is blocked. This is achieved using linear protection for CC defects, and by blocking the ingress
data path for CV defects.
NOTE: 7210 SAS-R6 supports only BFD based CC mode. BFD based CC-CV mode is not
supported in current release.
Note that when an LSP with CV is first configured, the LSP will be held in the CV defect state for
3.5 seconds after the first valid CV packet is received.
