Size values are all of the above plus 16, 32, & 64. If X. 25 wi ll be run ove r thi s port , do
not configure a size greater than 2048. I f 4096 is specified, additional X.25 and frame

Mapp ed DLCI Nu m b er

is the Data Link Connection Identifier, which links the logical port to a logical con-

nection on the physical frame relay port. It must match the DLCI configured on the

device at the other end of the local (rather than end-to-end) connection.

Make sure no more than one of any interface type (logical port, frame relay IP/IPX/LLC2 interface, or frame relay Bridge port) is assigned the same DLCI.Also make sure this DLCI is not configured as a Frame Relay Backup DLCI or as part of an intra-nodal frame relay PVC.

Blocked Po rt Flag

causes the logical port to be disabled (Y) or en able d (N) (only if the physical port is

also enabled) at node IPL. The port will remain in that state until this parameter is

changed or an on-line enable ([B], [B], [C] fro m the Ma i n Me nu ) or disabl e ([B], [B], [A]

from the Main Menu) is performed.
