RE: Frame Relay Status - deleted

Don't always believe what you read.... Physical problems leading to
down/down will not show deleted but up/down (LMI problems) will.
 
R4(config)#do sh frame pvc
 
PVC Statistics for interface Serial0/0/0 (Frame Relay DTE)
 
              Active Inactive Deleted Static
  Local 9 0 0 0
  Switched 0 0 0 0
  Unused 0 0 0 0
 

R4(config)#int s0/0/0
R4(config-if)#frame map ip 150.100.24.6 666 broad
R4(config-if)#exit
R4(config)#int s0/0/0.1 point-to-point
R4(config-subif)#frame int 777
R4(config-fr-dlci)#exit
R4(config-subif)#exit
 
R4(config)#do sh frame pvc | in 666|777
DLCI = 666, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0
DLCI = 777, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE =
Serial0/0/0.1
 

a couple minutes later....
 
R4(config)#do sh frame pvc | in STATUS
DLCI = 402, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 405, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 406, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 412, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 415, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 416, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 422, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 425, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 426, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0/0
DLCI = 666, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0
DLCI = 777, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0.1
 

Change LMI...
 
R4(config)#int s0/0/0
R4(config-if)#frame lmi-type ansi
 

Soon....
 
R4(config-if)#
*Nov 24 01:17:39.018: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Serial0/0/0, changed state to down
 

Now look:
 
R4(config-if)#do sh frame pvc | in STATUS
DLCI = 402, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 405, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 406, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 412, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 415, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 416, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 422, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 425, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 426, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 666, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0
DLCI = 777, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0.1
R4(config-if)#
 
It still remembers what was learned before... Only changes what is/was
working.
 
Reload and see what happens...
 
R4#sh frame pvc | in STATUS
DLCI = 666, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0
DLCI = 777, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0.1
R4#
 
No learned ones at all, but still DELETED state.
 
R4#sh int s0/0/0 | in up
Serial0/0/0 is up, line protocol is down
  LMI enq sent 15, LMI stat recvd 0, LMI upd recvd 0, DTE LMI down
  LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0
     DCD=up DSR=up DTR=up RTS=up CTS=up
R4#
 
Try changing things at physical now. If you can touch the frame switch,
just shut the interface down.
 
R4#
*Nov 24 01:26:14.891: %LINK-3-UPDOWN: Interface Serial0/0/0, changed state
to down
 
Now you'll have down/down.
 
R4#sh frame pvc | in STATUS
DLCI = 666, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0
DLCI = 777, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE =
Serial0/0/0.1
 
Nothing really changed, so try reloading...
 
R4#sh int s0/0/0 | in up|down
Serial0/0/0 is down, line protocol is down
  LMI enq sent 0, LMI stat recvd 0, LMI upd recvd 0, DTE LMI down
  LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0
  FR SVC disabled, LAPF state down
     DCD=down DSR=down DTR=up RTS=up CTS=down
R4#
 
R4#sh frame pvc | in STATUS
DLCI = 666, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0
DLCI = 777, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE =
Serial0/0/0.1
R4#
 
So physical problems will yield INACTIVE. LMI problems will yield DELETED.

Now, I could be remembering things wrong (I don't have routers in front of
me at the moment) but I'm pretty sure that if you have a physical problem or

not receiving LMI you get an INACTIVE status because it can't be
verified.... If you get a link up/up but no LMI, you'll get LOCAL or STATIC
(part of how we do back-to-back frame).

But you are correct for the misconfiguration part, as noted before, that if
you don't match the frame switch things will be bad.

Ron,
       I will list all possible states for a PVC in frame-relay and what
they mean:

Active : Your PVC is active and can pass traffic.

Inactive: Your local connection to FR is operational,but the remote router's

connection is not operational

Deleted: You are not receiving LMIs,physical layer encountered a problem or
Misconfiguration(mismatch of DLCI values between the switch and the router).

HTH,
Tarun
