Link Trace Cache - Dell Force10 C150 Configuration Manual

Figure 5-4. Linktrace Message and Response
MEP
Link trace messages carry a unicast target address (the MAC address of an MIP or MEP) inside a multicast
frame. The destination group address is based on the MD level of the transmitting MEP
(01:80:C2:00:00:3[8 to F]). The MPs on the path to the target MAC address reply to the LTM with an LTR,
and relays the LTM towards the target MAC until the target MAC is reached or TTL equals 0.
Task
Send a Linktrace message. Since the
LTM is a Multicast message sent to the
entire ME, there is no need to specify a
destination.

Link Trace Cache

After a Link Trace command is executed, the trace information can be cached so that you can view it later
without retracing.
Task
Enable Link Trace caching.
Set the amount of time a trace result is cached.
Set the size of the Link Trace Cache.
Display the Link Trace Cache.
