6.15.2 Configuring the LSP Ping Test Parameters for the LDP
Tunnel
Before performing an LDP LSP ping test, you need set parameters for the LSP ping test.
Context
Do as follows on the NQA client:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
nqa test-instance admin-name test-name
An NQA test instance is created and the test instance view is displayed.
Step 3 Run:
test-type lspping
The test type is set to LSP Ping.
Step 4 Run:
lsp-type ipv4
The tunnel type is set to be the LSP tunnel.
Step 5 Run:
destination-address ipv4 ip-address { lsp-masklen masklen | lsp-loopback loopback-
address }*
The destination IP address to be tested is configured.
Step 6 (Optional) Perform the following as required to configure other parameters for the LSP Ping
test:
l To configure the response mode of the Echo packet, run the lsp-replymode { no-reply |
udp | udp-via-vpls | udp-router-alert | level-control-channel } command.
NOTE
In a uni-directional LSP Ping test, if the lsp-replymode no-reply command is configured, the test
result displays that the test fails regardless of whether the test, actually, is successful or fails. If the test
is successful, the test result also displays the number of the timeout packets. If the test fails, the test
result displays the number of the discarded packets.
l To configure the source IP address, run the source-address ipv4 ip-address command.
l To configure the packet size, run the datasize size command.
NOTE
The sum of datasize and the size of the packet header should be less than the MTU of the interface;
otherwise, the test may fail.
l To configure the maximum TTL value of the packet, run the ttl number command.
l To configure the LSP EXP value, run the lsp-exp exp command.
