Switch function Target Port Settings
1. Untagged cannot be used in a VF NIC configuration where guest OSs are Red
Hat Enterprise Linux 6.7/7.1/7.2.
Attention
• Logical NICs do not support advanced communication control functions
(for example, IGMP snooping, access lists, and QoS). Use communication
control functions of external switch modules. To control communications
between LPARs on the same LPAR manager, use the VLAN function of a
logical NIC or the Inter-LPAR communication packet filtering.
• Communication with external networks using VLANs Because IEEE802.1Q
tagged packets pass through the external physical switches, it is
necessary to set the VLAN ID used by the virtual network corresponding
to the shared physical NIC to physical switch port at the tagged port.
• Priority control in the IEEE802.1P format Priority control in the
IEEE802.1P format is not supported.
• When using VLAN functions and N+M cold standby at the same time,
attentions are as follows.
