUT1:
set service cfm domain TEST_DOMAIN level 6
Note
After a few seconds, the CFM service of DUT0 should not detect any defects.
Step 8: Run command service cfm mep show at DUT0 and check if output matches the following regular expressions:

Detect XconCCM Defect Due To Wrong MAID
Description
In this scenario, a CFM service with Maintenance Association (MA) TEST_SERVICE is configured in DUT0. However, in DUT1 a CFM service with MA OTHER_TEST_SERVICE is configured. This causes CFM datagrams to be received in DUT0 with a wrong Maintenance Association Identifier (MAID) and, consequently, XconCCM type defects are detected.
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.0.0.1/24
Step 2: Set the following configuration in DUT1:
set interfaces ethernet eth0 address 10.0.0.2/24

Avoid Detect ErrorCCM Defect
Description
In this scenario, a CFM service with remote MepID 20 is configured in DUT0. In DUT1, a CFM service with MepID 30 is configured. This causes CFM datagrams to be received in DUT0 with an unknown remote MepID. Consequently, ErrorCCM defects are detected. However, the CFM service can be configured so that it doesn’t detect defects under a certain priority level. Since the ErrorCCM defect has a priority of 4, by configuring a minimum detection level of 5 in DUT0, ErrorCCM defects are not detected.

Avoid Detect RemoteCCM Defect
Description
In this scenario, a CFM service with remote MepID 20 is configured in DUT0. But, in DUT1, the CFM service is not configured. This causes CFM datagrams of the expected remote MepID to not be received in DUT0 and, consequently, RemoteCCM errors are detected. However, the CFM service can be configured so that it doesn’t detect defects under a certain priority level. Since the RemoteCCM defect has a priority of 3, by configuring a minimum detection level of 4 in DUT0, RemoteCCM errors are not detected.
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.0.0.1/24
Step 2: Set the following configuration in DUT1:

Avoid Detect RDICCM Defect
Description
In this scenario, a CFM service with MepID 10 is configured in DUT0. But, in DUT1, a CFM service with no remote MepID is configured. This causes DUT1 to detect a defect and activate its RDI flag, which also causes DUT0 to receive CFM datagrams with the RDI flag in UP. Consequently, RDICCM defects are detected. However, the CFM service can be configured so that it doesn’t detect defects under a certain priority level. Since the RDICCM defect has a priority of 1, by configuring a minimum detection level of 2 in DUT0, RDICCM defects are not detected.
Scenario
Step 1: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.0.0.1/24
Step 2: Set the following configuration in DUT1:
