FPC Numbering for Interfaces in TXP-Mixed-LCC-3D Configuration


A routing matrix with the TXP-Mixed-LCC-3D configuration supports the following combinations of T1600 and T4000 routers:

  • Six T1600 routers and one T4000 router

  • Four T1600 routers and two T4000 routers

  • Two T1600 routers and three T4000 routers

In the mixed mode of operation, one T4000 line-card chassis (LCC) can be placed instead of two T1600 LCCs. The T1600 routers are assigned numbers from 0 through 7, depending on the chassis ID setting. The T4000 routers are assigned the even numbers 0, 2, 4, and 6.

The FPC numbering scheme for the TXP-Mixed-LCC-3D configuration remains the same as that used for the TXP-T1600-3D and TXP-T4000-3D configurations. For more details see, FPC Numbering for Interfaces in TXP-T1600-3D Configuration and FPC Numbering for Interfaces in TXP-T4000-3D Configuration.
