Example for Deploying Zero Touch Devices Using an Intermediate File

Networking Requirements

As shown in Figure 1, newly delivered devices SwitchA, SwitchB, and SwitchC are deployed in a branch and connect to GE0/0/1, GE0/0/2, and GE0/0/3 of SwitchD, respectively. SwitchD is the egress gateway of the branch and connects to the headquarters network across a Layer 3 network.

SwitchA, SwitchB, and SwitchC are different device models and need to load different system software packages, patch files, and configuration files. The enterprise wants the new devices to automatically download required version files to save labor costs of onsite configuration.

The following lists MAC addresses of SwitchA, SwitchB, and SwitchC and the files that the switches need to load:
  • SwitchA: Its MAC address is 0025-9e1e-773b and it needs to load the system software package s57li_easy_V200R019C10.cc (version V200R019C10SPC100), patch file s57li_easy_V200R019C10.pat, and configuration file s57li_easy_V200R019C10.cfg.
  • SwitchB: Its MAC address is 0025-9e1e-773c and it needs to load the system software package s5720ei_easy_V200R019C10.cc (version V200R019C10SPC100), patch file s5720ei_easy_V200R019C10.pat, and configuration file s5720ei_easy_V200R019C10.cfg.
  • SwitchC: Its MAC address is 0025-9e1e-773d and it needs to load the system software package s57li_easy_V200R019C10.cc (version V200R019C10SPC100), patch file s57li_easy_V200R019C10.pat, and configuration file s57li_easy_V200R019C10.cfg.

Configuration Roadmap

The configuration roadmap is as follows:
  1. Configure a file server on the PC directly connected to SwitchE.
  2. Edit an intermediate file to enable SwitchA, SwitchB, and SwitchC to obtain their system software packages, configuration files, and patch files according to the intermediate file.
  3. Save the intermediate file, system software packages, patch files, and configuration files in the working directory of the file server, so that the new devices can obtain these files.
  4. Configure DHCP relay on the egress gateway (SwitchD) of the branch, and configure the DHCP server on SwitchE. Then the DHCP server can deliver network configuration to the zero touch devices across the Layer 3 network.
  5. Power on SwitchA, SwitchB, and SwitchC. They can automatically start the EasyDeploy process to load their system software, patch files, and configuration files.

Procedure

  1. Edit the intermediate file lswnet.cfg.

    # Create a file and name it lswnet.cfg. Write the following content in the file:

    mac=0025-9e1e-773b;vrpfile=s57li_easy_V200R019C10.cc;vrpver=V200R019C10SPC100;patchfile=s57li_easy_V200R019C10.pat;cfgfile=s57li_easy_V200R019C10.cfg;
    mac=0025-9e1e-773c;vrpfile=s5720ei_easy_V200R019C10.cc;vrpver=V200R019C10SPC100;patchfile=s5720ei_easy_V200R019C10.pat;cfgfile=s5720ei_easy_V200R019C10.cfg;
    mac=0025-9e1e-773d;vrpfile=s57li_easy_V200R019C10.cc;vrpver=V200R019C10SPC100;patchfile=s57li_easy_V200R019C10.pat;cfgfile=s57li_easy_V200R019C10.cfg;

  2. Configure the file server.

    Configure the file server according to the server manual.

    After completing the configuration, save the required files on the file server.

  3. Configure SwitchD.

    # Configure DHCP relay.
