Description
Type a name for such profile.
Choose one of the LAN profiles that such function will be
applied to.
Assign an IP address as a virtual IP.
It means Virtual Host ID. Type a number as VHID for such
function. VHID is used for Backup router to identify which
Master will be backed up.
LAN profiles configured for HA application can run
independently and will not interfere with each other.
Therefore, LAN1 (Backup) of router A can be the backup of
LAN1 (Master) of router B; LAN2 (Backup) of router B can
the backup of LAN2 of router A(Master).
Each HA LAN profile (configured under the same router) must
be specified a role as Master or Backup.
