Release Information

Statement introduced in Junos OS Release 10.2.

Description

Configure the mode to shape downstream ATM traffic based on either frames or cells.

Default

The default is frame-mode.

Options

shaping-mode—One of the following shaping mode parameters:

frame-mode—Shaping based on the number of bytes in the frame, without regard to cell encapsulation or padding overhead.
cell-mode—Shaping based on the number of bytes in cells, and accounts for the ATM cell encapsulation and padding overhead. The resulting traffic stream conforms to the policing rates configured in downstream ATM switches, reducing the number of packet drops in the Ethernet network
$junos-cos-shaping-mode—Variable for the shaping mode that is replaced with a value obtained from the RADIUS server when a subscriber authenticates over the interface to which the dynamic profile is attached.

byte-value—Byte adjustment value for the cell or shaping mode, or the Junos predefined variable:

$junos-cos-byte-adjust—Variable for byte adjustment that is replaced with a value obtained from the RADIUS server when a subscriber authenticates over the interface to which the dynamic profile is attached.

Range: –120 through 124 bytes
