Triggering ANCP OAM to Test the Local Loop

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 00:00:5E:00:53:ba 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
```

Purpose

View ANCP neighbor information:

Action

To display summary information about all ANCP neighbors:
```
user@host> show ancp neighbor
```
To display information about a specific ANCP neighbor, add the IP address or MAC address to the command:
```
user@host> show ancp neighbor ip-address 203.0.113.64
user@host> show ancp neighbor system-name 00:00:5E:00:53:ba
```

To display detailed information, add detail to the command:

content_copy zoom_out_map
user@host> show ancp neighbor detail

content_copy zoom_out_map
user@host> show ancp neighbor system-name 00:00:5E:00:53:ba detail

To display a count of ANCP neighbors in various states and the total number of neighbors, or a count of DSL lines in various states for all subscribers for a particular neighbor:
```
user@host> show ancp summary neighbor
user@host> show ancp summary neighbor 203.0.113.64
```
To display total and state-wise counts of both ANCP neighbors and subscribers:
```
user@host> show ancp summary
```

Clearing ANCP Neighbors

Purpose
Action

Purpose

Clear ANCP neighbor information.

Action

To clear connections with all ANCP neighbors:
```
user@host> clear ancp neighbor
```
To clear the connection with a specific ANCP neighbor, add the IP address or MAC address to the command:
```
user@host> clear ancp neighbor ip-address 203.0.113.64
```
```
user@host> clear ancp neighbor system-name 00:00:5E:00:53:ba
```

To verify that the connection has been cleared:

content_copy zoom_out_map
user@host> show ancp neighbor 

content_copy zoom_out_map
user@host> show ancp neighbor 203.0.113.64

content_copy zoom_out_map
user@host> show ancp neighbor 00:00:5E:00:53:ba

Verifying and Monitoring ANCP Subscribers

Purpose
Action

Purpose

View ANCP subscriber (local access loop) information:

Action

To display summary information about all ANCP subscribers:
```
user@host> show ancp subscriber
```
To display information about all ANCP subscribers connected through a particular ANCP neighbor:
```
user@host> show ancp subscriber neighbor 203.0.113.64
```
To display information about an ANCP subscriber specified by the ACI:
```
user@host> show ancp subscriber “port-2-11”
```
To display detailed information, add detail to the command:
```
user@host> show ancp subscriber detail
```
```
user@host> show ancp subscriber neighbor 203.0.113.64 detail
```
To display a count of subscribers in various states and the total number of subscribers:
```
user@host> show ancp summary subscriber
```
To display total and state-wise counts of both ANCP neighbors and subscribers:
```
user@host> show ancp summary
```

Clearing ANCP Subscribers

Purpose
Action

Purpose

Clear ANCP subscriber information.

Action

To clear connections with all ANCP subscribers that are not mapped:
```
user@host> clear ancp subscriber
```
To clear connections with all ANCP subscribers that are mapped:
```
user@host> clear ancp neighbor
```
To clear the connection with an ANCP subscriber identified by a particular ACI on all neighbors, add the identifier to the command:
```
user@host> clear ancp subscriber identifier port-2-10
```
To clear the connection with an ANCP subscriber identified by a particular ACI on a specific neighbor, add the identifier and either the IP address or MAC address to the command:
```
user@host> clear ancp subscriber identifier port-2-10 ip-address 203.0.113.64
```
```
user@host> clear ancp subscriber identifier port-2-10 system-name 00:00:5E:00:53:ba
```
To verify that the connection has been cleared:
```
user@host> show ancp subscriber 
```

Clearing and Verifying ANCP Statistics

Purpose
Action

Purpose

Clear ANCP statistics.

Action

To clear all ANCP statistics:
```
user@host> clear ancp statistics
```
To clear statistics for a specific ANCP neighbor, add the IP address or MAC address to the command:
```
user@host> clear ancp statistics ip-address 203.0.113.64
```
```
user@host> clear ancp statistics system-name 00:00:5E:00:53:ba
```
To verify that the statistics have been cleared:
```
user@host> show ancp statistics 
```
