6.15 Configuring the LSP Ping Test
This section describes how to configure a Label Switched Path (LSP) ping test to check the
operating status of the LSP.
6.15.1 Establishing the Configuration Task
Before configuring an LSP ping test, 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
The NQA LSP Ping test can be used to test the reachability of the following types of Label
Switched Paths (LSPs) and collect statistics about Link State Advertisement (LSA).
l LSP tunnels
After the test parameters are configured and the test is started,
1. NQA creates an MPLS Echo-Request packet and adds the address 127/8 to the IP header
as the destination IP address. The packet is forwarded along the specified LSP in the MPLS
network.
2. The egress monitors port 3503 that sends Echo packets.
3. The ingress collects the test results based on the received Echo packets.
Pre-configuration Tasks
Before configuring the LSP Ping test, you need the following configuration:
l LSP tunnel
Data Preparation
To configure the LSP Ping test, you need the following data.
No.
Data
1 Administrator name and test name
2 For the LSP tunnel: destination IP address and mask of the LSP Ping test
3 (Optional) Parameters of the LSP Ping test, including the response mode of the Echo
packet, packet size, TTL, LSP EXP value, padding character, timeout period of the
packet, probe times, test interval, and percentage of the failed NQA tests
4 Start mode and end mode of the test
