1 Administration This information covers tasks needed to properly maintain and upgrade the system running OpenSwitch OPX including system defaults, configuring interfaces, installing Linux packages, logging, and upgrades. System defaults When the system boots up, default system configuration is applied: • All Linux interfaces are created and mapped to physical ports. • All Linux interfaces are in an Administratively Down state.
• opx-show-env — display environmental system components such as temperature, fan, and voltage (see opx-show-env) • opx-show-packages — display specific information for each package installed (see opx-show-packages) • opx-show-stats — display detailed port and VLAN statistics (see opx-show-stats) • opx-show-system-status — display system status information (see opx-show-system-status) • opx-show-transceivers — display information about the current transceiver types (see opx-show-transceivers) • o
If extra security is desired other than what is provided by SSH, use iptables to enable Linux firewall features. You can also set up rate limiting for incoming traffic to prevent denial of service attacks. Configure physical port See the OpenSwitch OPX Configuration Guide to configure physical port attributes. Create user accounts Use standard Linux commands to manage user accounts. Example Linux commands include useradd, userdel, usermod, and passwd. Configure access privileges with the usermod command.

Boot different ONIE mode You can boot a software image from the Linux shell (in OPX runtime) into ONIE. 1 Change the next boot to ONIE using Grub. $ sudo grub-reboot --boot-directory=/mnt/boot ONIE 2 Change ONIE mode to Install, Rescue or Uninstall mode. $ sudo /mnt/onie-boot/onie/tools/bin/onie-boot-mode -o install $ sudo /mnt/onie-boot/onie/tools/bin/onie-boot-mode -o rescue $ sudo /mnt/onie-boot/onie/tools/bin/onie-boot-mode -o uninstall 3 Reboot the switch.
2 Install and configure the Puppet agent on both systems by following the instructions at www.puppetlabs.com. 3 Verify if the Puppet master can communicate with the Puppet agents through the management network. Sample configuration—manifest managing two systems node 'R1.dell.com' { $int_enabled = true $int_loopback = '2.2.2.2' $int_layer3 = { e101-019-0 => {'int'=>'e101-019-0', 'address' => '19.0.0.1', 'netmask' => '255.255.255.
Sample configuration—Quagga configuration file ! This file is managed by Puppet hostname zebra log file /var/log/quagga/zebra.log hostname ospfd log file /var/log/quagga/ospfd.log log timestamp precision 6 hostname bgpd log file /var/log/quagga/bgpd.log ! password cn321 enable password cn321 ! <% @int_layer3.
Nagios Open Source Nagios provides remote monitoring using a remote plugin executor (NRPE), which communicates with the check_nrpe plugin in the Nagios server. This use case describes how to set up a system running the software as a Nagios client (see nagios-plugins for complete information). Configure Nagios client To set up a system running OpenSwitch OPX as a Nagios client, install the Nagios NRPE server and Nagios plugins. The Nagios NRPE server is the agent which allows remote system monitoring.

2 Troubleshooting You can use methods and tools available for gathering information and debugging OpenSwitch OPX including coredumps and firmware versions. Firmware versions To display version information about installed firmware, open the /var/log/firmware_versions file. Transceivers See opx-show-transceivers to view current transceiver information.
