Usually this indicates problem with encapsulation or hardware (interface or
cable).
1. Check on the frame-relay router, if you are using right encapsulation:
frame-relay IETF !!!
2. Try switch to the second serial interface on your the router and see if
the problem persist.
3. Try using HDLC encapsulation (the default one) and connect the serial
interface to the router with a good serial interface. (Don't forget to set
up clock rate on one of the end with DCE cable!!!)
Debug interface: #debug serial interface
The myseq, mineseen and yourseen should read the same. If not try using
different cable.
If the line protocol still goes up/down you have bad Serial interface on
your router.

Hi all
I've been configuring a cisco 2600 dual wic with three subinterfaces on
serial 0/1.
If i leave the the keepalive to 10 sec, the line protocol on the serial 0/1
keeps coming up but going down after a couple of seconds. The only way i can
keep the line protocol up is (no keepalive) on seial 0/1. Iam not sure
whether this is the best way of sorting out this problem.Here is the current
config on this serial port
Serial0/1 is up, line protocol is up
Hardware is PowerQUICC Serial
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation FRAME-RELAY IETF, loopback not set
Keepalive not set
Broadcast queue 0/64, broadcasts sent/dropped 96/227, interface broadcasts
96
Last input 00:00:17, output 00:00:12, output hang never
Last clearing of "show interface" counters 01:26:53
