3.8.1.3

VCAP ES0 Port Configuration

The rewriter configures VCAP ES0 through REW:PORT:PORT_CFG.ES0_ENA. If ES0 is disabled,

frames transmitted on the port are not matched against rules in ES0.

3.8.2

VCAP IS1

This section provides information about the IS1 keys and associated actions.

IS1 supports six different keys. The main characteristics of these keys are listed in the following table.

3.8.2.1

IS1 Entry Key Encoding

All frame types are subject to the three IS1 lookups. The VCAP IS1 port configuration (VCAP_S1_CFG)

determines the key generated for each lookup. Keys that are applicable to multiple frame types (for

instance S1_NORMAL) contain frame type flags inside the key that indicate the originating frame type. In

addition, certain key fields are overloaded with different frame fields depending on the frame type flag

settings.

The following illustration shows the entry fields are available for quad, half, and full keys in IS1.
