Cisco SCE 8000 CLI Command Reference

Chapter 2 CLI Command Reference

virtual-links index direction

• Create and apply a virtual links policy with the Global Controllers template.

The policy is managed and applied through the GUI or API.

• Create the virtual links and optionally set any specific bandwidth configuration in the Global

Controllers.

Virtual links are created and managed in the Cisco SCE through a set of CLI commands.

• Set the virtual link names in the CM.

The virtual link names are set using a command line utility (CLU) in the CM. These names are used

in the Virtual Links Reports.

Direction

Virtual links are directional. In the CLI commands, a virtual link is always identified by both the index

number assigned to the virtual link and the direction (upstream or downstream).

Always use the direction keyword and specify upstream or downstream.

Global Controller (GC) Templates

The virtual links policy created in the SCA BB console specifies Global Controllers that will be used as

bandwidth templates for the virtual links. When a new virtual link is created, it receives a set of the

directional template VL Global Controllers with their PIR values as configured in the SCA BB console.

In some cases, you may want to modify the PIR values of a particular GC template for use with a

particular virtual link:

• Use the set-pir keyword with the desired PIR value to change the PIR value of a specified GC

associated with a specified virtual link.

• Use the reset-pir keyword with no PIR values to reset the PIR values of a specified GC to the

original values, as configured through the console.

Global Controllers–Relative Index

To specify the GC, use the gc keyword and then indicate the relative GC index. This number is the

relevant GC as found in the GC configuration for the specified direction.

GC numbering starts at 0 for the default BWC in each direction, so the third user-configured GC, for

example, is number 3. In the GC configuration illustrated in Figure 2-3, the relative index for the P2P

GC is 2 for upstream and 3 for downstream.

Note Each GC also has an absolute index. In Figure 2-3, six GCs are configured and each one is identified

internally by a unique index. This absolute index is not needed to identify a particular GC in these

commands.
