Configuring Linktrace Protocol in CFM
The linktrace protocol is used for path discovery between a pair of maintenance points.
Linktrace messages are triggered by an administrator using the traceroute command to
verify the path between a pair of MEPs under the same maintenance association. Linktrace
messages can also be used to verify the path between an MEP and an MIP under the
same maintenance domain. The operation of IEEE 802.1ag linktrace request and response
messages is similar to the operation of Layer 3 traceroute commands. For more
information about the traceroute command, see the Junos OS System Basics Configuration
Guide.
Configuring the Linktrace Path Age Timer
If no response to a linktrace request is received, the request and response entries are
deleted after the age timer expires. To configure the linktrace age timer, use the linktrace
statement with the age time option at the [edit protocols oam ethernet
connectivity-fault-management] hierarchy level. The age is configured in minutes or
seconds.
Configuring the Linktrace Database Size

Configure the number of linktrace reply entries to be stored per linktrace request. To
configure the linktrace database size, use the linktrace statement with the
path-database-size path-database-size option at the [edit protocols oam ethernet
connectivity-fault-management] hierarchy level.
Display the linktrace database using the show oam ethernet
connectivity-fault-management path-database command.
