colour-aware (Y.1564)

Syntax

Hierarchy Level

Description

Configure Y.1564 color (green or yellow) information for a service, for Ethernet frames that are tagged with VLAN information using the IEEE 802.1Q standard. You specify mapping details between committed information rate (CIR), excess information rate (EIR), and their Differentiated Services Code Point (DSCP) values.

The software assigns a higher discard precedence to frames that conform to the EIR (known as yellow colored frames) than that assigned to frames that conform to CIR (known as green colored frames). You should expect yellow frames to be dropped first when congestion is encountered at the service layer. Frames that do not conform to either CIR or EIR (known as red colored frames) are dropped at the interface.

Default

Color-blind mode. Color‑blind mode ignores any prior color setting and evaluates the packet solely against its own rates.

Options

cir-pcp binary-number

Configure the IEEE 802.1p CoS Priority Code Point (PCP) Ethernet field value for committed information rate (CIR) traffic (also known as green traffic).

  • Range: binary numbers in the range from 000 to 111.

eir-pcp binary-number

Configure the IEEE 802.1p CoS PCP Ethernet field value for excess information rate (EIR) traffic (also known as yellow traffic).

  • Range: binary numbers in the range from 000 to 111.

    The most significant bit (the leftmost) is the drop eligibility indicator (DEI) Ethernet field value for yellow traffic. If 0, the frame is not subject to discard. If 1, the frame is subject to discard under congestion conditions.
