Virtual Link Names
Virtual Link Names
Each virtual link represents a single interface on the CMTS device and the virtual link name comprises
the CMTS device name and the interface name. The virtual links are named according to the following
naming convention:
<Device name>_<Interface name>
•
<Device name>—This portion of the name is set when configuring the CMTS in the vlink.cfg
configuration file.
•
<Interface name>—This portion of the name identifies the specific CMTS interface including the
direction and the interface index. This information is how the CMTS describes the interface
internally and it is retrieved from the CMTS device by using SNMP.
– The direction portion of the virtual link name indicates the virtual link direction. Values can be
upstream or downstream.
– The interface index indicates the specific interface on the CMTS of the virtual link.
This is a sample virtual link name for a CMTS device named Device-1:
Device-1_CMTS1/0-upstream 1
If a downstream virtual link contains two channels, then the virtual link names are displayed as:
<Device name>_<Interface name>-L<index of the primary channel>
or
<Device name>_<Interface name>-W

cascade mode, both the active and standby SCEs are synchronized with CMTS device data.
– Not-done—The SCE (or one of the SCEs in cascade mode) is not synchronized with all CMTS
device data. Use the p3vlink --resync -n <sce which manages the device> command to perform
the synchronization operation.
– Sync-in-process—When VLM detects configuration changes, the change needs to be sent to the
SCE. During the update process, the VLM changes the sync state to Sync-in-process.
For successful updates, the SCE sync state is set to Done, else the value is set to Not-Done.
•
Sync state with Collection Manager:
– Done—The Collection Manager is fully synchronized with CMTS device information.
– Not-done—The CM is not synchronized with all CMTS device data. Use the
p3vlink --resync -n <sce which manages the device> command to perform the synchronization
operation.
– N/A—The SCE to which the CMTS device belongs, is not connected to any Collection
Manager.
– Sync-in-process – When VLM detects configuration changes, the change needs to be sent to the
Collection Manager. During the update process, the VLM changes the sync state to
Sync-in-process.
For successful updates, SCE sync state is set to Done, else the value is set to Not-Done.
•
Last Query Status:
– Not started—Query operation for the device was not started since the last SM boot.
– Completed—Last query was completed successfully.
– Failure—Last query failed to complete.
– Waiting for query—Query operation is in queue waiting for resources.

Monitoring Virtual Links Using the Reporter
Monitoring Virtual Links Using the Reporter
The Cisco SCA BB includes a Reporter tool that allows you to produce reports based on the traffic
analysis performed by the SCE platform. The information is sent from the SCE platform and is stored in
a database. The Reporter can query and retrieve information from the database and present the results in
a comprehensive range of reports.
The Reporter includes the Virtual Links Monitoring group of report templates that allow you to view
statistics of bandwidth or volume of traffic used by a virtual link. The reports are provided per service
usage counter for the total volume used by the virtual link. The volume consumption can be displayed
per service for the virtual link. The reports are provided per channel.
Each report can be filtered to focus on a virtual link ID, a virtual link name, a virtual link direction, or
a combination of the virtual link identifiers.
The Virtual Links Monitoring group includes these report templates:
•
VLink Bandwidth per Service—Shows the distribution of bandwidth among the different service
usage counters defined in the system for all subscribers.
•
VLink Aggregated Usage Volume per Service—Shows the total volume of traffic (upstream and
downstream) for each service usage counter.
•
VLink Bandwidth per Package—Shows the distribution of bandwidth among the different packages
defined in the system for selected vlinks.
•
VLink Hourly Usage Volume per Service—Shows the distribution of volume among the different
service usage counters defined in the system, grouped by hour.
•
VLink Daily Usage Volume per Service—Shows the distribution of volume among the different
service usage counters defined in the system, grouped by day.
•
Daily Peak BW for all VLinks—Shows the daily value of the maximum bandwidth (1-hour or 2-hour
average) for all virtual links.
•
Total Active Subscribers per VLink—Shows the number of active subscribers for a selected vlink.
•
VLink Bandwidth per Channel—Shows the distribution of bandwidth among the different channels
for selected vlinks.
•
Top Subscribers per VLink—Shows a list of the top subscriber volume consumption in a specific
hour or day for a selected Vlink.
•
Average Bandwidth per Subscribers per VLink—Shows the average bandwidth for a specific
subscriber for a selected vlink.
•
Accumulated Bandwidth Distribution per VLink—Shows the accumulated bandwidth distribution
for a selected vlink.

Creating a New Report Instance Using SCA Reporter
To create a new report instance using the SCA Reporter, complete these steps:
Step 1
Go to the SCA BB console. From the Tools menu, choose Reporter.
The Reporter opens and the Templates tab appears.
Step 2
In Templates view, expand the Virtual Links Monitoring group.
Step 3
Right-click a report instance (for example, VLink Bandwidth per Service).
A popup menu appears.
Step 4
From the menu, choose New.
The New Report Wizard dialog box appears (Figure 5-1), allowing you to configure the new report.
Figure 5-1
Step 5
New Report Wizard Dialog Box
In the Report name field, enter the name of the report instance.
The default report name is VLink Bandwidth per Service #1. (If you create another report instance
from this report template, it is named VLink Bandwidth per Service #2, and so on. You can rename
report instances.)
