Chapter 1 Configuring a Cluster of ASAs
Configuration Examples for ASA Clustering
There could be multiple EtherChannels configured in the network. The following diagram shows an
EtherChannel on the inside and one on the outside. An ASA is removed from the cluster if both primary
and secondary links in one EtherChannel fail. This prevents the ASA from receiving traffic from the
outside network when it has already lost connectivity to the inside network.
