Nimble OS 2.0 Part 10 – IP Address Zone Settings

Blog Post created by Klaus Kupfer Employee on May 19, 2014

This post wraps up our ten-part series on the new features in Nimble OS 2.0, and so we complete the circle by going back to the first post, where Nick Dyer explored the new networking features.

This time, we’ll examine the new IP Address Zone settings in the Networking Screen.

The default setting is Single which is ok if you use only one switch or if you have a large stacking pipe.

If in doubt, please contact Support or your local SE.

However, if you have a lower bandwith connection, leaving the default setting could lead to unnecessary traffic over the ISL.

To avoid this, there are two settings you can choose (Bisect or Even/Odd), but they require some planning beforehand:

A: Bisect - Lower half of the subnet range in one group, upper half in another, eg. 192.168.50.0/24 has

Lower half: 192.168.50.1 – 192.168.50.127

Upper half: 192.168.50.128 – 192.168.50.254

All Host and Data IPs in the lower half of the subnet should be configured on one switch while those in the upper half should be configured on another switch.

 

B: Even/Odd – Grouped by the last bit, e.g. 192.168.50.2 is even, 192.168.50.3 is odd

Keeping an eye on these settings ensures that your environment runs at the maximum speed.

This ends our series of blogs about the new features in NOS 2.0, just in time for the amazing new stuff coming out in NOS 2.1. We’ll keep you posted.
