Step 2
Run:
nqa
test-instance
admin-name
test-name
The test instance view is displayed.
Step 3
Run:
ttl
number
The TTL value, that is, the maximum hops traced in max-hop mode is set for the IGMP Tracert-
Request packet.
Step 4
Run:
tracert-livetime
first-ttl
first-ttl
max-ttl
max-ttl
The maximum hops traced in hop-by-hop mode is set.
first-ttl
must be set to 1.
Step 5
Run:
mtrace-response-address
ipv4
ip-address
[
ttl
value
]
The destination IP address and TTL of the IGMP Tracert-Response packet are set.
Step 6
Run:
mtrace-query-type
last-hop
The last-hop switch is specified to initiate the MTrace query to the multicast source.
When multiple switchs are connected to the specified host, RPF check query from different
switchs may be different. Therefore, you can uniquely identify an RPF path by specifying the
last-hop switch.
When running this command, you must specify the IP address of the last-hop switch.
Step 7
Run:
mtrace-last-hop-address
ipv4
ip-address
The IP address of the last-hop switch is specified.
If non-Huawei devices are deployed in the multicast network, this step is mandatory.
Step 8
Run:
source-address
ipv4
ip-address
The source IP address of the IGMP Tracert-Request packet is configured. The address must be
the address of the local interface.
If non-Huawei devices are deployed in the multicast network, this step is mandatory.
Step 9
Run:
timeout
time
The timeout period for waiting for the IGMP Tracert-Response packet is set.
Step 10
Run:
probe-count
number
The maximum number of times for the querier to initiate MTrace operations in the timeout
situations is set. The querier re-initiates an MTrace operation if receiving no IGMP Tracert-
Response packet within the timeout period.
Step 11
Run:
quit
