Hello all.
I have a router in my internet access but this share the connection with other routers.
My question about BW is that if I want to configure QOS and shaping,,, what BW I need to use?
I don't understand where can I found BW used in a interface.
Thanks for your help gurus!!!

Hi,
On any interface you will see the usage over the last 5 minutes by default
Example on my switch (Routers are the same)
show int fas 1/0/48
!
FastEthernet1/0/48 is up, line protocol is up (connected)
Hardware is Fast Ethernet, address is 0017.9562.6534 (bia 0017.9562.6534)

Hi,
This will show the input/output usage for the last 5 mins
You can tweek this down to the last 30 seconds

Albert,
You are welcome
Yes you are correct with your figures
You can also look at the loading figures on the interface but
you need to use your maths
FastEthernet1/0/48 is up, line protocol is up (connected)
Hardware is Fast Ethernet, address is 0017.9562.6534 (bia 0017.9562.6534)
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 206/255, rxload 67/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec).......................
So TX load is 206/255 = 206 X 100/255 = 80. 78 %
RX load is 67/255 = 67 x 100/255 = 26.27 %

And this is the current interface BW? With this number can I calculate the average of the interface BW?
4kbps is the current BW?

Thank you for your answer.
And if it's a fasthernet link and the output tell there are 5Mbps, the link is 5/100=1/20=5% of the link used?
Tell me this last issue and I will understand all!!!
Thank you!
Albert.
