I am stumped on a problem with our Telco here. We have a frame-relay DS3 from Verizon. This is how it's connected from the CO.
Verizon CO Frame router/switch <-> DS3 <-> Adtran Opti3 <-> OC3 fiber <-> Adtran Opti3 <-> DS3 <-> our router We started having problem two weeks ago and the circuit started bouncing. We originally had a 7500 router there. Verizon kept insisting the problem is CPE so we have tried second DS3 interface on the 7500, different card in the 7500, then finally swapping out the entire router with a 7200 and PA-T3. Verizon finally figured out there was indeed something wrong on their side and swapped out some cards on the Opti3. Now the circuit isn't going up and down but we are seeing trickling errors on the interface consistantly. They put a T-berd on our side of the dmark and monitored the circuit over the weekend. They are seeing errors coming from our router and FEBE from CO end. From our router, I am seeing errors coming from Verizon. At this point, I can't believe it's our DS3 card. We have changed the DS3 cable as well. Does anyone see any possible problem on my side of the config? Or any other ideas what could be causing this problem? interface Serial1/0 description Verizon DS3 frame-relay no ip address no ip redirects no ip unreachables no ip proxy-arp encapsulation frame-relay IETF no ip mroute-cache logging event subif-link-status logging event dlci-status-change framing c-bit cablelength 50 dsu bandwidth 44210 serial restart-delay 0 frame-relay lmi-type ansi #sh controllers ser 1/0 M1T-T3 pa: show controller: PAS unit 0, subunit 0, f/w version 3-92, rev ID 0x2800001, version 3 idb = 0x614754AC, ds = 0x61476FC4, ssb=0x614772F4 Clock mux=0x30, ucmd_ctrl=0x0, port_status=0x1 Serial config=0x8, line config=0x1B0202 maxdgram=4584, bufpool=128Kb, 256 particles rxLOS inactive, rxLOF inactive, rxAIS inactive txAIS inactive, rxRAI inactive, txRAI inactive line state: up cable type : T3 cable, received clockrate 44201430 base0 registers=0x3C800000, base1 registers=0x3C802000 rx_base0 registers=0x3C804000, rx_base1 registers=0x3C806000 mxt_ds=0x61922350, rx ring entries=124, tx ring entries=254 statring=0x3903900, statr shadow=0x61479124, stat_head=175 plus_pa: rx_statring=0x3903D40, rx_statr shadow=0x61479950, rx_stat_head=29 rxring=0x39036C0, rxr shadow=0x61478AF8, rx_head=109 txring=0x3904300, txr shadow=0x61479D7C, tx_head=185, tx_tail=191, tx_count=6 throttled=0, enabled=0 halted=0, last halt reason=0 Microcode fatal errors=0 rx_no_eop_err=0, rx_no_stp_err=0, rx_no_eop_stp_err=0 rx_no_buf=0, rx_soft_overrun_err=23, dump_err= 0, bogus=0, mxt_flags=0x2C tx_underrun_err=18, tx_soft_underrun_err=0, tx_limited=0(254) tx_fullring=538, tx_started=809952433 rx_int_count=870161881, tx_int_count=1611065176 Framing is c-bit, Clock Source is Line Bandwidth limit is 44210, DSU mode 0, Cable length is 50 rx FEBE since last clear counter 1980, since reset 179 Data in current interval (881 seconds elapsed): 1 Line Code Violations, 1 P-bit Coding Violation 1 C-bit Coding Violation 1 P-bit Err Secs, 0 P-bit Sev Err Secs 0 Sev Err Framing Secs, 0 Unavailable Secs 1 Line Errored Secs, 1 C-bit Errored Secs, 0 C-bit Sev Err Secs Total Data (last 24 hours) 2343 Line Code Violations, 637 P-bit Coding Violation, 635 C-bit Coding Violation, 260 P-bit Err Secs, 0 P-bit Sev Err Secs, 0 Sev Err Framing Secs, 0 Unavailable Secs, 418 Line Errored Secs, 260 C-bit Errored Secs, 0 C-bit Sev Err Secs No alarms detected. #sh int ser 1/0 Serial1/0 is up, line protocol is up Hardware is M1T-T3 pa Description: Verizon DS3 frame-relay ######### MTU 4470 bytes, BW 44210 Kbit, DLY 200 usec, reliability 255/255, txload 57/255, rxload 13/255 Encapsulation FRAME-RELAY IETF, crc 16, loopback not set Keepalive set (10 sec) Restart-Delay is 0 secs LMI enq sent 41313, LMI stat recvd 41313, LMI upd recvd 0, DTE LMI up LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0 LMI DLCI 0 LMI type is ANSI Annex D frame relay DTE Broadcast queue 0/256, broadcasts sent/dropped 0/0, interface broadcasts 0 Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 4d18h Input queue: 0/75/0/3084 (size/max/drops/flushes); Total output drops: 4570 Queueing strategy: fifo Output queue :0/40 (size/max) 5 minute input rate 2283000 bits/sec, 1030 packets/sec 5 minute output rate 10030000 bits/sec, 1403 packets/sec 209774076 packets input, 1379501582 bytes, 0 no buffer Received 356689 broadcasts, 0 runts, 0 giants, 0 throttles 0 parity 4829 input errors, 4748 CRC, 0 frame, 79 overrun, 0 ignored, 2 abort 259718552 packets output, 3599585926 bytes, 0 underruns 0 output errors, 0 applique, 4294967295 interface resets 0 output buffer failures, 0 output buffers swapped out 1 carrier transitions rxLOS inactive, rxLOF inactive, rxAIS inactive txAIS inactive, rxRAI inactive, txRAI inactive _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
