To mark this port as redundant and to set up the protocol use the following command SSH@lb-l config server backup ethernet 100e0. With this configuration one switch will be active while the other switch will be inactive not forwarding IP or Layer 2 traffic.

It is designed to save time and help in a crisis situation when reading through a chapter would take too long. The quick command guide assumes you have set up the SLB units in a manner consistent with the examples and network architectures detailed in this book however these commands should work in most other circumstances as well. The syntax and information are based on the software and hardware versions of the products at the time of writing and may vary depending on your version.
