This repository consist of different operations and bindings written using Nornir.
The implied method to run bindings is by executing utils/runner.py and giving it HOSTNAME of a single host to run binding with. If host isn't in inventory, runner will allow you to interactively add it. But it can't add new groups. Run it with --help for more information.
- tors_vrf_check - check different aspects of VRF status on a switch (written for ToR switches) and prints out assumption on its operability; works on full inventory
- switch_interfaces_check - gather different states and characteristics of interfaces on a host
- check_interfaces - consist of functions to get admin/oper state of interface list, assigned IP addresses, number of learned neighbors (IP neighbors, meaning ARP and NDP) and other interace information (description, speed, duplex, load, etc.)
- check_mac_table - grab and count number of MAC addresses learned on interface
- check_vrf_status - check for VRF presence on a switch, build list of assigned interfaces and check for status of BGP sessions in that VRF
Currently more information can be find in function docstrings. First binding was written as part of a blog post that can be found here.
All code is targeted Cisco NX-OS 6 and Huawei VRPv8 V200 if not stated otherwise. Though it may work on other code versions.
click, nornir and all of the dependencies (see requirements.txt). For tests pytest is required.
