This read-only enumerated value reports whether the protection group is revertive(1), the default, meaning traffic automatically switches back to the working path once it recovers, or noRevertive(2), meaning it stays on the protection path until manually switched back. An admin checks this to know whether a fixed working path fault will self-heal traffic placement once repaired or requires manual intervention. For example, h3cTeTunnelPsRevertiveMode=noRevertive(2) means the admin must manually switch traffic back to the working tunnel after a fault is fixed rather than it happening automatically.
