Trace timer processing.timer
In the following example, tracing is enabled for all routing protocol packets. Then tracing
is narrowed to focus only on IGMP packets of a particular type. To configure tracing
operations for IGMP:
1. (Optional) Configure tracing at the routing options level to trace all protocol packets.
[edit routing-options traceoptions]
user@host# set file all-packets-trace
user@host# set flag all
2. Configure the filename for the IGMP trace file.
[edit protocols igmp traceoptions]
user@host# set file igmp-trace
3. (Optional) Configure the maximum number of trace files.
[edit protocols igmp traceoptions]
user@host# set file files 5
4. (Optional) Configure the maximum size of each trace file.
[edit protocols igmp traceoptions]
user@host# set file size 1m
5. (Optional) Enable unrestricted file access.
[edit protocols igmp traceoptions]
user@host# set file world-readable
6. Configure tracing flags. Suppose you are troubleshooting issues with a particular
multicast group. The following example shows how to flag all events for packets
associated with the group IP address.
[edit protocols igmp traceoptions]
user@host# set flag group | match 233.252.0.2
7. View the trace file.
user@host> file list /var/log
user@host> file show /var/log/igmp-trace
