run mtrace


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


Command Syntax

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


Parameters

Parameter

Description

source <ipv4-src-addr>

Specifies the source IPv4 address to trace.

group <ipv4-group-addr>

Optional. Specifies the group IPv4 address to trace.


Example

  • The following example traces with multicast source:
admin@PICOS# run mtrace source 1.1.1.100 
* Mtrace from 1.1.1.100 to 3.3.3.30 via group 0.0.0.0
Querying full reverse path...
 * switching to hop-by-hop:
  0  ? (3.3.3.30) 
 -1  ? (3.3.3.3) PIM thresh^ 1
Round trip time 3 ms; total ttl of 1 required.
  • The following example traces with multicast source and group address: 
admin@PICOS# run mtrace source 1.1.1.100 group 224.1.1.1 
* Mtrace from 1.1.1.100 to 3.3.3.30 via group 224.1.1.1
Querying full reverse path...
 * switching to hop-by-hop:
  0  ? (3.3.3.30) 
 -1  ? (3.3.3.3) PIM (S,G) thresh^ 1
Round trip time 3 ms; total ttl of 1 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 3.3.3.3.
