The ramblings of a computer geek
At the time of writing (29/03/2024) the recommended EXOS (SwitchEngine) version for the X450-g2, X460-g2 and 5420 (as well as other hardware) is EXOS 31.7.2.28-patch1-75. We recently purchased some new 5420 switches and are upgrading some existing X450-g2 and X460-g2 to the latest recommended software versions. However we have identified an issue that currently at […]

More...You may need to limit bandwidth, perhaps for a customer, or for an area of your network to avoid issues that occur when they saturate links, knowingly or unknowingly. In this example we’ll create a 20MBit Limit with a 250Kb burst, and we’ll make the switch drop anything that exceeds that limit. So in effect […]
More...The Extreme Networks VOSS FabricEngine switches allow for the port partitioning (channelising) of a QSFP28 or QSFP+ port the same as is the case on an Extreme Networks XOS (SwitchEngine) switch. The following example details how this can be completed. The following was used to complete the testing and proof of operation: In this example 100Gbit QSFP28 interface which […]
More...The following can get the errors out for a particular interface (port), in this case we are looking for the InErrors (RXErrors) and OutErrors (TXErrors). For example ID: Only issue i’ve found is that interface errors in VOSS/FabricEngine seem to include RX or TX errors plus annoyingly things like oversized packets. So if you have […]

The capture of network traffic can be useful in troubleshooting issues. Although it is possible to complete this on the switch itself your milage may vary. You require a machine with some packet capture software running and listening on the relevant network interface. XOS In this example we’ll be mirroring port 1 to port 10, […]
More...If you need to reboot a switch at a specific time, you can! Can be helpful for if you were performing a potentially disruptive configuration (where you might get cut off), you can set it to reboot after a specific period of time after you’re going to perform the configuration. Then if the configuration goes […]

We’ve recently started to move to an Extreme Networks VOSS Fabric based network, however due to the scale, we can’t change everything attached to it to work more seamlessly with the VOSS fabric based network operation. We have a large number of hosts for example that use Active-Backup bonding on their NICs when connecting to […]
