The CMP provides a second network interface to the device for use even when the CP is not reachable. You can access the CMP to configure it and to perform system operations, such as taking over the CP console or restarting the CP. The CMP can reset all system components, including power supplies; it can also reset the host supervisor module to which it is attached, enabling a complete system restart.

The Connectivity Management Processor (CMP) available even if its supervisor module is in standby mode or the device is down because of issues such as over-temperature alarms. Each CMP gets power from an auxiliary power bus in the device that remains operational so long as you have at least one power cable attached to the device.

All these options are available through the Connectivity Management Processor (CMP) because it contains its own RAM, bootflash, and front panel management Ethernet port.

The Connectivity Management Processor (CMP) provides the following functions:

• Communicates with the supervisor module and I/O modules even if Cisco NX-OS device is not responding on the mgmt0 port.

• Maintains connectivity when you reboot the supervisor module.

• Monitors the supervisor module console port.

• Reboots the local supervisor module or the entire system.

• Takes over the supervisor module console port.

• Collects failure logs and watches bootup diagnostic messages.

Cisco recommends to have two supervisor Engines per chassis in an active/standby mode.

The Supervisor Engine 1 Module provides the following

  • Dual-core 1.66Ghz Intel Xeon processors with 4GB DRAM
  • 2MB NVRAM, 2GB internal boot disk, 2 external compact flash slots
  • 10/100/1000bps management port
  • Console and Auxiliary serial ports
  • USB file transfer port
  • Connectivity Management Processor (CMP) with separate 10/100/1000 Ethernet access that will support 802.1ae LinkSec encryption in the future.
  • Supervisory modules run in Active/Standby mode for continuous operation

The most interesting part of Supervisor Engine 1 for me is the Connectivity Management Processor (CMP) which is basically designed to support remote management and troubleshooting of the system. Since a lot of information is available about Supervisor Engine 1, in my next post I will try to highlight the importance of Connectivity Management Processor (CMP) in the Supervisor Engine 1.
