Cisco 3600 NM-1E

Is it pure 10Mb?

The Ethernet card supposed to enable maximum 10Mb bandwidth. Some technician explain that cause the Ethernet protocol character the efficiency is only 30% from 10Mb in standard conditions and in laboratory conditions with clean connection the efficiency was 70%.

Cause of that the maximum efficiency is 3Mb and even less 2.5Mb. He also said that the stricts don't use lines over 2Mb to work in Ethernet protocol.

Is it true?

What is the real maximum efficiency of the Ethernet card NM-xE?

Re: Cisco 3600 NM-1E

By default, 75% of the interface bandwidth can be used for fancy queueing. If this percentage needs to be changed, the max reserved bandwidth command can be used to specify the amount of bandwidth being allocated to fancy queueing. The formula for calculating the Available Bandwidth is

Available Bandwidth = (max reserved bandwidth * interface bandwidth) - (sum of priority classes)

The above formula will be used only if the policy map is configured and also the policy map should be appiled to the corresponding interfaces. If the policy map is not configured then the formula for calculating the Available bandwidth is

Available Bandwidth = (max reserved bandwidth * interface bandwidth).
