Limitations

The following are the known limitations of the feature:

  • When the peer version is determined to be lower than the supported N-1 version, the association/pairing is allowed. However, functional aspect of the same isn't guaranteed.

    Caution

    Don't attempt to upgrade from incompatible versions. Contact your Cisco Account representative for the upgrade path and steps.

  • Few CLI commands may not be supported in N+1 version.

  • The SMF version must be compatible with the UPF version.

  • The hardware configuration must be similar in both Active and Standby UPFs.

  • SNMP traps are raised by the node on the latest version with respect to the StarOS version. For details, see the SNMP Traps section of this chapter.

  • From release 2022.01.2, RCM is checkpoint agnostic to enable support for future UPF releases. Currently RCM supports only N-1 compatibility.
