Frame Relay Question, Help

Ray1234

Frame relay configured on the interface, following is the output of:

#show fram PVC

PVC Statistics for interface Serial0/0 (Frame Relay DTE)

              Active     Inactive      Deleted       Static
  Local          0            0              0               1

Problem: Cannot ping across to the other end of the circuit, why?

Second question: What is a static PVC, I looked up the documentation and I just cannot replicate this output. My understanding is:

PVC has to be "Active" (Both ends configured); "Inactive" = Only one end configured; "deleted" = Not provisioned by service provider or DLCI non-existent on the frame-relay switch. Don't know about the last one? (Not to be confused with static DLCI to L3 address mapping)

pls provide both ends config

Ray1234

Only one end output is given. By looking at this question, I am supposed to know why I cannot ping the other end.

Thanks for the help, I did not think about the LMI.

I turned off the keepalives on the router (DTE end), here is the output:

PVC Statistics for interface Serial0/0 (Frame Relay DTE)

              Active     Inactive      Deleted       Static
  Local           1             0            0            0
  Switched       0            0            0            0
  Unused         0            0            0            0

DLCI = 102, DLCI USAGE = LOCAL, PVC STATUS = STATIC, INTERFACE = Serial0/0

PVC status = STATIC but the Local DLCI shows as "Active", rather than show up as "Static"

what happens if you turn it off on the frame switch end?

Ray1234

Output remains the same. Does not show up under static.

If the DLCI provisioned exist on the frame relay switch, the packets will go through, otherwise not.

Is this a back-to-back frame link?  Likely you aren't getting any LMI interaction (no keepalive) but have one DLCI configured locally.  There will be no verification of it. 

You simply need to have the same dlci information on both sides in order to match up.

HTH,

Scott
