Troubleshooting Commands Table B-1. mtrace Options (continued) Option Meaning -S <statint> Change the interval between statistics gathering traces to the specified number of seconds. The default value is 10 seconds. -t <ttl> Set the time to live (TTL) for multicast trace queries and responses to the value you specify. TTL equals the number of hops. The default ttl value is 127 hops. For local queries to the “all queries” multicast group, the default is one hop. -U Always request the response using unicast rather than attempting multicast first. -v Use verbose mode. In verbose mode, mtrace shows hop times on the initial trace and statistics display, as well as the route that was used to forward the initial trace. -w <wait> Set the time to wait for a trace response to the number of seconds you specify. The default wait value is 3 seconds. source is the source of the multicast tree. destination is the receiver for a particular multicast group. group is a multicast group. The default group is 224.2.0.1. If you do not specify a group, the mtrace command does not display statistics. For example, the following mtrace command specifies source 192.32.27.193, destination 192.32.199.162, and group 224.2.0.1. $ mtrace 192.32.27.193 192.32.199.162 224.2.0.1 Mtrace from 192.32.27.193 to 192.32.199.162 via group 224.2.0.1 Querying full reverse path... 0 192.32.199.162 -1 192.32.199.162 DVMRP thresh^ 1 -2 192.32.27.193 Round trip time 1039 ms; total ttl of 2 required.
