QFX5100 default config
Just for reference, here’s the config a QFX5100 comes with out of the box.
Notes:
Initially the switch tries to get an IP address on the vme0 and irb interfaces so that it can do an auto-image-upgrade, but that failed in the lab since no server (nor the appropriate DHCP options) were available. The result was an irritating repeated message on the console about this. To get rid of that, “deactivate chassis auto-image-upgrade”. This is probably for use if the QFX switch is part of a Q-Fabric – presumably it is trying to upgrade itself over the management network to the version the rest of the QFabric is running.
All interfaces are in the default VLAN, even though their membership is not reflected in the config.
All interfaces have RSTP enabled.
Unfortunately all interfaces are listed twice if they’re dual-mode (i.e. SFP or SFP+). This makes the initial config very long. Obviously this can be deleted.
