Introduction


This documents provides steps to configure IP address for CIMC access to UCS C series servers.

 

KVM Features


Overview of KVM features:

1. Cisco C-Series Rack Servers provides a physical local video and two usb connections for a usb keyboard, video monitor, and usb mouse connection through the front panel of the Rack Server using the Cisco provided dongle connector.

2. All Rack Servers can have up to 4 active KVM over IP sessions in addition to the local connection at front or rear panels. All active sessions have full control of the console

3. KVM over IP supports text and graphics modes of the graphics controller and needs no manual setting to view data

4. Graphics modes supported are up to the video chips maximum capabilities of 1600 x 1200 with 16 bit color.

 

Configure CIMC IP address


Step 1: Boot the server. You will get the following screen.
Note: if you miss the initial CIMC setup follow the unit’s power-up procedure Press (Y) to continue, next Press 9 then Enter to update all.

Step 2: Quickly Press the “F8” key to enter the “CIMC Config” setup before the UCS server goes into auto reboot.

Step 3: For the “NIC mode”, enable “Dedicated” and for “NIC redundancy” enable “None”.  This ensures that the dedicated Management Port will be used for CIMC instead of the Intel NIC at port 1.

Step 4: To use fixed/static IP Address, disable the “DHCP enabled” option.  Specify the required values for three options below :
1.    CIMC IP
2.    Subnet mask
3.    Gateway

Step 5: To use DHCP, enable the “DHCP enabled” option

Step 6: Press the “F10” key to save the changed settings done so far.

Step 7: After 45 seconds, press the “F5” key to refresh the display.

Step 8: Press the “ESC” key to exit the CIMC Configuration Utility.

 

Logging In to CIMC

Follow these steps to login to the CIMC.

Step 1 In your web browser, type or select the web link for CIMC.
Step 2 If a security dialog box displays, do the following:
Click Yes to accept the certificate and continue.
Step 3 In the log in window, enter your username and password.
Step 4 Click Log In.

Is it possible to change the IP address (in my case also network connection information) from the GUI? It seems that I would change the address, mask, gateway, NIC mode and NIC redundancy all at once and hit save.  I should then be able to login using the new network information. Does anyone know if this will work? If so, can this be done without a server reboot?  Thanks.

Yes, you can change these parameters without rebooting the host, since these are all managed by the CIMC.

I would ensure to have someone available locally in case something is not configured correctly and you need physical KVM access.

Thanks for the info - that's good news. I am talking about an ISE appliance and really don't want to do a reboot. I am scrambling to find my KVM dongle - just in case.

Thank you!!! This post help me with my lab.

Hi all,

I'm already install the ucs C220, CIMC and APIC. I can reach the CIMC from web and APIC from kvm.

This my APIC configuration :

HQ_Fabric ==>> OVO-GTN-SIMULATOR
Fabric ID ==> 1
Controller ==>> 3
POD ID ==> 1
Controller ID == 1
Controller Name ==>> APIC1
Address Pool for TEP ==>> 10.0.0.0/16
ID Infra Network ==>> 3967
BD Multicast Address (GIPO) 225.0.0.0/15

OOB
Gateway 10.33.10.1
APIC1 (10.33.10.10/24)

 

My question how to integrate apic (and fabric in there) with cimc ?

 

Thanks and Regrads,

Hello fidogirgazit,

 

Thank you for your question.  Since an ACI APIC is running on a C220 Series Server Hardware, the CIMC is natively integrated.  There is no actions necessary besides setting up the CIMC IP Address as described on this article.

hi,

can anyone please guide me to configure CIMC without rebooting the server.

Hello Akbar,

The only recommended way to configure the CIMC IP address is the method described in this article.  Sorry for the inconvenience.

It is disappointing that we cannot interact with the CIMC from the ACI OS, I see Cisco included the ipmitool open source package in the ACI OS but I get an error when I try to run the command on an APIC. I validated that the driver is loaded so it looks like without TAC support it's a no go.

 

APIC1# ipmitool
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory 

 

I would like basic commands to reset the CIMC and set IP/Mask/GW.

Other vendors offer OS configuration tools from to modify iLO/iDRAC/iLOM
