Output Fields
Table 1 lists the output fields for the show ancp neighbor command. Output fields are listed in the approximate order in which they appear.
Table 1: show ancp neighbor Output Fields
Field Name | Field Description | Level of Output |
|---|---|---|
IP Address | IP address of the ANCP neighbor. | brief detail none |
System Name | MAC address of the ANCP neighbor. | detail |
State | State of the ANCP adjacency:
| All levels |
Up Time | How long the adjacency has been up in one of the following formats:
| brief detail none |
Subscriber Count | Number of subscribers associated with the ANCP neighbor (access local loop). | brief none |
Capabilities | Negotiated ANCP capability:
| Al levels |
TCP Port | TCP port on which ANCP messages are exchanged. | detail |
System Instance | Number identifying the ANCP link instance from the edge device’s perspective. | detail |
Peer Instance | Number identifying the ANCP instance from the access node’s perspective. This number is unique and changes when the node or link comes back up after going down. | detail |
Timer | Adjacency timer value advertised by the ANCP peer in 100 ms increments; the interval between ANCP ACK messages. This value remains constant for the duration of an ANCP session. | detail |
Partition Type | Number that identifies whether partitions are used and how the ID is negotiated:
| detail |
Partition Flag | Number that specifies the type of partition requested: 1 (new adjacency) or 2 (recovered adjacency). | detail |
Partition Identifier | Number that associates the ANCP message with a specific partition. | detail |
Dead Timer | Remaining period that the edge device waits for adjacency packets from a neighbor before declaring the neighbor to be down. The maximum dead time value is three times the configured adjacency timer value. This field displays the current value based on the time that the last adjacency packet was received. | detail |
Received | Count of the following ANCP message packets received by the node from the neighbor:
| detail |
Sent | Count of the following ANCP message packets sent by the node:
| detail |
Max Discovery Limit Exceed Count | Number of times that the maximum number of discovery table entries accepted from the neighbor has been exceeded. | detail |
