11.17 11.17.4 VCAT Circuit Size
Use the Members tab in the Edit Circuit window to add or delete members from a VCAT circuit. The
capability to add or delete members depends on the card and whether the VCAT circuit is LCAS,
SW-LCAS, or non-LCAS.
• 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.
• FC_MR-4 (line mode) card—All VCAT circuits using FC_MR-4 (line mode) cards have a fixed
number of members; you cannot add or delete members.
• ML-Series cards—All VCAT circuits using ML-Series cards have a fixed number of members; you
cannot add or delete members.
Table 11-17 summarizes the VCAT capabilities for each card.

1. A VCAT circuit with a CE-Series card as a source or destination and an ML-Series card as a source or
destination can have only two members.
