Protection switching for LCAS, SW-LCAS, and non-LCAS VCAT circuits might exceed 60ms. Traffic
Note
loss for VT VCAT circuits is approximately two times more than an STS VCAT circuit. You can
minimize traffic loss by reducing path differential delay.

destination can have only two members.
CE-100T-8 cards—You can add or delete members to an LCAS VCAT circuit without affecting
service. Before deleting a member of an LCAS VCAT circuit, Cisco recommends that you put the
member in the OOS-MA,OOG service state. If you create non-LCAS VCAT circuits, adding and
deleting members to the circuit is possible, but service-affecting.
CE-1000-4 cards—You can add or delete SW-LCAS VCAT members, although it might affect
service. Before deleting a member, Cisco recommends that you put the member in the
OOS-MA,OOG service state. If you create non-LCAS VCAT circuits, adding and deleting members
to the circuit is possible, but service-affecting.
FC_MR-4 (enhanced mode) card—You can add or delete SW-LCAS VCAT members, although it
might affect service. Before deleting a member, Cisco recommends that you put the member in the
OOS-MA,OOG service state. You cannot add or delete members from non-LCAS VCAT circuits on
FC_MR-4 cards.
