This is an improvement the Auto SmartInstall. This feature is very useful when you are provisioning a brand new switch. One has to plug a new switch into a Director and power up the new switch. After the new switch boots up, it will download a configuration template (based on specific model of switch configured) and/or the IOS (again, based on what switch is configured). The next thing one has to do is to customize the new switch, like hostname, IP addresses, port and VLAN assignments, banner, etc. We can configure multiple switch model profile (called built-in group), specify which IOS to use and download specific configuration template. An example of a built-in group is a 24-port 2960S with 2 SFP port or 24-port 2960S with 4 SFP port. Switches that this feature support are the following: 2918, 2960/2960c/2960G/2960S, 2975, 3560/3560c/3560E/3750X, 3750/3750E/3750X and NME-ES network modules for routers. 2900XL/3500XL, 2940/2950/2955, 2970 is also not supported. Routers are not supported either. So what do I need? No biggie. You need a TFTP server of course. A 3560 or 3750 switch running at least IOS version 12.2(55)SE1 IP Base which will act as a Director. Cisco documentation will state that Zero-Touch SmartInstall was introduced starting with IOS 12.2(55)SE but Cisco insiders recommend using the SE1 rebuild because of improvements (aka bug fixes). Anything else? Of course you need the IOS TAR files of the switches involved. You also need to create a few text files. They are: config template The text file is the configuration template for a specific model of switch. Syntax or naming convention would be anything of your choice. imagelist - This file contains only one string: The complete IOS filename (example: c2960s-universalk9-tar.122-58.SE1.tar). The naming convention is a wee bit strange. The naming convention is based on the built-in group (or profile) when configuring the VStack. For example, for a 2960 LAN Lite the filename is 2960-24-8poe-lanlite-imagelist.txt. For a 2960S-24PD the filename is called 2960s-24-2sfp-poe-imagelist.txt and for a 2960S-48LPS the filename is called 2960s-48-4sfp-poe-imagelist.txt. Gotchas? During the entire process, if you do anything, like hit any keyboard while consoled into the client switch (accidentally) the process will stop (hence the term Zero-Touch). This feature does NOT like the / or \ symbols. For example, when you are specifying where the IOS image and/or config template file is located it will only accept this form of syntax: tftp://IP Address of TFTP server/IOS file.tar The syntax of tftp://IP Address of TFTP server/subdirectory/IOS file.tar is going to cause issues and best be avoided. The three files (IOS TAR file, config template.txt file and imagelist.txt file) must be located in the default folder of the TFTP server. VLAN 1 is mandatory. This is because when you get a switch out of the box VLAN 1 is the only VLAN available. If your switch has a Management Port you can use this as well as any switch port. Configuration time! Its simple. Enable VLAN 1: Director# configure terminal Director(config)# interface vlan 1 Director(config)# no shutdown Director(config)# ip address 1.1.1.254 255.0.0.0 Enable SmartInstall on the Director: Director(config)# vstack director 1.1.1.254 Director(config)# vstack basic Configure a DHCP scope for client switches: NOTE: TFTP server IP address is 1.1.1.1/8 for the sake of the demonstration Director(config)# vstack dhcp-localserver badda-bing Director(config)# address-pool 1.1.1.0 255.0.0.0 Director(config)# file-server 1.1.1.1 Director(config)# default-router 1.1.1.254 Connect the link between your Director and the TFTP server into a port configured as VLAN 1. Configure Built-In Groups (or profiles) and specify the location of the IOS image and the config template file: Director(config)# vstack group built-in 2960 24-8poe-lanlite Director(config)# image tftp://1.1.1.1/c2960-lanlitek9-tar.122-58.SE1.tar Director(config)# config tftp://1.1.1.1/2960lite_config.txt OPTIONAL: What if I want to create a few more of this so-called built-in groups because I have a number of different models, for example, 2960S-24-PLD: Director(config)# vstack group built-in 2960s 24-2sfp-poe Director(config)# image tftp://1.1.1.1/c2960s-universalk9-tar.122-58.SE1.tar Director(config)# config tftp://1.1.1.1/2960s_config.txt Connect a new switch to the Director port configured as VLAN 1. Make sure the switch does not have any config. If unsure, console into the switch and erase the configuration (wr erase) and reboot (reload). How does it look like?
