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.
