Overview
This chapter provides an overview of the Connectivity Management Processor (CMP).
This chapter includes the following sections:
•
Information About CMP, page 1-1
Information About CMP
The CMP is a separate processor on the Cisco Nexus 7000 Series Supervisor 1 module that is in addition to the main control processor (CP). The CMP provides a second network interface to the switch 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.
Note The CMP is available only on the Supervisor 1 modules, not on the Supervisor 2 nor Supervisor 2E modules.
•
•
•
•
•
Each CMP contains its own RAM, bootflash, and front panel management Ethernet port. The CMP eliminates the need for a separate permanent terminal server attached to your supervisor module. You connect to the CMP through its CMP-management Ethernet (CMP-MGMT ETH) port with a Secure
Shell (SSH) or Telnet session to monitor or reboot the supervisor module. If the associated supervisor module CP is operational, you can also connect to the CMP from the CP to reboot the CMP.
Each CMP remains operational even if its supervisor module is in standby mode or the switch is down because of issues such as over-temperature alarms. Each CMP gets power from an auxiliary power bus in the switch that remains operational so long as you have at least one power cable attached to the switch.
The CMP provides the following functions:
• Communicates with the Supervisor 1 module and I/O modules even if Cisco NX-OS switch 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.

CMP Access
When the CP and CMP are both operational, you can log into the CMP through the CP using your
NX-OS configured username and password or the admin username and password. If the CP is configured with RADIUS or TACACS, then your authentication is also handled by RADIUS or TACACS. If the CP is operational, the CMP accepts logins from users with network-admin privileges. The CMPs use the same authentication mechanism to configure the CP (that is, RADIUS, TACACS, or local). The CP automatically synchronizes the admin password with the active and standby CMP so that you can use the “admin” username and password when a CP is not operational. For more information on user accounts and user roles, see the Cisco Nexus 7000 Series NX-OS Security Configuration Guide, Release
5.x.
Note The active CP also synchronizes all NX-OS configured usernames and passwords with the standby CP so that you can use your NX-OS configured username whenever a CP is operational.
If you are connecting to the CMP through Cisco NX-OS, you must be in the default virtual switch context (VDC). For more information on VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual Device
Context Configuration Guide, Release 5.x.
The SSH server is enabled by default on the CMP. We recommend that you do not disable the SSH server on the CMP, but if required, you can disable the SSH server and enable the Telnet server.

Chapter 1 Overview
Information About CMP
High Availability
A fully redundant switch contains two supervisor modules. If these modules are Supervisor 1 modules, they each have a CMP. Although only one supervisor module is active at any one time, the CMP software in each supervisor module is always active. For a high-availability configuration, you should connect four Ethernet cables to these supervisor modules—one for each mgmt 0 interface and one for each cmp-mgmt interface. You should also configure three IP addresses—one for each cmp-mgmt interface and one that is shared between the active and standby supervisor mgmt 0 interfaces.
Note Supervisor module switchovers do not reload the CMPs.
A supervisor module is fully operational only if both the CP and its CMP are operational.
Note A CMP failure does not cause a supervisor module switchover.

This chapter explains how to connect and configure the Connectivity Management Processor (CMP) on a Cisco Nexus 7000 Series switch. It also explains how to update the software image for the CMP.
This chapter includes the following sections:
Connecting to the CMP MGMT Ethernet Port, page 2-1
Verifying the CMP Configuration, page 2-29
Upgrading the CMP Image, page 2-30
Default Settings for CMP Parameters, page 2-31
Connecting to the CMP MGMT Ethernet Port
To connect the CMP to the network, follow these steps for each installed supervisor:
Step 1
Step 2
Step 3
Connect a modular, RJ-45, UTP cable to the CMP MGMT ETH port on the Supervisor 1 module.
Route the cable through the central slot in the cable management system on the Cisco Nexus 7000 Series chassis.
Connect the other end of the cable to the networking device.
You configure the cmp-mgmt interface during the initial setup script on the CP when you first configure your switch. See the Cisco Nexus 7000 Series NX-OS Fundamentals Configuration Guide, Release 5.x for details on the setup script.
Caution To prevent an IP address conflict, do not connect the CMP MGMT port to the network until the initial configuration is complete. For more information on Ethernet connections and cable management, see the
Cisco Nexus 7000 Series Hardware Installation and Reference Guide.

