Appendix A Command Reference
spr wrap {immediate | delayed}
Use this command to set the Cisco proprietary RPR wrap mode to either wrap traffic the instant it detects
a link state change or to wrap traffic after the carrier delay, which gives the SONET protection time to
register the defect and declare the link down.

circuits, such as subnetwork connection protection (SNCP) or multiplex section-shared protection ring
(MS-SPRing).
