Triggering ANCP OAM
You can trigger ANCP OAM to perform a loopback test on the local loop between the access node and the CPE to help isolate simple faults. On an ATM-based local loop, the ANCP operation triggers the access node to generate ATM (F4/F5) loopback cells on the local loop. On an Ethernet-based local loop, the ANCP operation triggers the access node to generate an Ethernet loopback message on the local loop. When the test completes, the access node sends a message to the router with the results.
Issue the request ancp oam neighbor command from CLI operational mode to initiate testing of a local loop identified by the IP address or system name of the ANCP neighbor and the ACI for a subscriber on that access node.
Issue the request ancp oam interface command from CLI operational mode to initiate testing of a local loop identified by the ANCP interface or interface set associated with a subscriber and the ACI for a subscriber on that access node.
With both commands, you can also specify how many times the test must be run and how long the router waits for a response to the OAM request.
To initiate ANCP local loop testing:
- Identify the loop by the subscriber identifier and the
neighbor’s IP address; optionally specify how many times the
test runs and the timeout period.user@host> request ancp oam neighbor ip-address 192.168.32.5 subscriber “dslam port-2-10” count 5 timeout 600
- Identify the loop by the subscriber identifier and the
neighbor’s system name; optionally specify how many times the
test runs and the timeout period.user@host> request ancp oam neighbor system-name ba:ad:be:ef:10:10 subscriber “dslam port-2-10” count 10 timeout 600
- Identify the loop by the subscriber identifier and the
interface associated with the subscriber; optionally specify how many
times the test runs and the timeout period.user@host> request ancp oam interface ge-1/0/2.12 identifier-string timeout 15
- Identify the loop by the subscriber identifier and the
set of interfaces associated with the subscriber; optionally specify
how many times the test runs and the timeout period.user@host> request ancp oam interface interface-set vlan5 identifier-string count 3
