VLAN interface can be created on a NIC whenever there is a need for the interface to subscribe to a separate broadcast domain (usually needed for high traffic data networks).
Additionally, multiple VLAN interfaces can be created on a single physical NIC, thereby allowing access to multiple networks at the same time. The VLANs act as virtual individual NICs, each belonging to a separate broadcast domain.
Adding VLAN interface
- In the HA Groups page (ElastiCenter > HA Groups), go to the actions pane and then click Tasks > Manage VLAN Interfaces.
- In the VLAN Interfaces page, go to the actions pane and then click Tasks > Add VLAN Interface.
- In the Add VLAN Interface dialog box, specify the VLAN tag (which must be a numeric value) and then select the parent NIC.
- Click OK.
Defining the VLAN Interface for the VSM
When you provision a VSM, in the networking details section of the Provision VSM Wizard, specify the VLAN interface you created (in the Interface field).
LAGG interface allows aggregation of multiple network interfaces into a single virtual LAGG interface, providing fault-tolerance and high-speed multi-link throughput. The aggregation supported by LAGG determines which ports are used for outgoing traffic and whether a specific port accepts incoming traffic.
Adding LAGG interface
- In the HA Groups page (ElastiCenter > HA Groups), go to the actions pane and then click Tasks > Manage LAGG Interfaces.
- In the LAGG Interfaces page, go to the actions pane and then click Tasks > Add LAGG Interface.
- In the Add LAGG Interface dialog box, specify the following details:
- LAGG ID: Unique name for the LAGG interface.
- Protocol Type: Select Failover to send traffic only through the active port. If the master port becomes unavailable, the next active port is used. The first interface added is the master port. Any interfaces added after that are used as failover devices. By default, received traffic is only accepted when received through the active port. If you select Load Balance, balances the outgoing traffic across the active ports and accepts incoming traffic from any active port.
- Click Next.
- From the list of available NICs, drag and drop the ones you want to assign to a LAGG.
- Click Add.