Configuring the Cisco Discovery Protocol for the CMP
The Cisco Discovery Protocol (CDP) is a media- and protocol-independent protocol that runs on all
Cisco-manufactured equipment including routers, bridges, access and communication servers, and switches. You can use CDP to discover and view information about all the Cisco devices that are directly attached to the switch.
CDP gathers protocol addresses of neighboring devices and discovers the platform of those devices.
Each switch that you configure for CDP sends periodic advertisements to a multicast address. The advertisements also contain hold-time information, which indicates the length of time that a receiving device should hold CDP information before removing it. You can configure the advertisement or refresh timer and the hold timer.

Saving Console Output on the CMP
•
•
•
•
•
Beginning with Cisco NX-OS Release 5.0, you can log console output on the CMP to help you troubleshoot problems that you might encounter when reloading the CP on your Cisco Nexus 7000
Series switch. To manage the log file on the CMP, you can specify the size of the file, display its logs, archive the file on the CP log flash drive, and clear logs from the file. The changes that you make to manage the logging of console output are recorded in the running configuration. To activate these changes for future sessions, you must copy the running configuration to the startup configuration after making the changes.
This section includes the following topics:
Logging Console Output on the CMP, page 2-12
Specifying the Size of the Logging File, page 2-13
Showing Logged Output, page 2-14
Archiving a Log File, page 2-14
Clearing the Log File, page 2-15
Logging Console Output on the CMP
When you enable the logging of console output on the CMP, you can either use the default file size
(50 kilobytes [KB]) for the logs or specify another file size between 10 KB and 100 KB. You can enable or disable this logging function while working in the CP or in the CMP.
Note When the log file fills with logs, the system creates another file and begins filling it with logs.
BEFORE YOU BEGIN
If you are operating in an attach CMP or detach CMP mode, your configuration change to enable or disable the logging is recorded in the running configuration but the switch does not change this function for the current session.

(Optional) Saves this configuration change.
Example: switch(config)# copy running-config startup-config
Note To disable the logging of console output, use the no capture cp console command. When you use this command on the CP, it applies the CMP configuration to both the active and standby supervisor modules.
Specifying the Size of the Logging File
You can specify the size of the console output logging file separately from enabling or disabling the logging function. You can do this action while working in the CP or in the CMP.
BEFORE YOU BEGIN
If you are configuring the CMP from the CP, you must not be in an attach CMP mode.
If you are configuring the CMP from the CMP, you must not be in a monitor CP mode.
Note If you are operating in an attach CMP or detach CMP mode, your configuration change to enable or disable the logging is recorded in the running configuration but the switch does not change this function for the current session.

Logging CMP Messages
You can save up to 256 CMP messages in a log file, and you can specify a severity threshold for the messages saved. When the file has 256 messages, the CMP automatically removes the oldest message whenever it saves a new message.
Table 2-3 describes the message levels and types of messages that the
CMP saves. When you specify a severity level, the CMP saves messages for that level and all levels below it in the log file.

Configuring CMPs on a Dual Supervisor System
The CMP runs in active mode on both supervisor modules, even when only one supervisor module is active, so you must configure each CMP individually. You can configure the unique IP address for each
CMP from the active CP by using Cisco NX-OS commands through either the CLI or scripts. To perform all other CMP configuration functions, connect directly to the CMP that you are configuring to perform those functions.

Upgrading the CMP Image
Upgrading the CMP Image
You can upgrade the CMP image, which is part of the Cisco NX-OS system image and contains a subset of commands to support the CMP features.
Note The CMP image is independent of the CP image, so the version of the CMP image might not match the version of the CP image. To make sure that the CMP is running the latest compatible image, use the
install all command from the Cisco NX-OS CLI on the CP.
To upgrade the Cisco NX-OS kickstart image, system image, and CMP image at the same time, use the
install all command from the Cisco NX-OS CLI on the CP. This command automatically upgrades the software on both CMPs. After the software is upgraded, you must manually reload the CMP on each supervisor. For more information on software images, see the Cisco Nexus 7000 Series NX-OS Software
Upgrade and Downgrade Guide, Release 5.x.
Use the following procedure if you want to update only the CMP image.
BEFORE YOU BEGIN
Ensure that you are in the default VDC (or use the switchback command).
