tlp

Function

The tlp command configures Target Logical Ports (TLPs) of an IP FPM instance and their roles.

The undo tlp command deletes TLPs of a measurement instance.

By default, no TLP of a measurement instance is configured.

Format

tlp tlp-id { in-point | out-point } { ingress | egress }

tlp tlp-id mid-point flow { forward | backward | bidirectional } { ingress | egress }

undo tlp tlp-id

Parameters

Parameter	Description	Value
tlp-id	Specifies the ID of a TLP.	The value is an integer that ranges from 1 to 16777215.
in-point	Indicates the in-point TLP. An in-point TLP colors a target flow.	-
out-point	Indicates the out-point TLP. An out-point TLP removes the color flag from a target flow.	-
ingress	Indicates the ingress TLP. An ingress TLP only receives packets.	-
egress	Indicates the egress TLP. An egress TLP only sends packets.	-
mid-point	Indicates the TLP as a mid-point.	-
flow	Indicates the target flow.	-
forward	Indicates the forward target flow.	-
backward	Indicates the backward target flow.	-
bidirectional	Indicates the bidirectional target flows.	-

Usage Guidelines

Usage Scenario

To locate faults in IP FPM performance statistics scenarios, run the tlp command to configure TLPs in an IP FPM instance. TLPs are measurement points along the path of the target flow and compile and output the statistics. TLPs can be in-points, mid-points, or out-points.

Precautions

A TLP that functions as the in-point for the forward target flow is the out-point for the backward target flow. The TLP role specified in the tlp command applies only to the forward target flow, and the reverse of the specified role is used for the backward target flow.

Mid-points apply only to IP FPM hop-by-hop performance statistics scenarios. Therefore, you must configure flow to specify the target flow direction when specifying a TLP as a mid-point.

A TLP cannot function as both the in-point and out-point for the same unidirectional target flow.
