VXLAN for WAN Pseudowires?
by Simon Lockhart 20 Jul '17

20 Jul '17

All, I'm currently going through a network design for an upgrade for one of the networks I run. Much of the wide-area traffic on the network is used purely to transport Ethernet tail circuits back from an edge PoP to a core PoP. Currently we're using Extreme X460 and X670 switches to achieve this, carrying the tail circuits within VPLS. Two things are making me look at a change of solution for this - firstly Extreme have stated that they're not interested in the service provider market any more (and reflected this in significant reductions in discounts), and secondly we need to look at higher bandwidth port options (40G + 100G, particularly for backhaul circuits). As we're primarily a Cisco house, I've been looking at suitable replacements, and the Nexus 9k range looks good - 92160YC and 9236C in particular. However, this would mean a shift from VPLS to VXLAN. We're also looking at Cisco-like products, such as the Arista range. We've been doing some testing in the lab, and so far, things look good - it's easy to configure, and appears to do the job of getting packets from A to B. We do have two concerns, though: 1) Cisco are strongly advising against using the Nexus switches in a WAN scenario - as they're designed for "datacentre" use. They've so far said they can't find anyone who can help validate designs using Nexus, and instead are pushing us towards the NCS-5000 series switches. Same chipset, but 2-3 times the price! NCS does, however, support VPLS, so would be an easier drop-in to our existing network. 2) Traffic engineering - we don't have a lot of requirement for this, but do have a small number of customers who buy A and B circuits, and require them to be routed across different paths on our network. This is easy with MPLS using explicit LSPs, but we've not yet worked out how to achieve the same thing in VXLAN. So, my question to the community is - have any of you used VXLAN as a wide-area layer 2 transport technology? Any pros or cons? Gotchas? Scare stories? Recommendations? Am I trying to shoot myself in the foot? Many thanks, Simon

Temperature monitoring
by Dovid Bender 18 Jul '17

18 Jul '17

All, We had an issue with a DC where temps were elevated. The one bit of hardware that wasn't watched much was the one that sent out the initial alert. Looking for recommendations on hardware that I can mount/hang in each cabinet that is easy to set up and will alert us if temps go beyond a certain point. TIA. Dovid

Zabbix IT Services feature set
by Graham Johnston 18 Jul '17

18 Jul '17

Hi, We have the Zabbix IT Services (running on Zabbix 3.2) configured for some test groups. It usually returns good data but occasionally it seems that one service group or trigger will get stuck in an alerting state and provide an incorrect SLA. This can occur if the trigger has changed to a problem state and then back to OK but the IT services doesn't reflect that change. It will occur where the top level group will show as having 100% problem time and the sub groups and items either have no problem time or such a small amount that it wouldn't indicate 100% problem time. We have it built with some groups under root, some sub groups and items and the items will have a trigger associated with those items. We followed this article to the best of our knowledge: https://www.zabbix.com/documentation/3.2/manual/it_services For Example: |Data Center |-Core1 |--Core1 - ICMP - Trigger |-Core2 |--Core2 - ICMP - Trigger Each subitem is a child of the item above it. We haven't configured any dependencies to any other groups or items. My question is, has anyone gotten the Zabbix IT Services to work correctly? Is there a trick to getting it to work, some configuration we are doing incorrectly? Thanks, Graham

ISP billing - data collection, correlation, and billing
by Sean Pedersen 17 Jul '17

17 Jul '17

I went back a few years in the archives and found a few odd references, but not much discussion. I'm curious what some other approaches are to usage-based billing, both the practice of generating/correlating data and the billing itself. We bill based on use/95th percentile and our system is rudimentary on its best day. We use SNMP and interface descriptions to generate data and correlate it with customers. This works for the most part, but leaves a lot to be desired. Ours is one method, and I've seen others who use NetFlow data in a similar fashion, with the assumption that the NetFlow data is correlated either via IP address or source interface. Most of the systems I've seen are full-fledged CRM, billing, and OSS, which is a little overkill for us at the moment. I think we would have issues trying to integrate such a multi-headed beast into our organization at this time. What methods do you use to collect and correlate data? What systems, if any, do you use? I'm a little in the dark as the billing/OSS side of things is outside of my normal scope and would appreciate any recommendations. Thanks!
