Getting slow !

[menny10]

I have a Cisco 1600 router on a dsl, in this week, is getting slow browsing in internet, my ISP, say that i get some crs or somethig like that, and some collisions on my side, I really have a litle knowledge of cisco commands,what can i do !



Thanks.

 

[hjm3857]

can you telnet to the device and capture the output of the command

show tech-support

and paste it into this thread?

As a note: please remove any IP address, hashed passwords, SNMP community strings etc for your own security.

If you are not comfortable running that command, I can give you some other options, but the show tech-support data would be the best.

hi, hjm, i can´t copy all the pages that come after type the command show tech-support, in telnet, how come i copy all the pages one after another, sorry, and by the way,
you know how can reset my couters,!

I really apreciate any HELP !

 

[menny10]

here you go.


by the way this morning the service is fine and fast, but i cant tell in a hour or some thig. here yoe have the result of that commnad in telnet.

-----------------------------------------------------------
hopes this work,

I really apreciate any help.

 

[MrvNDMrtN]

So this has just started happening all of a sudden?

I suggest changing the cable to the splitter first.

You should also reset the counters and watch the errors grow.

If it is consistently growing, then it maybe to do with the card and it needs to be replaced.

Otherwise you could do further testing and shut your ethernet interface for a while and isolate this fault with your provider. What the?!?!

 

[menny10]

ok,
By the way just change the cable to the switch, and then i need to reset de counter, how can i do it,


thanks,

 

[hjm3857]

To clear the counters

you must be in exec mode (command is enable)

the the command is

clear counters interface serial0

I have copied a few significant lines from the Show Tech, the come from the Serial 0 Interface statistics:

reliability 223/255, txload 31/255, rxload 23/255

This is a 1 byte reliability metric. It has a value of 0 - 255 with 255 being perfect. you have a value of 223. This is calculated from the quantity of data seen on the Interface, and the quantity of damaged data seen on the interface. You are seeing roughly a 10% loss of data. If you look at the way TCP/IP handles data loss you will understand that a 10% loss of packets could result in an exponentially larger loss of performance.

1379811 input errors

This is the total count of errors (bad frames) that have com in on the interface. This is a total of all the errors I will list below

520802 CRC

This incriments by 1 every time a packet comes in on the Interface that is corrupt or dammaged. These pactets are dropped after they are found to be bad

264039 frame

This incriments by 1 every time a packet comes in on the interface that does not appear to be aligned properly with the timing signal

594970 abort

This counter incriments by 1 every time the interface aborts trying to recieve a packet due to problems.



That is the end of the input errors
There is another indication of a line problem:

46 interface resets

I will past in Cisco's explanation as it is easier than typing it.

Number of times an interface has been completely reset. This can happen if packets queued for transmission were not sent within several seconds. On a serial line, this can be caused by a malfunctioning modem that is not supplying the transmit clock signal, or by a cable problem. If the system notices that the carrier detect line of a serial interface is up, but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an interface is looped back or shut down.


It should be noted that there are no carrier transitions. A carrier transition happens when the interface no longer sees the line available.



Summary:

I think you were correct to try replacing the cable, I would also recomend that you present this data to your provider and ask them to do line diags.


I hope you got something useful out of that.

[menny10]

thanks, Jay ,
I already change the utp cable, from the cisco to the switch, but the other cable v35, only the isp has a replace for it, and hope the inetrnet still fast, and wait to my isp, to read all my lines.
