In the illustration below, the two-site network has been expanded to four sites. Site 1 now has three DLCIs configured on Port 1, and Site 2 has two DLCIs configured on Port 1. Notice that Site 1 and Site 2 both have a DLCI of 100. This is acceptable because DLCI numbers do not need to be unique across the network.
At Site 3, the FRAD is not attached to Port 1 on the Passport 4400 base module; it is attached to Port 1 of exp1, which is the High-speed Data Module (HDM) in Slot 2. At Site 4, the FRAD is attached to Port 2 of exp1 (the HDM). Notice that the IfIndexes for the frame relay DCE service reflect these port locations.

Note: For Passport 4430, 4450, and 4455, the Logical Interface Module (LIM) name for the base module is always limA. The WAN and Expansion modules are numbered lim1 through lim4. For the Passport 4460, the LIM name for the base module is always base, Expansion modules are named exp1, exp2, and the PCMCIA module is named pcmciaExp. |
This section discusses the switch maps for sites 1 through 4 as illustrated in the above figure.
