Tracing VRRP Operations
To trace VRRP operations, include the traceoptions statement at the [edit protocols vrrp]
hierarchy level.
By default, VRRP logs the error, data carrier detect (DCD) configuration, and routing
socket events in a file in the /var/log directory. By default, this file is named /var/log/vrrpd.
The default file size is 1 megabyte (MB), and three files are created before the first one
gets overwritten.
To change the configuration of the logging file, include the traceoptions statement at the
[edit protocols vrrp] hierarchy level:
[edit protocols vrrp]
traceoptions {
file <filename> size <size> ;
flag flag;
no-remote-trace;
}
flag flag;
You can specify the following VRRP tracing flags:
•
all—Trace all VRRP operations.
•
database—Trace all database changes.
•
general—Trace all general events.
•
interfaces—Trace all interface changes.
•
normal—Trace all normal events.
•
packets—Trace all packets sent and received.
