#NO VSTACK CISCO ROUTER INSTALL#
The Smart Install network supports up to seven hops. Note A Smart Install network can have only one director.Ī client switch can participate in Smart Install even if it is not directly connected to the director. Cisco IOS Release 3.2(0)SE and later, support software install.
#NO VSTACK CISCO ROUTER ARCHIVE#
However, any client switch that supports the archive download-sw privileged EXEC command to download a software image can be used in a zero-touch Smart Install network. The most automatic operation is when all switches in the Smart Install network use DHCP and are Smart Install capable. For a client to participate in Smart Install zero-touch update, it must use DHCP, and all DHCP communication must pass through the director so that it can snoop all DHCP packets from clients. In a typical Smart Install network, a client switch uses DHCP to get an IP address and the director snoops DHCP messages. See Appendix A, “Supported Devices for Smart Install” for a list of supported routers and switches, the roles they can play (client or director), and the required software releases. Switches running Cisco IOS Releases 3.2(0)SE and later, and 15.0 (2)SE and later, 3.6.(0)E, and 15.2.(2)E support Smart Install. Smart Install clients can be Layer 2 or Layer 3 switches. Note Switches running releases earlier than 12.2(52)SE are not Smart Install capable, but they can be Smart Install clients if they support the archive download-sw privileged EXEC command. The client can download the image and configuration files from the director TFTP server or from a remote server. These files can also be stored on a third-party TFTP server for the director to use. The director can act as a DHCP and TFTP server and can store the configuration and image files. Reload commands on the client and restart the process. To recover and restart the process, at the system prompt, enter the
#NO VSTACK CISCO ROUTER UPDATE#
Zero-touch updates also take place on preconfigured switches after you have entered the write erase and reload privileged EXEC commands to clear the configuration.Ĭaution If you touch the console keyboard during a zero-touch update and attempt to enter a command or a return on the switch, the auto install and Smart Install processes stop. The director can also perform on-demand configuration and software image updates of a switch or a group of switches in the network. If a standalone switch in the network is replaced by another switch of the same SKU (a switch with the same product ID), it automatically gets the same configuration and image as the previous one. It can allocate an IP address and host name to a client.
When a client switch is first installed into the network, the director automatically detects the new switch, and identifies the correct Cisco IOS image and the configuration file for downloading. The director provides a single management point for images and configuration of client switches. In a Smart Install network, you can use the Zero-Touch Installation process to install new access layer switches into the network without any assistance from the network administrator. You can ship a switch to a location, place it in the network and power it on with no configuration required on the device.Ī network using Smart Install includes a group of networking devices, known as clients, that are served by a common Layer 3 switch or router that acts as a director. Smart Install is a plug-and-play configuration and image-management feature that provides zero-touch deployment for new switches.
