This is a question that never got answered on the cisco learning network fourm that I am curious about....I never could find the answer.
If you change the default EIGRP bandwidth from 50% to something else with the ip bandwidth-percent EIGRP AS %% command, where can you look to see this change reflected?
in this link you can found more information
You can indirectly check this by having a close analysis on how EIGRP paces its packet.
The "sh ip eigrp interface" should give you a column indicating the pacing time in millisecs.
Each time a data packet is queued, EIGRP determines how long to wait before sending the packet based on the formula
(8 * 100 * packet size in bytes) / (bandwidth in kbps * bandwidth percentage)
This does have an effect on the protocols behaviour on the links !
Hope that helped !
Do you mean other than doing a "sh run" because if you modify the eigrp bandwidth on an interface it will be reflected in the running config.
