Configuring client information backup
Before performing this task, establish an IACTP tunnel (see "Configuring WLAN roaming") and
configure AC backup (see Configuring 1+1 AC backup ) on the two ACs.
By default, client information backup is disabled. H3C recommends that you enable client information
backup after the configuration of 1+1 AC backup and IACTP tunnel. 1+1 AC backup takes effect only if
client information backup is enabled on both ACs.
