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:
For each subnet, add the required number of IPs as physical IPs to create the VLAN. The required number of IPs is equal to the number of nodes that are present. Do not add extra IPs.
Create the VLAN using the network vlan add command. The IPs that you added are automatically picked for VLAN creation.
Add a route for the newly created subnet, if required.
If you want to create another VLAN, repeat the above steps.
Note:
If the IPs are not added in the correct sequence, the network vlan add command may pick IPs which belong to different subnets.
For example:
