Release Information

Statement introduced in Junos OS Release 10.2.

Variable $junos-cos-byte-adjust-cell introduced in Junos OS Release 13.1R1.

Description

Configure the mode to shape downstream ATM traffic as cells.

Options

bytes—Byte adjustment value for the cell-mode or frame-mode shaping options.

$junos-cos-byte-adjust—Predefined 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.

cell-mode-bytes cell-mode-bytes—Shaping is 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-byte-adjust-cell—Predefined variable for the cell mode shaping. This variable can not be used when the overhead-accounting bytes bytes option is configured.

Best Practice: We recommend using the cell-mode-bytes cell-mode-bytes option rather than the bytes option.

Range: –120 through 124 bytes

Note: If you specify a value for the bytes bytes option, you cannot specify a value for either the cell-mode-bytes option.

Note: Cell mode is supported only on logical interfaces and interface sets; it is not supported on physical interfaces (ifd or ifd-remaining).

Default: The default is frame-mode.

Required Privilege Level
