At one stage we were running serious CRC's on the line, but our local telco' sorted out the line problem. They just haven't cleared their counters. The errors and CRC's showing their side is still from looooong ago ;-) -----Original Message----- From: Creighton Bill-BCREIGH1 [mailto:[EMAIL PROTECTED]] Sent: 11 October 2002 10:52 To: [EMAIL PROTECTED] Subject: RE: Need help with link utilisation [7:55347]
Maybe a dumb observation, but: Why are input errors and CRC's so dramatically higher on the ISP side, wouldn't the constant CRC retransmit requests increase the utilization? Excessive line noise or transmission probs? -----Original Message----- From: John Botha (Mnet) [mailto:[EMAIL PROTECTED]] Sent: Friday, October 11, 2002 3:20 AM To: [EMAIL PROTECTED] Subject: RE: Need help with link utilisation [7:55347] The following sh int from both sides: Our side: MNET4500>sh int s1 Serial1 is up, line protocol is up Hardware is HD64570 Description: 512Kb Internet SOLUTION CCT# 64-63487-11 Internet address is 196.6.242.90/30 MTU 1500 bytes, BW 512 Kbit, DLY 20000 usec, rely 255/255, load 36/255 Encapsulation HDLC, loopback not set, keepalive set (10 sec) Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 1w0d Input queue: 0/75/0 (size/max/drops); Total output drops: 1720 Queueing strategy: weighted fair Output queue: 0/1000/64/1707 (size/max total/threshold/drops) Conversations 0/96/256 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) 5 minute input rate 470000 bits/sec, 59 packets/sec 5 minute output rate 74000 bits/sec, 55 packets/sec 20649049 packets input, 2472568997 bytes, 0 no buffer Received 60233 broadcasts, 0 runts, 0 giants, 0 throttles 96 input errors, 95 CRC, 44 frame, 0 overrun, 0 ignored, 12 abort 18034063 packets output, 3701447186 bytes, 0 underruns 0 output errors, 0 collisions, 66 interface resets 0 output buffer failures, 0 output buffers swapped out 8 carrier transitions DCD=up DSR=up DTR=up RTS=up CTS=up Theirs: Serial4/4 is up, line protocol is up Hardware is M8T-X.21 Description: mnet | B1:TT4:L | 64-63487-11 Internet address is 196.6.242.89/30 MTU 1500 bytes, BW 512 Kbit, DLY 20000 usec, rely 255/255, load 232/255 Encapsulation HDLC, crc 16, loopback not set Keepalive set (10 sec) Last input 00:00:05, output 00:00:00, output hang never Last clearing of "show interface" counters never Input queue: 0/75/0 (size/max/drops); Total output drops: 1 Queueing strategy: weighted fair Output queue: 0/1000/64/1 (size/max total/threshold/drops) Conversations 0/32/256 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) 30 second input rate 78000 bits/sec, 58 packets/sec 30 second output rate 467000 bits/sec, 63 packets/sec 16910473 packets input, 3203937235 bytes, 0 no buffer Received 0 broadcasts, 177 runts, 7 giants, 0 throttles 11225 input errors, 11081 CRC, 0 frame, 0 overrun, 0 ignored, 144 abort 19484732 packets output, 1636048060 bytes, 0 underruns 0 output errors, 0 collisions, 6 interface resets 0 output buffer failures, 0 output buffers swapped out 7 carrier transitions DCD=up DSR=up DTR=up RTS=up CTS=up --More-- Regards, John Botha E-mail: [EMAIL PROTECTED] -----Original Message----- From: Magondo, Michael [mailto:[EMAIL PROTECTED]] Sent: 11 October 2002 09:48 To: [EMAIL PROTECTED] Subject: RE: Need help with link utilisation [7:55347] John Are you sure both interfaces have the same bandwidth configured? Michael -----Original Message----- From: John Botha (Mnet) [mailto:[EMAIL PROTECTED]] Sent: 11 October 2002 09:04 AM To: [EMAIL PROTECTED] Subject: Need help with link utilisation [7:55347] Hi group I have a problem that is currently scrambling my noodle. Our link to our ISP shows up as under utilized from a show interface command, most often sitting at less than 100/255. I questioned the slow response during working hours with one of their engineers, and his interface to us is showing at running at greater than 200/255 at the same time that my receiving interface is showing less than 100/255. Surely transmitter and receiver interfaces should show the same load? Any help and/or ideas would be appreciated.
