Understanding Interface Naming Conventions for MPC1

 

MPC1 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 MPC1, the PIC slot could be 0 or 1. Both the PIC slots are associated with the Packet Forwarding Engine PFE 0. Table 1 summarizes the MIC/PIC mapping for MPC1E and MPC1EQ.
