epd-threshold

epd-threshold (forwarding class)

Syntax

(epd-threshold cells | linear-red-profile profile-name);

Hierarchy Level

[edit interfaces interface-name atm-options scheduler-maps map-name forwarding-class class-name]

Description

For ATM 2 interfaces only, define the early packet discard (EPD) threshold on a virtual circuit (VC). When a beginning of packet (BOP) cell is received, the VC's queue depth is checked against the EPD threshold. If the VC's queue depth exceeds the EPD threshold, the BOP cell and all subsequent cells in the packet are discarded.

Default

EPD threshold is unregulated.

Options

cells—Maximum number of cells.
Range: For scheduling parameters associated with forwarding class, 0 through 32,768 cells.

The remaining option is described separately.

Usage Guidelines

See Configure ATM 2 VC Tunnel CoS Components.
