During the switch-over, the redundant switch reboots itself and comes up
as the active one. A temporary dropping of all connections will occur
during the switch-over. The connections are re-established after the
switch-over process is complete.
Switching Module
Configuration
Database
Each switching module contains a configuration data base where the
switch configuration data is stored. In order that the redundant switching
module be ready to assume the role of the active switch, its configuration
database is updated from the active switch. This occurs in the following
situations:
When the switch is booted.
When the switch configuration is changed.
Not all of the configuration data is transferred from the active to the
redundant switch. The data that was not transferred must be updated
manually. The following table presents data which is transferred and data
which must be updated manually (see “Setting up Switch Module
Hardware Redundancy” on page 4-7).
