LLDP on Linux

Link Layer Discovery Protocol (LLDP) is an independant IEEE protocol (IEEE 802.1AB) that helps with gathering/ advertising a device’s identity, capabilities, and neighbors. LLDP is Layer 2 protocol. LLDP is usually used on network devices (switches/ routers) to find ‘neighbor’ (connected) devices, but is equally useful on servers to find details of the switch it’s connected to. This is not enabled by default on Linux, but here’s a quick guide to get it working. »

Future of Reliability Engineering (Part 1)

Last month at Interop ITX, I gave a presentation on the ‘Future of Reliability Engineering’. I wanted to break down the five new trends that I see emerging in a blog-post series: Evolution of the Network Engineer (towards Network Reliability Engineers) a) Breaking down Silo’s The network is no longer a silo. Applications run over the network in a distributed fashion requiring low-latency and large data-pipes. With these requirements, network engineers must understand these requirements, understand how applications are generally deployed for troubleshooting purposes and ensure that they have models to plan for capacity management. »

A Postmortem Template

I’ve been thinking about this for awhile and really wanted to publish my own Postmortem Template. You can find the empty template here, I’ll create a filled-out example template in the coming weeks. Please feel free to tweet at me with any feedback »
