====== Switches ====== Currently two switches are used in the server room. - Brocade VDX 6740 - Dell S4048-ON ===== Brocade VDX 6740 ===== 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. ---- **Shift License between ports**\\ 24 licenses are available #see which licenses are assigend device# show dpod #release or reserve licenses, interface needs to be shutdown first device# configure terminal device(config)# interface 21/0/17 device(tengigabit 21/0/17)# shutdown device(tengigabit 21/0/17)# exit device(config)# dpod 21/0/17 release device(config)# dpod 21/0/18 reserve device(config)# interface 21/0/18 device(tengigabit 21/0/18)# no shutdown ===== Dell S4048-ON ===== Service Tag: H1K2Y42 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: * ssh emu02-cm.in.tum.de * telnet 10.20.0.2 * * Dell Switch Configuration guide -> {{ :infrastructure:dell-s4048-on_configuration_guide_en-us.pdf |S4048-ON Configuration}} * Dell Switch Command Line Reference -> {{ :infrastructure:dell-s4048-on_command_line_reference_guide_en-us.pdf | S4048-ON Command Line}} ==== Firmware Upgrade ==== The latest firmware can be downloaded from the [[https://www.force10networks.com/csportal20/Main/Login.aspx|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-.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''. * Log in to the switch via telnet ''telnet 10.20.0.2'' * Execute the following commands #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!
