This carries whether the tunnel referenced by this trap is static(1) or dynamic(2). This distinction matters to whoever's handling the alert because a dynamic tunnel's control plane may attempt to automatically re-signal around the problem, while a static tunnel will just sit down until someone manually reconfigures it — so the appropriate response to the same trap differs depending on this value. A trap about a failed tunnel might report dynamic(2), telling the on-call engineer the device may already be attempting automatic recovery before any manual action is needed.
