IBM SC30-3681-08 manual Closed User Group Null Encapsulation

Using the X.25 Network Interface

Con®gure CUG using the add address. The CUG(s) de®ned must be the same for each protocol de®ned at the same address.

If the CUG is de®ned at the add protocol level, The CUG(s) must be the same for all peers. (This method is more restrictive).

Con®gure CUG at the interface level. This insures all peers have the same CUG values. (This method is the most restrictive)

Any of the above methods may be used as long as any incoming call CUG de®nition must be valid for all protocols sharing that circuit. Valid means that the CUG was de®ned for the speci®c address or was defaulted to use either the protocol or interface circuit de®nition.
