MPM-CW combines the signaling and management
functions of the MPM and FCSM modules in a pure ATM
switching environment

ATM core switching
functionality

Redundant MPMs
Redundant MPMs





provides added security in the event of an MPM
problem, which ensures NO single point of failure
the secondary MPM mirrors ALL configuration and
software updates of the primary MPM
either MPM may initialize as the primary or secondary
on switchover, the IP address of the switch remains the
same; however the MAC address changes
the address tables must be updated to reflect this
change

therefore, the switch performs a warm reboot and the new
MPM’s addresses are resolved
