It actually has some really nice information about LMI. I highly recommend using the Doc CD for help. One additional advantage to using it, is you become familiar with where things are located throughout the information to allow you to find it quicker during the lab since you will not have the search function.
The task is.
10) R5 should have full status updates of DLCIs every 180 seconds.
The answer is
interface Serial0
frame-relay lmi-n391dte 18
Based on the comments of the companion guide I am guessing that full DLCI updates are sent every 6th keepalive interval.
And by using the "frame-relay lmi-n391dte 18" command I will make the DLCI updates send every 18th keepalive interval.
Since keepalives are sent every 10 seconds then the requirement that "full status updates of DLCIs every 180 seconds" would be met.
Apart from just knowing it.
Where do I find that DLCI updates are sent every 6th keepalive interval? As "sh int s0" doesn't seam to tell me.
Are my assumptions correct?
Has anyone got a link to any good material on some of these other similar looking commands?
frame-relay lmi-n391dte set full status polling counter
frame-relay lmi-n392dce LMI error threshold
frame-relay lmi-n392dte LMI error threshold
frame-relay lmi-n393dce set LMI monitored event count
frame-relay lmi-n393dte set LMI monitored event count
frame-relay lmi-t392dce set DCE polling verification timer
