6.21 Configuring the PWE3 Trace Test to Check the One-
Hop PW
This section describes how to configure a PWE3 trace test to check the communications between
devices along a PW.
6.21.1 Establishing the Configuration Task
Before configuring a PWE3 trace test for a single-hop PW, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the required data. This
can help you complete the configuration task quickly and accurately.
Applicable Environment
To trace a one-hop PW using LDP as the signaling protocol, you can perform the PWE3 Trace
test on the one-hop PW.
Pre-configuration Tasks
Before configuring the PWE3 Trace test on a one-hop PW, you must correctly configure the
dynamic one-hop PW.
Data Preparation
To configure the PWE3 Trace test on a one-hop PW, you need the following data.
No.
Data
1
ID of the PW
2
Type of the PW
3
Type and number of the interface connected with the CE
4
Destination IP address and ID of the L2VC
5
(Optional) Response mode of the Echo packets, LSP EXP, maximum hops, number
of probes, TTL value, and timeout period of the packets
6
Start mode and end mode of the test
