Functional Descriptions

VMDS-10492 VSC7440 Datasheet Revision 4.2

The following table defines the pipeline actions associated with the pipeline point.

Note: A frame cannot be assigned both a starting point and an ending point at the same side of the queue

system. For instance, a frame cannot be injected in the analyzer at ANA_CLM and then extracted at

ANA_IN_SW. However, a frame can be injected in the analyzer and then extracted in the rewriter.

Analyzer

The following sections provides information about the functional aspects of the analyzer (ANA). The

analyzer evokes different actions based on the contents of the frame fields. The analyzer is organized

into the following blocks.

•

VCAP CLM: VCAP Classification matching—keys and actions

•

ANA_CL: Analyzer classifier

•

ANA_L3: VLAN and MSTP

•

VCAP LPM: VCAP longest prefix matching—keys and actions

•

ANA_L3: IP routing

•

VCAP IS2: VCAP Ingress Stage 2—keys and actions

•

ANA_ACL: Access Control Lists

•

ANA_L2: Analyzer Layer 2 forwarding and learning

•

ANA_AC: Analyzer Actions—forwarding, policing, statistics

REW_OU_MIP

Pipeline Actions

Pipeline Action

Description

INJ

Set when CPU-injecting a frame into the processing flow at the associated pipeline point. The

processing starts at the associated pipeline point.

INJ_MASQ

Set when CPU-injecting a frame masqueraded into the processing flow at the associated

pipeline point. The processing starts at the associated pipeline point.

XTR

Assigned to frames being redirected to the CPU. The processing ends at the associated

pipeline point. Frames copied to the CPU are not assigned a pipeline point as the processing

continues.

XTR_UPMEP

Assigned to frames being extracted to the CPU by an Up MEP (VOE). The processing ends at

the associated pipeline point. Frames copied to the CPU are not assigned a pipeline point as

the processing continues.

XTR_LATE_REW

Assigned to MPLS OAM frames by VCAP CLM to instruct the rewriter to terminate the

processing of the frame. The processing ends at the associated pipeline point.

LBK_ASM

Assigned by Up MEPs (VOE) requiring the frame to be looped. This action implies that the

processing in the rewriter is ended at the associated pipeline point and that the processing in

the analyzer after looping the frame starts at the corresponding analyzer pipeline point.

LBK_QS

Assigned by Down MEPs (VOE) requiring the frame to be looped. This action implies that the

processing in the analyzer is ended at the associated pipeline point and that the processing in

the rewriter after looping the frame starts at the corresponding rewriter pipeline point.
