4-9 – Serial Redundancy – Bypass Scenario

Serial Redundancy in Mesh Topologies

Serial Redundancy can support mesh topology configurations. In the network diagram
described below, each of the NetEnforcer units should be able to handle two links
which requires it to have four network interfaces. The AC-1020 can be used in such a
configuration.
