Application Examples Configuring High Availability VLANs
page 5-14 OmniSwitch AOS Release 7 Network Configuration Guide June 2013
Configuration Example
In this example, a packet is an L3 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 3 mode L3
2 Create a default VLAN for the HA VLAN ports with the vlan command as shown below:
-> vlan 12
3 Assign member ports to the new default VLAN with the vlan members untagged command as shown
below:
-> vlan 12 members port 1/3 untagged
-> vlan 12 members port 1/4 untagged
-> vlan 12 members port 1/5 untagged
4 Assign mac-address for the new server cluster by using the command server-cluster mac-address. For
example:
-> server-cluster 3 ip 10.135.33.12 mac-address static 01:00:11:22:33:44
5 If you want to assign a dynamic mac-address for the server cluster, enter the command as follows:
-> server-cluster 3 ip 10.135.33.12 mac-address dynamic
6 Enable the admin state of the IP multicast by using the ip multicast admin-state enable command. IP
multicast admin state should be enabled for the IGMP reports to be processed., else the cluster will be
operationally down.
-> ip multicast admin-state enable
-> server-cluster 3 igmp-mode enable
-> server-cluster 3 ip-multicast 225.0.0.23
When IGMP mode is enabled for the server cluster, all static ports will be reset in igmp mode.
Note. Optional. You can display the configuration of high availability VLANs with the show server-clus-
ter command. For example:
-> show server-cluster 3
Cluster Id : 3,
Cluster Name : -,
Cluster Mode : L3,
Cluster IP : 10.135.33.12,
Cluster Mac-Address : 01:00:11:22:33:44,
Cluster Mac Type : Static,
IGMP-Mode : Enabled,
Cluster Multicast IP : 225.0.0.23,
Administrative State : Enabled,
Operational State : Disabled,
Operational Flag : No IGMP members
