Chapter 22 Configuring Redundancy
When you enable high-availability redundancy, every configuration command executed on the
designated MSFC is sent to the nondesignated MSFC. Also, the running configuration synchronization
is updated when you enter the copy source running-config command on the designated MSFC.
These sections provide information about MSFC configuration synchronization:
•
•
Configuration Synchronization States
The two states for the configuration synchronization are as follows:
•
•
When you enable the Config Sync RuntimeStatus, the following occurs:
•
•
•
When the Config Sync RuntimeStatus is in disabled mode, the following occurs:

Various configuration and operation cases are covered in the
Configuration Examples" section on page
alt Keyword Usage
When you enable the Config Sync RuntimeStatus, the configuration mode on the nondesignated MSFC
is disabled; only the EXEC mode is still available. Configuration of both MSFCs is made through the
console or a Telnet session on the designated MSFC.
To configure both MSFCs from a single console, enter the alt keyword to specify an alternate
configuration. When specifying the alternate configuration, the configuration specified before the alt
keyword relates to the MSFC on the supervisor engine in slot 1 of the switch; the configuration specified
after the alt keyword relates to the MSFC on the supervisor engine in slot 2.
The alt keyword is required when Config Sync AdminStatus is enabled.
