Point to Point Speed issue 1

[TCChenDH]

I have setup a Point to Point with two Cisco 2610's with T1DSU WIC's. Everything is up and functioning, however the speed is not what I was expecting\promised. When I call the P2P provider they say "the pipe is clean". I have read many posts and seem to think my config on the routers are correct. What can I do to test my speeds and verify my config is optimal? and how can I test "the pipe". Thanks for the help.

 

[KiscoKid]

For a quick and dirty test, you could try opening multiple telnet windows to one of the 2610 routers.

Then from each terminal window, run an extended ping (such as I've pasted below from one of my live devices):

WB-CERGY-RO01#ping
Protocol [ip]:
Target IP address: 10.10.10.11
Repeat count [5]: 100000
Datagram size [100]: 1500
Timeout in seconds [2]:
Extended commands [n]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 100000, 1500-byte ICMP Echos to 10.69.5.1, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


Do this on each terminal window, pinging the remote 2600 each time. Leave one terminal window free and monitor the T1 utilisation using the 'show interface' command (tip: set the load-interval on the T1 interface to 30 seconds using the "load-interval 30" command in interface configuration mode)

You have a fair amount of errors on your T1 interface. Also it shows you hit around 115/255 of your total utilsation which is a little low for a T1.

Try the experiment again but this time before you do, enter the "clear counters" command to reset your interface s0/0 stats to zero.

Also try opening more telnet windows and running more extended pings. It may be there weren't enough running to load the T1. You may need at least 6-7 windows or so to load it up to 100%.

 

[TCChenDH]

OK, I ran a few more telnet sessions and below is what i got. My question is .... What speed should I be getting? Is copying a 30MB file in 8 minutes normal or slow? This is my first point to point and not sure what to expect.

[robertjo24]

Do you have a PC/server on each LAN?
If so, a better test of your bandwidth would be to FTP large files between machines.
Clear the counters on both routers.
After the test, look at the counters on both serial interfaces.
If the counters on both serial interfaces show input errors, I would suspect a config issue with the P2P T1 provider.
If there are errors on only one side or the other, I would suspect the local loop.

 

[KiscoKid]

The things you need to be looking at are on the serial0/0 interface, specifically the following lines:

30 second input rate 1205000 bits/sec, 151 packets/sec
30 second output rate 1230000 bits/sec, 201 packets/sec

A maxed-out T1 will deliver 1536000 bits/sec, you are close to this as you averaging 80%. I would say 95% is more than acceptable for a perfectly-functioning T1.

I also see the T1 errors have ceased which is a good thing.

Can you load up the circuit some more - perhaps another FTP or more ping windows till you get close to around 95% of 1536000 bits/sec?

 

[TCChenDH]

OK here is my "show interface". Am I just assumming that my connectin should be better? Is this a good T1?

[helpdeskdan]

I wouldn't say it's that great if you are really maxing it out. Take another look at KiscoKid's post. At least you don't have any errors this time.

 

[S3M1N0L3]

No errors on the T1 but the Ethernet interface has errors over the same 12 minutes.

1058 input errors, 1058 CRC, 0 frame, 0 overrun, 0 ignored

If the slowness on the test was through the LAN segment, that could actually cause the issue.
