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.

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
