Hierarchy Level

[edit interfaces at-fpc/pic/port atm-options scheduler-maps map-name forwarding-class class-name]

Release Information

Statement introduced before JUNOS Release 7.4.

Description

For ATM2 IQ interfaces only, define the EPD threshold on a VC. The EPD threshold is a limit on the number of transmit packets that can be queued. Packets that exceed the limit are discarded.

Default

If you do not include either the epd-threshold or the linear-red-profile statement in the forwarding class configuration, the JUNOS software uses an EPD threshold based on the available bandwidth and other parameters.

Options

cells—Maximum number of cells.

Range: For 1-port and 2-port OC12 interfaces, 1 through 425,984 cells. For 1-port OC48 interfaces, 1 through 425,984 cells.For 2-port OC3, DS3, and E3 interfaces, 1 through 212,992 cells. For 4-port DS3 and E3 interfaces, 1 through 106,496 cells.

plp1 cells—Early packet drop threshold value for PLP 1.

Range: For 1-port and 2-port OC12 interfaces, 1 through 425,984 cells. For 1-port OC48 interfaces, 1 through 425,984 cells.For 2-port OC3, DS3, and E3 interfaces, 1 through 212,992 cells. For 4-port DS3 and E3 interfaces, 1 through 106,496 cells.
