Note:
Due to the difference in the amount of physical memory and session capacity between
different Alteon models, not all sessions can be synchronized. Session synchronization works
correctly if the same model Alteons are used in VRRP HA topologies.
Automate Session Mirroring
Session mirroring can be automated to synchronize sessions from master to backup at the
configured time and frequency. Time is specified as hour/minute/date/month/year, and frequency is
specified as daily, weekly, or monthly. Based on this, configuration mirroring is done at every
configured period.
For example, if the frequency is configured as weekly (w), mirroring is performed on the date it is
configured once a week. If frequency is configured as monthly (m), mirroring is done on the date it
is configured once a month.
