Chapter: Setting up Remote Management

Setting Up Remote Management

This chapter describes how to set up remote management in your startup configuration for use in recovering an unreachable Cisco Nexus Cloud Services Platform and includes the following sections:

Information About Remote Management

You can add remote management to your redundant Cisco Nexus Cloud Services Platform startup configuration so that if one of the pair becomes unreachable, the other can automatically attempt to recover it.

If redundant Cisco Nexus Cloud Services Platforms cannot communicate with each other over the management and control interfaces, they can both become active simultaneously. This process is known as a split-brain conflict. A Cisco Nexus Cloud Services Platform cannot be rebooted from its peer switch using high availability.

If one Cisco Nexus Cloud Services Platform becomes unreachable, its peer becomes active if it is the standby. If you have configured remote management, the new active Cisco Nexus Cloud Services Platform can attempt to power cycle its unreachable peer switch through the mgmt0 port of its Cisco Integrated Management Controller (CIMC) interface if CIMC is reachable on the peer. The active Cisco Nexus Cloud Services Platform starts the reboot code immediately when the standby is lost. The standby Cisco Nexus Cloud Services Platform waits 60 seconds before starting the reboot code.

For more information about losing communication between redundant Cisco Nexus Cloud Services Platforms, see the Cisco Nexus 1000V High Availability and Redundancy Configuration Guide .

For more information about CIMC, see the Cisco Integrated Management Controller section.

Configuring Remote Management

You can set up remote management in the startup configuration to recover an unreachable Cisco Nexus Cloud Services Platform peer switch through the mgmt0 port of its CIMC software.

BEFORE YOU BEGIN

Before beginning this procedure, you must know or do the following:

  • You previously configured the Cisco Integrated Management Controller (CIMC) when installing the Cisco Nexus Cloud Services Platform. For more information, see the Cisco Nexus Cloud Services Platform Hardware Installation Guide .
  • Have the following information for the Cisco Nexus Cloud Services Platform:

– CIMC management port IP address

– CIMC administrator login and password

  • This procedure has steps for setting up remote management for both the primary and secondary Cisco Nexus Cloud Services Platform.
  • Log in to the active Cisco Nexus Cloud Services Platform in EXEC mode.

SUMMARY STEPS

1. configure terminal

2. nexus1010-system remote-mgmt primary ip ipaddr username username password password

3. nexus1010-system remote-mgmt secondary ip ipaddr username username password password

4. (Optional) show running-config

5. copy running-config startup-config

DETAILED STEPS

 

Command
Purpose

Step 1

configure terminal

 

Example:

switch# config terminal

switch(config)#

Enters global configuration mode.

Step 2

nexus1010-system remote-mgmt primary ip ipaddr username username password password

 

Example:

switch(config)# nexus1010-system remote-mgmt primary ip 172.23.231.51 username admin password *************

switch(config)#

Sets up remote management in the running configuration of the primary Cisco Nexus Cloud Services Platform. The arguments are as follows:

  • ipaddress — the IP address of the CIMC management port
  • username — the admin username for the CIMC management software
  • password — the admin password for the CIMC management software

Step 3

nexus1010-system remote-mgmt secondary ip ipaddr username username password password

 

Example:

switch(config)# nexus1010-system remote-mgmt secondary ip 172.23.231.52 username admin password **************

switch(config)#

Sets up remote management in the running configuration of the secondary Cisco Nexus Cloud Services Platform.

ipaddress : the IP address of the CIMC management port

username: the admin username for the CIMC management software

password: the admin password for the CIMC management software

Step 4

show running-config

 

Example:

switch(config)# show running-config
 
!Command: show running-config
!Time: Sat Jun 25 03:01:55 2011

switch(config)#

Displays the running configuration including the remote management configuration for verification.

Step 5

copy running-config startup-config

 

Example:

switch(config)# copy running-config startup-config

Saves the running configuration persistently through reboots and restarts by copying it to the startup configuration.
