I have a network switch which is connected to my Ubuntu Desktop through Ethernet port.

I would like to login into the network switch and execute some commands. Can I use Minicom or is there any other way?

I found Ethernet to serial converters online. But is it not possible to setup serial communication using a plain ethernet cable?

  • Which network switch are you trying to log into? As far as I know, you need Serial to Ethernet for Console ports. But you can use plain Ethernet for NetMgt (Net Management). With a Console port you don't need to know the IP, where with NetMgt you would need to know the IP. – Terrance Jul 5 '16 at 1:44
  • @Terrance Thanks. I am using extreme networks x440 switch. extremenetworks.com/product/x440-series I have connected the console port of the switch to ethernet port of my desktop. I don't have the ip address, so is there no way other than buying the converter? – mk.. Jul 5 '16 at 2:20
  • Summit X440-8t • 8 x 10/100/1000BASE-T (RJ45) ports • 4 x 100/1000BASE-X (SFP) unpopulated ports • 2 x SummitStack • 1 x Serial (console port) and 1 x 10/100BASE-T out-of-band management port – Terrance Jul 5 '16 at 2:31
  • For the Console port you will need a Serial to Ethernet cable. Once you can get into the switch, you can then set the 10/100BASE-T out-of-band management port to the IP of your choice for direct ssh connectivity to it. – Terrance Jul 5 '16 at 2:33
  • Even in the manual I can't seen anything about a default IP address for it. So, from my experience with smart switches you would need a Console connection (Serial to Ethernet) to configure it with first. – Terrance Jul 5 '16 at 2:45

Looking at some of the specifications of the Summit X440 series switches I can see both console and net management ports:

Summit X440-8t

  • 8 x 10/100/1000BASE-T (RJ45) ports
  • 4 x 100/1000BASE-X (SFP) unpopulated ports
  • 2 x SummitStack
  • 1 x Serial (console port)
  • 1 x 10/100BASE-T out-of-band management port

The last port listed is the net management port, but even in the manual I cannot see a default IP address listed. So, from my experience, to configure this switch to allow connection to the net management port for straight Ethernet you would need to connect a console connection (Serial to Ethernet) cable.

Hope this helps!

  • Thanks. I have connected ethernet to management port and will try some standard ethernet addresses that could be assigned by dhcp(192.168.2.xx). I am using telnet.. I will come back if some help needed. – mk.. Jul 5 '16 at 3:19
