The run mtrace command displays multicast traceroute towards specified IPv4 source and group address.


Command Syntax

run mtrace <ipv4-src-addr> [< ipv4-group-addr >]


Parameters

Parameter

Description

<ipv4-src-addr>

Specifies the source IPv4 address to trace.

< ipv4-group-addr >

Optional. Specifies the group IPv4 address to trace.


Example

  • The following example traces with multicast source:
admin@Xorplus# run mtrace 1.1.1.100
* Mtrace from 1.1.1.100 to 5.5.5.50 via group 0.0.0.0
Querying full reverse path...
 * switching to hop-by-hop:
  0  dynamic-005-005-005-050.5.5.pool.telefonica.de (5.5.5.50)
 -1  dynamic-005-005-005-005.5.5.pool.telefonica.de (5.5.5.5) PIM thresh^ 1
 -2  ? (4.4.4.4) PIM thresh^ 1
 -3  ? (3.3.3.3) PIM thresh^ 1
Round trip time 9 ms; total ttl of 3 required.
  • The following example traces with multicast source and group address: 
admin@Xorplus# run mtrace 1.1.1.100 224.1.1.1
* Mtrace from 1.1.1.100 to 5.5.5.50 via group 224.1.1.1
Querying full reverse path...
 * switching to hop-by-hop:
  0  dynamic-005-005-005-050.5.5.pool.telefonica.de (5.5.5.50)
 -1  dynamic-005-005-005-005.5.5.pool.telefonica.de (5.5.5.5) PIM (S,G) thresh^ 1
 -2  ? (4.4.4.4) PIM (RP) (S,G) thresh^ 1
 -3  ? (3.3.3.3) PIM (S,G) thresh^ 1
Round trip time 6 ms; total ttl of 3 required.

In the display result, "0" represents the switch currently executing mtrace, "-1" represents the first hop starting from the current switch and its interface IP address is 5.5.5.5.
