NOTE
l When label-type is set to control-word, run the remote-pw-id remote-pw-id command to configure
the ID of the remote end of the PW.
l When label-type is set to label-alert, run the destination-address ipv4 ip-address { lsp-masklen
mask-length | lsp-loopback loopback-address }* command to configure the destination IP address of
the PWE3 Trace test.
l When label-type is set to normal, run the destination-address ipv4 ip-address { lsp-masklen mask-
length | lsp-loopback loopback-address }* command to configure the destination IP address of the
PWE3 Trace test.
Step 7 Run:
local-pw-id local-pw-id
The ID of the local end of the PW is configured.
Step 8 (Optional) Run the following commands to configure other parameters for the PWE3 Trace 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.
l To configure the LSP EXP value, run the lsp-exp exp command.
l To configure maximum hops of the PWE3 Trace test, run the tracert-hopfailtimes
timescommand.
l To configure the initial TTL value and maximum TTL value of the packet, run the tracert-
livetime first-ttl first-ttl max-ttl max-ttl command.
Step 9 Run:
start
The NQA test is started.
Select the start mode as required because the start command has several forms.
l To perform the NQA test immediately, run the start now [ end { at [ yyyy/mm/dd ]
hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } ]
command.
The test instance is started immediately.
l To perform the NQA test at the specified time, run the start at [ yyyy/mm/dd ] hh:mm:ss
[ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime
{ seconds second | hh:mm:ss } ] command.
The test instance is started at a specified time.
l To perform the NQA test after a certain delay period, run the start delay { seconds second
| hh:mm:ss } [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } |
lifetime { seconds second | hh:mm:ss } ] command.
The test instance is started after a certain delay.
