Dear Michael,
Is that a back to back link or having a frame relay switch in
between?
if back to back, try "no frame-relay keepalive" to disable the
LMI(you don't need it cause no FR switch talk to you)
if have FW switch in
between, try to change another frame-relay lmi type(ansi, cisco, etc.)
Regards,
Howard

Experts,
Having a problem with a Frame Relay interface, for some
reason cant get
router in up up state with framerelay switch.
Encapsulation is
being austosensed to HDLC ?? Instead of Frame-relay.
Serial2/0 is up, line
protocol is up
Hardware is M4T
MTU 1500 bytes, BW 1544 Kbit, DLY 20000
usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation
HDLC, crc 16, loopback not set
Keepalive set (10 sec)
Restart-Delay is 0
secs
Last input never, output never, output hang never
Last clearing of
"show interface" counters 00:01:13
Input queue: 0/75/0/0

Queueing strategy: weighted
fair
Output queue: 1/1000/64/0 (size/max total/threshold/drops)

2 packets output, 634 bytes, 0

0 output errors, 0 collisions, 2 interface resets
0 output
buffer failures, 0 output buffers swapped out
So I staticly set its
encapsulation to Frame-relay, it goes up for a
second, then line protocol
drops.

All hardware is correct, have switched configs with router 4 and plugged
into
frame-relay switch same port as router 5, comes up no problem.
There is
clearly a problem with router 5.

So, it looks like staus enq are
not being sent or recieved.. Id think
this would be a "keepalive timer not
matching issue"
But both timers are staticly set to 10 sec, I even switched
them to 30
seconds together still timeouts ! Clockrate has been set to 64000
also.
