> # Enabling State Synchronization

> State synchronization is achieved when the SAE is required to communicate with the policy server over the COPS connection.

> Use the following configuration statement to configure state synchronization:

> `
> shared sae configuration driver pcmm {
>   disable-full-sync;
>   disable-pcmm-i03-policy;
>   session-recovery-retry-interval session-recovery-retry-interval;
> }
> `

> To enable state synchronization with policy servers:

> 1. From configuration mode, access the configuration statement that configures the PCMM device driver.
>    `
>    user@host# edit shared sae configuration driver pcmm
>    `
> 2. Specify whether state synchronization with the PCMM policy servers is disabled.
>    `
>    [edit shared sae configuration driver pcmm]
>    user@host# set disable-full-sync
>    `

>    When using other PCMM-compliant policy servers (instead of the JPS), we recommend setting this value to true.

> 3. Specify whether PCMM I03 policies are disabled when the SAE is deployed with pre-PCMM I03 CMTS devices.
>    `
>    [edit shared sae configuration driver pcmm]
>    user@host# set disable-pcmm-i03-policy
>    `

>    When there are pre-PCMM I03 CMTS devices in the network, you must set this value to true.

> 4. Specify the time interval between attempts by the SAE to restore service sessions that are still being recovered in the background when state synchronization completes with a state-data-incomplete error.
>    `
>    [edit shared sae configuration driver pcmm]
>    user@host# set session-recovery-retry-interval session-recovery-retry-interval
>    `

>    We recommend setting this value to 3600000 (1 hour) or longer.
