Understanding Interface Naming Conventions for MPC2

 

MPC2 facilitates configuration compatibility and enables you to replace an MX DPC with an MPC1 or MPC2 without requiring configuration change. The chassis daemon process (chassisd) creates physical interfaces for the tunnels only if it finds an associated tunnel bandwidth configuration.

The naming convention for virtual tunnels, for example is as follows:

vt-mpc-slot/pic-slot/port-number.

On MPC2, the pic-slot could be of the range 0 through 3. The logical pic slot 0 and slot 1 are associated with PFE 0 and logical MIC slot 2 and slot 3 are associated with PFE 1.Table 1 summarizes the MIC/PIC mapping for MPC2E, MPC2E-Q, and MPC2E-EQ.
