Key Field

Description

Size

ISDX

VID

X1_TYPE

X1 type.

0: ISDX.

1: VID.

EGR_PORT

Logical egress port number.

Configuration port mapped via REW::PORT_CTRL.ES0_LPORT_NUM. The

default is no mapping (EGR_PORT = configuration port number).

The configuration port is either the physical port or a Tx-mirror port number.

PROT_ACTIVE Protection is active. Value is IFH.ENCAP.PROT_ACTIVE.1

VSI

Virtual Switch Instance.

Default value is VSI = IFH.DST.ENCAP.GEN_IDX if

IFH.DST.ENCAP.GEN_IDX_MODE = 1 else 0.

The following conditions will change the default:

If REW::ES0_CTRL.ES0_BY_RLEG = 1 and

(IFH.FWD.DST_MODE = L3UC_ROUTING or

IFH.FWD.DST_MODE = L3MC_ROUTING)

Force VSI = 0x3ff to identify routing.

If REW::ES0_CTRL.ES0_BY_RT_FWD = 1 and IFH.ENCAP.RT_FWD = 1.

Force VSI = 0x3ff to identify routing.

COSID

Class of Service Identifier.

Value is IFH.VSTAX.MISC.COSID if

REW::PORT_CTRL.VSTAX2_MISC_ISDX_ENA = 1 else 0.

COLOR

Frame color.

Value is IFH.VSTAX.QOS.DP mapped through REW::DP_MAP.DP.

SERVICE_FRM Service frame.

Set to 1 if IFH.VSTAX.MISC.ISDX > 0 and

REW::PORT_CTRL.VSTAX2_MISC_ISDX_ENA = 1 else 0.

ISDX

Ingress Service Index.

Value is IFH.VSTAX.MISC.ISDX if

REW::PORT_CTRL.VSTAX2_MISC_ISDX_ENA = 1 else 0.

VID

IEEE VLAN identifier.

Default value is VID = IFH.VSTAX.TAG.VID.

The following conditions will change the default:

If REW::ES0_CTRL.ES0_BY_RLEG = 1 and (IFH.FWD.DST_MODE =

L3UC_ROUTING or IFH.FWD.DST_MODE = L3MC_ROUTING)

VID = IFH.DST.L3[UC|MC].ERLEG

If REW::ES0_CTRL.ES0_BY_RT_FWD = 1 and

IFH.DST.ENCAP.RT_FWD = 1

VID = IFH.DST.ENCAP.GEN_IDX.
