Link Trace Cache - Dell Force10 S4810P Configuration Manual

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 tar get MAC address reply to the L TM 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.
