Cisco CCNA Certification Exam: Five Frame Relay Details You Must KnowPage: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 or Go To our Certification Articles Section
When you're studying for your CCNA exam on the way to earning
this coveted Cisco certification, the details can seem overwhelming!
In this article, I'll point out five Frame Relay details that
you must keep in mind when you're on your way to the CCNA
exam!
Inverse ARP starts working as soon as you open the serial
interface. This protocol performs dynamic Frame Relay mapping,
but you don't have to enable it - it's already enabled as
soon as you enter the command "encapsulation frame-relay".
When you're configuring Frame Relay map statements manually,
remember that you're mapping the local DLCI to the remote
IP address.
When you run "show frame map", the word "dynamic"
indicates mappings created by Inverse ARP, and "static"
indicates it was manually created.
To spot possible LMI type mismatches, run "show frame
lmi". A large number of Status Timeouts indicates that
there may be an LMI problem between your router and the frame
relay switch.
This last one is for the many of you building CCNA home labs.
A frame relay switch is a great addition to your lab! While
you're busy putting the configuration together, don't forget
the global command "frame-relay switching" - it's
this command that allows a Cisco router to act as a frame
relay switch!
