7.86 Hold-Off Time (ms) (LCAS)

Description
The Hold-Off Time (ms)(LCAS) parameter is also called HO Procedure Timer Duration. It
specifies HO Procedure Timer Duration of the LCAS protocol. If the LCAS coexists with
another network-level protection scheme (for example, MSP or SNCP), you can set this
parameter to postpone the LCAS switching.
Impact on the System
The LCAS switching tiime is affected.
For example, if both the MSP and the LCAS are available in a network, set the LCAS hold off
time to 2000 ms. If the network fails, only the MSP switching occurs, but the LCAS switching
does not occur.
