Overview In our current implementation, STP is disabled if backup interfaces are used. Loop-protection(LP) agent can run alongside or separate from the STP agent. This will have a method to detect loops and take action based on the configuration by the user. In order to find loops in the system, a loop detection frame will be sent out periodically on each interface that LP is enabled on. The frame will carry broadcast destination MAC address and OUI Extended EtherType 0x88b7 as well as information to specify the origins of the packet. When the switch receives a loop detection frame that’s...

logGrab is a simple bash script that builds a time/date stamped archive containing a number of log items commonly requested when raising a TAC case. It is designed to simplify the process of collecting data from multiple sources within EOS and packing them into a single file for easy upload. The script can be easily extended/adapted and may be integrated easily with other EOS features such as the CLI scheduler and Advanced Event Manager. #!/bin/bash # logGrab - Automatic Log Collector v0.3 LOGNAME=logGrab-$HOSTNAME-$(date +%Y-%m-%d.%H%M%S) mkdir /mnt/flash/$LOGNAME cd /mnt/flash/$LOGNAME ls -alR /persist/sys > persist-sys-contents ls -alR /mnt/flash > flash-contents ls -alR...

A collection of scripts and examples on how to extend EOS using Python can be found in the following repository on GitHub: https://github.com/arista-eosext/
Arista EOS extensions can be easily configured to generate syslog messages. This documents provides an overview of the APIs which can be used in order to achieve that and shows a few examples. The examples presented in the following sections were tested against EOS-4.12.0. Basic example #!/usr/bin/env python # Copyright (c) 2013 Arista Networks, Inc. All rights reserved. # Arista Networks, Inc. Confidential and Proprietary. import syslog syslog.openlog( 'myTestLog', 0, syslog.LOG_LOCAL4 ) syslog.syslog( '%%TEST-6-LOG: Log msg: %s' % 'test msg' ) Result Apr 17 07:15:40 <hostname> myTestLog: %TEST-6-LOG: Log msg: test msg See the official Python documentation for more details.
