Deployment Scenarios
This section presents illustrative Active/Standby Bridge mode deployments, which cannot function using a
standard STP Bridge mode configuration.
VLAN Shared Interface Deployment
In this deployment, each individual member connects to pair of redundant switches via a VLAN trunk. All
Virtual Systems in a given member share the same VLAN trunk. The following figure illustrates example of
such a deployment with active, standby and backup members.
Figure 5-26 Active/Standby bridge mode - shared interfaces
When using the Active/Standby Bridge mode in the High Availability mode, ClusterXL directs traffic to
members according to administrator-defined priorities and status. In VSLS deployments, the system
distributes the traffic load amongst members according to your VSLS configuration.
Three Layer Hierarchical Model
A three layer hierarchical model is used in very large, high-traffic network environments. It contains a
mixture of components as described below:
1. A core network, comprised of high-speed backbone switches directs traffic to and from the Internet and
other external networks.
2. A distribution layer, comprised of routers, provides connectivity between the core and the access
layer.
3. An access layer, comprised of redundant LAN switches, forwards traffic to and from internal networks.
