Re: Neebie to list, need help [7:54904]
the tx/rx loads aren't that great and as it is a t-1 interface the amount of traffic isn't that great. the thing of interest is the interface description - link to uuwho. they have been having significant latency issues. the url may not make it but i posted it below. it describes some of their travails. we use them as well and have seen similar problems yesterday and today. nothing to troubleshoot but you do need to let your users know what is going on with the provider. here is the url >http://www.matrixnetsystems.com/ea/advisories/20021003_instant_alert.jsp hope it helps. - Original Message - From: "Chuck's Long Road" To: Sent: Friday, October 04, 2002 3:29 PM Subject: Re: Neebie to list, need help [7:54904] > in line ( like the skates ) below > > -- > > > > """"Kerpal.Abdar"""" wrote in message > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > Hi All, I am in need of some help.

Neebie to list, need help [7:54904]
Hi All, I am in need of some help. Can anyone tell me what "drops" mean when I issue a "show interface" on a Cisco router? Is this something bad and if so what can I do to fix it? Serial0/0 is up, line protocol is up Hardware is DSCC4 with integrated T1 CSU/DSU Description: LINK TO UUNET MTU 1500 bytes, BW 1536 Kbit, DLY 2 usec, reliability 255/255, txload 18/255, rxload 64/255 Encapsulation FRAME-RELAY IETF, loopback not set Keepalive set (10 sec) LMI enq sent 145889, LMI stat recvd 145889, 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 0/64, broadcasts sent/dropped 0/0, interface broadcasts 0 Last input 00:00:03, output 00:00:04, output hang never Last clearing of "show interface" counters 2w2d Queueing strategy: fifo Output queue 0/40, 516 drops; input queue 0/75, 999 drops 5 minute input rate 389000 bits/sec, 68 packets/sec 5 minute output rate 113000 bits/sec, 64 packets/sec 21344933 packets input, 3254757193 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 1 input errors, 0 CRC, 1 frame, 0 overrun, 0 ignored, 0 abort 27242775 packets output, 1682958597 bytes, 0 underruns 0 output errors, 0 collisions, 3 interface resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions DCD=up DSR=up DTR=up RTS=up CTS=up I am experiencing a lot of latency on the network and I am starting to troubleshoote to see what could be causing it. I noticed that on this link the inbound rate tends to spike to full line rate which may be the cause but not sure yet. Thanks.
