The system view is displayed.
Step 2
Run:
mtrace query-policy
[
acl-number
]
The policy for filtering queriers is configured.
acl-number
defines the address range for reliable queriers. Based on the specified ACL, the last-
hop switch rejects the IGMP Tracert-Request packets sent by unauthorized queriers.
NOTE
l
This command takes effect only on the last hop switch, and the querier is not the last hop switch.
l
This command filers only the IGMP-Tracert-Query packets encapsulated in unicast IP packets.
l
This command is not applicable to the tracking initiated from the querier.

6.23.7 Checking the Configuration
After performing the MTrace test for the RPF path from the multicast source to the destination
host, you can view the test result.
Prerequisite
The configurations of the NQA MTrace Test function are complete.
Context
NOTE
NQA test results cannot be displayed automatically on a terminal. You must run the
display nqa results
command to view test results. By the default, the command output contains the records about only the last
five tests.
Procedure
l
Run the
display nqa-agent
[
admin-name
test-name
] [
verbose
] to view the status of the
test instance configured on the NQA client.
l
Run the
display nqa results
command to view the test results on the NQA client.
l
Run the
display nqa history
command to view the history of the NQA test.
l
Run the
display mtrace statistics
command to view the statistics of the MTrace packets.
----End
Example
Run the
display nqa-agent
command. If information about the NQA test is displayed, it means
that the test is successful. For example:
<Quidway>
display nqa-agent admin aa verbose
nqa test-instance admin aa
test-type mtrace
destination-address ipv4 11.1.6.4
mtrace-source-address ipv4 11.1.0.1
mtrace-group-address ipv4 225.0.0.1
nqa status : normal
