Interface X
backup interface X
backup load [number] [number]

In the "backup load" command, the first number determines when the backup link will active. The second number is used to determine at what load percentage to deactive the backup link.

My question, is the second number based on the total combine load of the primary and secondary link or just based off of the primary link only?

Example, if the command was "backup load 70 10", would the backup link deactivite

A.) When the the load on the primary goes below 10 percent?
 
  or

B.) when the combine load on the primary and backup goes below 10 percent?

Hi iamuser,

Here is a link that will explain you the backup load command.

http://www.cisco.com/en/US/products/sw/iosswrel/ps1828/products_command_reference_chapter09186a00800ca527.html

This paragraph is from webpage. It explains the command very clearly.

"The following example sets the traffic load threshold to 60 percent of the primary line serial 0. When that load is exceeded, the secondary line is activated, and will not be deactivated until the combined load is less than 5 percent of the primary bandwidth.

interface serial 0
backup load 60 5
backup interface serial 1"

Cheers!

Now I'm really confused, NITADMIN's post (and cisco link) states

"The following example sets the traffic load threshold to 60 percent of the primary line serial 0. When that load is exceeded, the secondary line is activated, and will not be deactivated until the combined load is less than 5 percent of the primary bandwidth."

but BJharris says primary so which one is it really? Is Cisco wrong or is BJharris wrong?

iamuser,

I gave you a link to cisco webpage. This is Cisco's explanation of the command and how it works.
I didn't make it up. I don't know what BJHarris got his information from.

Cheers,
NITADMIN

I apologize.  I misread the description of the command.  I missed the 'combined load'.  nitadmin is correct.
