Since I’m living and working in Germany, most of my hardware is using timezone configuration for CEST (or Europe/Berlin). This here is the simple configuration for our Nexus 5000’s: 1 2 3 4 5 conf t clock timezone CET 1 0 clock summer-time CEST 5 Sun Mar 02:00 5 Sun Oct 03:00 60 exit copy running-config startup-config
After rebuilding two MDS9148, I wanted them to correctly switch the summer/winter time for my time zone. Currently I’m in CET (or CEST during the summer), so I googled for that. The search came up with Cisco-FAQ, however that needed a slight adjustment. Apparently the NXOS doesn’t support the feature “recurring” in the clock configuration. So I had to slightly adapt the configuration line: 1 2 clock timezone MET 2 0 clock summer-time MET 5 Sun Mar 02:00 5 Sun Oct 03:00 60
