Applications may be installed on your Arista 7130 device. Application installs will persist across reboots. Applications are installed in /opt/apps when using the install process. Presently, MOS ships with the latest stable version of each of the relevant applications, however if there’s a need to install a specific version of an application, instructions are below.
Installing an application from the CLI
- Download the desired software application image as an RPM from the Software Download page. The file will be named something like “application-version.x86_64.rpm” i.e. metamux-0.14.3-1967.x86_64.rpm
- Copy the file to your Arista 7130 device. This can be done in a number of ways. One easy one is to use a USB key, but you could use another method:
[daves@dory ~]$ ssh admin@tad4 Last login: Mon Jun 2 15:36:19 2014 from 10.10.10.101 tad4>en tad4#copy file: file: ftp: startup-config usb: flash: running-config tftp: tad4#copy usb:metamux-0.14.3-1967.x86_64.rpm file:metamux-0.14.3-1967.x86_64.rpm
alternately, via FTP:
7130#copy ftp://gill/pub/metamux-0.14.3-1967.x86_64.rpm flash:metamux-0.14.3-1967.x86_64.rpm 230 Login successful. RETR metamux-0.14.3-1967.x86_64.rpm 226 Transfer complete.
- Now install the new image on to the installed version of MOS:
tad4#conf tad4(config)#install app file:metamux-0.14.3-1967.x86_64.rpm
If the file is in flash or usb, simply prefix with “flash:” or “usb:” rather than “file:”
Application versions are shown using the following command, however after an installation of a new application you will need to log out of the current CLI session, then back in again to see the updated version number.
tad4#show version tad4(config)#show ver Metamako MetaMux 48 Serial number: M48-XX-XXXXX-X Software image version: 0.12.0 Internal build ID: 4783 Applications: metamux-0.14.3, metawatch-0.4.8, netconf-0.6
