configuing bandwidth on Cisco interface

I would like to know in case I want an interface to be slower than it really is, whether configuring bandwidth with lower rate can be a solution.
for instance a Gigabits interface, configured with bandwidth 64000 bits
would this really slow down the interface data flow by making the pipe smaller?
Thanks

Did you thought about QoS over that interface? Thats how you can control the bandwith over one Interface.

for example:

No. The bandwidth parameter is only used in advertising link speed. i.e. Spanning tree, OSPF, EIGRP will use it to determine cost.  But it has no effect on the actual speed of traffic on the interface.

If you want the traffic to move slower, rate limiting is how you would do it.

if your Gig is rj45 then you can set "speed 10" for lower BW like in Cisco1921.

else you can apply service policy for yourdesired BW.

If you want I can help you with service policy configs. but tell me the router model.

Ok...

for a 100MBps interface
speed 10
will make the interface transmits and receive data at the reate of 10MBps.

Bandwidth, is just to change the cost od the port.

Correct?
