Usage Guidelines

Usage Scenario

In AC backup scenarios, a backup AC IP address is configured so that APs can establish CAPWAP tunnels to the backup AC if they fail to establish CAPWAP tunnels to the primary AC.

Precautions

The configurations of primary-access and backup-access take effect only if both the commands are run to configure different IP addresses.
primary-access and backup-access cannot be configured with priority or protect-ac.
It is not recommended that primary-access and backup-access be configured with ac protect protect-ac or ac protect priority.
The configuration takes effect only after the AP is restarted.
The IP addresses specified by primary-access and backup-access must be configured the same as CAPWAP source IP addresses. If the CAPWAP source addresses have been translated using NAT, set the primary-access and backup-access IP addresses to the translated addresses.

Example

# Set the backup AC IP address to 10.33.12.78.
