6.18.2 Configuring the LSP Traceroute Parameters for the LDP
Tunnel
This part describes how to set parameters for an LDP LSP traceroute 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 lsptrace
The test type is set to LSP Traceroute.
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
Traceroute 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 Traceroute test, if the lsp-replymode no-reply command is configured, the
test result displays that the test fails regardless of whether the test 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 LSP EXP value, run the lsp-exp exp command.
l To configure after how many hops the test is considered failed, run the tracert-
hopfailtimes timescommand.
l To configure the initial and the maximum TTL values of the packet, run the tracert-
livetime first-ttl first-ttl max-ttl max-ttl command.
Step 7 Run:
