Monitoring ANCP Discovery Table Entries

Purpose

Display ANCP discovery table entries.

You can use the optional delta keyword to display baseline statistics.

Action

To display ANCP discovery table entries:

host1# show l2c discovery-table brief
Neighbor Access-Loop-Id Down/UpStream(kbps) State --------------- ------------------------------ ------------------- ----- ACCESSNODE_10   Accessnode_10 atm 2/2:0.0      8064/1184 UP ACCESSNODE_10   Accessnode_10 atm 2/32:0.0     8064/1184  UP ACCESSNODE_10   Accessnode_10 atm 2/33:0.0     8064/1184   DOWN ACCESSNODE_10   Accessnode_10 atm 2/34:0.0     8064/1184   DOWN

To display a topology discovery table for a particular end-user-id:

host1# 
show l2c discovery-table end-user-id "Accessnode_10 atm 2/3:0.0"Access-Loop-Id: Dslam_10 atm 2/3:0.0     UP
  Neighbor: ACCESSNODE_10
  Actual-Data-Rate-Upstream: 1152(kbps)
  Actual-Data-Rate-Downstream: 8064(kbps)
  Attainable-Data-Rate-Upstream: 1176(kbps)
  Attainable-Data-Rate-Downstream: 9376(kbps)
  Line-State: 1(SHOWTIME)
  Dsl-Type: 0(Invalid transmission type)
  Total Line Attributes: 6

To display a topology discovery table for a particular neighbor:

host1# show l2c discovery-table neighbor "Accessnode_10"
Access-Loop-Id: Dslam_10 atm 10/5:0.0 DOWN Neighbor: DSLAM_10 Line-State: 2(IDLE) Dsl-Type: 0(Invalid transmission type) Total Line Attributes: 2 Access-Loop-Id: Dslam_10 atm 10/6:0.0 DOWN Neighbor: DSLAM_10 Line-State: 2(IDLE) Dsl-Type: 0(Invalid transmission type) Total Line Attributes: 2 Access-Loop-Id: Dslam_10 atm 10/7:0.0 DOWN Neighbor: DSLAM_10 Line-State: 2(IDLE) Dsl-Type: 0(Invalid transmission type) Total Line Attributes: 2 Access-Loop-Id: Dslam_10 atm 2/0:0.0 UP Neighbor: DSLAM_10 Actual-Data-Rate-Upstream: 1184(kbps) Actual-Data-Rate-Downstream: 8064(kbps) Attainable-Data-Rate-Upstream: 1184(kbps) Attainable-Data-Rate-Downstream: 9408(kbps) Line-State: 1(SHOWTIME) Dsl-Type: 0(Invalid transmission type) Total Line Attributes: 6
