Setup Infoblox IPAM Express on ESXi

You are running out of budget this moment but you really need an IPAM system to manage your IPs (IPv4 and v6) and leave away the old excel which you worked for a long time. For me using or not an IPAM system will depend of the environment size, it’s need to be reasonable and rational.

This free version supports 2000 hosts and multi-discovery, so not bad for a free product

The requirements to run this version from Infoblox are low (1vcpu, 1GB memory, 50GB), and it’s supported in VMware Player, VMware Workstation or VMware Fusion

I’ve tried convert strait away to vSphere 6 but didn’t work, so i started my journey until get this working, and i did it.

First we need to download the free copy, unzipped and use vCenter Converter to convert the image to our environment and play it.

These are properties i used to setup my IPAM Express

Since IPAM Express doesn’t support a fixed IP, you need get a DHCP working for that subnet

Importing Subnets and Hosts using a CSV file

To import a CSV you will need to respect a strict field format, you can use just a file for subnets and hosts, but i found it insane sometimes. For that reason i imported using different files.

File content subnets.csv

header-network;address*;netmask*;comment;disabled
network;10.1.0.0;255.255.255.0;VLAN1;FALSE
network;10.0.0.0;255.255.255.0;VLAN10;FALSE
network;10.200.50.0;255.255.255.0;VLAN200;FALSE
network;10.100.0.0;255.255.255.0;VLAN100;FALSE
network;200.0.0.0;255.255.255.0;VLAN666;FALSE

File content hosts.csv

header-hostrecord;FQDN;addresses;configure_for_dns
hostrecord;host_NS1;10.1.0.1;FALSE
hostrecord;host_NS2;10.1.0.2;FALSE
hostrecord;Firewall.eth0/0;10.1.0.254;FALSE
hostrecord;FW-DC1_standby.10.0.0.253;10.0.0.253;FALSE
hostrecord;FW-DC1_active.10.0.0.254;10.0.0.254;FALSE
hostrecord;NAS;10.1.0.100;FALSE
hostrecord;DC2;10.1.0.144;FALSE
hostrecord;WSUS;10.1.0.181;FALSE
hostrecord;IPAM;10.1.0.184;FALSE
hostrecord;NAS_NAT;200.0.0.100;FALSE

After a successful import, you will see occupation of each subnet

White box with Cumulus Networks

Probably you heard about “white box” term or Open Networking, which is a new move in the Networking Industry. It’s pretends decouple hardware from software in network device sold by vendor. Have you imagined running NX-OS in x86 server for a network fabric (leaf?) purpose? What do you earn doing this? It would be cheaper off course but you will need Network/Ops teams evolve with that (skill gap?). Some Service Providers like AT&T are moving on white box solutions, they are testing Provider Edge (PE) modes in  MPLS network, replacing expensive boxes from vendors which doing basic functions. At the moment Cisco is not getting there with any product! Juniper is doing some advances, his new product OCX 1100 you can run Cumulus. But what is Cumulus? It’s full-featured Linux OS for networking hardware!
I’ve had an opportunity to play with Cumulus (2 spines/leafs with OSPF, BGP, VXLAN, Bridging), and it seems interesting, but i would expect a more readable CLI. Are we be able to learn another CLI? Absolutely!

Recently Cumulus Networks launch a Virtual Edition called Cumulus VX , it’s available for different Hypervisors, so Network Engineers  will not be in the dark any more. Another benefit with Virtual editions is run a demonstration to customers is a few clicks.

Juniper vSRX 2.0 is out

Juniper released a new version of vSRX (formerly known as Firefly Perimeter) running Junos OS 15.1X49-D15) with more features, and forwarding capacity. The latest version was Junos 12.1 , so moving to 15.1 code is a big jump…I hope it doesn’t hurt!

New Features

The following features are new in Junos OS Release 15.1X49-D15 for vSRX:

  • Naming update: the product formerly known as Firefly Perimeter is now vSRX.
  • vSRX includes DPDK packet I/O support for higher throughput.
  • SCSI virtual disk support has been added to existing IDE support for improved performance and to permit network-attached storage (NAS) integration.
  • vSRX includes SR-IOV vNIC and VMXNET3 vNIC support for greater performance and hypervisor compatibility.
  • vRAM has been increased to 4 GB and vDisk to 16 GB.
  • vSRX includes KVM Ubuntu 14.04 and CentOS 7.0 support to take advantage of Linux improvements and tools enhancements.
  • KVM images are downloaded in qcow2 format instead of the self-extracting .jva script used in previous releases.
  • vSRX includes VMware vSphere 5.1 and 5.5 support to take advantage of ongoing VMware improvements.
  • vSRX includes new architecture based on Linux and Junos OS for performance and flexibility.
