How to Configure KVM IP Pool in Cisco UCS Manager ?

The KVM console is a video over IP representation of the blade server. This facility is  required to build and manage the servers from remotely. In an order to access each blades remotely , a pool of IP addresses is assigned as a management interface into the server blades. These IP addresses need to be externally rotatable for remote access to the servers via the KVM console. The IP pools can be created using UCS GUI or UCS CLI method.

 

USING GUI METHOD:

1. Login to UCS Manager .

2. Navigate to LAN  – > Pools – > root – > IP pool ext-mgmt.

 

3. Right click – “IP pool ext-mgmt” and select – > Create Block of IPV4 address.

 

4. Enter the management IP-range for the KVM.

 

Here you can see that IP pools are created.

 

Once the MGMT IP pool is created, you can see that IP’s are assigned to the blades and Rack Elements.

 

If you are familiar with UCS CLI , you can proceed with below instead of the GUI.

 

USING CLI:

1. Login to UCS CLI .

2.  Execute the command like below .

Ex:  create block first-ip-addr last-ip-addrgateway-ip-addr subnet-mask 

ucspe /org/ip-pool # scope org
ucspe /org # scope ip-pool ext-mgmt
ucspe /org/ip-pool # set descr "UnixArena Management IP pool"
ucspe /org/ip-pool* # create block 192.168.201.10 192.168.201.19 192.168.201.1 255.255.255.0
ucspe /org/ip-pool/block* #  commit-buffer

3. Verify the IP MGMT status.

ucspe /org/ip-pool/block # show detail

Block of IP Addresses:
    From: 192.168.201.10
    To: 192.168.201.19
    Default Gateway: 192.168.201.1
    Subnet Mask: 255.255.255.0
    Primary DNS: 0.0.0.0
    Secondary DNS: 0.0.0.0
ucspe /org/ip-pool/block #
