Strata Cloud Manager

1. Log in to Strata Cloud Manager.
2. Select ConfigurationNGFW and Prisma Access and in the Overview, select the branch folder for which you want to create your SD-WAN Link Management profiles.

   To make the Error Correction profile available to all SD-WAN firewalls regardless of folder association, select All Firewalls.
3. Create an Error Correction profile.

   SD-WAN supports Forward Error Correction (FEC) to correct certain data transmission errors that occur over noisy communication lines to improve data reliability without requiring retransmission or Packet Duplication to duplicate application sessions from one tunnel to another.

   1. Select Network PoliciesSD-WAN PolicyProfilesError Correction.

      To make the Error Correction profile available to all SD-WAN firewalls regardless of folder association, select All Firewalls.
   2. Add Profile.
   3. Enter a descriptive Name.
   4. Specify the Activation Threshold (Packet Loss %) to set the packet loss percentage that must be exceeded before error correction is activated.
   5. Select the error correction Mode.

      Only a single error correction Mode can be selected for an Error Correction profile.
   6. (Forward Error Correction only) Select the Packet Loss Correction Ratio to specify the ratio of parity bits to data packets.

      The higher the ratio of parity bits to data packets that the sending firewall sends, the higher the probability that the receiving firewall can repair packet loss. However, a higher ratio requires more redundancy and therefore more bandwidth overhead, which is a tradeoff for achieving error correction. The parity ratio applies to the receiving firewall’s outgoing traffic.

      Also specify the Recovery Duration (ms) to set the maximum number of milliseconds that the receiving firewall can spend performing packet recovery on last data packets using the parity packets it received.
   7. Save.
