Question about router screen capture?

[ScottFern]

Ok, I had an analysis done on our frame relay line here at work to see if we were maxing out the bandwidth. The NOC told me we were indeed at our limits but how do I decipher that from this screenshot he took?

Thanks!

He said that the load 18/255 was high and once it reaches 30/255 we would start to drop packets?

load is a value out of 255 of the bandwidth configured on the interface.

From the serial port
MTU 1500 bytes, BW 56 Kbit, DLY 20000 usec, rely 255/255, load 18/255

What's important is the load on the serial port, not necessarily the sub interface.

You guy's aren't using anywhere near the capacity of your link. The statement about dropping packets is also so far from the truth this noc monkey should be fired for incompetence. Also if that really is a 56k circuit, that is incredibly, painfully slow.

 

[ScottFern]

Yes, its a 56k frame relay line. Can you help me understand where it shows how slow it is?

 

[spidey07]

I just did. The load statement.

There's also this:
5 minute input rate 11000 bits/sec, 7 packets/sec
5 minute output rate 4000 bits/sec, 6 packets/sec

That is your input and output rate. 11 kbit in, 4 kbit out. Keep in mind that these cournters are a rolling 5 minute average so the counters should be cleared, then a large file transfer started, then record the output of show interface. Show frame-relay map is also a good command to see what the frame switch set your CIR to.

 

[ScottFern]

See now I am stuck in this whole mess......My boss just called me because I sent this to him in an email and he said that this proves nothing and he wants to wait until after we switch Circuit providers (basically switching to a new circuit card) and then run the test again. But when I got off the phone with the NOC at EDS he told me that our circuit was definitely maxed. WTF gives?

Thanks for the explanation!

 

[spidey07]

Not only is that noc clueless. So is your boss.

So this frame relay connection is definitely extremely slow and most likely the cause of our continued slow responses for our software that connects over this frame line?

 

[spidey07]

It's barely faster than a modem.

Absolutely the cause of your slow response. Changing to another 56k circuit will yield absolutely no improvement.

 

[ScottFern]

Right thats the point I am trying to get through to my boss. I think he is simply denying the idea that it is too slow because its an extra cost each month.
