This read-only TruthValue indicates whether sequencing is enabled for a VPDN user session. Administrators use it to confirm whether packet sequence numbering (which helps detect and potentially reorder out-of-order packets) is active for a given session, which affects how to interpret related counters like cvpdnSessionOutOfOrderPackets. For example, if a session shows sequencing disabled, the admin would know that any packet-ordering issues on that session aren't being tracked or corrected by the sequencing mechanism at all.
