About Interface Mapping Parent topic

Trend Micro recommends mapping the interfaces with physical interfaces before configuring or modifying your interface settings.
After rebooting IWSVA, the numbering for unused interfaces may change, however the occupied interfaces (for data, management, or HA) will not change.
Before dissolving a cluster, interfaces might be mapped as shown below:
Physical Interface A B C D
Relative Interface eth1 eth2 eth0 eth3
Purpose
D
(internal)
 H
D
(external)
 M
After dissolving a cluster, joining a cluster, or rebooting, the interface mapping might change as shown below:
Physical Interface A B C D
Relative Interface eth2 eth1 eth0 eth3
Purpose (internal) (unused)
D
(external)
