Information About Remote Management
You can add remote management to your redundant Cisco Nexus 1010 or Cisco Nexus 1010-X startup configuration so that in the event one of the pair becomes unreachable, the other can automatically attempt to recover it.
If redundant Cisco Nexus 1010s cannot communicate with each other over the management and control interfaces, they can both become active simultaneously. This is known as a split-brain conflict. A Cisco Nexus 1010 cannot be rebooted from its peer switch using high availability.
If one of the Cisco Nexus 1010s becomes unreachable, its peer becomes active if it was standby. If you have configured remote management, the newly-active Cisco Nexus 1010 can attempt to power cycle its unreachable peer switch through the mgmt0 port of its CIMC interface if CIMC is reachable on the peer. The active Cisco Nexus 1010 starts the reboot code immediately when the standby is lost. The standby Cisco Nexus 1010 waits 60 seconds before starting the reboot code.
For more information about loss of communication between redundant Cisco Nexus 1010s, see the Cisco Nexus 1000V High Availability and Redundancy Configuration Guide, Release 4.2(1)SV1(5.1).
For more information about CIMC, see the "Cisco Integrated Management Controller" section.
Configuring Remote Management
You can use this procedure to set up remote management in the startup configuration to be used in recovering an unreachable Cisco Nexus 1010 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 1010. For more information, see the Cisco Nexus 1010 Virtual Services Appliance Hardware Installation Guide.
•You have the following information for the Cisco Nexus 1010:
–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 1010.
•You are logged in to the active Cisco Nexus 1010 in EXEC mode.
SUMMARY STEPS
1. config t
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. show running-config
5. copy running-config startup-config
DETAILED STEPS
| |
Command
|
Purpose
|
Step 1
|
config t
Example:
switch# config t
switch(config)#
|
Enters CLI 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 1010.
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 1010.
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
username adminbackup password 5
$1$Oip/C5Ci$oOdx7oJSlBCFpNRmQK4na. role
network
nexus1010-system remote-mgmt primary ip
172.23.231.51 username admin password **
nexus1010-system remote-mgmt secondary
ip 172.23.231.52 username admin password
***************
|
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.
