Configuring High Availability VLANs Application Examples
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 5-9
Application Examples
This section contains the following HAVLAN application examples:
• “Example 1: Layer 2 Server Cluster” on page 5-9.
• “Example 2: Layer 3 Server Cluster” on page 5-11.
• “Example 3: Layer 3 Server Cluster with IP Multicast Address to Cluster (IGMP)” on page 5-13.
Example 1: Layer 2 Server Cluster
In the following example, the MAC address can be unicast or L2 multicast or IP multicast.
Switch connected to an L2 server cluster through 3 ports (1/3, 1/4, 1/5)
• A server cluster can be configured with a unique MAC address and a VLAN with a port list
• The traffic which ingresses on 1/1 or 1/2 destined to the server cluster MAC address and the VLAN is
forwarded to all the egress ports configured.(1/3,1/4,1/5).
• Here the ingress ports must be in the same VLAN as the server cluster VLAN and egress ports and
other traffic must be switched according to the normal switching logic.
Configuration Example
In this example, a packet can be an L2 or IP switched packet and Egress port can also be a linkagg port.
1 Create a server cluster that will become the HA VLAN by using the command server-cluster and
configure the mode. For example:
-> server-cluster 1 mode l2 admin-state enable
