Bandwidth Percent

kafifi13

Guys,

What show command will help me find what the Bandwidth percent was set on an existing production network? I'm currently trying to find something under the show interface command. Bandwidth is set to 3072 k but i'm trying to find out what Percentage of that is to be utilized since EIGRP by default only uses half.

well i don't know of a command in the ios itself but you could use netflow and a netflow collector to answer your question.

nbar would only give you 5 minute samples.....

Not sure if this is what you are looking for, but if the bandwidth-percent is changed it will show on the config. It won't show if its set to the default.

I think you kinda answered your own questions.

Like you said - EIGRP uses half the bandwidth by default. If you don't see the "Router(config-if)# ip bandwidth-percent eigrp percent" under the interface in question I would think you could assume that the default 50% would be used.

"The following example allows EIGRP to use up to 75 percent (42 kbps) of a 56-kbps serial link in autonomous system 1:

interface serial 0

bandwidth 56

ip bandwidth-percent eigrp 1 75"
