ANCP Monitoring and Management
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
Verifying and Monitoring ANCP Neighbors
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:
user@host> show ancp neighbor detail
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
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:
user@host> show ancp neighbor
user@host> show ancp neighbor 203.0.113.64
user@host> show ancp neighbor 00:00:5E:00:53:ba
Verifying and Monitoring ANCP Subscribers
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
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
