Support for multiple data subnets
Access Appliance now supports multiple data subnets. This is applicable to all the protocols that the Access Appliance supports. If you have different subnets, you can access the services of the Access Appliance cluster via those subnets. The protocol specific entities and features decide how the subnets are utilized by the individual protocol. Multiple subnets can be configured with or without multiple VLANs.
Note:
Data network isolation depends on the customer network configuration. The application configuration in Access Appliance does not restrict the customer from using the same network for multiple protocols.
If you have multiple subnets and you want to create multiple VLANs for each subnet, then Veritas recommends the following:
Create a VLAN using the network vlan add nic VLAN_ID command, which creates a new device called nic.VLAN_ID.
Add new virtual IP address belonging to the VLAN using the network ip addr add command.
Add a route for the newly created subnet, if required.
If you want to create another VLAN, repeat the above steps.
