internet slow and isp replying me with this email ... what does it mean?

[amralrazzaz]

dear all 

i have internet problem and after checking with isp they replying me with below email ...i need to know which line is abnormal and i can know from it that packets drop and network slow?

Dear Sir,

Please be informed that, after investigation we see the path is stable physically as no logs has been detected till the site router

Also we see your current Traffic now exceed 4Mbps which cause the exists packet drop and latency.

Kindly check the below output from the site router.

thanks a lot sir ill try it and confirm 

is it important to change the nat from extend to standard in my case ?

what the effect if i change it to standard?

thanks alot

Hello,

a standard access list simply uses less resources (CPU/memory), that is the benefit. That said, your problem and bottleneck remains the 4MB Internet connection...

[amralrazzaz]

5 minute input rate 464000 bits/sec, 422 packets/sec

5 minute output rate 4554000 bits/sec, 420 packets/sec

i have internet connection 4MB speed , so the above output mean i exceed the limit?

i mean whats the value it should be to not exceed limit of 4 mb and drop packets?

464000 bits/sec, 422 packets/sec and 4554000 bits/sec, 420 packets/sec

whats the max number should be if my connection is 4 mb ?

it should be 4000000 bits/sec(just to understand) for in and out and more than this it will be slow connection and packets drop????

Hi amr,

That is correct. Max 4mbps line should be around 4000000bits/sec.
Means you have over the bandwidth, my best advise is upgrade the internet or implement qos to your network.

clear ip nat forced command will effect on voice configuration

or it will not effect at all on my network topology except the internet connection untill its reconfigured again 

also when i delete ip nat in

please check below output when i try delete source list 150

Router(config)#no access-list 150 permit ip any any
Router(config)#no ip nat inside source list 150 interface GigabitEthernet0/1 o$

Dynamic mapping in use, do you want to delete all entries? [no]: no  or i should press yes and what will happen then
%Error: Dynamic mapping in use, cannot remove

[amralrazzaz]

thanks alot 

its better to upgrade speed but just to know how to make qos on my network 

is there is any configurations?

thanks

regards

Hi,

You will need to implement QoS to your enviornment if your router cpu is ok.
To differentiate the higher priority ip range to access internet and lower priority ip range.
