Currently two switches are used in the server room.
The Brocade switch is controlled by the RBG and builds the backbone of the server infrastructure, connecting every server with each other trough a 10Gb/s link.
The switch has an uplink to the rest of the informatics building network and is controlled trough vlans.
VLAN 83 is our chair network (131.159.24.0/23) and VLAN 133 (10.0.0.0/8) is the internal server network. Each interface can be assigned to a specific or multiple VLANs.
There are only 24 licenses, so only 24 servers can be connected with 10Gb to the switch.

24 licenses are available

The Dell switch is used in the Emulation Cluster, connecting the 12 servers with two interfaces each (10Gb/s). The switch has Dell Networking OS 9 running (FTOS10) and is controlled from one Emulations Server (Controller: emu02-cm). The Controller is directly connected to the management port of the switch.
To connect to the switch use the following approach:
The latest firmware can be downloaded from the force10 network. To get a user account a form needs to be filled out on the website with the service tag of the switch and other information. Download the latest firmware of the Switch model (S4048-ON not S4048T-ON !!). The file is something like “FTOS-<Version>.bin” you don't need the ONIE installer file. Check the md5sum of the downloaded file to make sure it didn't get corrupted while downloading. Then transfer the file to emu02-cm.in.tum.de to the home folder of i11 /home/i11
.
telnet 10.20.0.2
#copy firmware file to the switch show file-systems dir flash: show running-config copy scp://10.20.0.1/FTOS-SK-9.11.0.0P2.bin flash://FTOS-SK-9.11.0.0P2.bin dir flash: #check os versions and boot system partition show os-version show os-version flash://FTOS-SK-9.11.0.0P2.bin show boot system stack-unit 1 #safe the config files to the emu02 server copy startup-config scp://10.20.0.1/startup_config_old.conf copy running-config startup-config copy startup-config scp://10.20.0.1/starup_config.conf #actual upgrade of the boot partition #choose the partition A: / B: that is not currently used #in case of firmware failure or unexpected behavior a rollback is easily possible upgrade system flash://FTOS-SK-9.11.0.0P2.bin B: show boot system stack-unit 1 #choose relevant boot partition configure boot system stack-unit 1 primary system B: exit #write config to memory for restart and restart write memory reload show os-version
After the restart you should have a perfectly working Switch with the same configuration as before but with a newer firmware version. Be aware that the reload command takes down all the network Ports temporarily!
