Enabling and Disabling Per-VC Clipping
Per-VC clipping provides an added traffic-shaping option that allows you to
modify how your ATM line responds to oversubscribed traffic. By default, per-VC
clipping is disabled on a line. However, you can enable or disable per-VC clipping
at any time.
When enabled, this option clips frames intended for an oversubscribed VC when
the number of frames in memory exceeds a predetermined limit.
Using the BCC
To enable per-VC clipping, navigate to the atm prompt (for example,
box; atm/11/1
) and enter:
clipping enabled
For example, the following command enables per-VC clipping on the ATM
interface:
atm/11/1#
clipping enabled
atm/11/1#
To disable per-VC clipping, navigate to the atm prompt and enter:
clipping disabled
For example, the following command disables per-VC clipping on the ATM
interface:
atm/11/1#
clipping disabled
atm/11/1#
Note:
Changing the state of this parameter tears down all active VCs on the
interface. The new state takes effect after VC connections are reestablished.
