the connection is over serial, and I will update the firmware and check, is it possibly a hardware failure ?
and a Tellabs NTU is connected to this router through V.35 serial cable and in turn 256 Kbps line is connected to this modem through RJ45 connector. I have purchased MPLS IP VPN service over frame-relay circuit from service provider so this router is acting as CE router for service provider network. When I am changing the LMI type of the router it gets crashed, reboots itself.
I forgot to tell you one important thing, service provider gave us DLCI No 128 to be configured at our branch router but when I configure DLCI 128 on the router I get the following messages . What I can understand from these messages is that either they has configured DLCI 115 on their Frame-Relay switch or they have connected wrong Frame-Relay switch port to our router.
2000.02.03 20:44:12 Port 1 vc 115: VC 115 is inactive because the internal peer is inactive.
2000.02.03 20:44:12 Port 1 vc 115: DTE signaling wants to bring up VC 115
2000.02.03 20:44:12 Port 1 vc 128: DTE signaling taking down VC 128
2000.02.03 20:44:50 FRAME_RELAY.LMI Port 1 vc 115 (unused): state changed to Inactive at the switch2000.02.03 20:44:50 Port 1
And after configuring DLCI 115 I donâ t get these messages and DLCI gets up but when I tries to ping directly connected ip I donâ t get through.
thank you all
