link problem

[davila_jc]

I have a link with problem, the link is restarting more o less one time for hour, the hardware link is correct, the carrier (isp)check it with a loop without problem, then configured debugs in router and i give it this:

Mar 30 11:37:52 GMT: Serial0/1/0(out): Status, myseq 87, yourseen 86, DCE up

Mar 30 11:38:00 GMT: DTE idb->dte_interface = DTE

Mar 30 11:38:00 GMT: Dscc4(Serial0/1/0): DCD is down.

Mar 30 11:38:02 GMT: %LINK-3-UPDOWN: Interface Serial0/1/0, changed state to down

Mar 30 11:38:03 GMT: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1/0, changed state to down

Mar 30 11:38:30 GMT: DTE idb->dte_interface = DTE

Mar 30 11:38:30 GMT: Dscc4(Serial0/1/0): DCD is up.

Mar 30 11:38:32 GMT: %LINK-3-UPDOWN: Interface Serial0/1/0, changed state to up

Mar 30 11:38:32 GMT: Serial0/1/0(in): StEnq, myseq 0

Mar 30 11:38:32 GMT: Serial0/1/0(out): Status, myseq 1, yourseen 1, DCE up

Mar 30 11:38:33 GMT: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1/0, changed state to up

Mar 30 11:38:42 GMT: Serial0/1/0(in): StEnq, myseq 1

Mar 30 11:38:42 GMT: Serial0/1/0(out): Status, myseq 2, yourseen 2, DCE up

this is the conf:

interface Serial0/1/0

bandwidth 192

ip address 192.168.158.34 255.255.255.252

encapsulation frame-relay

load-interval 30

frame-relay traffic-shaping

frame-relay interface-dlci 505

class 384

frame-relay lmi-type ansi

frame-relay intf-type dce

The problem seems to be with LMI, not your link. Can you confirm that the device plugged in to the end is using the same type of LMI (ANSI) ?

Is autodetect, isp say they.

[sundar.palaniappan]

Why do you have the command ' frame-relay intf-type dce' in your configuratation. Your interface should be DTE unless you are the Service provider (Telco).

Try removing the command check the status.

HTH,

[davila_jc]

no, the isp not support dce.

[pkhatri]

That is really odd.. In fact, if the ISP does not support DCE functionality, how will LMI inform you about the DLCIs that are configured by the provider ?

I would remove the following 2 commands to see if the link comes up:

frame-relay lmi-type ansi

frame-relay intf-type dce

Hope that helps - pls rate the post if it does.

This is the configuration in site telco:

PE-MEX-5#sh frame-relay pvc 505

PVC Statistics for interface Serial10/0/2:4 (Frame Relay DTE)

DLCI = 505, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial10/0/2:4.
