The IP/NIC and IPMultiNIC/MultiNICA agents support 802.1Q trunking.
The underlying utility to manage 802.1Q trunk interfaces is vconfig. For example, you can create a trunk interface on the physical interface:
This creates a trunk interface called eth2.10 in the default configuration. In this case, the physical NIC eth2 must be connected to a trunk port on the switch. You can now use eth2.10 like a regular physical NIC in a NIC, IP, and MultiNICA resource configuration. You can remove it with the following command.
VCS does not create nor remove trunk interfaces. The administrator should set up the trunking as per the operating system vendor's documentation rather than using vconfig directly.
