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:

# vconfig add eth2 10

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.

# vconfig rem eth2.10

VCS neither creates nor removes trunk interfaces. The administrator should set up the trunking as per the operating system vendor's documentation rather than using vconfig directly.
