Cisco Discovery Protocol (CDP) is used to obtain protocol addresses of neighbouring devices and discover the platform of those devices. This protocol runs on all the Cisco manufactured devices like UCS blades, routers , switches etc. Once you have enabled the CDP protocols on the Cisco UCS , it sends the periodic messages, known as advertisements, to […]

Cisco UCS – How to Configure WWN Pools ?
In Cisco UCS domain , we need to create WWNN (World wide Node names) and WWPN (World Wide Port Names) manually to use the Fibre Channel vHBAs . World Wide Node Name is assigned to the blades and World Wide Port Name is assigned to vHBA (Virtual Host Bus adaptor). According to the cisco notes, A […]
Cisco UCS manager – How to Create the MAC POOL ?
Cisco UCS blades are not encoded with MAC address. So we need to create the MAC addresses, that are unique in their Layer 2 environment and are available to be assigned to vNICs on a server. To assign a MAC address to a blade , you have to include the MAC pool in a vNIC policy. The […]
UCS Manager – Create Sub-Organization – Server Pools – UUID Suffix
Cisoc UCS’s Multi-tenancy method allows you to divide up the large physical infrastructure of an instance into logical entities known as organizations.So that you can isolate between the organizations logically without having the dedicated infra for each environment. Creating a sub-organization is optional, for granularity and organizational purposes and are meant to contain servers/pools/policies of different functions. […]
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 […]
Configuring the Fabric interconnect ports – FC vs Ethernet
In Cisco 6100 series Fabric interconnect , the fixed module ports can be used only for server ports and Ethernet uplinks ports. In other-words , Ports are not unified in this series. But we can add expansion modules to increase the number of uplink ports on the fabric interconnect or to add uplink Fibre Channel ports to the […]
Cisco UCS – Configuring the FC uplinks and port channel
To provide the external SAN access to the UCS environment, it needs to be connected to FC SAN switches or the Storage box which supports the FCoE. Traditional infrastructure will be still using the FC SAN network as a centralized storage. If you would like to connect the UCS domain to an existing SAN network, you have to configure […]
Cisco UCS – Configuring the LAN uplinks and Port Channels
To provide to the external network connectivity to UCS environment,it needs to be connected to the external LAN switches. Fabric interconnect is highly customizable and you have to decide the each port functionality. In the previous article , we have seen that how to configure the server ports to provide the connectivity between chassis and FI. The same […]
How to discover the chassis using Cisco UCS Manager ?
Once you have done the Cabling and Fabric Interconnect’s cluster configuration, the next step would be to configuring the polices and configure ports to perform the chassis discovery. In this article,we will see that how we can configure the equipment policies and discovery the chassis. Once the chassis is discovered , you can see the chassis components like […]
Setup the Cisco UCS environment and configure the UCS ?
This article will provide the step by step instructions to setup the Cisco UCS environment for first time. Cisco UCS is highly customizable and the configuration will be differ for each environment. The core part of Cisco UCS deployment is cabling. Unlike the traditional chassis , Cisco UCS have additional components like I/O modules (FEX) and Fabric […]
